Hi,
Not really, but quite close to that... In fact it was a class and I did not found a way to list the source of a class. My trick gets the source of an instance of a class.
All of this happened on an instance of the class runningStats which was itself a property or an instance of the class object stopWatch.

Indeed I deleted the source code in the editor (right side pane) and stupidly saved that incomplete source code to my PC without noticing what had disappeared. Could we get versionning every time we save a source, maybe just renaming the previous same named file with an added time stamp automatically?

The joined file contains that whole thing in terms of: what the little trick gave from the running source on the Espruino, what I finally got after re-editing this dump to get a new version of the source.
Thus I was left with a running instance of my program on the Pico and no way to list it to get back the almost last version of it.
That said, I think it would be nice to be able to reconstruct an object by just a simple dump.

Eventually, some improvements on the editor side would be nice too: something like "Do you want to delete the lines selected" when there are many of them.

Hi,
a) Well other options are not always remembered: the minification options for instance are more or less randomly saved, and so does the time set option.

b) Ok, so this is a feature reserved to the native application: I use the linux one on Ubuntu 16.04.

c) It's just disapointing and onec I got used, yet some thing to do manually. By the way, I would greatly appreciate having an otion to peridically save the source AND journalise those saves (git commits with automatic commit comment would be nice). I guess, reading your answer, that it won't happen unfortunately.

Thank's for your answer.

Hi,
I would like to share this as I had some difficulties some weeks ago and got out of trouble using this:

Here is a recipe to extract the class definition of an object in the console pane.

I used it on a running Espruino Pico which had an objet stopwatch.runningOnStats saved but could not get its source defintion from dump().
It was no more available in the WebIde editor pane because I had wiped it and saved without seeing this before... So I had lost all of the source code for the class runningOnStats property of stopwatch

In the following case, stopwatch.runningOnStats is the object which we want to get the defintion on the console.
We will have to copy/paste/edit the result from the console to get it in a source form

var rs=Object.getPrototypeOf(stopwatch.runni­ngOnStats);
for (var p of Object.getOwnPropertyNames(rs)) {
  console.log(p);
  console.log(Object.getOwnPropertyDescrip­tor(Object.getPrototypeOf(stopwatch.runn­ingOnStats), p));
}

The attached file is a more explicit result and execution trace of what this gave to me.

Hi, this is an old thread, however, I face some difficulties with the WebIde as a Chrome application and just the https://www.espruino.com/ide/.
Here are what they are:
a- In the WebIde settings>Communications, I have to reselect the last option "Set current time" each time the WedIde is restarted from Android. It seems, it is not saved in this configuration.
b- The "Project directory for sandbox" button in Settings>Project doesn't display any select box.
It gets darker a few 1/10 of a second each time i press it. Again that's on Android through the Chrome application and the web served ide https://www.espruino.com/ide/.
c- Saving (disquette button) displays a disturbing "download" message and doesn't let me choose the file name. I get a code(some number).js file in my download directory.

My Android version is 7.0.

I was wondering if there could be some "hidden setting" to properly setup in Chrome?

Thanks for your attention.

Thanks,
Yes, I had forgotten about decimals beeing rounded somewhere when transformed into binaries.

So I tested the second solution and it works.

I totally agree with the no bug approach. The trick is that it's a silent killer. As well as dynamic typing is indeed.

However, the value of v is continuous (risk level in probability) so the exact comparison done by Array.indexOf was not my need.

I finally settled on Array.findIndex as I can get an index through a comparison function even if the value is really not in the array but rather in between values in the array. My array is sorted in increase order.
And this came from your first answer. tab1mAlpha.findIndex(a=>Math.abs(a-v)<0.­­000001)

This page provides the formulas and statistics tables from which I extracted the 2 arrays below...
That gave me:

// approximately computes the xhi2 of 2 degrees of liberty value for alpha risk
  function xhi2_2(alphaRisk) { 
        var idx = [0.05, 0.1, 0.2, 0.3, 0.5, 0.7, 0.8, 0.9, 0.95, 0.99, 0.999].findIndex(elt => elt>=(1-alphaRisk));
    return [0.10, 0.21, 0.45, 0.71, 1.39, 2.41, 3.22, 4.61, 5.99, 9.21, 13.82][idx];
  }
 

Thank's again for your reactivity and commitment to understand our questions!

Hi @Gordon,

While trying to do some statistics, I found that situation on a v2.00 upgrade Pico:

>var tab1mAlpha = new Array( 0.05, 0.1, 0.2, 0.3, 0.5, 0.7, 0.8, 0.9, 0.95, 0.99, 0.999);
=[ 0.05, 0.1, 0.2, 0.3, 0.5, 0.7, 0.8, 0.9, 0.95, 0.99, 0.999 ]
>console.log(tab1mAlpha.indexOf(v))
-1
=undefined
>v
=0.95
>typeof v
="number"

However, using the test box in the mozilla page, I got

var tab1mAlpha= [0.05, 0.1, 0.2, 0.3, 0.5, 0.7, 0.8, 0.9, 0.95, 0.99, 0.999];
var v=1-0.05;
console.log(tab1mAlpha.indexOf(v));
console.log(typeof v);

which once run showed:

> 8
> "number"

So, is this a bug or I am not understanding something?

P.S.: Should I report this type of problem on the forum or in github?

HI @Robin and @Gordon,

Thanks for your help, it did worked and I globally saved some time AND events stack depth.
Now I don't have to separate in time, by emiting events, concatenation, slicing and storing from the Serial.on handler: it just happens fast enough without throwing any event to my Gps object.
In some cases, I could receive enough messages and emit one event per messages, which stopped the program with strange corrupted data in the line received. The result was a buffer way too long (32Kb) and other mysterious unvalid gps data.

Now, I am more on 2 colateral problems:
1-one in Javascript (Serial.pipe chunk parameter in order to limit the number of calls to handler of the input data and get at least any message header at once),
2-one in hardware (Pico powered by 3.7 V battery, deep sleeping as long as possible, using the B0 mosfet with the supplied 3.7 V)

So I think we are far enough of flat strings and should open 2 other threads to handle those points.

Thanks again!

Hi,
As a complementary question to those flat strings handling, I wonder if there is an efficient way to store a standard string (coming from usart for instance) to a pre-allocated flat string without using looping technics?.
This is in order to avoid the allocation time each time my pico receives some complete data packets.

More explicitely, the pico receives some data from usart.
These chuncks are concatenated in Serial.on('data',...) event handler.
So far, these are standard javascript strings.
Once there is enought data, it is sliced and can then be used in a flat string to create an ArrayBuffer resliced itself and finally accessed internally through a Dataview.

The thing is an Ublox M8U gps device using their binary protocol: very c structs friendly and only bytes/words/long words properly aligned. You can see this to get a clear idea. Here, the interest is that payloads are almost all of a fixed length (DMA in sight), very compact (less bytes on usart fro more data) and no fancy sexagesimally odd computations on latitudes/longitudes and so on!

My goal is to preallocate a few different dataviews of predefined length and then copy the incoming data from its string format to the dataview after all checksums and length controls of course.
The gps data will be accessed through getters using v.getUint32(buffer, true) and others as usual with dataviews.

A side approach would be to use inline C for setters and getters but what in Espruino (javascript)?

A dream would be to receive data from serial to an ArrayBuffer (kind of DMA) and only wake up when the serial buffer has enough bytes to analyse: so sleep walking while the interpreter is in deep sleep mode.

Hi,
All of this is why I do use LiFePo4 batteries after, as far as possible, any ldo.
You just don't need them as the batteries will go down from 3.6 V to 3.1 V and charging, as I do it, is at 3.65 V max out of the circuit (removing it from the project and charging separately).
This becomes very important when your main power consumption device is finally close to the ldo quiescent amperage...
Now, some peripherals do have an ldo integrated, and it can be a problem as the LiFePo4 batteries wil dye at 3.1 V while the ldo will reduce its supplied voltage by 0.25 V easily. Not to talk about secondary batteries, poorly designed, which are consuming 13 mA almost permanently. Drones don't care much about nA while we do in this case!

Hi,
Thanks again: the gps has its own voltage regulator so I am just using it as is with the mosfet switching it on & off from time to time.
I expect to use a cheap non protected battery design to recharge a smartphone with a usb connector on its output and a micro usb for recharging it from main. This won't happen while the pico is inserted in the battery.

Hi,
Thank's but I am looking for what happens at partially turned on, not fully on... :)
That said, you are right, almost everything is written but finding it can be more difficult. Gordon is doing a very important job to document and structure this knowledge. However it is a huge task!

I hope so!
Thanks!
Still need to,make sure I wont't have random failures: Data sheets don't always give the needed figures or very undirecly:)!

Hi,
I'd like to use the mosfet of the pico to control power of a GPS (60 mA at 3.3V, 5V tolerant, own ldo regulator integrated).
So, I got confused somehow from the documentation...
That is, after bridging the jumper B0/Fet, I should use the example provided here we have

digitalWrite(B0,1); // Partially turn on the 'Bat' output (this produces 3.3v on the FET, meaning it has just 1.4v between Gate and Drain)
digitalRead(B0); // turn off the output (also check if USB powered)

a-Does that mean that I will get a 3.3V on VBAT?
b-What would be the max amperage in this case?
c-Would the mosfet get hot?
d-On this Pinout, which pin should I use to connect a load that will be powered through B0 controlled mosfet : VBAT, BAT_IN?

As a separate problem, I need to connect the GPS on a UART AND an I2C (addtionnal sensor here).
e-What would the best pins to use: B6 & B7 for UART, which ones for I2C?

Thank's a lot.

Hi,
Sure you can put it wherever you like...
That said I faced difficulties to join it as a simple file from Firefox: for instance I can select the file to be joined but it doesn't appear in the files under my post.
However, it works from Chrome! So...

Hi, 1bitsy is not so far from:
Espruino wifi or Espruini pico!
They are officially supported and do get a long term support...

Hi,
So I did get values around 192 uA - 230 uA while beeing connected, after an NRF.setLowPowerConnection(true) command , display ON and nothing beeing advertising except the Pixl's name.
The fluctuation is probably due to not averaging a long time enough.
Also, I got 50 uA with ldc off with some random reboots on other tries later.
That said it's very comparable to your figures.
So far NRF.setConnectionInterval(200) is not recognised on v1.99...

So the good news is that we will have a very efficient way to save power on the next release.

Hi again,

Edit: some partial conclusions:
While beeing unable to measure some uA situations, I can infer from the figures below that:
a- the "normal" power consumption when no code is beeing executed and display is ON is rather like 300 - 350 uA.
b- switching off the display does save around 70 uA or 20 % from normal power consumption,
c- going to deep sleep saves may be 130 - 140 uA or 40 % from normal power consumption,
d- the Idd from the 32L476DISCOVERY is totally unappropriated to measure varying uAs as it switches from on range to another and interrupts power supply precisely at the amperages in normal power consumption mode with LCD OFF.

Original post:
So my measures are as follow:

Display BLE uart Measure Comment
===== ======= ======= ========

ON connected 570 uA figures are fluctuating ??? BLE UART influence ?
OFF connected 500 uA figures are fluctuating ??? BLE UART influence ?
deep sleep connected 430 uA figures are fluctuating ??? BLE UART influence ? Lower than OFF
back ON connected 570 uA same as ON connected
ON not connected 220 uA jumping between 200 and 590 possibly advertising effects, peaks at 890 uA
OFF not connected 39 uA But reboots with no obvious reason!!! Self ranging ampmeter not switching correctly ????????
deep sleep not connected 37 uA But reboots with no obvious reason!!! Self ranging ampmeter not switching correctly ????????
back ON not connected ? uA Never clear display

Interestingly, reconnecting the ble uart (web ide) OR booting from an usb power bank, does stop all reboots and gives back the same behaviour and figures... So it really seems that the multi meter approach of the 32L476DISCOVERY is in default with those power variations. Unfortunately, the code of this part of the board is not open source: you can not know how measures are by the integrated coprocessor.

I am limited by the Idd functionnality integrated in the 32l476discovery board which is, interestingly, a kind of self ranging ampmeter limited to 50nA - 50 mA at a rather slow rate (1-3 Hz)...
It has already proven to be too averaging to be satisfying in short bursts of power and not replacing correctly an oscilloscope.

About the deep sleep, I didn't cared to add the g.setRotate and g.flip(true) but it does work functionally!

My motivation was to increase the 17 days of autonomy, with a no-name coin cell, by switching off the lcd on a time of day base!

That brings me to some need about an RTC function surviving to resets and code uploads: The IDE offers the time and date automatic setup at code upload but that doesn't survive a reset() which is "illogical" as time never-ever flows back :)

Hi,
As a complement, I used the following code on the Pixl.js.
It allows to switch On/Off the display thus saving the few uA it consumes.
Unfortunatelly, I do not have an oscilloscope and can't measure the real reduction of power consumption, nor any short peak of power when switched on back from deep sleep.

It is a very quick C++ to espruino translation and still contains unused constants... I was about to add this to the standard ST7565 module, when I understood that, indeed, the Pixl.js is using an integrated version probably in C++.

Hi,
Could you consider adding Lora and Sigfox shields?
Albeit long range they are rather energy savvy.

Good, so, i'll disconnect / reconnect after any change in the settings.
Thanks again for your follow up.

Ok, I reflashed with the new cable and it seems to work now...
Sorry for the disturbance!

So I closed the discussion and can't add more posts....
Things are tricking:
Turning off minimification and offline mode imposed me to disconnect and reconnect the board in order to have success. Otherwise, the errors went back as described above.

Then, setting back offline mode does impose the same disconnection/reconnection once only and the problem seems not to reappear: Non errors nor warnings and correct result of 21.

Then turning minimification back to Espruima offline on, did imposed also disconecting/reconnecting once only the board.

Then turning minimification back to Closure online (whitespace only) on, did imposed also disconecting/reconnecting once only the board.

So it could be a problem of stored configuration in the web ide finaly???

You are very reactive and some of our posts got unsynced.
Thank you for that.
Anyway, everythings is shown above.
I don't think it is related to the webide itself, or at least not the last version.
It seems, just an opinion, to be related to serial buffering as I mentionned some cases, which did not appeared here, showed some strings not displayed on the left pane of the webide until I pressed the Enter key.

Now disconnected and uploaded again:
