Heh. Didn't expect that. Very cool :)

Might be a good time to do that vertical step over that JS border and have look at your git repo.

Might still be a nice binary to have pre-built in the Distro / on the web page.

Hm. I'll look into the lib thing and try to make an external module for swapping it in and out from the SD card from it as described in that 935 thread. Otherwise the mem footprint seems not feasible.

I still (or now) wonder if having an STM with crypto capabilities as an option for Espruino might not make sense in the long run. Especially if I consider the discussions on TSL, HTTPS etc and the current state of network modules (hardware). If I stay in my own realm, not having https might not be that much of a problem. However, once I want to connect to other's APIs it might get more important/necessary, and even more so after NSA's work makes many providers tighten their services' security these days.

I saw that Espruino already exists as an executable for RasPi, and since I haven't posted a weird question in a while...

I could imagine Espruino as an executable for desktop OSes as another step. As an simulator displaying the typical ports/LEDs of the supported boards and also for using the host's ethernet. I wouldn't go as far as suggesting to emulate displays and other SPI devices (for now :), but a port of the Raspi-Executable to a Mac OS X/Linux environment might be a nice and easy to add bonus.

Wiznet.eu seems to have a 8 EUR (plus tax) "Design Challenge" Edition (1 per Order/Cstmr?). At least that compensates a bit for their horrendous UPS shipping costs.

+1 for fixing this before my boards arrive.

Hey Gordon,

Sorry, seems I didn't get a notification on this early discussion.

I found md5 in the target libs like here: https://github.com/espruino/Espruino/blob/master/targetlibs/stm32f2/lib/stm32f2xx_hash_md5.c

I'll see if I can (license-wise) use the code I grabbed for providing a module. Still hoping that the link above might lead to having a single JS line instead of filling up the precious JS mem, though :)

Anyone? I just ordered two of the touch screen boards, however I wonder if there are any with a capacitive touch screen or just a screen that is (or will be) supported and is somehow affordable.

Well, unfortunately I had less success, neither with the hub approach nor the resistor idea. I'll see what the oscilloscope view on bat-gnd will bring over the weekend.

Thought that too. .5 amps seemed a bit "safe" :)

@randunel: Hey, thanks. Since one can access Strings on a character level, one can basically implement anything. But given that this is a somehow common function, other people might also miss it. So, might help to have it directly included in the distribution.

Funnily enough I came across it in a function that actually did not need it :)

Appreciated :)

Hey, lastIndexOf seems to be used now and then by some scripts, but is not supported yet. Will it be?
-Stev

Funny. Didn't think of that. Will see how that works out. And if that's actually the culprit :)

Seems my passive hubs here don't provide enough power for my iphone to register. I will see what turns up quicker, a powered hub or that resistor and post the result.

To not build a useless heater, i'll have to get a battery and use that trickle charger setup, it seems. Nice HW design BTW, always nice to see things already in place once you think you might need them.

Cool. onInit is what I was looking for. Thanks. Could have guessed myself.

It's not in the reference, yet, it seems. Just mentioned once in dump() now that I knew what to look for.

Hey,

Hard reset (and load() as far as I remember) work fine. Hard reset was my work around for the time being.

Follow-up: a sequence of reset() and load() works fine, too.

Hey,

everytime I do a save() on my Espruino board, the set button handler is triggered with weird data.

Is there a reason for that? Is there anything in the data that can be used to ignore that after-save trigger?

Best

Hi,

if I'd like to disable the console mode on the BT port if running without a USB connection (for always running an application-specific interface on BT). How would I do that?

Is there an init/setup handler after the boot process? Espruino seems to load every other state fine from flash, but this setting would have to be done by an explicit call.

For now I'm calling USB.setConsole() every time in the onData handler of Serial1 which does not seem to be extremely elegant. Also I'm missing a way of flushing/purging the output buffer of the BT port (it otherwise still will transfer "Console Moved to USB" as well as some initial data on first connect)

Any hints on an boot/init handler and that flushing of the output buffer?

Thanks

Update: a few '& 0xffffffff' have solved the problem.

OTH, while googleing along I found that Espruino has an internal MD5 implementation. Would it be hard to expose that one to the JS level?

I'd like to "vote" for going without Chrome (you even have to register with Google for running the IDE) and maybe go native apps instead (that webkit approach with a lightweight native wrapper might be a good alternative).

Chrome seems a high price for having serial line access.

I am happy with the CLI though, so, just my 2ct, not an urgent matter.

C64, HP48, Espruino.

I programmed a small smooth LED glow (pulse-based dim with modulation of the ratio) as a small test. It is running really smooth as long as the Espruino board is connected to my MacBook.

However, once I plug it directly into an usb power adapter (tried several) I get bad flickering of the LEDs during the otherwise smooth anmation.

I wonder if this is a broken board or just a capacity problem, and whether adding a quartz will help in this particular case.

Any ideas before I go and buy one?

Cheers

Hi,

I'd like to do a MD5 on some data. Unfortunately all the libs I tried return wrong hashes.

Is there any working implementation of MD5 for Espruino? If not, what should I look for on the "differences" part of the JS implementations (I though endianess first, but maybe there are better hints)?

Cheers
Stev
