Using a Shadow to Create a Light Seeking Sensor

in Projects • 6 years, 9 months

Light Seeking System

Two photo resistors are positioned on opposite sides of a rectangular beam. It the beam is pointing at a light source both photoresistors produce equal values. If not aligned this balance is upset by the shadow of the beam and the difference in photo resistor output is used to rotate the beam using a stepper motor.

console.log blocks action when disconnected from WebIDE (or a terminal program)

in JavaScript • 6 years, 9 months

If you use console.log in a program but disconnect the program execution is blocked when the console buffer is full.

For example:

// Console.log blocks LED On/Off flashing when
// disconnected

var l=0;
myinterval=setInterval(function () {
   digitalWrite(LED1,l=!l);
}, 1000);

var i=0;
setInterval(function(){
  console.log(i);
  i++;
},200);

// load program
// LED is pulsing On an dOff
// Console is displaying the count in i
// Disconnect the WebIde
// The LED action stops
// Reconnect the WebIde
// Buffered count is displayed
// LED resumes action

and the output:

If you are using console.log to show the connection status etc. of a WiFi connection, disconnecting the WebIde will block the server.

Not complaining about this, just posting to let others know about this gotcha.

A WIFI Datalogger for Espruino PICO

in Interfacing • 6 years, 10 months

Using the PICOwifi.js Module

Require and create an instance of PICOwifi

var X=require('PICOwifi');
var Y=new X();

Setup some variables

// things to configure
var ssid="your network name";
var key="your network password";

// used by PICOwifi module
var Startagain=0;
var myinterval;
var verbose; //module is quiet
//var verbose=1; // module console.logs

Create a task or a series of tasks

For example:

var page1 = "<!DOCTYPE html>\r\n<html>\r\n<body>\r\n\r\n<h1>My First Web Page</h1>\r\n<p>My first paragraph.\r\n</body>\</html>";

function mytask(){
 console.log("Mytask");
//// Various user code can go here a simple hello page server
//// is given as an example
var http=require('http').createServer(function (req, res) {
res.writeHead(200);
 console.log("hello");
 res.write(page1);
 res.end();
 res.on('close', function() {});//console.log("t2close");  });
 req.on('data',function(data){});//,data);});
 req.on('error',function(){});//console.log("reqerr");});
 req.on('close',function(){});//console.log("reqcls");});
}).listen(8080); //end server
//// end user code  
}//end my task

Setup function to start the wifi and check it periodically

function test(){
    Y.connect(ssid,key,mytask);
}//end test

myinterval=setInterval(function () {
//  console.log("Test for error");
  if(Startagain){
   Startagain=0;
   test();
  }//end of Startagain
}, 2000);

test();

The Startagain variable can be used in the task code to cause the WIFI to restart. A tasknumber could be used in Mytask to take the tasks through a series of tasks

A WIFI Datalogger for Espruino PICO

Using the ringMod.js Module

Assuming that the ringMod.js module is located in th emodules folder of the WEBide sandbox.

Require the module in your code and for convience use a variable to specify the length of the rinf buffers.

var R=require('ringMod');
var dsize=432;

Declare an array of pointers to instances of ringMOD and then create the instances

For example:

var data=[];
data.push(new R("Date",dsize,Array,1,1,0,gettime,null,datestring,0));
data.push(new R("Temp F",dsize,Int16Array,100,9/5,32,E.getTemperature,null,tofixed,2));
data.push(new R("Temp C",dsize,Int16Array,100,1,0,E.getTemperature,null));
data.push(new R("Flow l/s",dsize,Int16Array,4096,1,0,analogRead,pinB1,tofixed,2));
data.push(new R("Pump",dsize,Int8Array,1,1,0,digitalRead,pinB3,tofixed,0));
data.push(new R("dhtTemp C",dsize,Int16Array,100,1,0,getTemp,null));
data.push(new R("dhtRH %",dsize,Int16Array,100,1,0,getRH,null));

The fields used when creating instances of ringMOD

ring(hname,size,type,mult,slope,intercept,logfunc,lfargs,format,fargs){

hname - a string that is used for the column title in the final spreadsheet
size - the length of the ring buffer
type - the data type used to store the data. Examples Int16Array, Int8Array etv
mult - multiplies the raw data before storage, divides the stored value before using
slope - the linear regression slope used to scale raw values into engineering units (non-zero) If in doubt use 1.0
intercept - the linear regression intercept used to scale raw values into engineering units (try 0.0)
logfunc - name the function or helper function used to obtain the raw data. Examples:
```
function gettime(a){
return clk.getDate();
}
```
lfargs - any argument needed to complte the logfunc. Example logfunc= "analogRead" and lgargs= B7, if not needed use null

format - name of helper function used to format the data Examples:

function datestring(a){
//  console.log(a);
return Date(a).toString();
}

function tofixed(a,b){
return(a.toFixed(b));
}

fargs - argument used with the format function: For example format =tofixed and fargs=2

Inserting the data

Note the logflag used to suspend logging until the clock etc are ready to log.

function log() {
 var i;
 if(logflag>0){
  for(i=0;i<data.length;i++)data[i].insert();
   digitalWrite(LED1,l=!l);
 }
}

Logging the data

The DHT22 returns data in a callback so call it first and in the callback save the DHT data and do the log()

// Do the logging at loginterval in ms
setInterval(function(){
dht.read(function (a){
 DHTt= a.temp;
 DHTrh= a.rh;
//  console.log("Temp is ",getTemp());
//  console.log("RH is ",getRH());
 log();
});
},loginterval);

The DHT temporary storage variables and the logfunct helper functions

var DHTt,DHTrh;
function getTemp(){return DHTt;}
function getRH(){return DHTrh;}

Creating the CSV data from the data array

The process.memoy() commands fix a bug that the cutting edge version of Espruino has fixed.

Send 10 lines at a time in the drain function to keep from using too much memory at a time.

function onPageRequest(req, res) { 
    var i=0;
    var ii=0;
    var j=0;
    var sss="";
  var a = url.parse(req.url, true);
if (a.pathname.substr(-1)=="/") { // a slash at the end
    res.writeHead(200, {'Content-Type': 'text/html'});
// substitute your own html here
// maybe a button to clear or reset the data log on the Pico
    res.write(page1+DweetID+page2);
process.memory(); 
    res.end();                                
}else{ //filename.csv after the URL slash to do csv files
process.memory(); 
console.log("dl");

Items to edit in order to run the examples:

Local Modules

In the upper right of the WebIDE is a 'gear' looking icon, hover the cursor over the icon and the word settings will appear. Click on the settings icon and then select Project. Use the "Select Directory for the Sandbox " to select or even create a sanbox directory. For example I create a sandbox named EspruinoModules. It has a number of sub-directories. We are interested in the one called \modules.

"C:\Users\jj\Documents\EspruinoModules\modules"

Copy the attached modules files to the folder:

"C:\Users\jj\Documents\EspruinoModules\modules\PICOwifi.js"

and

The verbose refers to console output in the PICOwif module.
dsize it the length of the rung buffer used to store data.

loginterval is the number of milliseconds between data samples.

Which hardware does this work with? Don't the register addresses depend on the hardware platform? It would be cool to use this with an audio codec to record or play waveforms.
Is it possible to run WebIDE run on a Raspberry PI and programa PICO etc?

in General • 6 years, 10 months

Since the Linux environment of the RP can be used to compile Espruino, is it possible to flash the chips and then run WebIDE on the RP and program the chips in Espruino.?

It's likely that the RP would need a USB hub extender in order to power the chips.
Have I bricked my esp32

in ESP32 • 6 years, 10 months

It's sounding like it really is a brick.
What do you have it connected to?
Chip, power, USB cable?
Other circuits?
Use Voltmeter to confirm 3 Volts. Do the LEDs flash when you plug it in?
Is the USB cable functioning with some other device?
If connected to other circuits can you disconnect and try it?
Certain pins have to be at the correct levels to program the chip.
Some other pins may be used by the SPI mode to talk to the flash chip.

If you are using an Arduino kit to program it does the kit work with another device?

Have I bricked my esp32

in ESP32 • 6 years, 10 months

Try it without specifying a baud rate. I think ESPtool.py will try and find one that works.
For example this batch file to read the chip info:

:: Read ESP8288 or ESP32 chip info
set /p pport=Enter a Com port 
echo %pport%
pause
esptool.py --port %pport% --no-stub chip_id
esptool.py --port %pport% --no-stub read_mac
esptool.py --port %pport% --no-stub flash_id
pause

Wifi.connect() not executing its callback function

in ESP32 • 6 years, 10 months

Here's another one closer to your version:

//ESP32wifi1.js
// 5 Feb2018

var ssid="sasas";
var key="password";

console.log('start');

var wifi = require('Wifi'); 

var onWiFiConnect=function(){
  var IPobject = wifi.getIP();
  var IP = IPobject.ip;
  var MAC = IPobject.mac;
  console.log("IP:");
  console.log(IP);
// if IP is 0.0.0.0 failed to connect have to reset to clear 
  console.log("MAC:");
  console.log(MAC);
};
 
wifi.connect(ssid, {password: key},onWiFiConnect());

And the output:

Have I bricked my esp32

Other than trying all the baud rates, can't think of anything else.
Try 9600,19200, 38400, 57600, 74480.

Did you ground GPIO 0 and do a reset to put the chip into flash programming mode?

At first your code wouldn't load and would complain the module wifi was not found.
The cure was to exit WebIDE and uplug then start over.

Espruino code will not push to ESP

in ESP32 • 6 years, 10 months

Try bringing up WebIDE and clicking on the "gear" (settings) in the upper right. Now click on communications and check to see if the baud rate is set to 115,200.

Here are the batch files I used to flash my Sparkfun ESP-32 Thing board.
Put them in the same directory as the ESP-32 files. From the file explorer click on the batch files to execute them.
First find out about the flash memory on the chip by running the ESPinfo.bat file

:: Read ESP8288 or ESP32 chip info
set /p pport=Enter a Com port 
echo %pport%
pause
esptool.py --port %pport% --baud 115200 --no-stub chip_id
esptool.py --port %pport% --baud 115200 --no-stub read_mac
esptool.py --port %pport% --baud 115200 --no-stub flash_id
pause

You have to enter the com port as "com3" (no quotes in what you type)

Next run the batch file EraseFlash.bat

:: Erase flash
set /p pport=Enter a Com port 
echo %pport%
pause
esptool.py --port %pport% erase_flash
pause

Finally run the file FlashESP32.bat

:: Flash ESP32 chip with Espruino
set /p pport=Enter a Com port 
echo %pport%
pause
esptool.py --port %pport% --baud 57600 write_flash --flash_freq 40m --flash_mode qio --flash_size 4MB 0x1000 bootloader.bin 0x10000 espruino_esp32.bin 0x8000 partitions_espruino.bin
pause

I just noticed that you use flash mode dio. I used qio in the batch file.
ExpressIF produces devices with various flash memory chips that vary in size, speed and spi communications method. That's the difference in qio and dio.
Figuring out what kind of flash your device has is the basic problem. When I buy a new ESP8266 or ESP-32 I like to use putty to bring up the initial screen using 115,200 and 74,480 baud. The information displayed usually tells me the flash size and spi mode, never seen anyting about the speed. If you do this first you will know what the factory used.
Here's what I get from Putty and WebIDE after flashing with Espruino. Connect and press reset button on the ESP32 board.

A question for @MaBe. Does the memory size 4MB-c1 apply to ESP-32?

Espruino code will not push to ESP

in ESP32 • 6 years, 10 months

Have you tried connecting with Putty?

look here

Also try putty at 74,480 Baud as some chips start here to display the boot info and switch to 115,200 for the Espruino logo.
Sometimes you have to exit WedIDE and unplug the chip and start over to clear the problem.

Problem with E.toString in Espruino 1v95 on ESP8266-4MB

in ESP8266 • 6 years, 10 months
It were the watchdog timer doing the reset.
This works.

var chk=1024; var tdata=new Uint8Array(chk); var i=0; tdata.fill(0x30); function draino(){ } D=new draino(); D.on('drain',function(){ console.log(i);i++; console.log(E.toString(tdata)); process.memory(); //fails if this is commented }); setInterval(function (){ D.emit('drain'); },100);

The emit and drain are simulating serving data to a socket.
Code for doing that would obsfucate the issue a bit more.

Gordon has addressed the problem shown by commenting out the process.memory, but his fix isn't in the published 1v95 code yet.

Thanks for the tip about the watchdog. The ESP8266 Espruino is a different paradigm from the Pico. Is there a similar watchdog in the ESP32 Espruino?

Give that a try.
If you get Espruino up and running then in the left window of WebIDE try to following commands:

require("ESP8266).getFreeFlash()

and then

process.env

Esp8266 erase flash.

in ESP8266 • 6 years, 10 months

Try using the files in this directory

\espruinoEsp8266Flash\espruino_1v95_esp8266

not this directory

\espruinoEsp8266Flash\espruino_1v95_esp8266_4mb"

You might want to switch to ESPtool.py (Linux or windows)
I used to use the ExpressIF tool but switched to ESPtool.py because I can use batch files to do the flashing in a few mouse clicks:

One gotcha is the ExpressIF tool flash size is given in bits, ESPtool.py uses bytes.

Finaly got a 4MB ESP8266-12 (AI-Thinker ESP8266 MOD) assembled and working.

I used 10k pullup resistors on the reset, Enable and GPIO 0 pins and a 10k pulldown resistor on GPIO 15.
I used three batch files to run the ESPtool.py
I first copied the batch files to the folder:
"C:\Users\jj\Documents\espruinoEsp8266Flash\espruino_1v95_esp8266_4mb"
Run the batch files by clicking on them in file explorer after grounding GPIO 0 and resetting the chip.
Run ESPinfo.bat and get the following.

Then I did a reset of the chip and ran EraseFlash.bat.
Then I did a reset of the chip and ran
"C:\Users\jj\Documents\espruinoEsp8266Flash\espruino_1v95_esp8266_4mb\FlashESP8266_4M_40mhz.bat"
I un-grounded GPIO 0 and reset the chip.
Reconnect to WEBIDE and try the test program WSDesp8266C.js
It connects to my router and serves the HTML page but fails to transmit data via WebSockets.

Try again

Put the batch files into the following folder
"C:\Users\jj\Documents\espruinoEsp8266Flash\espruino_1v95_esp8266"
Rerun the ESPinfo.bat, EraseFlash.bat and FlashESP8266_4M_40mhz.bat.
The WSDesp8266C.js program produces the following output:
