my understanding is that loading more code will reduce the freeHeap

@urbiman: used 1.85, added code, compiled, flashed, tested and lost control ....

@user63214 at the moment crypto is not part of the official build, some folks are working on this.

watch https://github.com/espruino/Espruino/iss­ues/807

@Gordon: now it works correct - thanks

good point, using the old version all values look correct

sometimes still returning negative temperature values with that module version, would say this is a ESP specific thing, will try by tomorrow again with a pico

@Wilberforce, sure you can build without errors, but flashing with that image will permanently resting the ESP, just tested with 1v85

@Gordon now I have again time to continue testing with fonts in ROM

old version shows 22.3 and new -22.3

sorry, should show +22.3 and not -22.3

test results for code above on ESP8266

Temp is -22.3 and RH is 35.7

@bigplik

took a copy of your code

got syntax error on first line: "Unmatched '{' ." where does function OLED end ?

ups, to slow, you alread found it by yourself ;-)

@Wilberforce come to https://gitter.im/espruino/Espruino to gitter

yes this JSON contains a lot of information, very helpful.

List of modules in WebIDE - yes.

I saw the entries in the .py files and start asking me, if there is a way to get this information in Espruino, thats all.

yes, may be as part of process.env()

@Gordon sure, will run some test on Thursday

is there a way to list USE_ defines set in .py file ?

eg PICO_R1_3.py

....
 'build' : {
   'defines' : [
     'USE_USB_HID',
     'USE_NET',
     'USE_GRAPHICS',
     'USE_TV',
     'USE_HASHLIB',
     'USE_FILESYSTEM',
     'USE_CRYPTO',
     'USE_TLS'
   ]
....

telnet syntax

telnet [host [port]]

This is more than I expected - thanks !

how to drive 16 tiled pixel square plates (8x8) with GRAPHICS ?

this is what I do at the moment:

build 4 columns, each with 4 plates and address them as four separated 8x32 plates, so everything has to be done four times and more ......

I would prefer to wire them up as zigzag and everything only one time if possible.

Can I overload Graphics coordinate calc function with my own to handle this, or is this mapping already there and I just missed it ?

Anyone else experimenting with more than 3 plates to draw big text, icons, pictures ..... ?

Before sending the init sequence a reset is needed, guess this is OLED specific. Mine is a 128x32 I2C from Adafruit and has a reset pin.

Should be added to the module as optional parameter and toggled before sending the init sequence.

calling connect:

var g = require("SSD1306").connect(I2C1, start,{pin:PIN});

add to module SSD1306:

  ...... 
  var addr = 0x3C;
  if(options && options.address) addr = options.address;

  // reset if pin is given 
  if (options && options.pin) digitalPulse(options.pin,0,5);  // add 

  // configure the OLED
  .....

solved, broken homemade build, have been using a build that generated stars or snow instead of display text .....

After using a new build every thing is working as expected !

If you start building firmware you should add comment to your source to remember you which build you used for that code ....

Use the project icon to add snippets

@Ducky you can have Graphics, but with 1000 instead of 1400 vars and even without fonts in flash
