flashing avr109 in browser

Description

It’s currently not possible to flash an avr109 protocol device in the browser

Expected behaviour

it should flash like an stk500v1 based device

Actual behaviour

avrgirl-arduino.js:17815 Uncaught TypeError: Serialport is not a constructor

Step by step guide to reproducing the issue

just use your react example and add the board string ‘micro’ or ‘sf-pro-micro’ or anything similar

I never got around to looking into this, but coincidentally I’ve been looking into refactoring my application, and the first part of that is re-writing avrgirl, the stk500v1, stk500v2, avr109, and esptools into a new independent npm package.

I’ve gotten stk500v1 done already and am currently decrypting the spaghetti code that is stk500v2, all with typescript, promises, and automated tests (I envision an RPi with a bank of microcontrollers plugged in that runs all the tests, testing uploads to the actual boards)

@shikshik You can put the Arduino Sketch into bootloader mode by opening the port with 1200Baud, closing it after 500ms: https://github.com/benjaminaigner/avr109-webserial/blob/0aaf0a524e2b29bb7b606b24d267c38a124e6965/index.html#L221 But as we discussed, afterwards the Arduino enumerates again as a different serial port, so you have to select the serial port in the browser again.

One caveat (heavily depending on your Arduino, especially the bootloader version): if you reset the Arduino via it’s own serial interface, the time spent in the bootloader is limited. Pressing the reset button twice extends this time. Reference: https://learn.sparkfun.com/tutorials/pro-micro--fio-v3-hookup-guide/all#ts-reset
