Serial

Is there a way to receive data from the serial debugger

[ajh123]

because we can send data blit::debug("Hello, world!");

The other direction is mostly used to send commands to the firmware, but if you prefix with 32BLUSER + uint16 length, you can receive data using the "multiplayer" blit::message_received callback.

Thank you!

Whats the baud rate to connect via Python would 9600 be fine?

[ajh123]

i tried. this python

import serial
from time import sleep
ser = serial.Serial('/dev/tty.usbmodem3271357530391', 2000000, timeout=2, xonxoff=False, rtscts=False, dsrdtr=False) 
ser.flushInput()
ser.flushOutput()
while True:
  data_raw = ser.readline()
  print(data_raw)
  msg = 'Hello?'
  ser.write(bytes('32BLUSER'+str(len(msg))+msg, 'ascii'))

but the 32blit dose not seem to receive 'Hello?', however the python can receive it's messages

[Daft-Freak]

The length is a uint16, so you want something like ser.write(b'32BLUSER'+ struct.pack('<H', len(msg)) + msg.encode('ascii')).

Baud rate doesn't matter (but I guess you worked that out already 😄)

where do i import struct. from im in Python3

[ajh123]

found it, it works now, thanks!

I wonder if this - receiving debug output and sending arbitrary data back - should be a feature of the tools. You could then just import the relevant part of the tools in your code and do something like (very pseudocode here) ttblit.serial.user("message")
