Sending text to display no longer working? < board.send_sysex( STRING_DATA, util.str_to_two_byte_iter( text ) ) >

[nildude]

Hi fellow tinkers,

I am suddenly having issues writing outputs to my DF Robot 2x16 LDC display. I was previously able to direct all text messages to the display but installing the latest version of pyFirmata has resulted in text not showing up:

I am using the board.send_sysex( STRING_DATA, util.str_to_two_byte_iter( text ) ) method.

I am not getting any error codes and not sure how to further troubleshoot?

The python code looks like this:

import pyfirmata
from pyfirmata import Arduino, util, STRING_DATA

# Setting up Arduino
if __name__ == '__main__':
    board = pyfirmata.Arduino('COM4') # '/dev/ttyACM0'
    #board = pyfirmata.Arduino('/dev/ttyACM0') # '/dev/ttyACM0'
    print("Communication Successfully started")


it = pyfirmata.util.Iterator(board)
it.start()

def msg( text ):
    if text:
        board.send_sysex( STRING_DATA, util.str_to_two_byte_iter( text ) )

if __name__ == '__main__': 
 msg('Testing test')
 msg('Second line') 

Thank you for your assistance.

Best regards
Lars Henrik

It seems like the "Firmata.attach( STRING_DATA, stringDataCallback);" function is not receiving the STRING_DATA object? Any ideas?
