KB2040 serial

[solidairsound]

I have a seesaw rotary encoder device connected to a KB2040 (because it was included in my order for free), which i want so send '7,4,1,H' for each positive rotation increment and '8,4,1,H' for each negative rotational increment. The software which this is send to must receive it as such (without apostrophes). Code now:

Code: Select all

import board
import busio
from rainbowio import colorwheel
from adafruit_seesaw import seesaw, neopixel, rotaryio, digitalio

uart = busio.UART(board.TX, board.RX, baudrate=19200)

i2c = board.I2C()
seesaw = seesaw.Seesaw(i2c, 0x36)

encoder = rotaryio.IncrementalEncoder(seesaw)
seesaw.pin_mode(24, seesaw.INPUT_PULLUP)
switch = digitalio.DigitalIO(seesaw, 24)
last_position = -1

panplus = b'7,4,1,H'
panminus = b'8,4,1,H'

while True:
    data = uart.read(7)
    position = -encoder.position
    if data is not None:
        if position > last_position:
            uart.write(panplus)
        if position < last_position:
            uart.write(panminus)
        last_position = position
    print(data)

if possible i would like to send the serial data over the devices usb connection (without the need for a usb-ttl device, although i have one lying around).
the repl shows correct data being written, however the software that i want to talk to is not responding. When using a terminal emulator it does respond the commands (in text).

Any suggestions?
