Hello, sorry for that Noobish Question, but how can i send a UART Message to the M7 back. I connected a Cable on both Pins. Rx and Tx but i get no answer. the read is still None.
Is there anything i miss to implement?
import time from pyb import UART from pyb import LED #LED Control ----------------- red_led = LED(1) green_led = LED(2) blue_led = LED(3) ir_leds = LED(4) # Always pass UART 3 for the UART number for your OpenMV Cam. # The second argument is the UART baud rate. For a more advanced UART control # example see the BLE-Shield driver. uart = UART(1, 19200, bits=8, parity=None, stop=1, timeout_char = 10) while(True): blue_led.on() time.sleep(1000) blue_led.off() uart.write('Hallo\n') print(uart.read(5))
