I have development which sends a UART command which my logic analyzer recognized. Now I tried to duplicate this to integrate in my PCB, but I can't get it to work. This is my code: byte buf[8]; buf[0] = 0; buf[1] = 170; buf[2] = 0; buf[3] = 3; buf[4] = 0; buf[5] = 2; buf[6] = 0; buf[7] = 2…

UART does not do what I want
