Hi there, I'm trying to get a PS/2 keyboard to work. I have a PS/2 breakout board from Sparkfun. I've double checked my wiring a million times and it seems to be correct. My only change is that I leave the Mouse pins unconnected because I don't intend to use a mouse. Anyway, with this example program: <<code>> #include "mbed.h" #include "PS2Keyboard.h" PS2Keyboard ps2kb(p12, p11); Serial serial(USBTX, USBRX); int main() { PS2Keyboard::keyboard_event_t evt_kb; serial.baud(115200); serial.printf("Alive!"); while (1) { if (ps2kb.processing(&evt_kb)) { serial.printf("[%d]:", evt_kb.type); for (int i = 0; i < evt_kb.length; i++) { serial.printf("%02x ", evt_kb.scancode[i]); } serial.printf("\n"); } } } <</code>> The odd behavior is that the Alive message doesn't print for about a minute. And after it does print, ps2kb.processing never seems to return true as I never get another message. Has anyone else had this problem? What could I be doing wrong? EDIT: Ah, disregard this post. It was a wiring issue after all. I had to use a multimeter to figure out my breadboard has a broken connection across it's power rails
