Hmm, 315 milli-Hertz, 0.3Hz, 3-second period, must take a long time for the full code to get through. Maybe you didn't wait long enough?

Thanks, - Win

transmitter side LPC 2106 message is may day may day EP-3 .... repeat



db-9



pin2 txd pin 5 gnd



push the reset


receiver side is connected a DB-9 and realterm, 9600 XP windows based system ( any rate that I possible that I can think of) 8n1 .



use usb 5V power



pin 3 rxd



pin 5 gnd



result: nothing, no garbage in realterm what so ever and I do not know why?



the lpc 2106 microcontroller run very steadily, unplug everything



both modules are about 1 meter apart, try tera term too. no results. any comment.
