I built a simple one myself. The sending tube is directly connected to IO, and the receiving tube is amplified once with a triode. It seems to be able to receive, but the data is incorrect........ I a...
A very simple program, using the IO interrupt of the key to control the LED on and off on the F5529 development board:#includeint main(void){WDTCTL = WDTPW + WDTHOLD; // Stop watchdog timer
