  • Can anybody help me out on reading a Tach signal from DC fan and controlling an LED on/off. MCU - LPC1768
    See my code, which is not counting/reading external pulse from fan. checking with different fan types but did not get pulse. Please help me to resolve. #include <lpc17xx.h> #include "uart.h" #include...
