Calculate the amount of delay introduced in the above example of PIC18 timer programming. The value loaded in timer register is FFF1H which is equal to 65521. Subtract it from 65536 … NettetThe timer inside a microcontroller is a free running binary counter. The counter increments for each pulse applied to it. The counter counts continuously from 0 to (2^n)-1 where n is the number of bits. In PIC18F4550, there are 8-bit and 16-bit timers. The timer takes the internal clock as a reference clock, while the counter counts external ... girl on the beach painting
