Low frequencies measurement
I am new to the forum.
I am recording the RPM, and show it on 4x seven segments with CCP2. It actually works quite well from about 3.81Hz to about 166Hz, which is enough upwards.
I measure the frequency based on each rising edge (waiting for a…

PIC18 Signal Measurement Timer SMT1 (Counter Mode) Not Incrementing
I'm trying to use SMT1 on a PIC18F45K42 to count cycles of a square wave on pin RB0. I can't get the counter to increment, not sure what I'm doing wrong. If I understand correctly, SMT1TMR should be incrementing but it's not. (I also checked…

Force printf to use two characters
I'm using this code on a PIC18 device with the XC8 compiler:
printf("%x", (unsigned char) some_value);
When some_value is below 0xf0, only one digit is outputted, e.g. c for the value 12. On values above 0x0f, two digits are outputted, e.g. 42 for…
