Besides, the clips take a lot of iterations to get right, which means paying for tool adjustments, plus they require a reasonable [...]
Are you seeing strange behaviour on your PIC microcontroller port pins? Let me guess, you are using ‘bcf’ or ‘bsf’ assembler instructions in your PIC program to change a port pin and for some inexplicable reason it’s just not happening – the pin is not changing? It’s possible that the cause is the read-modify-write feature of Microchip PIC devices. Check out this tutorial and video to shed light on why this strange behaviour occurs, and how to fix it in [...]
