Questions tagged [icsp]
ICSP is an acronym for in-circuit serial programming. It refers to the ability to reprogram a microcontroller or other reprogrammable device while still in place within a circuit. That is in contrast to devices where the part must be physically removed for reprogramming.

Why did fuse bits successfully reset using ICSP and USBASP programmer?
I read a lot about fuse bits in AVR microcontrollers and everyone says that fuse bits can be reset by using high-voltage programmer only, they can't be reset via UART<->ICSP.
So, I've received ...

Possible to program a PIC18F over ICSP without serial clock?
I'm playing with a device to see if I can program the PIC with my own code. There is a header and I've traced the pins to the PIC18F, but I notice there is no pin on the header that corresponds to the ...

Why 10-pin and 6-pin ISP?
I have another curiosity question:
Why is there a 10-pin AVR ISP connector and a 6-pin version?
It seems that the only difference is that the 10-pin version uses the extra pins for a heap more ground ...
