Programming IC2 24LC256

[Squibcakes]

Hi DT,

Well its good to know we can both learn something new, I never knew we could use any pin for I2C... that helps me out big time now. Thanks buddy.

Cheers

Well maybe you just forgot, it have been discussed many times.

I2CREAD,I2CWRITE, SERIN, SEROUT, etc etc, are software solution. AND allow you to use the pin you want. It's no coincidence why you can choose your favourite pin.

HPWM, HSERIN, HSEROUT use the internal Hardware AND don't allow to choose specific pins (except for alternate CCP pin in HPWM)

This is also simple 24lc programmer without extrnal power ,with icprog.

That's a little more than 2 resistors. But it looks like it might be a little safer with the voltage clamping.

Hmmm, self powered too.

I think I'll try it.

You could save few component by using the USB 5V. I already built this interface with USB power and used IC-PROG AND/OR PonyProg for the on-the-road radio decode service. Worked well before i did the decode dongle.
