a few years ago i programmed a project in PIC assembler which was storing data from a magnetic card reader in a 24C16 using a 16F84.
I have posted the source here:

is brend in world of microcontrollers. So I believe they never be publish something which is not good.
So, try to make more effort to find mistake in your circuit. This programmer is good covered I think.
Any programmer project will not work if you enable to find mistakes.

I am looking for a programmable chip to drive an array of leds:
1. chip should be able to control up to 16 leds or more. probably 0603's
2. chip needs to be very low power. (battery operated)
3. I would like to control intputs to make leds have different patterns
4. A nice function of this chip would be to have a fade effect for led array.
