PIC Controllers (once again)

PIC Controllers (once again)

PIC Controllers (once again)

(OP)
I have to make an impuls generator. In a given period I should be able to produce up to 4 pulses at any time in the time lapse. One should be able to alter the frequency, so the period reduces, but the proportions should remane the same.
I could use some helpfull tips, because I've never worked with PIC controllers before. I have some experience with assembler. I could also use some examples on how to program the PIC, some other programs, examples and solutions.

RE: PIC Controllers (once again)

I assume your referring to Microchips microcontrollers. Their website is packed with examples. What you want should be similar to any PWM code on Microchips website. www.microchip.com
Depending on which unit you select(look at 12c508 if all you want is some IO with no AD or DA converter), they can be programmed in circuit (flash or ISSP). You can get the software for free from their website but the programmer you will have to buy unless you have time to construct one of the million versions of PIC programmers. The off the shelf unit costs $199 from Digi-Key. Good luck.
