Hi,

You do not say what programming language you are using, if its assembler you can use Nigels tutorial.

You can use either a H-Bridge or PWM or both if needed, but you need to specify the option you want to use.

Hi Wilksey, if he uses an H bridge(hard ware) that would be for controlling direction not speed.Speed is determined by PWM or some other mechanism.PWM is in software.Even if he doesnt use H bridge he will need a transistor(or something else) since a PIC cant run a motor directly.

@Wond3rboy:

Yes, he didnt specify which he was trying to control, you can also get hardware PWM chips, it doesn't have to be generated in software.
A H-Bridge is just 4 transistors anyway, it is the best way for hobbyists to control motors (that I know of).

Hi
Yeah you can, but hes using a micro for that.H bridge IC's are much less tedious to work with than 4 transistors(the simple approach as you pointed out).

If he wants simple control an H bridge and two bits will dtherwise he can use the CCP feature for PWM.
