HPWM on second half

[peterdeco1]

Great suggestion. Quite honestly, I never asked lerameur what his intended frequency was.

[lerameur]

sounds good enough for me, thank you

any way to do a search on microchip website for all chips containing ECCP ?

Does not appear that microchip lists the devices that have ECCP. What size PIC's are you interested in?

The smallest PIC that I am aware of that has at least one ECCP is the 14-pin PIC16F616. As I mentioned earlier, many of the 16F and 18F PIC's have one or more ECCP's.

BTW, I just tested a PIC18F4620 ECCP PWM at 250kHZ (4uS period) in half-bridge mode. The signals on the scope are EXACTLY 180 degrees out-of-phase with each other. Clock was 32MHz - 8MHz FOsc.

The 8-pin 12F615 has ECCP with 2 PWM outputs & deadband.

Thanks, Bruce. I have not used the PIC12 (only use PIC18, PIC24 and dsPIC33) so am not familiar with it.

If your compiler supports the 615, it's worth looking at. My 1st go-round with this one was
a batch of serial motor control ICs for a customer. Very cool little controllers. We use them
for our 8-pin encoder/decoder ICs now. They're nicely priced even in small qty.

PIC24 are also nice, but I'm not really fond of the Mchip 16-bit C compiler. dsPIC I've never
had a need for. I can do pretty much everything we're asked for with a 14-bit core & PBP
or C.

What I really like about PBP is the open library. If you're into the heavy end, you may want
to look at PBP. It's worth the price of the compiler just for the library.

Back in the old days when I used the 8051 core, I would have paid ten times the cost of
PBP for a similar 51 core library.

If you are into open libraries, take a look at Swordfish. Lots more features than PBP and less money. Only for PIC18F though.
