View Full Version : Getting back into the PBP saddle after a long absence

I haven't used PBP in nearly 8 years. Micros have come a long way since then and back in the day I would use a 16F88. It was a great little micro, but for my one of projects, it would simply run out of space. My question is is there a general purpose micro, as easy to use, that is 32 bit, with maybe 32k of code space so resources are never an issue? I am looking for a dev kit I can just buy.

I like 18F2xK22 series when I don't need as many I/O, 18F4xK22 when I do.
On phone, no idea what exacts specs are.

If you're looking for 32bit devices then forget PBP - it only works for 8bit devices.
With that said there are plenty of 8 bit devices much more capable than the old 16F88 but without knowing what you're looking for (peripheral, number of pins etc) it's hard to provide any specific advice but for a general purpose device perhaps the 18F26K20 might be a good start.
You can use the device selector on Microchips website to sort and filter on the specific details you're looking for.
/Henrik.
EDIT: Pretty much what Robert said, in other words - he replied while I was typing slowly....

Oh yeah, these puppies can run up to 64 MHz.

Thanks for the suggestions. I really don't need 32 bit, just more space. I just figured for a one off project I don't care about cost so whey not just start with a Porsche. To be honest with you I design many boards in the millions but never look at microchip. I just have this programmer from college and figured for running a flow meter, motor and small LCD it's good enough as my SW background is weak.

When in need of more space I have used the 18F67K22 it has 128K which has come in handy a few times. I mostly use the 18F26K22 for larger projects and for the smaller ones 8K or less the 16F1825 and 8 pin version w 4K the 12F1840.

Is there a good development board with those micros.

Dave, have you ever gotten a DS1620 thermal chip to work on a 18f26k22? I have tried on Ports A-C and cannot get this to communicate correctly.

Never mind, I first have to initialize the DS1620 ;)
