I have been looking at the pinout of the 16F887 and I cant find the PGD and PGC pins! i was designing a target board for it for when I get my Inchworm+ and I wanted to make a pcb for it. Problem is, i cant find those pins for it! https://www.electro-tech-online.com/custompdfs/2007/09/41291D.pdf
Datasheet for it is above. Thanks
Both will work as part of the inchworm once they are programmed and both can be programmed by the inchworm. Just makes more sense to use the more modern A part. The modern parts are often less expensive and have more features.
I was a bit confused myself.
A case of me reading what I expected to see rather then what you wrote.
Was thinking you were working with 877 when you were using a 887.
As a first chip the 887 is a good choice because of the internal osc.
One less thing to deal with.
I am making a bubler tank for my awesome etchant that rocks and burns really bad, but I wiped it off instead of adding water to it, to prevent exothermic heating, and I want to know where I can get some REALLY cheap Double sided 3x5 or 4x6 boards for etching. Also, does silicon rubber stuff react with my Hcl and H202 etchant?
