Hi.

I'm relatively new to PIC's and I have never used the PICF220 before...

I can't understand how to set the I/Os, TRIS and then?

And since I'm already asking, how to set the port(s) to be ADC?

I read in the manual that the internal clock isn't really calibrated, but measured and a correction factor is programmed into the memory.
How to use it properly? (Without overwriting it when programming the PIC.)

PS. The PBP doesn't list the PIC10F220, but I guess choosing 222 will work?


Best regards from a newbie
