PFS122 support #52

Open spth opened 3 years ago

spth commented 3 years ago

A while ago, Padauk released the PFS 122.

Since this is a flash device, I'd expect it to be popular among hobbyists, and it would be good to have support for it.

I am happy to pay a bounty and support testing if PFS122 support can be added

JS added PFS122 to the development branch last week! So you can start testing it out. It seems like the PFS122 is just a PFS173

kibix commented 1 year ago

Yes, thanks for the hint ! I tested today with the previous version, selecting the PFS172 (that is also as what the chip identifies), and it programs well. The include files for SDCC are missing a register for the PFS122 (which has 16bit results from AD, compared to 8bit on other models), but that is, obviously, trivial to fix.

So i can confirm that even without a specific PFS122 setting, the chip can be correctly programmed by selecting PFS172.

Cheers

I think the PFS172 may have already had a 12bit ADC. For the PFS173 they discovered at least 11bits of the adc https://free-pdk.github.io/undocumented-features#11-bit-adc-pfs173. If you have an PFS172 you can try to read the lower adc bits from the adress 0x23!
