Hello,
oh I just realised that there was in fact a bit shifting error in the
readADC() routine. Embarassing. I did not see it the whole day. OK
now the data is correctly transferred into the PIC, next thing to
check will be the multiplication (because the values are still off by
about 20V). Or
And another follow-up: I realised my offset was in fact a linearity
error, so I tweaked a little bit, and a correcting term of 0.004 / Bit
did the trick. Is this ethical? ;-)

I have a small IC caddy full of ICs I believe to be logic ICs. Look a
the link I have attached, the pics are high resolution, so you can
make out part numbers. If you want them, let me know, they are of no
use to me. Pay for the shipping, and they will be delivered
promptly. I only ask the
