    Exclamation Max6675 And 16F877

    Hi i am trying to use the max 6675 temp chip but looks like it keeps freezing. I can get 1 temp reading but no more. My question is can i read serial data on any pin with the 16f877

    thanks

    If you are using software serial (SERIN/SERIN2) then yes if the ADC and comparators (for the "877A") are shut off. Can not remember if the 877 has comparators. Check the DS.
