The 16f737 has an A/D module, and on some of the RB pins are analog inputs.

Look in the 16F737 data sheet under the "ANALOG-TO-DIGITAL CONVERTER (A/D) MODULE" section for the value to place in ADCON1 that allows these pins to function as digital I/O-pins.

Then you place ADCON1 = x in your code, (where x = the value shown in the data sheet) to turn off the A/D function for pins associated with the A/D module.

On power-up ADCON1 = %00000000 and this makes all pins (associated with the A/D module) analog inputs by default. You just need to change this to configure whatever pins you need as analog or digital.

Bruce you are way too cool. Thanks.
I knew it had to be something I wasnt thinking of. I have read through these datasheets, but for a beginner, there are a lot of terms in there that just plain dont make sense, so until someone points it out as a problem, it just doesnt click.

A lot of people on the forum say to just look in the datasheet, your answer is there. But somtimes it does take the extra explaination that you gave to really help.

along the same note, I am using a 16x1 display. In the manual it states that 16x1's are usually treated as 8x2's. When I try to write something longer than 8 characters it doesnt work. So I tried jumping to line two to continue the word and it still doesnt respond. Do I need to be running in 8bit mode to use all 16 characters? Here is the code

LCDOUT $FE, 1, "L.E.A.D.", $FE, $C0, "S."





cheers!
