AD1PCFG bit 14 (PCFG14) Is 0 This register isn't supposed to affect this= pin as it's not an analog input, and I did try setting it to 1, no help. I2C1CON bit 15 (ON) Is 0 OSCCON bits 20-19 is all 0's. (PBCLK divisor - there are several notes ab= out a 1:1 ratio requiring additional conditions). I'm assuming this is still the divided by 8 from the fuses, but could have been overwritten. What does the same code do if ran in the simulator? No idea, I haven't eve= r used the sim yet. Have you gotten a meter out and measured the actual voltage on the actual p= in? Yup, it's low. Almost 0.00. -- David VanHorn Lead Hardware Engineer Backcountry Access, Inc. 2820 Wilderness Pl, Unit H Boulder, CO =A080301 USA phone:=A0303-417-1345 =A0x110 email:=A0david.vanhorn@backcountryaccess.com=A0 --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
