Hi would one of you mind checking the datasheet make sure I read this correctly to enable the RB0 through RB5 as input and enable the week pullups.
I think I interpreted this correctly
tumbleweed, I would only be looking to have one of 5 pins pulled to ground at any one time so I don't think it is going to be a big concern. I did get the SOIC for the 18F it's not all that big. I...
As I say, If you enable the internal portb pullups and have your jumper/switch either open or to GND then the input will default to logic '1' since it's pulled high.
Tumbleweed perfect I could not remember which was the best way to check for jumper whether high or low what would put the least amount of strain on the power supply while the pic is basically sitting...
If you put your jumpers on PORTB then you can use the programmable pullups on those pins, so all you need is a jumper to GND.
That gives you up to eight jumpers (or just use a PCB DIP switch) w/out...
I'm not sure if this is what your asking but I'd put a high value pullup (10k +) directly to the pin and gnd on the other side of the jumper - so jumper out = pulled up, jumper in = gnd. Do you have...
Ok almost done I think..... Code is working good with a debounce/timeout now using interrupt when sensing proximity. Instead of adding in all kind of code to check and give the user a range for...

Re: PIC USB HID breakout board
The RBPU bit (INTCON2.7) is low-active, so 0=pullups enabled, 1=pullups disabled
