are you seeing this voltage at opamp out pin with a meter ?
your description is not clear whether the opamp is not working or the adc measurement .
working with opamps with inputs near rail...
The title says it all. I'm trying to utilize the PIC's internal opamp rather than a separate opamp to measure load current on AN6 but I cannot get it to work. I've RTFM so many times I...
I shouldn't but for the sake of the very strange case I will. On both the chips the code is the same except for the port access. Everything else is identical.
Intersting, still ~25% larger compared to 12F675.
The 12F1840 has a larger instructionset than the old 675 so one would think there would be "better" ways to do things on the 1840 (though PBP most...
which is what I did. its a way to break up the flash data space
enabling reading, writing and erasing of data in a pic sized way
yet deal with large data structures normally beyond a pic's...

Hi Richard,

I've been monitoring the output (pin 8) throughout the testing and it doesn't go above ground at any stage. Ultimately I want to process the...
