Does anyone using PIC18 know if RE0, RE1, RE2 are actually implemented? It says they are implemented in the textbook but when i use those to take analog inputs the values seem to be floating...
they do work, make sure you set the TRISE register
Hmm yeah it's weird... For me AN1, AN9, and AN10 didn't work properly so I had to test others one by one to see which works and which don't. Also make sure it's not a soldering issue
t I had weird issues with using any of PORT E for input. It works fine for output, but sometimes thinks got funky when measuring input voltage
