pic16f877a simulation
I write program for PIC in MPLAB, test simulation in Proteus, all compiling and simulation is okey.
Before load the program for PIC (.hex file) I test voltage's value of all pins.
After load program to PIC, I see that which pins have high value voltage is unchanged, which pin has low voltage have the new value greater than before a little (before: 0.7V then after : 1.03V) and no pins change value from high to low or vice versa.
I check and see that the program is loaded successfully to PIC, but seem that it is mostly like before ???
Could you tell me what problem with it ???
Thanks so much !!!
