I use WinXp .How to calibrate ? What 's Vpp ? I'm a newbie ,can you explain it. I just push into "auto_adjust offset and gain" in calibration/test .After that ,there is only 1 value in Vpp (m) for 10V ,11V,12V ,13V ,can't adjust by U-divider >.<
@AdvaRes : this is the image ,programming a PIC 16F877A successfully
the vpp is the programming voltage for pic, the "auto_adjust offset and gain" is what i am talking about.
Do you replace the pic for other equal??
By the way if you cilck in detect pic in programmer the pic is detected???
if the pic is detected check the 10uH coil, check the Vcc after and before the coil, they must be equal.
I had the same problem, and was the coil.
hi i am progamming pic16f877a by brenner8.i select the hex file and load to the pic without any problem and i can see the memory map is full not empty.but when i close
useburn.exe and open it again the memeory map seems empty.i think this means
the pic is empty.the hex file has not been loaded.how can i load the hex file properly.
whot can the problem be? thak u for your help
