Hi all,
I have a problem when trying the ICSP function of UIC00B with PIC16F877A, and I hope can get some hints and suggestions from you. When I connect my target board with UIC00B, I got the message box saying "PICKIt 2 VPP voltage level error. Check target & retry operation." It was mentioned in the troubleshooting section in the manual that no capacitor should be connected with MCLR pin of the PIC, but a 0.1uF capacitor was used in the figure on p.36.
As I do not have electronic background, I do not really understand the purpose of using the capacitor... and I cannot thus know whether I need the capacitor or not... In addition, do I need to connect the RB3/PGM pin to the ground (it was mentioned in one of the example PR7_DD.pdf)?
Many thanks if anyone can help!
