Common Problems
Communications cannot be established with MPLAB-ICD.
If you cannot establish communications with MPLAB-ICD, follow these steps:
1. Make sure there is power to the demo board/target application.
MPLAB-ICD is powered by the demo board/target application. Also, if
you are using the demo board, make sure the power supply has the correct rating (9.0V, 0.75A).
2. Check that the MPLAB-ICD Header is plugged in to the demo board/target application correctly, e.g., all header pins are plugged into the socket
and the header is correctly oriented. Also, make sure you are using the
correct stand-off if you are using the demo board.
3. Check that the PIC16F87X is plugged in to the MPLAB-ICD Header correctly, e.g., all pins are plugged into the socket and the PIC16F87X is
correctly oriented.
4. Check that the connection between the MPLAB-ICD and the host computer, via the RS-232 cable, is secure.
5. Check that the connection between the MPLAB-ICD Header and
MPLAB-ICD Module, via the 9-inch modular cable, is secure.
6. Check the settings for MPLAB-ICD in the Development Mode dialog
(Options>Development Mode) in MPLAB. Make sure you selected the
correct PICmicro, COM port, and baud rate for your application.
If communications still cannot be established, contact Microchip Customer
Support, as described in General Information.
