This is a tutorial about How to program DIP PICs with Breadboard. A BB0703 (PICKit2) is used as a demonstration, however ICD2 and other ICSP programmer can also be adapted.

Thank you very much

 

Thank you for the information

 

Never Better.........

 

Is it just the same with the ICD2? Im trying to programm a 12f629 but am not abel to do this....

The ICD has certain rules if you want to be able to program a PIC in circuit. You have to be careful with what's on the programming pins.

Yes i know and so far i got the pic directly conected to the ICD2 (wich i got from a former employer and it says very dodgy so im not sure it works properly)

Edit:
The ICD2 contains a PIC16F877 if that helps
and here are hte error messages i get

ICDWarn0020: Invalid target device id (expected=0x7C, read=0x0)
ICDWarn0044: Target has an invalid calibration memory value (0x0).

i cant seem to understand exactly what they mean

btw are there any restrictions on the cable length?

According to Microchip, Cable length normally should be around 6 inches. Mine works on 12 inches cable though.

some time the ICD2 requires certain power on sequence, can you connect the ICD2 without target board first, then connect to your target chip.

Also power the target board with external power supply if you can. This will help get rid of many issues. The Microchip ICD2 ICSP interface circuit is kind of "weak" and easy to broke. So make sure all pin-out are correct and connected to the correct pins on the PIC.

The ICSP signal is exactly the same as the ICD2, though the PIN-out sequence is on the opposite way. I don't know why Microchip released the PICkit2 with a opposite pin sequence compare with ICD2.

Please make sure your PC has a good USB power supply or simply power your ICD2 with external power supply. The ICD2 seems working more reliably than power by USB on my personal experience.
