Using male DB9 connector
The PDF states that only female DB9 connector should be used. In printed circuit board shown in this PDF only few modifiactions have to be made to adapt male connector. In the picture below you can see these modifications (view from below - looking INTO COPPER):
What other PICs?
Today it's not easy to get PIC16F877. Usually you can buy PIC16F877A which is not exactly the same circiut as it has different fuse bits. Configurations for fuse bits for PIC16F877A (tested by me) and PIC16F877 (untested) for Willem programmer are shown below:
Summing up, it's essential to set oscillator to High Speed
External Crystal, WatchDog OFF, Power-up timer ON (ON is
represented as zero).
Here are some photos of my tester (BC307 transistor was successfully used):
|Unfinished PCB||PIC programming socket in Willem PCB3, connected via ICSP pins.|| Finished tester in hand-made housing.
|A "Christmas tree" adapter for verifying tester's pins (on sheet with notes from implementing QtICTester).|
