DIY Programmer
This programmer connects to a PC serial port. It is inexpensive to make. Alternatively the end of the article has links to ready built programmers.
- powered from target system 5V
- Uses +12V programming
- Many devices not just PIC
- NO support circuit or bootloader needed on target hardware
- Built in -5V and +12V switched capacitor power supply runs off Target +5V
- No need for multiple expensive ZIP or damage to CPU removing from target.
- Even solder in the PIC cpu on target hardware.
- Just six pins

RS232 Functions
| Signal | 9p | 25P | function |
| TXD | 3 | 2 | 12V Vpp on/off |
| DTR | 4 | 20 | Data In to Device |
| RTS | 7 | 4 | Clock to Device |
| CTS | 8 | 5 | Data from Device |
| GND | 5 | 7 | Signal Ground |
DEVICE PINS
6: 5 V supply from Device
5: +12V Vpp switched out (PIC MCLR) Should have diode rather than resistor to 5V on target
4: OV / Ground
3: LVP disable for 16F87x type PICs
2: Data I/O Bidirectional
1: Clock to device
