Summary of GTP USB PIC PROGRAMMER
This project describes the GTP USB (non-plus, non-lite) PIC programmer by PICMASTERS, supporting PIC10F, 12F, 16C, 16F, 18F microcontrollers and 24Cxx EEPROMs. It includes schematic, photos, and PCB (ARES), requires WinPic800 v.355, and needs the PIC18F2550 to be pre-programmed with its hex using a classical programmer. Tested chips include PIC18F252/2455/2550/2520, PIC16F84/16F628, and 24C32 EEPROM.
Parts used in the GTP USB PIC PROGRAMMER:
- PIC18F2550 (bootloader/USB MCU)
- Various PIC microcontrollers for target devices (PIC10F, 12F, 16C, 16F, 18F series)
- 24Cxx EEPROM (example 24C32)
- USB connector
- Crystal or resonator for PIC18F2550 clock
- Voltage regulator
- Capacitors (decoupling and filtering)
- Resistors (pull-ups and current limiting)
- LED indicators
- IC sockets or headers for target PICs
- PCB designed in ARES
This work includes, GTP USB (not plus or lite) .
The schematic, photos and PCB have been developed by PICMASTERS based on
some valuable works done before. This programmer supports pic10F, 12F, 16C, 16F, 18F,24Cxx Eeprom.
Unfortunately, it works with only Winpic800 v.355.
We have succesfully tried it with some pics; PIC18F252, 18F2455, 18F2550,
18F2520, 16F84, 16F628 and 24C32 eeprom. The best and fastest method of pic programming.
All you need (hex file, winpic800, schematic, PCB board in ARES)
are included.
You must program pic18F2550 with hex file by a classical programmer.
Just leave a good fedback for us.circuit schematic. You can see the type and value of the companents.
