It is connected to serial port of your PC and it has a very similar design with the SI-Prog programmer for the AVR microcontrollers. Perhaps this circuit is the simplest programmer for PIC microcontrollers you can build. The post True USB GQ-4X Programmer using pic microcontroller appeared first on PIC Microcontroller.

How to wire up a suitable serial connection for the PC: With a male to femail DB9 serial connector, just wire pin 1 to pin 1, 2 to 2, etc… Do NOT use a “Null modem cable” Since this will swap pin 2 with 3 etc… and cause the RS232 drivers on the Pocket to possibly burn out.įor more detail: True USB GQ-4X ProgrammerĬurrent Project / Post can also be found using: Read through it to discover how to set up and calibrate the programmer and then how to use it.

Turn off the power, download the software from or, run pocket.exe from your installation directory and open the help file. Please go over you work again and make sure that 5 volts appears on the correct power pins on each chip. If the display has not responded with that message then you have done something wrong. When turned on without operational data available, the Pocket will display this message. The LCD is probably still blank, so turn the contrast pot away from the RS232 socket to make the display visible. If you are satisfied that all is well, apply power and switch it on. ZIF socket 40 pins or 4 pcs 1x20pin female row socketsĪssemble the unit by matching the parts to the parts list above and then inserting them into the space for each part as labeled on the PCB. 1x4pin male connector to LCD pins 12-14 DO NOT USE A NULL MODEM CABLE TO CONNECT THE POCKET TO YOUR PC! The correct connector wiring is straight through: Pin 1 to pin 1 etc… Component Read through the help to discover how to set up and calibrate the programmer and then how to use it. , run the setup program, edit pocket.dat so that it contains the number of the com port you will useĪnd run pocket.exe from your installation directory. Turn off the power, download pocket.zip from Just do a complete check of the parts for correct orientation and give the PCB another look over and check for possible shorts and joints that have not been soldered before you apply power and switch it on. The PIC16F876 comes pre-programmed so the unit is ready to go when you power it on. Pin one is clearly marked on the silkscreen for all polarized components.
The boards are excellent! has done their normal great job! The clear silkscreen and parts list (see below) makes assembly a snap. (we are looking for a good, low cost, ZIF socket… please let us know if you know of one).
With Tony’s blessing,, in cooperation with, is producing a new kit with an easy to assemble board (no SMT, with solder mask and component silkscreen) and all parts (except the ZIF socket) for $70. The biggest problem was that the board did not have a solder mask or component placement silkscreen.Īndrew Sorriaux sent some pictures of his version.

The assembly instructions in pdf format (cached 20010523135942) and CSS HTML 20010904105856 and everything else is installed by the Win32 specific install program in the download. The original kit did have a few SMT components, but the pads were oversized and so it is not as hard as you might think.
