So I recommend use a Desktop Computer which comes with an inbuilt DB9 Serial port. DonвЂ™t even think about USB to DB9 converter, it just wonвЂ™t work. Usually now a days laptop's does not comes with a DB9 serial port, so if you are thinking to use a USB to DB9 converter cable for doing this job then its a bad idea. I recommend do not use a laptop for JDM programmer. This JDM programmer uses RS232 DB9 port to program the code into the microcontroller. As of now with this JDM programmer we are going to program PIC18F4550 USB Interface Board for FIRST TIME BURNING OF CODE INTO THE CHIP Later for a better programmer I recommended pickit3 from microchip which makes it easier to program with a USB port. So itвЂ™s a good option for beginners to stay with JDM programmer as cheap alternative in the early stages. It works with lot of other hardware too, which are similar to JDM programmer, like the but it costs around 60 в‚¬ from their official website. Winpic800 is compatible with pic18f4550 and JDM serial programmer. There are many knowledgable engineers on that list.This jdm programmer responds, or lets us to burn the program into the microcontroller chip through small software known as winpic800. You might also try joing the piclist ( ). IвЂ™ve heard that LVP is pretty finicky and not too reliable, so IвЂ™ve always stuck with regular ICSP.

Microchip has Application Notes on how to do this. It will be up to you to generate the LVP programming commands on this controller. You would wire the serial output from this to the microcontroller on your programmer. I belive you could use the converter schematic I pointed to for part of your design. If so, I couldnвЂ™t find a schematic that specifically covered LVP ( low voltage programming ). It will then send the LVP control signals to the chip that you wish to program. This onboard controller will read in the Hex file.

The converted RS2332 signal will be passed to an onboard microcontroller.

The programmer will have an onboard USB to serial converter like an FTDI. You will adjust the PC to send the RS232 signal from the programming software over USB to the programmer. The PC programming software is set up to send the Hex file via PS232. It will have an output plug that will program the Pics with Low Voltage Programming ( as opposed to the normal ICSP style ). This programmer will have a USB plug to connect to a PC. You want to build a circuit to program Pic microcontrollers. I wonder if I understand what you are looking for? This is what I understand:

Sparkfun includes a datasheet and driver downloads, though. IвЂ™m not sure what it takes under Windows or Mac. It wasnвЂ™t too hard once I knew what to do. I needed to add a rule in /etc/udev/rules.d. With the USB to serial converter, I had to do some work to get it to work under Linux. I see that Mouser now sells it for USD $34.99 here: It might with MPLabX, but I havenвЂ™t checked. I havenвЂ™t upgraded to the PicKit III yet because IвЂ™m not sure if it will work under Linux. It is USB and connects to the ICSP pins of the Pics ( MCLR, Vcc, Gnd, PGD, and PGC ). I eventually bought Pics that it couldnвЂ™t program with the PicStart+ under Linux ( with picp ), so I bought a PicKit II from Mouser for about USD $30.00. I bought something like this ( В ) from Sparkfun. When I moved to laptops, I suddenly lost my serial port. I used a PicStart+ for quite a while when I started with Pics.
