| Since my pic programmer died (see the dual
power supply project page), I came up with a solution using a Digilent
JTAG3 cable (which I had on hand). After figuring out how to make it
work, I left the information posted on my website, but didn't actually
build a device which would allow me to easily program pic devices. A
few days ago, I decided to put it together and now I have a very easy to
use solution for programming pic devices. Here are some pictures of
the programmer.
The complete schematic is shown below. This is exactly what I built. The LED's are helpful in troubleshooting a problem. They also allow you to determine when the device is being programmed, and when it is finished.
TO USE THIS PROGRAMMER!-> please visit my JTAG3 Pic Programmer page for complete instructions on how to use this device. The recommended program and the JTAG3.INI file for operation are there. |
