In SX Microcontrollers, SX/B Compiler and SX-Key Tool, John B wrote: Have you installed the FTDI drivers? If not, go to [url=http://www.ftdi-chip.com]www.ftdi-chip.com[/url], download and install the Windows XP driver for the FT2332BM chip, and TEST it with a professionally designed FTDI USB Adapter. This will confirm that the driver was successfully installed and that your PC hardware is working as it should. If you have already done this, have you checked the oscillator for proper operation? Does the FTDI chip dynamically appear (graphically, of course) in your device manager window (under ports, com and lpt) when you connect it to the USB port? If you are still having trouble, please provide more information regarding how you determined it is not working and any other information that you can provide to give us a clue. In this case, a schematic and a photo of your prototype would be very helpful in identifying the trouble. ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=90573#m90602 Need assistance?
