I have the Melabs USB programmer and I am trying to program a
PIC18F4550-I/P
I keep getting the error target device does not match selected device. I have the PIC18F4550 selected from the full down menu. I am not sure if the -I/P makes a difference? I checked the troubleshooting section on the melabs site. They said just to make sure I had the right chip selected...I do, check the power in the board for 5V, I did, and I am getting 5 volts. And to make sure the chip is seated right, I think it is, doesn't look like I can screw that up too much.
This is the first PIC I have ever tried to program. I an new to PICs but not electronics or programming.
I have several PIC18F4550 and 18F4450 and have gotton the same error with each.
Anyone know what may be going on? Does the Melabs programmer use a special USB cable? I am using a USB cable that I baught for my printer, but is is just a basic USB 2 cable.
Any help will be appreciated.
thanks,
mw
