PLEASE HELP! Viewport Issues

albert

even though we have all the "right" equipment, downloaded FTDI from parallax.com etc. STILL does Viewport give us the same error "Failed to configure on COM13".

Can somebody just give me one simple explanation.



Sincerely Albert.

What Ports do you see in Device Manager?
You probably have wrong COM port number configured.

Hello, yes I'm using the right COM port. In device manager i can see 7, 8 and 13. But using the wrong COM port gives a totally different error message saying propeller not found (I just tried), which means that this is not the problem. It recognizes that there is a propeller connected to this port, but it can't configure it for some reason.

Do you already have a program on your Propeller?
If you have a serial port program running than it is probably blocking ViewPort. To make sure a program on the Propeller isn't causing this, open up Propeller Tool and type "PUB Start" into the blank editor. Click F11 (Load EEPROM) and then try Viewport. If the now-clear Propeller still doesn't work, you may try changing USB cables. I don't know how but when I had this problem that is what worked.

Hi Albert,
Here's another thread with several things to try:

Main issues:
- make sure you're using a good USB cable- not the retractable one that Parallax supplies
- start by using known good "Tutorial" programs

It doesn't matter what is in the Propeller's EEPROM, ViewPort will reset, load, run, and then establish communication with the program.
