Hello everyone, I installed the Propeller Proto Board on my hex robot.

I encountered a problem about the power supply. I tried to compile my program into EEPROM, then I think that I just need to open the power switch, that the chip will be work, but it didn't

My power supply is 9V DC, but when I remove the USB cable which connect my computer and the Propeller Proto Board, then the chip didn't work normally.

Whether I must to connect my computer with the Propeller Proto Board, then the chip will work?

In other words, is it means that I must use the USB + Power supply, and the chip will be work successfully?

How to solve the problem? Are there any suggestion?

thanks

    If you have a serial debug to the terminal via USB, and you disconnect the usb cable then the prop hangs. It is a known issue.
    It this is your case you can load a dummy object (OBC posted a parallax serial dummy in the past), or disable the debug.
    If this is not the case there is something else, and more informations are necessary.
