SDK Version 1.0.17
USBizi V 220.127.116.11
I have searched but I did not find a topic similar to this one. My appologies if one does already exist.
I have a simple program in C# which makes UART communication possible over COM 1 on FEZ Panda II board. The problem is, that the program only seems to run with the USB cable attached.
Whenever I unplug the cable, the program stops running. Even without visual studio running, so no active debugging from VS2010.
Scenarios I tried that did not work (red led was burning):
- 7,4 volt power to Vin, without USB + reset
- 12 volt in via adapter, without USB + reset
- MOD jumper to GND, serial debugging works, but only when USB cable plugged in.
- USB cable plugged in, external power supply (7.4 v battery or 12 volt adapter), removing (test serial connection, works) now removing the USB, no serial connection anymore.
I only get serial response (or servo movement for that matter) when I use the USB cable.
What am I doing wrong? Am I missing something trivial here?
Thanks for helping in advance.
