Hello,

i have the problem that all GPIOs are default set to input, when you connect the SUB-20 to a PC.

Is it possible, that all GPIOs are configured as output as default and the value is configured to 0 at every GPIO as default, when I connect the SUB-20 to a PC?

Hello,

I would like to send, e.g. the hex "E201" about the GPIO Header Pins: 2,4,6,8,10,12,14 and 16 (direct GPIOs: 9,11,13,15,25,27,29,31).

How must I program in C using the library from SUB-20?

Could you help me please?

What exactly means "SUB-20", because I will have to explain this namely in the diploma thesis...
