can anyone offer some explanation of the signal value required to control a GPIO pin as an output? Should it be 5:23 or 28:0 format?
I have the following to "tell" a control CPU when the sigmaDSP is ready and running it's program:
but the timer output goes low at power up and then high after 1 second, I want it to stay high and go low after one second, with a pull-up so the CPU isn't confused by a non-programmed DSP.
I tried everything I could think of to invert the timer output but all my attempts left the pin as a permanent low or a permanent high.
