I'm using the DAC+DSP board + DAC add-on to create an active crossover for my stereo system.
I would like to use the signal detection block in sigmastudio to send a message back to the pi so it can power on external amplifiers. I've tried wiring the signal detect block to a register write block (writing to an unused register) and then reading that register -- it didn't work.
Reading the Sigmastudio documentation it seems like a gpio command is the normal way to operate. I see in sigmatcp.py that a function gpio_request and readwrite_gpio exist but without any documentation that I could find.
Can I get help on how I might implement gpio communication between a sigmastudio program the pi through sigmatcp?
