GPIO on DSP?
-
Hello, in the documentation for the VOXL 2 connector J19 pin 9 is listed as a GPIO, the other pins are connected to the SLPI/DSP, is the GPIO connected to the DSP as well? How can it be controlled from within the DSP? Are there any other pins that can be used as GPIO and controlled from the DSP/PX4? Thank you

Hi @czarsimon
J10 pin 9 is a Voltage for Spektrum Style RC modules that require a power ON/OFF/ON sequence to bind.
GPIO_159 is the GPIO that enables this feature. If held static ON, this is a reverse protected 3.3V pin, up to 1A of support.
All Board-to-Cable (JST's) connectors are on the DSP since they are purpose designed for Flight Control features.
You'll need to use the Board-to-Board connectors (J3 and J5) for Apps GPIOs.https://docs.modalai.com/voxl2-connectors/#j3---legacy-board-to-board-connector-b2b

Hope this helps!
