What is the purpose of RCIO_PC10 and RCIO_PC11 pins on Navio 2. I know these are connected to STM32 but for what?
As for RCIO_SWD_IO and SCIO_SWD_CLK pins I read somewhere these can be used to flash and debug STM32.
For, RCIO_SPI_ I suppose this interface is used for PWM channels to be expanded by STM32?
Being a developer, it becomes very difficult to work with such boards with insufficient information!
