Two questions regarding using the Raspberry Pi Radio Module 2 with the cygw43 driver in the Pico SDK. Does the driver support gSPI data in, gSPI data out and nIRQ being connected to three different GPIOs rather than to a single GPIO through resistor strength logic as documented in the datasheet?I.e. can I do this?I don't want it to be full duplex, just to make it play nice with other SPI devices hanging off the same SPI bus.
Second question. Does the driver have any provision for there being additional SPI device(s) hanging off the same bus? For example, is there a way to temporarily disable related interrupts so that they do not interfere with communication with other SPI devices on the same bus?
Thanks!
