Hi , I am trying to add a radio module ( si446x ) to teensy 4.,1 while also using audio adapter rev D.
pins , 10,11,12,13 appear to be used by the audio adapter for SPI SD card ( I think its shared with the SD card on the teensy 4.1 )
Can I safely use SPI1 instead of SPI0 for my RF board ?
pins 0,1,26,27 pins 0,1 are also RX1 RX2 a UART ? on the schematic AD_BO_2 and AD_BO_3 are what ?
does anyone have a PDF schematic of the teensy 4.1 ? or something other than the picture on the website , I find that really hard to read / search for pin connections.
any help / advise / pitfalls of using SPI1 would be much appreciated.
