Just out of curiosity, does anyone know how to send a command to the SPI display directly after initialization? It seems that the SPI bus is 'owned' by the displayio driver so i dont know how exactly to send a command directly to the display. Im wanting to turn off the display and turn it back on using the associated commands from the ST7735 datasheet. If i had initialized the display as a generic SPI device then it seems i could pull down the CS pin, write a command, and release the CS pin (after getting the lock on the bus). But the CS pin is defined as part of the ST7735 display 'driver' so not sure how to do that.

Thank you
