Maple core: to use SPI2 for SPI. edit SPI.cpp for SPIClass SPI(2);
STM Core: to use SPI2 for SPI. edit variant.h to use PB12-PB15 for SPI_SS etc
STM Core: to use SPI2 for SPI. edit variant.h to use PA15, PB3, PB4, PB5 for SPI_SS etc
Touchscreen needs XM, YP to be on Analog capable pins. Measure resistance with DMM to determine X, Y
300R pair is XP, XM. 500R pair is YP, YM. choose XM, YP from PA7, PA6. XP, YM from PB6, PB7
