Moving up from Arduino - have been LONG time fan of the ARM world. Now digging into the HAL functions for an STM32 board/chip. Have also been BLOWN AWAY by the specs of the Teensy 4.0! Have no use other than to just "have one that fast" and to tinker with it. With my ongoing exploration of the ARM/HAL world wondering if I can access the peripherals on the processor.
