DotStar w/ Shield Shield Not Working

Troubleshooting

I agree with @bko (since he answered while I typed this up :wink: ), but another short term solution is to change these macros like this

STM32_Pin_Info* PIN_MAP2 = HAL_Pin_Map();

#define pinLO(_pin) (PIN_MAP2[_pin].gpio_peripheral->BSRRH = PIN_MAP2[_pin].gpio_pin)
#define pinHI(_pin) (PIN_MAP2[_pin].gpio_peripheral->BSRRL = PIN_MAP2[_pin].gpio_pin)
#define pinSet(_pin, _hilo) (_hilo ? pinHI(_pin) : pinLO(_pin))

But these will be superceded soon by new functions pinResetFast(), pinSetFast() and digitalWriteFast().
