I recently misdiagnosed a "maybe-uninitialized" diagnostic as a bug in asf4. However, the problem was in our SPI code. A special case for samr21 MCUs was being applied to same54p20a and possibly other D5x/E5x MCUs, since the check was simply for pin PC19 existing at all. Change the check to use the macro PIN_PC19F_SERCOM4_PAD0 which is only defined if special function F of pin PC19 is SERCOM4 PAD0. Reorganize the code a little bit so that brace-matching in editors is not confused by the conditionalized code, including an unrelated change for APA102_SCK's condition. Revert the change to the Makefile that incorrectly attempted to silence the diagnostic. |
