Porting the I2C Slave code from AT11628 from the xplained board to the user-board, trying to circumvent some xplained confusion with CTRLA.SPEED and CTRLA.SCLSM
Imported defines from SAMD20 xplained board specific to the MCU -> user_board.h (src->ASF->common2->boards->user_board) Imported inits from SAMD20 xplained board specific to the MCU -> init.c Added GPIO via ASF wizard Added test code: SW0 = LED0 state Validated. Base SAMD20J18 MCU code with GPIO initialized.
