Macros
Enums
ResetCause represents the reason the MCU was reset.
Functions
Convenience for setting up the dotstar LED using bitbang’ed SPI.
Convenience for setting up the labelled SDA, SCL pins to operate as an I2C master running at the specified frequency.
Returns the cause of the last reset.
Returns the serial number of the chip as an array of bytes. The serial number is only guaranteed to be unique if all 16 bytes are used.
Convenience for setting up the labelled SPI peripheral. This powers up SERCOM1 and configures it for use as an SPI Master in SPI Mode 0.
Returns the serial number of the chip as 4 32-bit integers. The serial number is only guaranteed to be unique if all 128 bits are used.
Convenience for setting up the labelled TX, RX pins to operate as a UART running at the specified frequency.
Attribute Macros
Attribute to declare the entry point of the program
