NVM Software Calibration Area Mapping
Configuring the system clock sources.
You will typically need to create an instance of
ItsyBitsy M0 pins
Import the prelude to gain convenient access to helper traits
Configure the SERCOM peripherals
Delays with WFI sleep while we wait using a timer
Working with timer counter hardware
helper struct to calculate divider & cycles settings for timers.
ResetCause represents the reason the MCU was reset.
Convenience for accessing the on-board SPI Flash device. This powers up SERCOM5 and configures it for use as an SPI Master.
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 externally labelled SPI.
This powers up SERCOM4 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 RX, TX pins to operate as a UART device running at the specified baud.
Attribute to declare the entry point of the program
