Enums
ResetCause represents the reason the MCU was reset.
Functions
UART is connected to the ESP32 Wi-Fi co-processor
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.
This powers up SERCOM2 and configures it for use as an
SPI Master in SPI Mode 0.
Unlike the flash_spi_master
function, this
one does not accept a CS pin; configuring a pin for CS
is the responsibility of the caller, because it could be
any OutputPin, or even a pulled up line on the slave.
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.
