Tle5012Ino

class Tle5012Ino

represents a basic TLE5012b Arduino class.

represents the TLE5012 base class This file is only a startup wrapper for Arduino IDE so that the framework setup can be handeld without any special setup.

represents the TLE5012 base class

This class provides a simple API for connecting Arduino/Genuio and compatible MCUs. As the default interface for the sensor is the 3wire SSC SPI interface, the default SPIClass is extended by the SPIclass3W.

Tle5012

This class provides a simple API for connecting the TLE5012 via SSC interface, which is included into all flavours the TLE5012 sensor. This setup also works with the Sens2Kit (Sensor including XMC1100 mcu), breakout board (only the Sensor from the Sens2Kit) and bulk chip (read the section on how to connect the bulk chip via 3wire SPI).
