Some of the applications mentioned by the datasheet:
- Altimeters and barometers for portable devices
- GPS applications
- Weather station equipment
- Sport watches
Important: make sure you properly setup the I2C pins especially for ESP32 before creating the I2cDevice, make sure you install the nanoFramework.Hardware.ESP32 nuget:
//////////////////////////////////////////////////////////////////////
// when connecting to an ESP32 device, need to configure the I2C GPIOs
// used for the bus
Configuration.SetPinFunction(21, DeviceFunction.I2C1_DATA);
Configuration.SetPinFunction(22, DeviceFunction.I2C1_CLOCK);For other devices like STM32, please make sure you're using the preset pins for the I2C bus you want to use.
