Longan Nano BME280 SPI Example

This is the result of me trying to understand longan nano spi used with a sensor.

Topics

It contains various examples that should be reusable in other code

  • Serial output with printf()
  • Using RGB LED of Longan Nano
  • Read onchip temperature and reference voltage
  • Init SPI
  • Use BME280 sensor driver from Bosch with SPI
  • Use 160x80 OLED SPI LCD
