Fermion: TMF8801 ToF Distance Ranging Sensor (20-2500mm)

1. Example Code for Arduino-Distance Detection

Get measurement data by PROXIMITY and DISTANCE hybrid mode. note: TMF8801 only suport one mode, PROXIMITY and DISTANCE hybrid mode.

2. Example Code for Arduino-Calibration Mode

This demo tells how to get 14 bytes calibration, and how to set calibration ranging. This demo application scenario: no target within 40cm of the sensor, in dark conditions.

3. Example Code for Arduino-Sleep Mode

The sensor sleeps for 2s when finishing 20 measurements. In sleep mode, it stops ranging. We can activate it by wakeup function. Note：it consumes 37.9mA current in ranging mode, 1.2mA in sleep mode.

4. Example Code for Arduino-Interrupt Output

If you enable INT pin, MCU will capture a interrupt signal when the measure is completed. You can attach the INT pin of TMF8x01 to MCU external interrupt pin. When there is data output from the sensor, the INT will generate a LOW level and MCU can determine the coming data by detect that low level.
