Fermion: AS7341 11-Channel Visible Light Sensor

1. Example Code for Arduino-Data Reading

Read the values of 10 optical channels of the AS7341 spectral sensor, the more light of a certain wavelength of the light source, the greater the corresponding channel value.

2. Example Code for Arduino-Measure Light Source Flicker Frequency

Measure whether the flicker frequency of ambient light is 50Hz or 60Hz. Example Code 2.1 and code 2.2 can be used to simulate the flicker of ambient light at 50Hz or 60Hz.

3. Example Code for Arduino-Simulate 50Hz Light Flicker

Burn the codes to another main-controller, and connect an LED to the Digital pin 10 to simulate the light source of 50Hz.

4. Example Code for Arduino-SYNS Mode

In SYNS mode, it is necessary to give a falling edge signal to the sensor's GPIO to trigger the measurement.The chip will enter idle mode when the measurement is done, which could save power.

5. Example Code for Arduino-Simulate 60Hz Light Flicker

Burn the codes to another main-controller, and connect an LED to the Digital pin 10 to simulate the light source of 60Hz.
