The MAX 10 NEEK has a Light-to-Digital Ambient Light Sensor (APDS-9301) that converts light
intensity to digital signal output capable of I2C interface. with I2C digital interface and
programmable-event interrupt output. The digital output of APDS-9301 will be input to the MAX
10 FPGA where illuminance I lux is derived using an empirical formula to approximate the
human-eye response.
Figure 3-35
shows the connection of APDS-9301 to the MAX 10 FPGA.
Table 3-17
lists the Ambient Light Sensor pin assignments.
Figure 3-31 hows the connections between the MAX 10 FPGA and Ambient Light Sensor
