RM48L952: On board temperature and light sensor pin connection

Rakesh Sharma1

Part Number: RM48L952

Hello,

I have seen in the RM48 Hercules Development Kit (HDK) User Guide that the RM48L952 has one temperature sensor and one light sensor, but am unable to find which ADC pin is connected to the sensors. I have to read the values from the sensors using I2C.

Thanks

Hello,

I figured out that the channel 8 and channel 9 of ADC1 is used for thermal (AIN8) sensor and light sensor (AIN9) on board. But still to receive the data from the sensors over I2C I have to send the slave address. What is the address for both the sensors?

Hello Rakesh,

The AD1IN[8] and AD1IN[9] are used for temperature sensor and light sensor. No I2C is required to read data from those two sensors.
