QN908x: getting simple 16bit ADC result

Question asked by arpad.toth@scorpionauto.com on Aug 16, 2018

How to format the ADC result value to a simple unsigned 16bit preferably without float operation on QN908x?

 

Datasheet says:

The ADC result is 23-bit signed fractional data, with the MSB (bit 22) as the sign, while the output data to MCU is 32-bit.

ADC_OUTPUT[31:9]: ADC_DATA[22:0]

ADC_OUTPUT[8:0]: 0x00

 

I'm interested in 0-65535 range.

 

  rawADCval = ADC_GetConversionResult(ADC);
