ADC CC2540!

Hi all,

I am using the Heartrate sensor project to get data from an external sensor. I only have one ouput from the sensor and I am assuming I need to use only one channel on the ADC instead of all 8. However the HalAdcRead () function in hal_adc.c is made to read from 8 and I was wondering how I could change this function to do this task. Also how/where do I call HalAdcInit function assuming I will fix this problem?

Thank you all in advance

HalAdcRead Is designed to read from single ADC input. Which Pin do you use as ADC input?

Hi Yikai,

I am using Pin 0_6 as ADC input.

Thank you.

You can use the following code to read ADC input from P0.6.
HalAdcRead(HAL_ADC_CHN_AIN6,HAL_ADC_RESOLUTION_10)

Thank you. Where do I call this function? Is it in the heartrate_Main.c ?

You can do it anywhere in your application.
