Hi everyone

I have a question regarding the time difference between two acquisitions.

1) when I use wiced_hal_adc_read_voltage I can measure a time difference of ~150 us between two readings.

2)yet when I use wiced_hal_adc_read_raw_sample I measure around ~150 us as well.

shouldn't the latter take less time (around 50 us)?

Thank you for your answer

Regards

Ardo

Hi Ardo,

Both the functions you mentioned do averaging of samples, which results in similar time difference between readings. Therefore you are getting difference around 150us in both the cases.
