Hi All,
In my application I have two analog inputs coming from two different sources that I have to sample using one SAADC present inside NRF52. As far as I know, NRF52...
Hi,
I'm using nRF5 SDK V12.0, I found a strange problem. That is the UART can send data to PC, but it cann't receive data from PC. However, this problem just arise on some...
Hi,
I need a bit of help to fully understand how ADC works on nRF52832.
I am using a Thermistor sensor like the following to measure temperature:
