I hope to use a acceleration sensor with nRF51822 dev kit. So I should use three ADC input. I tested getting one ADC data using adc_simple example(Keil_v5/ARM/Pack/NordicSemiconductor/nRF_Examples/11.0.0-2alpha/peripheral/adc_simple). But I don't know how to use multi ADC interrupt handler.
Hi
Please look at the ble_app_uart_adc_scan_mode example available on Nordic's Github page. Scan mode means that the ADC samples on multiple pins. There is some documentation provided when you click on the ble_app_uart_adc_scan_mode folder. Specifically look at how multiple inputs are configured in the adc_config function and how samples are handled in the adc_event_handler callback function.
Thank you for answering me. I downloaded and tried it but I got errors like below.

I located the example folder at "C:\Keil_v5\ARM\Pack\NordicSemiconductor\nRF_Examples\11.0.0-2.alpha\ble_peripheral\ble_app_uart_adc_scan_mode".
And actually I hope to test multi ADC(for acceleration sensor) based with "C:\Keil_v5\ARM\Pack\NordicSemiconductor\nRF_Examples\11.0.0-2.alpha\peripheral\adc_simple" this sample, if it is possible.
I only installed NodrdicSemiconductor::nRF_DeviceFamilyPack, NodrdicSemiconductor::nRF_Drivers, NodrdicSemiconductor::nRF_Examples, NodrdicSemiconductor::nRF_Libraries packs after install Keil uVision5
Well, I removed and add again Drivers and Libraries, and modified project option-C/C++-Include Paths. I still have some errors and be fixing it.
Hi
The example is meant for SDK 11.0.0, but I can see you use SDK 11.0.0-2.alpha. Try it out using SDK 11.0.0
