It apparantly has no AnalogOut. Regarding AnalogIn, are you using it for pins which are listed as AnalogIn pins on the pinout picture?

Accepted Answer

Hi,

i'm using nrf51 dongle and i'm not sure it there is Analong In ... where can I found this ?

on the nrf51822 page (https://www.nordicsemi.com/eng/Products/Bluetooth-Smart-Bluetooth-low-energy/nRF51822#sthash.7M6XwwAc.dpuf) there is Configurable I/O mapping for analog and digital I/O

edit : I found the answer on the doc, there is just digital pin on nrf51 dongle.

Hello! The link above bring us to a general information. Where can we find the name or the mapping related to AnalogIn? I mean, how is this? "AnalogIn analog_value(P0_6);" Is P0_6 a valid definition?

I am using it but get a value of 0 when reading the port. example: level = analog_value.read(); This does not return any value.

............

Sorry I found my mistake. The returned value is float and I used int. Anyway the above comment about the analog port definition seems to be correct.
