AnalogIn not functioning in Nucleo L053R8

Any code with the line: AnalogIn anything(A0); causes the system to hang. I can't use the analog inputs if I can not define them. Any ideas? Thanks, Jeff

Hi,

try to use PA_0 instead.

RGDS

Same result as A0, It compiles but does not execute, hangs.

Try using a terminal program to see if a"pinmap not found for peripheral" error comes up. This means you are using a pin for the wrong thing i.e. digital for analog or mixing up SPI pins. This error flummmoxed me for 3 days until I used A0 instead of PA_0 on a nucleo 401 board when I thought they were interchangeable. I realise you've tried both terms for the one pin, maybe you should try a completely different pin on another header.
Cheers

I use Nucleo L053R8,and have the same problem.When i try to use the PC_8,it will return "pinmap not found for peripheral" .But use any ADC pin to define: AnalogIn ain(ADC_PIN),the system will hang.
