Cannot read any values from analogIn pins

Questions » Cannot read any values from analogIn pins

I have written a simple little program to print out the float value from any analog input like this:

AnalogIn pot(PA_1);

and in the main inside a while(1) i print pot.read() to tera term

but i only get values like 0.000488 and no matter how much i turn the pot meter it doesnt change.

the program and connection works perfectly with the LPC1768 but it won't work with the L476VG

If you import this example and don't update the Mbed library it will work, just tried. Stopped working when I updated Mbed Libraries.

I would suggest you report this as a bug.

Just checked, works fine on Mbed OS5
