Photon 2 : Battery : CHG and A6 Pin error on compilation

Hardware
1

Hello,

I am trying to get battery information like explained in the documentation but i get error on compilation :

void setup() {
// Put initialization like pinMode and begin functions here.
pinMode(CHG, INPUT);
}

void loop()
{
// The core of your code will likely live here.
bool ChargingState = digitalRead(CHG);
float voltBat = analogRead(A6) / 819.2;
}

Errors :
'CHG' was not declared in this scope
'A6' was not declared in this scope; did you mean 'A3'?

What am i missing ?

Thanks in advance.

Best regards.

Which build environment are you using?

WebIDE: Make sure there's a gold star before the Photon 2 device in the Device tab

Workbench: Use Particle: Configure Project for Device and make sure you've selected P2 as the device type.

I use the WebIDE and my photon 2 is selected (Gold star in front on it).

Device OS Target : Default (3.2.1-p2.3)
On the device: 5.1.0

I get this error on compilation log :

Select a newer version of Device OS in the target popup. 5.4.1 is recommended.

3.2.1-p2.1 did not have support for CHG or A6.

That's it !

Thanks a lot.

Best regards.
