Pin change RelayAC

[DeltaVetal26]

Hi, lincomatic! I need to change pin relayAC from digital to analog. In open_evse.h I found the lines:

`#define CHARGINGAC_REG & PINB

define CHARGINGAC_IDX 1`

Everything was fine, if I used a digital pin for the relay, but I only have an analog one. Any ideas? In J1772EvseController.cpp, I found the code responsible for setting the relay pin:

`#ifdef CHARGINGAC_REG   pinChargingAC.init (CHARGINGAC_REG, CHARGINGAC_IDX, DigitalPin :: OUT);

endif`

It's unclear how to change the pin from digital to analog. Any ideas? I apologize for diverting stupid questions.

In the void setup (open_evse.ino), I added:

pinMode(A6, OUTPUT);

Further in J1772EvseController.cpp I'm under each pinChargingAC.write (1); make

digitalWrite (A6, HIGH);

And LOW, when charging stops. It is safe?

Sorry for taking so long to get back to you.. been out of town. Which MCU are you using m328P? is it an OpenEVSE board or Arduino? I can't tell you what to do unless I know what hardware you're using.

I use arduino m328p board. Simply, the relay contact is connected to the analog contact, and not to the digital one, to which the relay was connected in the usual OpenEVSE. I did, as I wrote in the previous post, the system works fine, the relay turns on when charging starts and turns off at the end. But I was not sure of the correctness of this decision.

The way you are doing it will work OK, however, the correct way is to simply change the definition in open_evse.h. Which Arduino board are you using? The ones I use only have A0-A5, no A6. As an example, let's use a Duemilanove board.

A5 = PC5

so all you need to do is change

define CHARGINGAC_REG &PINC

define CHARGINGAC_IDX 5

@lincomatic It works! Thank you very much!
