Using an isolated RS485 board without TALK PIN

[Sleeper85]

Hi @txubelaxu

Could we use another RS485 board as I propose in my README and have the option of not having to define a GPIO for the TALK PIN ?

This is the RS485 board (high speed dual) used with the PVbrain2 PCB.

All the GPIOs of the ESP32-S3 are already used for different functions and distributed on the PCB.
So I would like to be able to not have to define the TALK PIN.

Thanks for your help and development of this component.

I'll try to change the code to "optional" talk_pin

Hi @Sleeper85,

I have just change that setting to OPTIONAL, so you should remove from yaml, because it is not mandatory now.

Could you test, please? Tell me, please, if you find any problem.

Thanks!!!

Thanks, I confirm that I can compile this new code without problems but I cannot test it personally because I don't have a JK-PB BMS.

@txubelaxu would you be interested in testing it yourself ?

Otherwise, is ( @widget4145 / @cinusik / @virus100b ) willing to test this RS485 board ?

The goal is to be able to confirm that this RS485 board (without talk pin) works well.
It is a very good isolated RS485 board and I would like to be able to recommend it.

RS485 isolated board (choose this version => high speed dual)

Yes, Iam compiling esp-jk-bms-can now and I will test it. El El dom, 4 ago 2024 a las 19:28, Sleeper85 ***@***.***> escribió:

@Sleeper85 As soon as I will have some time will test it with the RS485 Atomic board from M5, as I don't have one mentioned but it should also work. Let you guys know once tested.

I've got a different board without a talk pin as well that I'll hopefully be testing soon. I'm compiling now.
