Designing SECC for DC Charging with QCA7000/7005

[forecast]

Hi,

I want to design Supply Equipment Communication Controller (SECC) without Linux, I want to use cheap microcontrollers (STM32 or another MCUs)
I already started design with STM32 but I don't know how to build software based on QCA7005
Does anyone have any information on this subject or can help?

Thanks

I guess you want to look at the Foccci project. It is the EV side, but the hardware is near identical on both sides. Only you need to generate CP PWM, not read it.

Also software will share a lot of code.

When using Foccci knowledge please make your project open source as well

Thank you for answer.
Yes, I have seen this post before, I already generate CP PWM and I’m considered about software, because I haven’t worked with PLC before.

I will use this project for only communication controller by the way

Hello,

I was also thinking on working on a similar project, maybe we can try to collaborate on this using Foccci as a reference? Feel free to dm me so we can discuss further.

Thanks.

Okay, sounds good.

A starting point (actually perhaps already a solution) for the EVSE side is mentioned here: https://github.com/SmartEVSE/SmartEVSE- ... 2271141043
