[MatthewJeffson]

Overview

• We need your help to build a car OBD with XIAO ESP32C3 and XIAO CAN Bus Expansion Board and write a wiki regarding it.
• reference:

• Template for wiki contents

How do we work together?

• Leave a comment with your GitHub name below as you accept this assignment and will complete the contents about what we are trying to present.
• The maintainer will assign and record you as our only contact for this assignment.

Hi @MatthewJeffson,

I recently discovered Seed's contributor program and am eager to contribute. With almost 2 years of professional experience, I specialize in building libraries for microcontrollers such as ESP32 (ESP-IDF), STM32, Atmega Series, etc.

I'm keen to connect and actively participate in Seed's program. Please feel free to reach out to me at roypriyanshu09@gmail.com.

Best regards,
Priyanshu

@Priyanshu0901 Hello Priyanshu!
Sorry the late response! I have emailed you:D

@thealexproctor Hello Alex! How is it going with the project. I have been informed that another contributor is interested to do it.:D
Best Regards,

Working well, was taking a little while as I was waiting for some more ESP32C3 boards as they were on backorder, but getting design more finalised.

Also Custom PCB's @MatthewJeffson

[MatthewJeffson]

@thealexproctor WOW! Alex! That was amazing!

[thealexproctor]

Thanks @MatthewJeffson, I am really trying to finalise the design and get it working perfectly to make it as easy as possible to produce more, ive taken the assembily time down from 1.5hrs to about 30 minutes per gauge with the custom PCB.

Could you tell me @MatthewJeffson do these displays support reading from the display? as im trying to get the TFT_espi Animated Dial example to work, but it seems to have a issue, perhaps you could clarify.

Could you also clarify if the display supports backlight control? as I can see BL is on Pin 6 so was hoping I could send a PWM signal on Pin 6 to control the backlight but this does not seem to work.

[MatthewJeffson]

Hello! @thealexproctor Alex! Reducing time to assemble is looking very promising!
Regarding the TFT_espi and backlight control, I will contact my colleagues to see if there is anything that we can help with:)
Really nice work!The design is truly impressed!
As we updated the ODM service, we will contact the related colleagues as well to see how the progress is going.
Best Regards,
Matthew

Hi @MatthewJeffson how did you go regarding finding out about the display? Would love to deep dive into some extra functionality.

[MatthewJeffson]

Hello @thealexproctor Alex! I am so sorry for long time not reply. Things been crazy lately.XD

1. The backlight control only supports "on" and "off" and can not be controlled by PWM.
2. And for the "TFT_espi Animated Dial" example, my colleague has tested it and it seems ETA3410 not supporting pixel reading function.

We have set up a discord channel and would you mind joining us? for the instant communication?
Best Regards,
Matthew

Sure, can you email me a link? I might already be in it

[MatthewJeffson]

Hey lo! I have sent you the link @thealexproctor :D
