Concept for displaying LINK ECU data via CAN using an LCD display: DIY LCD display

Background

I tried receiving CAN signals, converting them to serial data, and operating a Defi meter.

Mechanical meters are good for intuitively seeing values like boost, but digital meters are fine for things like water temperature and oil temperature.

Problem Statement

I could use a Defi digital meter, but they aren't really available used, and they are expensive (´・ω・｀)
In that case, wouldn't it be faster to just make one!?
The image is a DIY version of the MFD32 in the title image.

Direct LCD display

It's just receiving CAN data from the ECU with a microcontroller and displaying the values on an LCD.

I will display the signals that were going to the Defi meter directly on the LCD

Parts used

ESP32

LCD display

MCP2515 CAN BUS Module
If you buy Chinese-made ones on Amazon, they might be broken or have defects, so I recommend buying proper ones (´・ω・｀)

Result

I was able to display the values read from CAN on the LCD display.

Summary

I was able to display the LINK ECU GENERIC DASH CAN signal using an LCD display.

Parting shot

If I use CAN signals to display data on a large 7-inch LCD screen, it seems like it could serve as a replacement for a DASH display.

Next concept

A DIY GPS logger.
I am planning to build a device that synchronously measures CAN signals, GPS, acceleration, and gyro signals to display lap times and perform logging.
