Discussion - EVE / Basic Arduino EVE Demo
« on: March 02, 2021, 11:37:08 PM »
We have released new sample code, this time for the Arduino UNO.

It is VERY basic code, mainly to get you started

This code will illustrate:
  • EVE initilization
  • Set colour
  • Draw blue dot
  • Write text
   
please note, this example does not utilize touch

Basic EVE Arduino UNO Example Code

Written for an EVE2 or EVE3 or EVE4 running on an Arduino UNO.

Code is located on GitHub
https://github.com/MatrixOrbital/Basic-EVE-Demo-Arduino

This code when executed will display MATRIX ORBITAL text and a blue circle.

Cyrilou,

I couldn't see what display you are using, but if you are using a Matrix Orbital EVE display you can use this module here to upload directly into the NOR Flash

The FIF0 is 4k so you might be over running the buffer. Make sure that your display list commands do not go over 4k

Simple weather station application for an ESP using the WEMOS D1 Mini and a Matrix Orbital EVE3 4.3" SPI Display.

The display used, EVE3-43G is an oversized Capacitive touch 4.3" IPS TFT for easy mounting and clean design. The EVE3 uses the BT815 and BT816 as the graphics engine and features 32Mb on-board memory.

Source Code
https://github.com/MatrixOrbital/ESP-EVE3-Weather-Demo





Requirements

    WEMOS D1 Mini (Most models of the ESP32/ESP8266 should work, but are untested)
    A Matrix Orbital EVE3-43 display
    A Matrix Orbital EVE2-SPI2BBC Breakout board
    A Matrix Orbital EVE2-USB2SPI-KIT-A USB to SPI Adapter board

Hello,

Thank you for posting on the forum.

If you please check out this sample demo code we have for the EVE's:

https://github.com/MatrixOrbital/Basic-EVE-Demo

You may check out the code and use it as reference.

This is a sample application written in C# for Windows that will allow bitmaps to be displayed directly onto a Matrix Orbital EVE2, EVE3 or EVE4 Series SPI Display. We also show off our new IPS 1000nit sunlight readable display!

Watch the video here



To use this application you will require

USB 2 SPI module or EVE3x USB version TFT Display

The sample application is written in C# with a DLL version of the Matrix Orbital Eve Library to handle the communication with the module.

riforifo,

We have done a few semi-custom displays for customers to harden displays against EMI/EMC/ESD. If you contact us we might be able to help you out.

Hi,

Thanks for those answers.

If you let me know what screen resolution you are using I can query the dev team for information on where the points would be located on the screen.

We are currently testing the 4.3" screen, with a resolution of 480x272. We will probably migrate to a 7" screen for a resolution of 800x480.

Hello T.Pierret,

Please contact me if we can help you with the hardware.

Thank you!

Since the inflate command can not know how much memory will be required to store the result of inflation, EVE writes back the last memory location used in a unconventional place.  In the "EVE School" example from Matrix Orbital, you can see this in action on the last line of the LoadJPG() function in "process.c".
