Progress Update

Community Edition: Pretty soon I’m going to have a very small update.  What that will do is check to see if the ESP32 can communicate with the Nextion 7″ display.  If it cannot, the BLUE LED will flash on the ESP32 until connectivity is established.

Pro Edition:
All of my development is happening on an esp32 on a breakout board. I should have some connectors here today and will move my dev code to the custom PCB. Once I get a few layouts done I’m going to be looking to send a few units out to Beta Testers. Beta Testers can get it with a case or without, up to you. But remember, how you mount it without a case is up to you. Please ensure you do not short circuit anything etc.

Pro Edition layouts: Here’s 3 that are in progress.  The first is the “Futuristic” layout which is currently being configured.  The next two are more retro layouts but I have not chosen which will be in the Pro Edition yet.

Progress update

Layout design is in progress for the Pro Edition. I’m looking to have some sort of demo of this layout. I have a new graphics guy in training so I’m getting him up to speed.

7″ and 10″ Display pictured with a in-progress layout design.  The layout in the image is the actual screenshot from the layout editor.  Layout may change slightly.

NexGenEFI Pro Edition PCBs are here!

The first run was made.  Had five (5) PCBs printed.  Now I need to upload my code and assemble one for testing. 

The first four (4) will be headed to beta testers.  I’ll install one in my turbo Camaro and test it in Production! LOL.

Even though they say 7″ Display board, its actually for both the 7″ and 10″ displays.

There is more fun stuff coming in.  Will post updates on how to apply to be a part of the Beta Testing Team in addition to more features which work with the Pro Edition!

Pro Edition Layout progress

Here’s a layout thats being designed.  Looks OK.  Still a work in progress and has more that needs to be done.

In general, there is alot left to do on the display side of the house since it will be different than the Community Edition.

Pro Edition PCB Status

The PCB for the Pro Edition has been sent off.  I have 5 being built.  I’m keeping one of the 5 for testing with 4 complete Pro Edition setups being sent out to testers.

There will be a process to APPLY to be a Tester.  Its a commitment and involves you being able to provide timely feedback.  Various qualifications will help as in social media reach, what you’ve tested before (other products), your skillset, your EFI setup.  More on that very soon.

As you see below, we’re pretty close.  The board is about 56% complete, then off to solder components.

Community Edition News

Bug Fix:
Leftover code caused an issue.  Reported by a user.  Version 1.01 is ready for Download on the Community Edition page.

Created a video so you can at least double check to make sure the ESP32 and Nextion display are communicating.  Located on the Community Edition page.

Wireless Data transmission

Testing out this Lilygo 2.1″ display to see how it would work sending real-time AFR data wirelessly from the Pro Edition development setup. It went well. I will NOT be using this in my Ecosystem, not because of lack of performance but capabilities and features that are not on the unit Lilygo sells.

Instead there is a custom PCB already designed for this type of work and various features it will support.


Sending data to two displays

Decided to play a little bit and threw together some code to send data to the Nextion display and wireless direct to the LCD.

Code not optimized so data gets to the round display first.

Testing different displays

One of the things I like looking at is what the market has out there for displays.  Not everything needs to be gigantic.  Small displays have a place in the auto industry.

Below is the Lilygo ESP32-S3 2.1 inch Round Display Touch Screen.  I threw on a resized RPM gauge from the Community Edition which is why it doesnt look sharp.  Then I had my wife make a png file of a transparent dial.  I wrote some code to make all this happen but havent written the code to “turn the dial” yet.  The gradient in the gauge is in the original image and hasnt been removed.

The second is another Lilygo display, a T4 v1.3 2.4″ LCD.  I had some fun with this one.  Created a starfield that is flying by with NexGenEFI bouncing around.  That was cool.
Both of these have a decent amount of horsepower and capabilities.  I’m not sure I’d use this in my lineup just yet as what I have will most likely require a custom PCB.  BUT I *CAN* do something with this.
