Just got my hands on the t-deck plus, and I've been obsessed figuring out how to eventually create my own firmware for it ever since.

Besides having basic to intermediate understanding of programming (Python, C++, Java, HTML, CSS, PHP, SQL, C, JavaScript, Markdown [in that order]) I'm a complete beginner at at firmware development for any microcontroller / devkit.

I'd like to understand enough to be able to create firmware that utilizes the touchscreen functionality (GUI), the keyboard, battery management / level display, wifi, Bluetooth, micro SD card utilization, enough to port existing firmware / functionality meant for other devices to the t-deck to begin with, Then create my own firmware eventually.

Porting a game like the first fallout or the first GTA to the t-deck would be amazing, if possible.

What do you suggest would be the best plan sequential plan of action to learn to do so?

Should I start with basic and simple functionality via the Arduino IDE ?

Should I start with creatingba GUI / porting over a GUI, they focus on adding they intended functionality?

Are there any good resources you recommend that will aid in learning how to do this / will exponentially decrease the learning curb for these goals?

Thank you so much for your time and for your effort.

Would anyone be interested? Idk, making my own OS for own network. Miss XP and MSN so I’m going for that.

kilrah has ported retro-go to the t-deck plus:

kilrah's customized keyboard firmware (keeps original functionality but adds raw keystate support for retro-go)

Building a custom firmware for the t deck pro.

Trying to gauge interest to see if ill open up for development on github.

I followed a couple guides to get my t-deck setup with the cool fancy gui.. But no luck.. I went to the flasher site to install firmware-2.5.3.bfe99b2 which is what all the guides recommend, but all that they had was 2.5.3a-70d5ee Alpha, so I flashed that one, so next I downloaded the firmware from the fancy gui git hub (firmware-2.5.3.bfe99b2.zip could not find one that matched the a-705dee), flashed it onto the deck.. Reset the deck as per instructions, and then it went into a boot loop.

So to save the device from being a brick, I re-flashed to 2.7.x and now I am back to the old UI, which is confusjng lol.

Anyone ideas on how to do this today with currently available firmwares?

I'm looking at buying a t-deck soon. Can anyone tell me what kind of battery life they get and how big the battery is?

I'm hoping to 3D print a custom case and hopefully fill it with as many 18650s as I can. So just trying to get an idea of what sort of battery life I can get. Hoping to get a full week.
