Introducing the T-COMPUTER platform...

[Jean-Marc]

The T-COMPUTER is an attempt to create a complete micro computer around the Teensy MCU.

It is based on the Teensy 4.1 (my favorite MCU so far!)
See the details of the project below.

https://github.com/Jean-MarcHarvengt/T-COMPUTER/blob/main/README.md


It is fully open source and it is a DIY project so you are free to build it yourself for non commercial use of course

It is using the MCUME project for the SW part, see below latest updates of the MCUME as Super NES emulator running full speed on the platform

Hi Marc,

I want to build your T-Computer with MCUME to present it as little "Event" in our Retro Area for the GamesCom'25 which is running right now in Cologne.

Couple days ago the Folder MCUME was still bounded and finished to deploy, I believe I'd copied it into
"C:\Users\UserX\AppData\Local\Arduino15\packages\teensy\hardware\avr\1.59.0\libraries". But today I was forced to "clean" the whole Teensy 4.1 Package and wiped it (due Problems with SD, SdFat and MTP_Teensy). After Re-Installing MCUME it won't appear anymore in the Sample Folder. No matter what I try. Not in the Folder mentioned above nor in my custom Folder under C:\Arduino\libraries. Everything is up-to-date but I get white hairs due nothing want's to run. What do I wrong?

@PaulStoffregen , @KurtE , @defragster , anybody?
I really need urgent help and would be much apprechiated for your kind duties.

I believe it would become a big Highlight at the Retro Area

The p#1 github link is still valid - and it has a BIN folder of HEX files ready to load onto the T_4.1.

Not sure if there were sources before - but they are not there now.

A download of the zip file and extracting would give the files to upload.

Many thanks bro. The Repository is still there and what I've realized is, that Doom is working with the right setup, even with the HEX, (except Audio (PT8211)) but all the other not. It's like "Jean-Mark" removed some Folders or Files on purpose, so that an compile is no longer possible and you must use the HEX Files instead. Anyway it looks like that. Descriptions like pinout.txt for the T4.1 isn't in that folder where the Teensy41Files and Subfolders lies and a common Description like the one for the T4 isn't useable in common because it's not everything declared for the T41. Then, I tried to setup Teensyuae (T4.1) and used the SPI1 Block with ILI9341 (not yet VGA ready). Wireing as shown in the "iopins.h", TFT_RST settled to 255 (3.3V). It works with DOOM fawless but anyone else ain't and I don'T know - WHY althought it'S the same setup - and the screen is just a whiteout. I checked the cables (use for Proto a large Breadboard), everything is okay. I saw, that you had answered several times to the MCUME Topics and would like asking you, is you familiar with the Audio Problem? As I mentioned before, wireing is okay all around. That's why I assume the error is anywhere within the code but not obvious to see.

I've setting it up to this:

and I can't see any Problems with SND and PT8211... Do you have any clue what's goning on there?
Even Audio is okay (7, 20, 21)

(Should we move the topic or still discuss here?)
