Last post by LubOlimex - January 12, 2026, 09:44:44 AMTry with this code (download the whole repo):
https://github.com/OLIMEX/MOD-LCD2.8RTP/tree/master/SOFTWARE/Arduino/graphicstest_olimex_NS2009
Make sure PSRAM is enabled in your board selection options (this is specific for WROVER boards).

ESP32 / ESP32-POE-ISO-WROVER rev L + M...
Last post by daybreak - January 11, 2026, 10:46:11 PMESP32-POE-ISO-WROVER rev L + MOD-LCD2.8RTO rev D the Display only shows backlight LED. I could not activate the display with text. I have tried a lot of variants in the code. Are there any special things to make it work?
the uext gpio set up is:
| UEXT-Pin | Signal | ESP32-GPIO | Funktion |
|----------|--------|------------|----------|
| 1 | 3.3V | 3.3V | Stromversorgung |
| 2 | GND | GND | Masse |
| 7 | **MISO** | **GPIO19** | **D/C (als Output!)** |
| 8 | MOSI | GPIO23 | SPI MOSI |
| 9 | CLK | GPIO18 | SPI CLK |
| 10 | SSEL | GPIO5 | SPI CS |

NXP / Re: Case for iMX8MP-SOM-EVB-IN...
Last post by ilario - January 11, 2026, 07:44:35 PMQuote from: sndsgd on November 13, 2025, 01:09:58 PMIf you want to get dimensions while you're waiting for the hardware to arrive, you can get them from the kicad files on github: https://github.com/OLIMEX/iMX8MP-SOM-EVB.
It is exactly what I tried to do, but surely I have done mistakes of millimeters here and there.
I was waiting for having my hands on the actual device for correcting the positions, but my work condition changed, and I don't think I will make a case for the device nor that I will have the device at all.
Please feel free to take the draft linked above, improve it and push it upstream.

UEXT / Re: MOD-IRDA faulty ?
Last post by LubOlimex - January 09, 2026, 03:31:43 PMIndeed, thank you for your research. I got back to testing this and the distance is up to 2.5-3m which is unexpectedly low, we determined that the LED is simply small for better distance. The engineers wanted to save space but it is not worth it. In future we would switch to 5mm IR333-A, which seems to improve the range to around 10m which is much better. Thank you for reporting this.

FPGA / toolchain for GateMateA1-EVB
Last post by mastupristi - January 04, 2026, 06:12:38 PMHello,
The document ug1002 "Toolchain Installation User Guide" is listed on your website.
Inside I find:
Following the directions, however, I find this:
https://colognechip.com/programmable-logic/gatemate/toolchain/
It seems that document ug1002 describes the legacy toolchain called cc-toolchain-linux.tar.gz,
but as you can see on the page, the most recent toolchain is oss-cad-suite-linux.
However, I cannot find any usable examples in this new toolchain.
I found some examples (perhaps) that could be useful here: https://github.com/YosysHQ/prjpeppercorn-test-cases
What do you think about using the new toolchain?
Do you have any quick guides on this? Or even just suggestions?
regards
Max

Last post by mastupristi - January 04, 2026, 05:40:57 PMHi,
I found this: https://youtu.be/lMUQplZXPoM?si=BMzlcv0eBE_oDg0y
Where they referred to the 'blink' example.
It is present in the toolchain, but it needs to be edited to change the pin definition, which is set to CCGM1A1-E1 by default.
I searched on GitHub and found a couple of repositories that contain the blink example with the pin definition for Olimex:
I hope this helps others.
regards
QuoteNo idea. Some bit file was provided by Cologne community if I remember correct. The software usage is detailed here: https://github.com/OLIMEX/GateMateA1-EVB/blob/main/SOFTWARE/ug1002-toolchain-install-latest.pdf

Neo6502 / Re: Creating ARCADE games for ...
Last post by Maarten van Druten - December 24, 2025, 06:02:09 PMWhile trying to build the game I found out problems,
The makefile uses ca65 (cc65 assembler) but the source code was written in 64tass syntax!
So I am fixing this now and will upload the right files on github soon

Neo6502 / Re: Creating ARCADE games for ...
Last post by Maarten van Druten - December 23, 2025, 08:31:26 AMI posted my files on GitHub:
https://github.com/MishaOpenArcadeSystem/Gaudens-Machina-EX
Who can help me to accomplish following goals:
1 - Make this game work on Olimex NEO6502
2 - If the game works create a manual how to configure the Olimex NEO6502
so it boots automatically into the game when turned on

Goals I would like accomplish:
- Bring new life in the Open Arcade scene by sharing code, games
encourage other game makers to make real 8bit Arcade games!
- When the Arcade games are finished, I would like to make real wooden Arcade cabinets
(like Barcade) for each game, and share building plans, etc.
- Boost sales and popularity for Olimex :-)
