UEXT / Re: MOD-IRDA faulty ?

Last post by SirExie - December 09, 2025, 02:47:20 AM

Yes, I have tried a few remotes, but nothing seems to come through.

I did notice this in the console:

Code Select Expand

Reconnecting to /dev/cu.usbserial-1430 .... Connected!
...WiFi connected at: 10.1.30.6
Use this URL to connect: http://10.1.30.6/
Webserver started...
**************************************************************************************************
Thank you for using the IRremote library!
It seems, that you are using an old version 2.0 code / example.
This version is no longer supported!

Upgrade instructions can be found here:
 https://github.com/Arduino-IRremote/Arduino-IRremote?tab=readme-ov-file#converting-your-2x-program-to-the-4x-version

Please use one of the new code examples from the library,
 available at "File > Examples > Examples from Custom Libraries / IRremote".
Start with the SimpleReceiver or SimpleSender example.
The examples are documented here:
 https://github.com/Arduino-IRremote/Arduino-IRremote?tab=readme-ov-file#examples-for-this-library

Or just downgrade your library to version 2.6.0.

Thanks

So I'm still at a loss if its the hardware or the code, but either way, it's not working.

Did you try clicking some remotes on it?

I tried the example program, it provides a web server and after initializing MOD-IRDA it states "Connected", but does not seem to show anything else or allow me to send anything.

If I cant get it going tomorrow, I'm going to assume the LED is broken and try de-soldering it and swapping it out.

1. Thanks for notice. It is now uploaded.

2. No 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

3. Yes, we published the uf2 file that we ship the boards with, here: https://github.com/OLIMEX/GateMateA1-EVB/tree/main/SOFTWARE/dirtyJtag

I believe we took it from here: https://github.com/colognechip/gatemate_ila/tree/main/Olimex_DirtyJTAG_firmware

It is popular board, you can find a lot of projects online, like check this one:

UEXT / Re: MOD-IRDA faulty ?

Thankyou LubOlimex,

I think the question was - is there any way of testing the MOD-IRDA outside the code ? like, just electrically ?

In the meantime, I'll try compiling the demo and see if I can get it to transmit something useful.

Which A20 OLinuXino board more specifically? These have different requirements. Is it MICRO, LIME, LIME2, SOM, BASE-SOM.... What is your setup? What do you have connected to it?

The problem is somewhere in your software. We've used MOD-IRDA with ESP32-POE boards in the past, specifically in this big web-server demo:

UEXT / MOD-IRDA faulty ?

Last post by SirExie - December 06, 2025, 02:49:38 PM

Hi Folks,

I have a MOD-IRDA I'm using with an ESP32-POE-ISO-IND. The UEXT port makes this simple, but I have not been able to transmit via the module.

I'm using ESPHome, and I have it set to use GPIO4, but the client device never responds. I tried filming with the phone camera, but the IR is not visible.

I then tested the UEXT port using a Saleae, and all the pins work fine and I could even decode IRDA.

So my final test was ti check resistance across the the IR LED, and testing both polarities at 200 Ohm was an open circuit. Not what I expected, so I think the LED is faulty ?

No point posting it back, the local electronics shop have 3mm IR LED's for $1.50 so I'll try swapping this out first and see how I go.

How likely is it that this is the problem ? is there any other test I can do ?

FPGA / Questions about GateMateA1-EVB...

Last post by mastupristi - December 06, 2025, 12:04:51 PM

Hello,
I have some question on GateMateA1-EVB-2M.

• I bought the card and saw that it is Rev C. Here https://github.com/OLIMEX/GateMateA1-EVB/tree/main/HARDWARE there are only Rev. A and B. Can you also publish Rev. C?
• Where can I find the VHDL or Verolog sources for the FPGA configuration with which the board is shipped?
• DirtyJtag (https://github.com/OLIMEX/GateMateA1-EVB/tree/main/SOFTWARE/dirtyJtag) is the Firmware that run on RP2040, isn't it?

best regards
Max
