Atari ST USB keyboard and mouse adapter

Moin atari st fans,

 

I came across a project about 3 years ago, which enables a USB keyboard and mouse to connect to an Atari ST.
The project uses a Raspberry Pi Pico with a few additional components.
Optionally, you can also connect 2 joysticks. There are two standard 9 poles. Sub-D (male) connector.

Here is the link to the Github project page: https://github.com/fieldofcows/atari- st- rpikb

Now it was unfortunately the case that the source code for the Raspi Pico was not entirely complete, i.e. there were several error messages during the compilation process.
In the meantime there was one Tip in the commentshow to solve the problem.
But at first I did not investigate this.

I happen to be over one  YouTube video Stumped.
The Youtuber has that compiled program put online for the Raspi so that you don't have to compile the code yourself.

I then tried this with my experimental setup and installed the program on a Raspberry Pico. It is pretty easy by connecting the Pico via the USB cable to the computer. In my case a Mac. When switching on or plug -in of the pico you have to be the button 'Boat'Down. Then you can let go of the button again.  
The Raspi should then mount a drive like a hard drive. 

Attention: first the file atari_ikbd- firmware.zip Unzip.
The one contained in the ZIP is now being copied to this drive atari_ikbd.uf2.
After that, the drive should turn out automatically. Now the program should be installed on the Raspi.

The circuit diagrams and how the whole thing is to be built up can be found on the Original page.

I tested some keyboards and mice. Almost everything is going, just not too much electricity. And unfortunately keyboards and mice go on the logitech unifying radio dongle not.
That means: besides gamer keyboards and mice, as well as logitech radio dongle, most of it is probably the most.

Here is my list of test devices and the result:

The following keyboards and mice worked:
- Raspberry Pi Keyboard and mouse
- Logitech MX518 Mouse
- Kensington USB/PS2 Wired Mid- Size Mouse (M01093, K72355)
- Apple Pro Mouse (Transparent / black, slow)
- Apple mouse Model A1152, white (slow)
- Microsoft Express Mouse MSK1480
- Kensington Expert Mouse K64325
- Das Keyboard 4c Pro
- Apple Keyboard A1048
- 4- port USB- Hub (blue) + HKBD Pro Hybrid Type- S (via cable, CMD: FN-Control-0) + Raspberry Pi Mouse
- 4- port USB- Hub (blue) + Keysonic ACK- 11864 (Radio) + Raspberry Pi Mouse

Have the following keyboards and mice not functions:
- generally keyboards with Logitech Unifying Radio dongle
- SteelSeries Kinzu V3 (Gamer mouse)
- SteelSeries Kana V2 (Gamer mouse)
- Apple Keyboard (white) A1243
- Ducky One 3 SF (Gamer- Keyboard)
- Logitech TK820 With integ. TouchPad (tested without/with USB hub)
- Logitech Dinovo Edge With BT dongle (tested without/with USB hub)

It is important: If the keyboard already contains a USB hub, then the keyboard should not be connected via another USB hub. That doesn't work.
If the keyboard has not integrated a USB hub, you can connect both, i.e. keyboard and mouse, to a USB hub.
What does not work are active hubs, i.e. which with your own power supply. So only use passive hubs!

BTW: I have been researching the project, you can also find it on mine Github account.
