Kicad project is within the attachments. I also attached the case design. Within the case I've used foam to stop the Display/MCU from moving:

please find the Gerber files within the attachment. I've used M3 nuts with an outside diameter of 4.6 mm and 6 mm length.

Thank you for your support!
I hope the ch340 is supported as soon as possible.

I used the ESP8266 NodeMCU CP2102.
I had a pcb for NodeMCU V3 but it was not available.

Yes, Great
Did you had problems to get it working?

I used the NodeMCU V3 PCB and NodeMCU V3.
The NodeMCU V3 uses a ch340 chip.(? Is the chip the right name? )
But I don't think there's a ch340 driver in Mister.

Your're right - the driver for CH34x devices isn't compiled into MiSTer's kernel yet. I've opened an issue at Sorgelig's kernel repo to include the kernel module for the next time he'll compile and publish one and he accepted.
For the meantime I compiled my own one months ago as I'm using a NodeMCU V3 too. I've pushed this kernel to venice's repo now, so have a look to it.
To be sure that nothing can go wrong backup or rename the original kernel zImage_dtb (at /media/fat/linux/ on MiSTer's tf card) and replace the file with the repo's one. Reboot and enjoy the result

Pretty good coverage!

https://docs.google.com/spreadsheets/d/ ... edit#gid=0

Might be of use to people into making the images to see what is currently missing. I need to finish reading through all the wikis for the project and get my head around how it works for arcade cores, but can add those to the list later on.

If this is useful and anyone wants edit access to the file just let me know.

We have no experience with an CH340 NodeMCU v3, so we need to test.

Which Arduino version do you run. USB or SD?

Run the command

Code: Select all

stty -F /dev/ttyUSB0 

from an MiSTer's Terminal (SSH,CLI) after the tty2oled daemon has done the tty setup and post the result.

Could you try the test command bye from the Arduino Terminal or run

Code: Select all

echo "bye" > /dev/ttyUSB0

from the MiSTer's Terminal.
Double check the baudrate.
See https://github.com/venice1200/MiSTer_tt ... ki/Testing

Moondandy wrote: ↑Wed Jul 07, 2021 9:21 pmA couple of questions:
Could software run on Linux like ScummVM get an image?

echo "scummvm" > /tmp/CORENAME

For arcade games that share the same core, like CPS2, do the individual games get an image or an umbrella one for the hardware they run on?

To get a "feeling" about your environment, it's best to have a look at our mini FAQ at viewtopic.php?p=25890#p25890
Please read and check this carefully, then post your results. Maybe we are getting a better comprehension about your setup and problems then. Most of the time, specially when "it works but has hickups", the culprits are cabling (bad USB cable, solder points, connections ...).

just different NudeMCU Version. CP2102 is Good work.
I will try to connect another NodeMCU V3 tonight around 11pm (KST). Thanks!
