tty2oled Soft&Hardware Add-On (Shows Core based Pictures on a Display)

[venice]

GND wire fixed it

Congratulations.
Do you plan to add it to an case?
If not, can I use this picture for the gallery?

Btw, did you use the TTGO PCB from the Github Repository?

[gojira54]

Yes I used the PCB from your github - works fine =]
No problem to use the pic anywhere, thanks again!

[gojira54]

I made some alt images for PCE, MD, MD-CD, famicom, super famicom & neo geo, attached

I have some problems with tty2oled, i hope someone can help me.
My oled screen is showing mister fpga by sorgelig and the usb icon.

Worth checking /devs to make sure you only have ttyUSB0 listed. Could be that your display is on a different device (I've had extra stuff plugged in and has to send data to ttyUSB1).

Other than that, check baud rate is correct in sketch. All I can think of off the top of my head.

[RealLarry]

I have some problems with tty2oled, i hope someone can help me.

Checklist to get an overview of your setup:

• Type of ESP device, ie ESP32, TTGo, ESP8266 ...
  • Is this device correctly definded in INO? Look for Uncomment ONLY one Board there

• OS you're using to program the ESPxx

• All libs and and board setups are up-to-date? Versions?

• Baud rate set in INO

• PCB in use? https://github.com/venice1200/MiSTer_tt ... _and_Cases
  • or check cabling between ESP and display

• Power source brand, type, amps?

Maybe we could expand and use this form as a quick self-check and to help other more precise.

Moinsen,

• Use and test the binary @venice provided here viewtopic.php?p=25334#p25334

This in the binary for an 1306 Display.

We need definitly more information about your system like RealLarry and Dave18 wrote above.

For checking the MiSTer's Serial Interface to the ESP you can run dmesg from an command line which should show something like this:

Code: Select all

[    1.118601] usb 1-1.1: New USB device found, idVendor=10c4, idProduct=ea60, bcdDevice= 1.00
[    1.118612] usb 1-1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=3

[    1.122272] usb 1-1.1: cp210x converter now attached to ttyUSB0

The CP2104 is the USB-Serial Chip on the ESP (TTGO-T8 here).
The last line is the one we you need.

Good point! Maybe @jawler got an ESP with a CH34X converter onboard which isn't supported at MiSTer side for now, but temporary fix available for this as I'd compiled my own dev-kernel to accomplish this issue. Sorgelig will fix this issue with the next kernel/linux image update: https://github.com/MiSTer-devel/Linux-K ... /issues/22

(I've had extra stuff plugged in and has to send data to ttyUSB1).

Can I ask what kind of device it is?

It was another ESP device!

BAUDRATE="921600"
...
[ 1.416437] usb 1-1.2: cp210x converter now attached to ttyUSB0

The Baudrate in the INI and the Baudrate from the Arduino Sketch must be the same.
Standard is 115200 in the INI File and the Sketch.
Until you don't have another device connected which creates an ttyUSBx Device ttyUSB0 should be your ESP.
Run "ls -l /dev/tty*" and post the result.

And please give more information about your soft- and hardware (see RealLarry's Post) above.

Did you test the Display with the Arduino's Serial Console?
https://github.com/venice1200/MiSTer_tt ... ki/Testing

[venice]

Update
The actual Version of the tty2oled Script got command line parameter for easier testing.

See: https://github.com/venice1200/MiSTer_tt ... -parameter (scroll down)

Make sure you stop the running tty2oled instance before you run tty2oled from the command line.
Run /etc/init.d/S60tty2oled stop from command line to do this.

[jawler]

I'm trying from arduino and send menu or sorg from terminal and my screen never change. Always in MISTER FPGA by Sorgelig. Connecting ok in COM4
I uploaded USB version sketch, checked board (TTGOT8)
I bought:
https://a.aliexpress.com/_uJaCaR
https://a.aliexpress.com/_uiOBYf
I don't use a microsd on the ttgo
I don't know what's wrong.
Thanks for your help and patience.

[venice]

Did you check/set baudrate and line mode in the terminal?

We still need more information about your soft- and hardware (see RealLarry's Post) above.

[jawler]

Thanks @venice for your support.
In arduino's serial com doesn't work but after several resets on ttgo it worked once. So i can think the problem could be on dupont cables. I'll try to solder some wires tomorrow.
Thanks again, for your help.

[RealLarry]

i can think the problem could be on dupont cables. I'll try to solder some wires tomorrow.

While having a heated solder iron have a close look at the solder points of your display where you're connection wires to. I'd fixed a similar issue with one of my displays where I'd found a resoldered a cold joint.
viewtopic.php?p=25102#p25102

[jawler]

good morning, i resoldered and revised everything but i stuck at testing on mister:

/root# /usr/bin/tty2oled /dev/ttyUSB0
/dev/ttyUSB0 detected, setting Parameter.
Read CORENAME: -MENU-
Send -MENU- to /dev/ttyUSB0.
Setting up watches.
Watches established.

It seems connection is done but the screen it's not changing. any idea?
Thanks!!!

[venice]

At first we need to make sure that the ESP and the display are working and the serial interface is OK.
Therefore I need you to test with the Arduino’s Terminal again.
This MUST work.

Double check baudrate and line option in the terminal.

And we still need information about your soft- and hardware (see RealLarry's Post above).
Are you using Windows or Linux?
Which Arduino/ESP Version etc.

This MUST work. I know, all instructions are clear. I feel dumb.

I'm using arduino 1.8.13 on windows 10 x64. I installed all the libraries following the tutorial.

I don't know why yesterday (in arduino) after several resets on the esp32 worked just one time.
I have 2 esp32 but it's the same on both.
Thanks a lot.

[venice]

...
Thanks a lot.

I also got sometimes messages in the terminal when one of my ESP32's is connected.
How big is your Flash Memory? Did you order the 4MB or 16MB Version?

I send an PM.

[jawler]

I ordered 16MB.
I replied your pm

[jawler]

Now it's working perfect in arduino!!! i'll have no problems on mister for sure.
The problem was in a gnd wire.
Thank to everyone!!! xD

Great

I have taken the GND problems as an opportunity to update the connection drawing a little bit .

Minor Update
RealLarry updated the USB Mode Sketch a little to enable Transition Effects for the NodeMCU ESP8266.
No need to Update if you use an ESP32.

I've been really interested in trying tty2oled, especially with the new USB support. I've found the "what to get" part really confusing. I'm hoping by sharing I'll help other folks like myself.

I first bought two of the LILYGO TTGO T8 V1.7.1 ESP32 4MB boards from eBay, plus two BuyDisplay Serial SPI 3.2" inch OLED Module Display 256x64 w/Breakout Board screens.

First I got everything in, programmed the Arduino, and was able to see ttyUSB0 on my MiSTer. Then I tried wiring the board and screen together. First, I wanted to use Dupont wires rather than soldering. Fortunately I'd purchased some small breadboards, so I was able to push the Dupont wires through the holes in the board and screen to wire them up. Getting the screen to sit on the breadboard was a challenge however, since there are tabs on the back that stick out. Unfortunately the screen didn't work - probably because it is not set to 4SPI mode by default. I have zero interest or ability in soldering, so changing this is problematic.

I decided to give it all another go with the following:
ESP32-DevKitC core Board ESP32 Development Board ESP32-WROOM-32U
Screw Terminal Block Breakout Module Board for ESP32-DevKitC
3.2 inch Arduino,Raspberry Pi OLED Display Module 256x64 SPI with the pin headers and 4SPI mode

With this I can use female Dupont wires on the screen and bare wire on the other end into the screw terminal. This and the screen in 4SPI mode from the factory I believe that will offer a solder free solution for building the tty2oled board and screen.

[Reg]

Good Evening !

So finally got all my bits for this and think I've built everything right - but not near the MiSTer until tomorrow.

This is what I've ended up with...

Info.jpg

...I've taken the image from the post from Fri May 07, 2021 7:41 am from Vince and applyed to a FAT32 card in the TTGO.

When applying power, the TTGO board looks like it powers up but nothing appears on the screen. I know that I've not got any core's loaded or even by the MiSTer until tomorrow, but can anyone confirm if the screen would stay blank until the scripts from the MiSTer are run ?

Eager to know if all the work done here is expected behaviour so far.

Thank you.

[dave18]

The screen should display 'Mister FPGA by Sorgelig' if not connected to an actual Mister device.

I believe Venice has stated that the TTGO is not selected by default in the latest Sketch source so make sure you uncomment the correct define (and comment any others)
