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

[Mellified]

How old is the Arduino Programm you have downloaded?

I downloaded it again today to be sure. Confirmed the lines you mentioned are present.

If that's the case change the cables at the terminals 5 + 17 (Blue +White) or the two cables at the Display side. The others are looking good.

Code: Select all

Terminal 5  = Display Pin 16
Terminal 17 = Display Pin 15

Set the Arduino IDE to "Wemos Lolin32" and upload the program.

If the Program and the ESP are OK you should see at least "MiSTer FPGA by Sorgelig" after Power on.

//Edit
I think we have to change the electrical's for Devkitc and Lolin32.

Yup! Once I switched the blue and cyan/white wires on the screen it worked immediately.

So here is a test solderless option for the lazy/incompetent!

Fix to git commited. Again, sorry for any confusion.
I like your terminal solution. Seems to make life easier if replugging wires a thousend times.

Yeah, it make this fix a 2 second thing rather than having to re-solder.

@venice - So now that I have a working display I'm looking to add support for the tty2oled to MiSTer_SAM. The arbitrary text support should make it really easy to display the game/MRA name rather than the core name. A few issues I'm seeing though that may be easy to fix?
1. It would be better to have a fixed width font so I know how many characters can be displayed. Right now I can get 12 "W" on screen or up to ~18 narrower characters.
2. A two line display option would be interesting - show the core name on one and the game name on the other.
3. When text overflows the display the text is centered and truncated. Would it be possible to automatically scroll the text across the display? Even moving one character over each second might be sufficient.
4. Using 'echo "This is a fun game" > /dev/ttyUSB0' works - but the tty2oled daemon will overwrite when it notices /tmp/CORENAME has changed. I can run "/etc/init.d/S60tty2oled stop" when MiSTer_SAM runs, of course, but that could fail to restart if SAM doesn't exit cleanly. Is there a way to disable CORENAME monitoring temporarily? Or send arbitrary strings to the display with tty2oled? I tried '/usr/bin/tty2oled /dev/ttyUSB0 USB 921600 > "Donkey Kong"' for example.

Another working tty2oled, great

Related to 1+2:
Did you try the new TEXTOUTXY Function from above?
See: viewtopic.php?p=27974&sid=f7599536876c9 ... 0d8#p27974

But this recommends an stopped tty2oled daemon
or usage after/between core change(s)
and the actual version of the Arduino Program.

The „standard“ Text output via the tty2oled daemon is just for showing the corename if no picture is available.

Could you make a picture for the gallery of your hardware setup showing something on the display.

I saw it but didn't register the text sizing. I will disable the daemon and give that a shot!

Here you are!

This is what I got so far. The animated GIF is low quality to get the file size down and the converter changed the text from blue to yellow for some reason, but hopefully it gets the idea across!

This is what I got so far...

Looks good to me
Is this this something you can work with?

[Mellified]

I had a bit of trouble with the spacing at first. The text starts at the bottom left of the pixel grid coordinates - not the top left as I’d assumed. Once I understood that it was pretty easy.

Overwriting existing text with more text could unlock some interesting visuals. I wasn’t creative enough to come up with any myself though.

It would be nice to have a way to blank only part of the screen. I tried overwriting text with spaces but that had no effect.

Note I am disabling the daemon. Nothing to do with tty2oled but SAM lacks a consistent exit code block currently so I’ll need to refactor to ensure the daemon is re-enabled in all code paths.

Other than that the code is “done” after a few hours. I’d like to get some more testing from other tty2oled users. I’ll post when it’s ready.

[Mellified]

OK, tty2oled support has been added to Super Attract Mode! You can download the files here:
https://github.com/mrchrisster/MiSTer_SAM

You will need to enable support in the MiSTer_SAM.ini - it is not on by default. Of course, tty2oled will display the corename as usual if you don't enable this support.

Please post any issues to the SAM thread here:
viewtopic.php?f=29&t=2493

Jepp, that's my standard setting.

It looks to me the fonts I added are "transparent" fonts and don't overwrite the background.
The used font are u8g2_font_luBS08_tf, ..10, 14, 18 & u8g2_font_luBS24_tf.
Take a look here https://github.com/olikraus/u8g2/wiki/fntlistall for an list of fonts.
"Transparent" fonts have an "t" in the font name like "u8g2_font_u8glib_4_tf".
I can add some fonts for you if you like, we have enough space in the ESP.

Ok

[Mellified]

That'd be nice. If you have the space put the non-transparent equivalent of each of the existing ones on perhaps? That'll allow all sorts of special effects for whatever sizes.

I haven't found the same Font as Non-Transparent but I added 4 new Non-Transparent Fonts which have a smaller width and one "Icon" Font .

See here https://github.com/olikraus/u8g2/wiki/fntlistall for how they look like.

Code: Select all

0:  u8g2_font_luBS08_tf    (20x12, 8 Pixel A, Transparent)
1:  u8g2_font_luBS10_tf    (26x15, 10 Pixel A, Transparent)
2:  u8g2_font_luBS14_tf    (35x22, 14 Pixel A, Transparent)
3:  u8g2_font_luBS18_tf    (44x28, 18 Pixel A, Transparent)
4:  u8g2_font_luBS24_tf    (61x40, 24 Pixel A, Transparent)
5:  u8g2_font_profont12_mf (6x12, 8 Pixel A, Non-Transparent)
6:  u8g2_font_profont17_mf (9x17, 11 Pixel A, Non-Transparent)
7:  u8g2_font_profont22_mf (12x22, 14 Pixel A, Non-Transparent)
8:  u8g2_font_profont29_mf (16x29, 19 Pixel A, Non-Transparent)
9:  u8g2_font_open_iconic_all_2x_t (16x16 Icons, Transparent)

Font Size Values are Width x Height and the Height for Character A

Fonts 0-4 are the original Transparent Fonts, 5-8 are 4 new Non-Transparent Fonts, 9 is an 16x16 Pixel Icon Font.

The Format is "xxx,yy,f,[Text]" (f instead of s )

Code: Select all

xxx = 3 Digits X-Position 000..255
yy  = 2 Digits Y-Position 00..63 
f   = Font Type, see list above

If we need more fonts I have to change "f" from 1 to 2 digits.

Example

Code: Select all

1: echo "att" > /dev/ttyUSB0                # Is needed
2: echo "TEXTOUTXY" > /dev/ttyUSB0          # Enable TEXTOUTXY Mode
3: echo "010,20,5,Text Out" > /dev/ttyUSB0  # Show "Text Out" with Font 5 at Position X=10,Y=20.

I hope this helps

[Mellified]

I hope this helps

Unfortunately the new fonts don't overwrite existing ones it seems. I also tried using the symbolic font, but those didn't overwrite either. Not the end of the world - the support as-is works well. The new fonts are a little more stylized, which gives a different aesthetic. May be nice for some use cases!

[venice]

Should do, just tested.

...I also tried using the symbolic font, but those didn't overwrite either.

The Icon Font is also a Transparent one.

[venice]

Minor Update USB Version related to TEXTOUTXY
No need for leading Zero's for X and Y Values.
The Format is now "x,y,f,[Text]", fully compatible to the old format "xxx,yy,f,[Text]".

Code: Select all

x = X-Position 0..255
y = Y-Position 0..63 
f = Font Type 0..10

Enabled Font 10

Code: Select all

10: u8g2_font_lucasarts_scumm_subtitle_o_tf (Nice 12 Pixel Font, Transparent)

EDIT : figured it out, see bottom for pinout for this display, if anyone purchases from digikey, mouser etc... and uses it with ESP8266 NodeMCU

Ok so i've uploaded the arduino code to the esp8266, but I don't think the pinout of my display matches with the picture on the wiki...

From what I gather from the spec sheet, i'll have to ground pin 19 and 20 to set it to 4-wire serial... But the rest some don't match?

Zo3EmTc.png

Pin 1 and 2 remain the same as the picture...
Pin 3 no connect, but looks like I need to ground pin 6 ?

Need help for the rest...

This is the display :
https://www.newhavendisplay.com/specs/N ... 64UCY2.pdf

EDIT pinout for display that works with ESP8266 NodeMCU :


Pin 1 : GND
Pin 2 : +3V
Pin 3 : NC
Pin 4 : D2
Pin 5 : GND
Pin 6 : GND
Pin 7 : D5
Pin 8 : D7
Pin 9 : NC
Pin 10 : GND
Pin 11 : GND
Pin 12 : GND
Pin 13 : GND
Pin 14 : GND
Pin 15 : NC
Pin 16 : D1
Pin 17 : D8
Pin 18 : NC
Pin 19 : GND
Pin 20 : GND

Specifically, writing a " " (space) character doesn't create a blank area under it no matter which font type I use. I was hoping to do this so I could wipe part of the screen - not the whole thing with "cls".

Weird, this works for me. Tested from the Arduino Serial Monitor under Windows.

Did you update the Arduino Programm to the latest version after I added the new fonts?

Anyway, I will try to add a command to to draw rectangles filled/unfilled in front or background colour.

Nice that you have the possibility to set the Display-Mode via MCU.

Yeah it's nice to set it via MCU, didnt see myself unsoldering and resoldering those tiny resistors... But I'm sure the display is more costly though

You inspired me with that 8BitDo.

Had to get one ( and do a little swap of some buttons and the stick ), what a lovely bit of kit.

I also disconnected the power from the symbols that appear by the buttons and updated the firware from ( https://support.8bitdo.com/ultimate/arcade_stick.html ) which allows you to assign a keyboard button to P1 and P2 so they can now be used with the MiSTer as they are seen as a keypress.

My updated stick...
