Unfortunately not. I have checked Pin 1 again with a multimeter and its definitely getting ground. Mmm.

Regards

I mentioned the project there and hopefully it will bring more interest. Although there are already 90k+ views of this thread so clearly there are many in the community that follow it. I have been keeping a close eye on developments for several months now and am extremely grateful to Venice, RealLarry, Jukk@M, and everyone else who made TTY2OLED so awesome. It definitely is the highlight of my setup!

Not just yet. I've got extra components on hand and am putting some kits together to sell in order to help cover the cost of the 3D printer and other items I picked up for this project. I do have a handful of extra OLED screens (modified for TTY2OLED), NodeMCU modules, and adapter PCBs available as well for anyone that wants to add a screen to their current build.

#echo "CMDCLST,0,0" > "${ttydevice}"   #  0 = No effect

#echo "CMDCLST,-1,0" > "${ttydevice}"  # -1 = Random effect

...I ordered a bunch from JLCPCB and have them available (with or without the pin connectors)

Here is my slightly modified Version.
After the logo is shown I use effect 19 (Warp) to fill the Screen completely and then clear it with random effect .
Then the text is shown using a loop from 1 to 15 (or 1..15/3 for the last line).

The major difference is that I use a function to wait for the tty2oled command response after each "echo".

Code: Select all

#Fill transition
echo "CMDCLST,19,15" > "${ttydevice}"
waitforttyack
sleep 0.2
#Clear transition
echo "CMDCLST,-1,0" > "${ttydevice}"
waitforttyack
sleep 0.5

Code: Select all

function waitforttyack() {
  #echo -n "Waiting for tty2oled Acknowledge... "
  read -d ";" ttyresponse < ${ttydevice}                # The "read" command at this position simulates an "do..while" loop
  while [ "${ttyresponse}" != "ttyack" ]; do
    read -d ";" ttyresponse < ${ttydevice}              # Read Serial Line until delimiter ";"
  done
  #echo -e "${fgreen}${ttyresponse}${freset}"
  ttyresponse=""
}

If you like try and report!
MiSTer Arcade doesn't work for me.

What if the logos would change to the next one every x seconds (user defined), while running a core. That would be a nice incentive for more alternative logos and help against the display burning in. No idea how hard that would be to add though.
