80sTV Build Software02

installing monitor drivers
git clone github.com/goo...
add permissions to the LCD-show directory
sudo chmod -R 755 LCD-show/
move into the LCD-show Directory
cd LCD-show/
activate the proper monitor (if purchased off the materials list, this is a MPI3508 monitor)
sudo ./MPI3508-show
wil reboot automatically..you'll need to SSH back into your PI
alter the config file
sudo nano /boot/firmware/config.txt
remove the “#” from overscan left and right
overscan_left=-10
overscan_right=35
use down arrow key to get to “display_rotate=0”
display_rotate=2
Add the audio configurations while your in the config.txt file
above “[all]' type this code
dtoverlay=audremap,pins_18_19
(I misspelled audremap in the video..thats wrong)
Ctl+X to exit out of nano and save the file
sudo reboot
SSH back into your pi
sudo raspi-config
Activate Audio output ...select
System Options - Audio -headphones
then turn VNC back on
Interface Options VNC Yes
hit TAB to finish and exit out
sudo reboot
you now can use VNC to log in and remote desktop your Pi
to access your Pi thru your explorer go to your “Network”
\\80TV
from there you can mount if you like or just access it
To shutdown properly use Shutdown from VNC or
sudo shutdown -h now

First of all, thank you so much for this guide! It was super helpful and I followed all the steps - 3D printed all parts (including the spacer), painted it with the same colour scheme :) and then assembled the hardware (after waiting patiently for the right parts to arrive from AliExpress). I had some issues with the HDMI FPV plug (mini) rubbing against the frame, the angle adaptor for USB-C as well rubbing on the frame so had to use a Dremel and cut a piece out. I finally got it all going, yay!
The one thing that was a bit frustrating for me to debug was audio. I think there's an error in your video (typo). You ask to add the following lines -
dtoverlay=audermap,pins_18_19
=>
dtoverlay=audremap,pins_18_19

I'll double check that..thanks for point it out..*UPDAT* ...you are correct I misstyped it in the video..but its coorect in the description of comandlines to copy/past..I noted it in the description that I miss typed it.

Hi, I'm having an issue where, once i install the LCD drivers MPI3580-show, the AUDIO HAT module stops playing sound. I tested it before installing LCD drivers and works fine, I add dtoverlay=audremap,pins_18_19 and chose headphones in Raspi-config but still no sound coming from the AUDIO HAT speakers. Please help

after I installed "MPI3508-show" and rebooted raspberry, it shows black screen. Btw whatever settings I write in the config.txt it will be black screen after rebooting. Raspberry pi 4.
Is there any chance to change screen resolution?

[@a.d.d.theater8023]

you sure your using the correct driver??..if so, try ssh into it and adjust the raspi-config and turn on vnc..if you can vnc and see the desktop..that means you prob have the wrong driver..and there is nothing wrong with the monitor..if that doesnt work..try just unplugging your monitor, and ssh/vnc into the pi. if everything works..its definately a driver issue. you can actually remove or pass thru all the driver settings in the config..by putting a "#" in front of all the HDMI commands in the config.txt file. And turning them on one by one till you find the culprit. There is a lot of resouces when dealing with the HDMI config..to beable to tell you the perfect handshake here is unrealistic..All I can say is confirm your model of your LCD screen, make sure you HDMI plug is in ...and its seated on the headers firmly.
Technically it should work without the drivers, ..the drivers allow you to use the touch screen if your monitor allowes it..and drivers let you manipulate how its served up to you..like rotating it, changing its refresh,..in the case of this projects, it needs to be rotated and adjusted to the Left so it fits in the tv window. .But if your using it just as a monitor..then drivers shouldnt be needed.

@@a.d.d.theater8023 I understood that this display MPI3508 from aliexpress is shit for raspberry pi4b. It cant read settings from config.txt properly, it cant run with other resolutions, I cant rotate display even. Piece of shit that ruined whole project.

[@a.d.d.theater8023]

@@avee_maria sorry you had an issue with the monitor..I purchased mine from Aliexpress and it works just fine. mabe its a hit/miss sort of thing. Not sure how you cant read the settings from the config.txt..if you type....
sudo nano /boot/firmware/config.txt.......nothing comes up in Nano??

[@paultakita]

same here... black screen with a blinking cursor. Do i have to start all over now? @a.d.d.theater8023 ?

[@a.d.d.theater8023]

@@paultakita can you ssh into it? if so Go to the config.txt file found in /boot/firmware/config.txt
