Re: [Guide] ili9341 SPI TFT Screen on Retropie
hi @moosepr are you aware if it is possible to adjust the brightness on these screens?
due to them seeming to be designed to be used in portrait not landscape when i look dead on its a little dark compared to looking at it at an angle, i feel if i could increase the brightness a bit it could be much more usable, i am currently using one in a new build inspired by veterangamer

Re: [Guide] ili9341 SPI TFT Screen on Retropie
Hi there. It is possible to make the screen dimmer, but not normally brighter. The boards are designed to be 5v safe and so when you run them on 3v they can be a little dim.Lpoolm wrote: ↑Fri Jan 05, 2018 11:29 amhi @moosepr are you aware if it is possible to adjust the brightness on these screens?

Sometimes the red PCB's have jumpers on them which allow you to bypass some of the backlight resistors and can possibly give a brightness boost
Get a small cheep LCD in your project https://www.sudomod.com/forum/viewtopic.php?f=22&t=2312
Wrap it all round a battery https://www.sudomod.com/forum/viewtopic.php?f=13&t=2292
Or use a custom PCB to make it really small https://www.sudomod.com/forum/viewtopic.php?f=13&t=2512
or make it really really really really tiny!! https://www.sudomod.com/forum/viewtopic.php?f=13&t=2919

Re: [Guide] ili9341 SPI TFT Screen on Retropie
Solved read below Moosepr Im a complete noob with this stuff and having trouble installing the clone software. I got the display runing and booting up on reboot following your guide just still have to type "con2fbmap 1 1" in terminal to get the terminal on it but thats where im stuck.
sudo apt-get install cmake
git clone https://github.com/tasanakorn/rpi-fbcp
cd rpi-fbcp/
mkdir build
cd build/
cmake ..
make
sudo install fbcp /usr/local/bin/fbcp
At this point the screen scrolls through a bunch of lines and ends with "E: unable to locate package /usr/local/bin" and alot of lines ontop of it with same this just different packages unable to find.
Wow i am so dumb please disregard this if anyone is having this problem just run each line of code by itself lol i type the whole thing in one big line.

Re: [Guide] ili9341 SPI TFT Screen on Retropie
i have followed this guide before and worked great, however i have completly forgot what the command line i need to be able to adjust the screen speed and add fps 60.
i thought it was /etc/modprobe.d/fbtft.conf but when i type this i get permission denied?

sudo nano /etc/modprobe.d/fbtft.conf

Re: [Guide] ili9341 SPI TFT Screen on Retropie
i've designed some boards that i feel will make working with these screens a little cleaner....
(a big thanks to Moosepr and Helder for their help & support)
these boards are shared and avaialble on Oshpark.....
they work flawlessly.....
and avoid the need for wires, allowing you to use these screens in more confined areas (you still have to allow for the board)
The boards
https://oshpark.com/shared_projects/IzZ86uBr
https://oshpark.com/shared_projects/1tm0wj1M
https://oshpark.com/shared_projects/6WirTrF6
you have a board for a forward/straight ribbon cable (8 Pin 1.0mm Pitch)
and another if you plan on using a reversed (8 Pin 1.0mm Pitch)
(this is based on if you use bottom contact ribbon connectors)
other bits
Ribbon Cable
Custom Lenght Ribbon Cable
1.0mm Pitch FFC/FPC Flat Cable Connector
0.8mm Pitch FFC/FPC Flat Cable Connector
(the 0.8mm pitch connector for the screen isnt needed if you solder the screen to the board)
