Handheld Recalbox

[pinuct]

Hi, I can't upload the file, i don't know why.   About FBTFT, it is already integrated with recalbox in the beta of the new release. The part that it's missing is the FBCP. So if the team include the FBCP compiled file in the next release it will be awesome, because then we will have al the elements necesary for a TFT screen to work with the GPIOs of the raspberry. The fbcp program is very very lightweight so i don't see any problem to include in recalbox if we ask them politely. And a lot of people will be happy (me included) to use recalbox in a portable console. Thanks.

Ok so we only need to add this binary to recalbox ? https://github.com/tasanakorn/rpi-fbcp

Hi rockaddicted, Yes, with the fbtft already in the beta, the only need is the compiled version fo fbcp, ready for being executed. It will need a litlle bit of extra configuration, but with a good tutorial everyone will be capable of doing it. Thanks!

Ok so I'll looking to add it to recalbox, and I'll let you make a full wiki

Hello hello! I followed your procedure jj and it works but after restart impossible to run again on the screen. So I hacked ... and it's work for the moment... I detected some errors in your tutorial if you write the wiki I can also watch for mistakes.

[cluf20]

when I stop the pi and I restart the screen does not work anymore ... I do not understand where it may come ...

[pinuct]

Yes please!!!, i will make a full wiki happily About my previous "tutorial", it have to have a lot of mistakes XD. I made it from memory and probably the steps are out of order, or worng. But don't worry, if i write the wiki i'll be sure to write the correct steps and test it. About the screen working at restarting, you have to be sure to write in the file  /etc/init.d/S99Custom  the line:

./path_to_your_fcbp_file/fbcp &

That makes autostart the fbcp executable. And remember if you can't save the file after you modify it, try:

mount -o remount,rw /

And the fbcp must be executable:

chmod +x /path_to_your_fcbp_file/fbcp

Thanks!

[cluf20]

Yes thanks I do that! I have always the same problem. I need to restart and that's work.... i don't understand...

Hi @Cluf20, i'm following with my protable Recalbox project and because i need to add controls to it and the gpio joystick included in recalbox uses some pins that are already used by the TFT screen i decided to fork it and chnage a little bit. I modified the code to alow customization of the gpios used in the module, so you can choose the gpios you want. If you are interested you can check it here. I made a pull request to the repository for those people who want to use it in recalbox.

Hi jj, for my project I use a teensy , it allows to be more flexible on the controller . The teensy connects to usb raspberry and after programming is recognized as a Gamepad trade. After you can easily remove and rejouter buttons. IF you are interested I have the program. For the screen , is that you have not forgotten anything in the procedure for it to be recognized after cold reboot ? because each screen reboot is white again as if SPI was more active ? After I have to redo a manipulation to make it work ... search conditions I followed your procedure I remade 5 times lol. I have a doubt against the S99costum contained . In this file you that this line ? If I had my 3D printer I can print the hull !!

hello hello jj, I try to rewrite your procedure , do you tell me if I forget something?I try to rewrite your procedure , do you tell me if I forget something? To see where is my error from your screen that works properly ? Change video mode in recalbox.conf: global.videomode=default Enable the SPI bus of the raspberry pi, to do that, write at the end of /boot/config.txt : mount -o remount,rw / mount -o remount,rw /boot nano /boot/config.txt dtparam=spi=on Add to the file /etc/modules.conf : nano /etc/modules.conf spi-bcm2835 After enabling the SPI you can reboot. After reboot you can enable the TFT by using the comand: modprobe fbtft_device name=pitft To make it launch at boot you have to add to the file /etc/modules.conf : mount -o remount,rw / mount -o remount,rw /boot nano  /etc/modules.conf fbtft_device Create a file under /etc/modprobe.d/fbtft.conf with the next line of code: nano /etc/modprobe.d/fbtft.conf options fbtft_device custom name=pitft width=320 height=480 rotate=90 speed=62000000 fps=60 Alow execution of the file fbcp: chmod +x /usr/fbcp/fbcp To automatically launch fbcp modify the starting scripts under /etc/init.d/: cd /etc/init.d/ ls cp S00Xxxxx S99custom nano S99custom /usr/fbcp/fbcp & /etc/init.d/S99custom start

Hello, I'm going to do a condensed guide for the Adafruit 3.5 inches TFT (I tested other screen, wsaveshare 3.5, and the procedure is a little bit different). Adafruit 3.5: 0. - Note: i don’t know if anyone have this problem, but i read on the forums, and it seem that other people have the same problem. The problem is that when you try to write, you can’t because the file systems is only read. To solve it use:

mount -o remount,rw / mount -o remount,rw /boot

1. - Add to the file /etc/modules.conf

spi-bcm2835 fbtft_device

2, - create a file under /etc/modprobe.d/fbtft.conf with the next line of code:

options fbtft_device custom name=pitft width=320 height=480 rotate=90 speed=62000000 fps=60

3. - Get FBCP, compile it, or copy it. 4. - For autostart, your /etc/init.d/S99custom must look like (is your fbcp file is under /usr/local/bin/fbcp/):

#!/bin/bash ./usr/local/bin/fbcp/fbcp & test -e "/recalbox/share/system/custom.sh" && /recalbox/share/system/custom.sh

5. - Set global.videomode=default in recalbox.conf 6. - Reboot and enjoy   I hope this helps you.

Hello jj, I think you forget some instructions in your last post like SPI activation.

[cluf20]

Hello jj, I need your help, I can not operate the screen more than once ... I do not understand..... Thank you for all

[cluf20]

Bon après un premier essai d'impression j'ai du reprendre le modèle pour une meilleure qualité! Demain, début de l'impression!! Ci-joint le rendu final.

[cluf20]

Hello hello !!! Le projet avance !!! Après quelques difficultés d'impression, quelques photos du premier montage !

[cluf20]

Et une autre photo de l'avant

[rockaddicted]

Prometteur! Good job

Salut, Très beau projet Cluf20 Dit, j'ai un projet similaire et je n'arrive pas à faire démarrer recalbox sur l’écran TFT. Je vois que vous avez pas mal cherché mais je ne suis pas très bon en anglais. Avez vous reussi ? Merci et bonne chance pour la suite

[julius181]

Re Après avoir fait les mêmes manipulations que vous. L’écran fonctionne a merveille à un détail près. L'affichage n'est pas à 100%. Un petite photo pour vous montrer. J'ai bien modifier le fichier /etc/modprobe.d/fbtft.conf en mettant : options fbtft_device custom name=pitft width=320 height=240 rotate=270 speed=80000000 fps=60 au lieu de : options fbtft_device custom name=pitft width=320 height=480 rotate=90 speed=62000000 fps=60 Mais cela ne change rien. Je vais continuer a chercher mais quelqu'un a une idée du probleme ? Merci
