My bartop dont stops with crying, but I arrive to install, and activate ssh (what is not activated by default after nov16, beep) Also no cmake inside, but installed also now. And this cmake give me an error,pi@Raspian:~/fbcp-ili9341/build $ cmake -DFREEPLAYTECH_WAVESHARE32B=ON CMake Error: The source directory "/home/pi/fbcp-ili9341/build" does not appear to contain CMakeLists.txt. Sure and after juj description you make mkdir build and after cd build (empty) so he cannot find this file there but a level lower, somebody make a mistake or cmake changed...
Finally I arrive, but errorspi@Raspian:~/fbcp-ili9341/build $ cmake -DFREEPLAYTECH_WAVESHARE32B=ON /home/pi/fbcp-ili9341 -- Doing a Release build -- Board revision: a02082 -- Detected this Pi to be one of: Pi 2B rev. 1.2, 3B, 3B+, CM3 or CM3 lite, with 4 hardware cores and ARMv8-A instruction set CPU. -- Enabling optimization flags that target ARMv8-A instruction set (Pi 2B >= rev. 1.2, 3B, 3B+, CM3 or CM3 lite) -- Scaling source image to view.

Ok, I understand, he wanted one more parameter, not easy to read between lines. So he build something, must just find itpi@Raspian:~/fbcp-ili9341/build $ cmake -DFREEPLAYTECH_WAVESHARE32B=ON -DSPI_BUS_CLOCK_DIVISOR=8 /home/pi/fbcp-ili9341 -- Doing a Release build -- Board revision: a02082 -- Detected this Pi to be one of: Pi 2B rev. 1.2, 3B, 3B+, CM3 or CM3 lite, with 4 hardware cores and ARMv8-A instruction set CPU. -- Enabling optimization flags that target ARMv8-A instruction set (Pi 2B >= rev. 1.2, 3B, 3B+, CM3 or CM3 lite) -- Scaling source image to view.

@Substring
Ok, I have an executable, now somebody must tell me where is equivalent to rc.local in Recalbox ? -
@dragu no such files. Startup scripts are in /etc/init.d. create a S02iliblabla, get the basic structure of an init file, and launch it at start.
But first, you'd better try by launching it manually through ssh and make sure it works. If ypu just write an init script, you'll never get any ettor message

@Substring
Petite question, pour recompiler, vaut-il mieux d'effacer le contenu du build précédent ?Bonne idée de le lancer en ssh. Bon, il affiche rien pour le moment, mais me sort tout un tas de messages sophistiqués

Ok, I also found this cmake option
"-DDMA_RX_CHANNEL=<num>: Specifies the DMA channel number to use for SPI receive commands. Change this if you find a DMA channel conflict."
What would you propose, Master ? -
Yes, we can. I used DMA channel 4 for RX, and the result
I will try to stretch a little the sides if possible, but already very nice
-
@dragu To recompile, the best is to
make clean
Regarding the values, the best is probably to ask Flavor
-
@Substring
I was more brutal using rm -r
But @Flavor dont use fbcp-ili9341, there is even no word about in the forum. Anyway, I am near the end with this one also. Pretty well working all this with standard Recalbox and just small addons. When I am finished with scaling here, there is just staying one point to close the thread. -
Vive la France, so I hope everybody recuperate for tomorrow....
Ok, concerning fbcp-ili9341, I am finished and adjust now the TFT screen to the viewport matching the physical window in the GBA shell. After 2 dozens of recompilations, and I have a version for all other people that will buy this kit. As you can see in the fotos, this fit. That they are round is fault of the lens.So this story also over.
Now only thing what stays is the software for the brightness controller of the display background.

But with the automatic starting I will need some help.
I tried first to put it in custom.sh to not meddle in the Recalbox system, my driver in
/recalbox/share/system/fbcp-ili9341/fbcp-ili9341
custom.sh :#!/bin/bash start() { /recalbox/share/system/fbcp-ili9341/fbcp-ili9341 & } stop() { } case "$1" in start) start ;; stop) stop ;; esac after no effect, I added fbcp-ili4391 to /usr/bin/fbcp-ili9341 and replaced start line with ./fbcp-ili9341 &
again no result
After this I created S02fbcp-ili9341 inside /etc/init.d#!/bin/bash /recalbox/share/system/fbcp-ili9341/fbcp-ili9341 & esac exit $? and also with ./fbcp-ili9341 &
Both fbcp-ili9341 have the flag 755Not working. What is my error ?
-
@dragu Make sur your binary is in /usr/bin + also make sure it has executable rights. Then simply create a /etc/init.d/S02ili9341
which should hold:#!/bin/bash #!/bin/bash start() { /usr/bin/fbcp-ili9341 & } stop() { } case "$1" in start) start ;; stop) stop ;; esac You should use an absolute path to the file. Easy way to test it : in SSH, just run
/etc/init.d/S02ili9341 start
and tell us about the outputThe next good idea would be to daemonize the fbcp thing, but that's absolutely not mandatory
-
@Dragu S02fbcp-ili9341 seems to be e bit early to try to start fbcp... you should try S13 after S12populateshare
-
@Substring
@ian57
The script give me an error with ...... start/etc/init.d/S02fbcp-ili9341: line 10: syntax error near unexpected token `}' line 10 is just the closing accolade for stop (because no content ?)
} stop() { } -
@dragu ah yeah indeed. Just add a
echo -n ""
-
@Substring
@ian57
Yes, echo -n"" helped Starting in ssh was ok, but not as S02.... in /etc/init.d
So, I put the lines into custom.sh started automatic by S99custom. And it works just after the loading screen. So takes some time. Do you think it could be loaded before splash screen, or not possible ? -
@dragu as ian said, and i forgot about it : the usual fbcp is started rather late (somewhere in S13) most probably due to device setup time. So rename it to S13blabla
-
@Substring
@ian57
Ok, guys, thanks alot. S13... was the solution. So, I will not bother you anymore,till tomorrow
- about a year later

Bonjour étant extrêmement nul en anglais serait-il possible de savoir ou en est la possibilité de faire fonctionner un freeplay avec recalbox ?? Est ce ça mise en œuvre est compliqué et faut il que je me tourne vers retropie ???
