adding lua periphery library

Post by Neb » Mon May 11, 2020 9:17 am

Hello everyone !

So my project is to use our beloved LÖVE using as Raspberry Pi and Retroppie, and for the moment it has been a success :-)
Now I'm trying to use the pins of the raspberry pi with the lua-periphery

I got the .zip file, extracted it next to my main.lua

then in my love.load() :

Code: Select all

local GPIO = require('periphery').GPIO

    local gpio_out = GPIO("/dev/gpiochip0", 17, "out")
I'm developping on Win 10, and I understand that this library is linux based, so I'm aware that I should see some errors pop-up, but heres what I've got from the errors messages :

main.lua:5: module 'periphery' not found:
no field package.preload['periphery']
no 'periphery' in LOVE game directories.
no file 'periphery' in LOVE paths.
no file '.\periphery.lua'
no file 'C:\Program Files\Love\lua\periphery.lua'
no file 'C:\Program Files\Love\lua\periphery\init.lua'
no file '.\periphery.dll'
no file 'C:\Program Files\Love\periphery.dll'
no file 'C:\Program Files\Love\loadall.dll'


[C]: in function 'require'
main.lua:5: in function 'load'
[C]: in function 'xpcall'
[C]: in function 'xpcall'
What I understand is that LÖVE don't find the module.
I've seen this this bits on the github documentation but I don't really understand it, and don't know if I have something to do in Windows to make it work :
Build and install from source

Clone lua-periphery recursively to also fetch c-periphery, which lua-periphery is built on.

$ git clone --recursive
$ cd lua-periphery
$ make clean all
$ cp /path/to/lua/libs/

Place in a directory searched by the Lua package.cpath variable. For example: /usr/lib/lua/5.3/, the same directory as other Lua sources, etc.

lua-periphery can then be loaded in lua with periphery = require('periphery').
Any idea of what I should do ?

Thanx !

You basically can't do this on Windows. You need to compile the C module on Linux and do other Linuxy things to get it working. This also seems to be built for Lua 5.3 and may no tbe compatible with LOVE (LuaJIT aka Lua 5.1 + some other stuff).

Alright ! Thank you for the tip ! Not a good news for me hehe

I managed to find someone who did a "Lua for Windows" installer (wich apparently run Lua5.1) with Luarocks library 2.0.2 on github, I'll try this solution.
And here's what the Github pages say for the lua-periphery module :
lua-periphery is compatible with Lua 5.1 (including LuaJIT), Lua 5.2, and Lua 5.3
I'll see if it works that way !
