Manually editing the gpio_maps in mk_arcade_joystick_rpi.c did help.
i solved gpio controller not change. here my github : https://github.com/rasplay/mk_arcade_joystick_rpi
So did you actually change something to make it work? All I can find is a version change and some readme updates. mk_arcade_joystick_rpi.c is identical to upstream as far as I can tell (which I used).
our post is write can source chage and recompile mk_arcade_joystick_rpi.c file.
// Map of the gpios : up, down, left, right, start, select, a, b, tr, y, x, tl
static const int mk_arcade_gpio_maps[] = {4, 17, 27, 22, 10, 9, 25, 24, 23, 18, 15, 14 };
// 2nd joystick on the b+ GPIOS up, down, left, right, start, select, a, b, tr, y, x, tl
static const int mk_arcade_gpio_maps_bplus[] = {11, 5, 6, 13, 19, 26, 21, 20, 16, 12, 7, 8 };
// Map of the mcp23017 on GPIOA up, down, left, right, start, select
static const int mk_arcade_gpioa_maps[] = {0, 1, 2, 3, 4, 5 };
// Map of the mcp23017 on GPIOB a, b, tr, y, x, tl
static const int mk_arcade_gpiob_maps[] = {0, 1, 2, 3, 4, 5 };
// Map joystick on the b+ GPIOS with TFT up, down, left, right, start, select, a, b, tr, y, x, tl
static const int mk_arcade_gpio_maps_tft[] = {21, 13, 26, 19, 5, 6, 22, 4, 20, 17, 27, 16 };
if, you want to anyone kind of raspberrypi gpio.
and can recompile file after change gpio remapping.
ours not chage recalbox team source. but write it that how to recompile recalbox team mk_arcade_joystick_rpi.c file.
In that case you did the same as I did as I mentioned earlier: editing the gpio_maps in mk_arcade_joystick_rpi.c (and compiling). I was hoping to be able remap without changing the code and recompiling (using map=5 gpio=pin_nr etc), but that did not work.
ours recompile 0.1.6 ver thought 0.1.4 ver. and raspberrypi gpio test finished. finally, success gpio remapping on the retropie 3.8.1 and 4.0 beta ours are not change /etc/modules/mk_arcade_joystick_rpi config.
our post had been written little bit different on the recalbox github contents.
and how to typing /etc/modules/mk_arcade_joystick_rpi file into contents ?
Custom gpio pins no longer working?
I can no longer get my gpio based joystick to work properly. It used to work fine (after reassigning buttons) with my retropie installation on a RPI2, but in later releases it fails. Not sure if it is related to a more recent kernel. The issue is the same on recallbox.
The gpio pins I use are custom. Running a python test program tells me the arcade joystick still reacts fine on the expected pins.
Loading the kernel module (sudo modprobe mk_arcade_joystick_rpi map=1) and running jstest on js0 makes it recognize the directions, but only 2 of the 8 buttons. Trying to define custom gpio pins (sudo modprobe mk_arcade_joystick_rpi map=5 gpio=pin_nr,..) results in not a single move or button is recognized using jstest.
My gpio config:
Can't recall I did something extra in the past to make it work. Tested with the latest Retropie (v3.8.1) and recalboxOS (4.0.0-beta3).
