How to use Rpi’s GPIO? #2916

Closed eziologico closed 4 years ago

eziologico commented 4 years ago

Someone can tell me what is the syntax in printer.cfg file to use the Raspberry Pi GPIO pins and the available options? I didn't found any documentation.

Thanks

Hi @eziologico,

It did not look like there was a Klipper log file attached to this ticket. The log file has been engineered to answer common questions the Klipper developers have about the software and its environment (software version, hardware type, configuration, event timing, and hundreds of other questions).

Unfortunately, too many people have opened tickets without providing the log. That consumes developer time; time that would be better spent enhancing the software. If this ticket references an event that has occurred while running the software then the Klipper log must be attached to this ticket. Otherwise, this ticket will be automatically closed in a few days.

For information on obtaining the Klipper log file see: https://github.com/KevinOConnor/klipper/blob/master/docs/Contact.md

The log can still be attached to this ticket - just add a comment and attach the log to that comment.

Best regards, ~ Your friendly GitIssueBot

Are you wanting to use them for serial communication or for like fans and thermistors and such?

eziologico commented 4 years ago

Hi @mental405 , Not for serial communication, for switch on-off light or whatever. I would like to use the local GPIO from RPi where klipper is running. I found some posts about it but it's no clear how to do it.

Thanks

dianlight commented 4 years ago

You need to build/install and start the klipper_mcu and use it in config as secondary mcu. The startup scripts are in PR #2781

In prnter.cfg add

[mcu host]
serial: /tmp/klipper_host_mcu

and then you can use the pins or bus like:

[output_pin caselight]
pin: host:P20 

[temperature_sensor enclosure_temp]
sensor_type: HTU21D
i2c_mcu: host
i2c_bus: i2c.1
htu21d_hold_master: False

Hi @dianlight , Thank you for your reply. I think, in first, I must create the klipper.elf file. I tried to make a "linux process" firmware but I get an error:

I upgraded klipper to the latest git version.

One question: does klipper process still run if the printerboard is offline in order to use a RPi Gpio pin to turn on-off the printer with the M80/M81 gcode?

Thank you for your help,

Ezio

dianlight commented 4 years ago

It appears that it did not correctly save the .config file. Try to reconfig with menuconfig or nconfig target.

Can you post it?

For M80 / M81 question the current klippy architecture does not allow to command one MCU if the other is in error or in shutdown. So for now you can't have an MCU that controls the other's power switch.

eziologico commented 4 years ago

Ok, a "make clean" fixed it. So the linux firmware is running in /usr/local/bin/klipper_mcu with your start script in /etc/init.d and the /tmp/klipper_host_mcu virtual printer is present.

adding the second mcu in printer.cfg klipper is still running

[mcu host]
serial: /tmp/klipper_host_mcu

if I define the pin it stops working

[output_pin caselight]
pin: host:P20

MCU 'host' shutdown: Unable to open out GPIO chip line

The GPIO is already used by another process or no gpiochip is found.

You are on an OrangePi right? I don't know the chipset.

For the gpiochip:

Try gpiodetect command and post the result. The klipper implementation use only the gpiochip0

For the process:

Use the gpioinfo command or try ls /sys/class/gpio/and see if the gpio is exported.

Remember you can't use another process like an Octoprint plugin to command the same GPIO pin.

eziologico commented 4 years ago

Hi @dianlight , To speed up a little bit and to be sure there are not other unwanted process running, I abandoned the OrangePi and did a fresh installation of Raspbian Buster Lite and Klipper on a Raspberry Pi 2 model B. Using the scripts from your Klipper Fork, I have now the Linux process up and running but Klipper is unable to open the virtual printer /tmp/klipper_host_mcu due to "Permission denied".

eziologico commented 4 years ago

Hi @dianlight , So the problem is in the /tmp/klipper_host_mcu link that is not owned by pi user but by root and the pi user is not in tty group by default. As I don't know how to change the link I added the pi user to tty group and it works now.

groups pi
pi : pi adm dialout cdrom sudo audio video plugdev games users input netdev spi i2c gpio

sudo adduser pi tty

It would be nice to have a script like "install-beaglebone.sh" to install everything. Maybe there is already one but is not documented.

For gpioinfo command I installed gpiod package. I'm using pin 26 as output for test

sudo apt install gpiod

Can I use some pins in Linux environment for WebIOPi and others in Klipper?

Thank you for your help and your great work,

dianlight commented 4 years ago

Thanks for reporting the error on ./scripts/flash-linux.sh (I proceed to the correction as soon as possible). In reality the use case would be the use through make flash.

Being klipper_host_mcu -> /dev/pts/2 a link you have to heal the permissions of /dev/pts/2. it Is correct that pi is in the tty group. Usually the addition to the group is done directly by the octoprint installation script so it is not documented ... maybe it should.

A pin can be used by one and only one process. So you can use any unused pins. But beware of programs that use libraries such as wiringpi that do not "reserve" the pin on the kernel so see the pin as not used.

If you are using my branch, manage the second mcu with the parameter MCU=2 so as not to redo the configuration every time. So you can do:

#main mcu
make menuconfig  #only the first time
make
make flash

#mcu secondary
make MCU = 2 menuconfig #only the first time
make MCU = 2
make flash

Last thing if you give me the output of sudo gpiodetect e sudo gpioinfo on OrangePi I can understand why it doesn't work and maybe send a correction PR.

L.

eziologico commented 4 years ago

Hi @dianlight This is the output of the OrangePi Zero Plus H5. I made a lot of test trying to manage the GPIOs from remote but without success, so i thing this system is not more reliable. I can try again in another OrangePi Zero H2 that is more clean, if you want.

Hi @dianlight , I installed it on the OrangePi Zero H2+ too, and it works!

The pinout is different from RPi

The problem on " OrangePi Zero Plus H5" is the sequence of gpiochip. Actual implementation use only the gpiochip0 and for the "Opi ZP H5" the right is gpiochip1.

If you are interested and you can test for me I can create a PR to use the other chips too.

Yes, I can install armbian from scratch on the OrangePi Zero Plus H5 and test it for you.

If you prefer you can send me a PM,

Ezio

I release a very preliminary version of the patch at dianlight/klipper.

NOTE: The pin numbers now are declared as P<chipId>_<pinId> so your old P20 become P0_20.

For "Opi ZP H5" where the gpiochip1 need to be use, you can now assign P1_<gpio> as you can see on gpioinfo output.

I'm waiting for your feedback to clean up the code to propose an official PR.

Hi @dianlight I just installed your branch on a fresh OrangePi Zero plus H5 but it doesn't accept the pin number as you mentioned:

git clone --single-branch --branch linux_gpio_morechip https://github.com/dianlight/klipper.git

Unknown value 'P1_2' in enumeration 'pin'
This type of error is frequently caused by running an older
version of the firmware on the micro-controller (fix by
recompiling and flashing the firmware).
Once the underlying issue is corrected, use the "RESTART"
command to reload the config and restart the host software.

I tried P1.2 instead of P1_2 (looking at your code) and it's accepted but it use always the same pin on gpiochip0 pin0, even declaring different pin number.

Hi @eziologico , Sorry, after writing the instructions I made a refactor to bring the names of the pins back to the standard.

I did another push on the branch where I should have corrected the problem (if you can do another test I would be grateful) and I optimized the code a bit.

Also do a make oldconfig I changed the make scritpts a bit.

hi @dianlight , I fetched the new version and declared 2 gpiochips in the linux-firmware as the available gpio pins are on chip1 on this board, anyway the gpiodetect and gpioinfo commands are not installed by default, so it's not so easy to know which chip is the right one. I don't have any /dev/gpiochip* device in armbian like in raspios, maybe somthing in your script doesn't work as expected. I tested all the available pins an they works (P1.0 to P1.20 and P1.198 - P1.199), even with a Led on random outputs switching it on/off. Even declating some P0.0... pins on chip0 seems working but as they aren't available I don't care it.

At the moment the configuration is not so user frendly, can it be improved?

hi @eziologico , summarizing is now going but configuration is a nightmare? ;)

...anyway the gpiodetect and gpioinfo commands are not installed by default, so it's not so easy to know which chip is the right one. ...

Did you use the install-debian.sh script?

The kernel interface allows control of the gpio chips as these are electrically connected and which pins are exposed depends on the vendor and the pcb design (in some cases also on the pcb version). Many libraries have pre-designed configurations for the most common boards but it would not be logical for a project like klipper.

What you can do is add the config examples for the various boards with the pins exposed to the documentation exactly as it is done for the mcu. ( Kevin allowing volunteers to be accepted;) )

... I don't have any /dev/gpiochip* device in armbian like in raspios, maybe somthing in your script doesn't work as expected. ...

/dev/gpiochip* is the character device that is also opened by the mcu therefore it is very strange that it does not exist. The system configuration probably loads the kernel module of the gpio chips only when someone tries to access it. Try doing an ls /dev/gpiochip* after the MCU has started and you've tested at least one pin or after a gpioinfo

If the devices are there you can try after a reboot when they do not appear in /dev to run the command sudo stat /dev/gpiochip0 and see if they appear or if only the 0 appears.

Hi @dianlight , So it seems working now. :)

Did you use the install-debian.sh script?

No, I always use install-octopi.sh as in the Klipper documentetion and flash-linux.sh to install the linux firmware. I don't know what the other scripts are for. Should I use install-debian.sh script?

Try doing an ls /dev/gpiochip* after the MCU has started and you've tested at least one pin or after a gpioinfo

I checked it again and they appear now, I don't know why it wasn't before.

pi@test-gpio:~$ ls -la /dev/gpiochip*

I'm going to close this as it looks like a solution was found for the original issue.
