RPI3 how can I test the GPIO pins is working or dead?

[artiny]

Hello

I want to test GPIO pins is still working or burned out ... is existing function for the test in bash, or how can I determinate is working...

[joan]

wiringPi has the pintest utility.

My pigpio has the gpiotest utility.

Both check the basic GPIO functionality. It's best if nothing is connected to the expansion header during the tests.

[artiny]

The wiringpi test is not only for old RPI 1 ?
I tried and this was output (nothing connected only HDMI, and 1 usb for keyboard)

The second, gpiotest - I first installed the library, and I started with sudo pigpiod , after I launched the gpiotest script, but in console is writed

Testing ....

and after second is closed the terminal windows, ....so I cant see the result beacuse is automatically close after 1 second,when start the Testing

You are the second person to mention my gpiotest fails on a Pi3.

Unfortunately it works okay for me.

Code: Select all

$ sudo pigpiod
$ ls
gpiotest
$ ls -l
total 4
-rwxr-xr-x 1 joan joan 2420 Apr 13 15:19 gpiotest
$ ./gpiotest  
This program checks the Pi's (user) gpios.

The program reads and writes all the gpios.  Make sure NOTHING
is connected to the gpios during this test.

The program uses the pigpio daemon which must be running.

To start the daemon use the command sudo pigpiod.

Press the ENTER key to continue or ctrl-C to abort...

Testing...
Write 0 to gpio 14 failed.
Pull down on gpio 14 failed.
Skipped non-user gpios: 0 1 28 29 30 31 
Tested user gpios: 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 
Failed user gpios: 14 

You can see from the above I have managed to kill GPIO 14.

See if this works. It is a more destructive test and you will need to reboot afterwards.

Cut & paste the following command (assumes you have already done sudo pigpiod).

for ((i=0;i<32;i++)); do echo "testing GPIO $i";pigs w $i 0 r $i w $i 1 r $i m $i r pud $i u r $i pud $i d r $i; done

Mine creates the following output on a Pi3.

You should get the same apart from GPIO14 which should look like GPIO15.

Okay, I am the third one.
I am running my RPi3 on latest Jessie 4-10. terminal command gpiotest tells me no such command. sudo pigiod nothing. Take it slowly, How do I install the library ? Then step by step instruction, please. How do I proceed ?

Appreciate your understanding...

sudo pigpiod not pigiod.  It launches the daemon silently.

If [b]pigpiod -v[/b] says command not found then on Raspbian do

[b]sudo apt-get install pigpio[/b]

If [b]pigpiod -v[/b] returns a number it is installed.

You can test by running the command [b]pigs hwver[/b] which should return 10494082 on a Pi3.

To install pigpio, if it isn't already install in Raspbian, do:

Code: Select all

sudo apt-get update
sudo apt-get install pigpio

I have done all according to above ...

So, everything seems to be in order, except gpiotest NOT running. I am outof juice, what's next ? I need your advice.

Thanks

You need to download the test script and unzip it in your directory.

http://abyz.co.uk/rpi/pigpio/code/gpiotest.zip

From the Pi you could enter the following download and unzip commands

wget abyz.co.uk/rpi/pigpio/code/gpiotest.zip
unzip gpiotest.zip

Ok, done all that.

I can see there is the gpiotest file. Looking into the file and howto proceed looks ok. So I do sudo pigpiod.. then running from terminal doesnt work. Next trying to run from GUI lxterminal it looks better like the test is started but I never get any response. I think I'm doing something stupid/wrong, please advice how I should run the gpiotest ?
Thanks again

I just run it from a command terminal.
