still error

jyijyi · January 13, 2022, 9:43am

can you see if you can control the GPIO13?

root@swi-mdm9x28-wp:~# echo 13 > /sys/class/gpio/export
-sh: echo: write error: Device or resource busy
root@swi-mdm9x28-wp:~#

tanaporn_y · January 13, 2022, 9:50am

yes. I can control by used command above

jyijyi · January 13, 2022, 9:52am

I don’t see any error in your logread

tanaporn_y · January 13, 2022, 9:56am

it doesn’t have an error but the program not working while read gpio13 line
it should read gpio13 after gpio7 but it not.

jyijyi · January 13, 2022, 9:59am

how about my application?
Do you see the GPIO13 changing state?

tanaporn_y · January 13, 2022, 10:00am

yes. I got this

Then why i don’t see
LE_INFO("Pin21 read PP - High: ");
LE_INFO("Pin21 read PP - Low: ");

tanaporn_y · January 13, 2022, 10:10am

the program is stop before that line

legato program cannot open handler function. I have to use app stop tp
how can I fixed it??

this is not about GPIO13…
Are you using my app?

tanaporn_y · January 14, 2022, 9:29am

can you check it for me??
sandboxed : false

adef:
executables:
{
gpio = ( gpioComponent )
}

bindings:
{
gpio.gpioComponent.le_gpioPin7 → gpioService.le_gpioPin7
gpio.gpioComponent.le_gpioPin8 → gpioService.le_gpioPin8
gpio.gpioComponent.le_gpioPin13 → gpioService.le_gpioPin13
gpio.gpioComponent.le_gpioPin23 → gpioService.le_gpioPin23
gpio.gpioComponent.le_gpioPin25 → gpioService.le_gpioPin25
gpio.gpioComponent.le_gpioPin42 → gpioService.le_gpioPin42
}

processes:
{
/*envVars:
{

LE_LOG_LEVEL = DEBUG
}*/

run:
{
    ( gpio )
}

}

#include “legato.h”
#include “interfaces.h”

COMPONENT_INIT
{
LE_INFO(“Pin13 read PP - High: %d”, le_gpioPin13_Read());

}

why don’t you try my app first?
It is more simple that just one GPIO is used.

tanaporn_y · January 14, 2022, 9:46am

I already tried it was the same result
