Unable to access GPIO pins
Created by: rajmehta28599
I have a BeagleBone Black board and I'm using the below-mentioned image file. https://debian.beagleboard.org/images/bone-debian-10.3-iot-armhf-2020-04-06-4gb.img.xz
################################### I aim to operate GPIO pins of this board with the c programming language.
To do so, I've gone through this link: https://beagleboard.org/static/librobotcontrol/installation.html
And after following all the steps according to this link the result I achieved is the same as mentioned in the checking functionality step [the last step] of this document.
################################ Furthermore, I follow this document for c language setup: https://github.com/beagleboard/librobotcontrol/blob/master/docs/src/project_template.dox
and run this source code: https://beagleboard.org/static/librobotcontrol/rc_test_leds_8c-example.html
All these processes were completed without any error.
################################## Now I want to access the GPIO pins of the board. For that, I've prepared a basic code.
Let's take a pin P8_10 / GPIO2[4] for an example. So for that my code will be:
#include <stdio.h> #include <rc/led.h> #include <rc/gpio.h> #include <rc/time.h> //#define WAIT_US 500000 // time to light each LED in microseconds int main() { rc_gpio_init(2,4,GPIOHANDLE_REQUEST_OUTPUT); /* declare as output*/ rc_gpio_set_value(2,4,1); /* set high */ rc_gpio_cleanup(2,4); return 0; }
After executing this code I am not getting the expected output.
So have you any suggestions for me regarding this code. Or is there any other way to do so?
Thank you.
