Part Number:AM5748
Tool/software: Linux
Hi all,
We are trying to interface 16x2 LCD display with am5748 processor, The GPIO pins are as below,
GPIO8_13 |
GPIO8_14 |
GPIO8_15 |
GPIO8_19 |
GPIO8_21 |
GPIO8_22 |
GPIO8_23 |
GPIO4_3 |
I am writing a code to drive the 16x2 LCD display and we have some functions in /include/linux/gpio.h for checking a valid GPIO, request and release for a gpio, setting direction and values of the gpio.
can I use this GPIO8_13 pin as a GPIO number for example
gpio_request(GPIO8_13)
gpio_direction_output(GPIO8_13, 1);
gpio_set_value(GPIO8_13, 1)
gpio_free(GPIO8_13)
If the above procedure is not correct kindly update me the correct way of accessing these gpio pins.
Thank You
