Hello Everyone,
When I debug the GPIO interrupt of nrf5340, the edge trigger can be normal, but it will be triggered all the time when the level is triggered. Does anyone have this problem？Below is my config and some code:
prj.conf
CONFIG_GPIO=y # Config logger CONFIG_LOG=y CONFIG_USE_SEGGER_RTT=y CONFIG_LOG_BACKEND_RTT=n CONFIG_LOG_BACKEND_UART=y
main.c
#include <zephyr.h>
#include <sys/printk.h>
#include <drivers/gpio.h>
#define BT_PORT "GPIO_0"
#define BUTTON_1 23
#define BUTTON_2 24
const struct device *gpio_0;
void button_pressed(const struct device *dev, struct gpio_callback *cb,
uint32_t pins)
{
if (pins & BIT(BUTTON_1))
{
printk("Button1 is pressed!\n");
}
else if (pins & BIT(BUTTON_2))
{
printk("Button2 is pressed!\n");
}
}
static void configure_button(void)
{
int ret;
static struct gpio_callback button_cb;
gpio_0 = device_get_binding(BT_PORT);
gpio_pin_configure(gpio_0, BUTTON_1, GPIO_INPUT | GPIO_PULL_UP);
gpio_pin_configure(gpio_0, BUTTON_2, GPIO_INPUT | GPIO_PULL_UP);
ret = gpio_pin_interrupt_configure(gpio_0, BUTTON_1, GPIO_INT_LEVEL_LOW);
if (ret != 0)
{
printk("Error %d: failed to configure interrupt pin %d\n" , ret, BUTTON_1);
return;
}
ret = gpio_pin_interrupt_configure(gpio_0, BUTTON_2, GPIO_INT_LEVEL_LOW);
if (ret != 0)
{
printk("Error %d: failed to configure interrupt pin %d\n" , ret, BUTTON_2);
return;
}
gpio_init_callback(&button_cb, button_pressed,
BIT(BUTTON_1) |
BIT(BUTTON_2) );
gpio_add_callback(gpio_0, &button_cb);
printk("button init ok\n");
}
void main(void)
{
gpio_0 = device_get_binding(BT_PORT);
if (gpio_0 == NULL)
{
printk("Error: didn't find device port_0\n");
return;
}
configure_button();
while(1)
{
k_msleep(20000);
}
}
Best regards
Pany
