如何修复 ESP-IDF 错误:GPIO isr service is not installed

问题

你尝试使用 ESP-IDF GPIO 中断 API,但你的 ESP 循环崩溃并显示以下错误消息:

gpio_isr_error_log.txt
E (374) gpio: gpio_isr_handler_add(527): GPIO isr service is not installed, call gpio_install_isr_service() first
ESP_ERROR_CHECK failed: esp_err_t 0x103 (ESP_ERR_INVALID_STATE) at 0x400d1584
file: "src/main.cpp" line 478
func: void app_main()
expression: gpio_isr_handler_add(rx_config.gpio_num, onDALIReceive, (void*)0 )

abort() was called at PC 0x40086117 on core 0

解决方案

你需要在调用 gpio_isr_handler_add() 之前调用 gpio_install_isr_service()

这是一个示例:

gpio_install_isr_service.cpp
#include <driver/gpio.h>

void app_main() {
    ESP_ERROR_CHECK(gpio_install_isr_service(0 /* No flags */));
    // Now you can add your GPIO interrupt handlers
    // ...
    ESP_ERROR_CHECK(gpio_isr_handler_add(GPIO_NUM_2, myGPIOInterrupt, nullptr));
}

注意,调用 gpio_install_isr_service() 与使用 gpio_set_intr_type() 函数根本不兼容。所以你不能在同一项目中同时使用两者。
