1、esp32的GPIO都由官方集成了相应的函数。主要配置函数为gpio_config();设置的结构体为: gpio_config_t io_conf = { //打开IO下下降沿中断 io_conf.intr_type = GPIO_INTR_NEGEDGE, //设置io输入输出模式 io_conf.mode = GPIO_MODE_INPUT, //选择GOIO io_conf.pin_bit_mask = 1ULL<<GPIO_NUM_9...

1. gpio口配置函数 esp_err_t gpio_config(const gpio_config_t *pGPIOConfig)端口可以设置以下模式：pull-upPullDownIntrType参数： pGPIOConfig结构体返回： ERP_OK或ESP_ERR_INVALID_ARG gpio_config_t 结构体 使用示例：gpio_set_pull_mode(3, GPIO_PULLUP_ONLY); gpio_set_pull_mode(4, GPIO_PULL...
首先,通过`gpio_config`函数配置GPIO口,`gpio_config_t`结构体定义了端口的配置信息。例如:`esp_err_t gpio_config(const gpio_config_t *pGPIOConfig)`。接下来,`gpio_reset_pin(gpio_num_t gpio_num)`用于复位指定的GPIO引脚。要设置GPIO引脚的方向,使用`gpio_set_direction(gpio_num_t gp ...

to a gpio_config_t variable, specifically stating that I want a PULLUP on an Output pin, AND AND, having an external pull up resistor 1K (for good measure in case the pin does not have a pull-up), when the call is made to the gpio_config(&io_conf) the pin goes immediately LOW...
