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_…
gpio_config_tio_conf = {};// 禁用中断io_conf.intr_type = GPIO_INTR_DISABLE;// 设置为输出模式io_conf.mode = GPIO_MODE_OUTPUT;// 要设置的引脚的位掩码,例如GPIO18/19io_conf.pin_bit_mask = GPIO_OUTPUT_PIN_SEL;// 禁用下拉模式io_conf.pull_down_en =0;// 禁用上拉模式io_conf.pull_u...

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...
Pin.init(mode=-1, pull=-1, *, value, drive, alt)重新初始化GPIO口; Pin.value([x])不填写参数使用时返回端口的值,参数填写0(False)、1(True)改变端口值; Pin.on()输出或开漏模式下将端口设置为高; Pin.off()输出或开漏模式下将端口设置为低; ...
