ESP_ERROR_CHECK(esp_bt_controller_mem_release(ESP_BT_MODE_CLASSIC_BT)); 1. 3、按照默认配置BT_CONTROLLER_INIT_CONFIG_DEFAULT,初始化 蓝牙控制器: esp_bt_controller_config_t bt_cfg = BT_CONTROLLER_INIT_CONFIG_DEFAULT(); //初始化
The ESP32 LED PWM controller has 16 independent channels that can be configured to generate PWM signals with different properties. All pins that can act as outputs can be used as PWM pins (Input only pin GPIOs 34 to 39 can’t generate PWM). To set a PWM signal, you need to define t...

4 PWM interfaces; 1 IIC controller; 1 low speed SPI interface; 2 LED indicator lights; 1 BOOT button; 1 reset button Features: **Versatile Connectivity and Performance** The ESP32 Development Board is a versatile tool for developers looking to integrate WiFi and Bluetooth connectivity into their...
ESP32 contains two I2S serial communication peripherals. I2S is used for Audio transmission and reception between two Audino devices. Each I2S controller works in a half-duplex communication mode. But we can combine these two available controllers to achieve full-duplex communication. ...
idf版本:esp-idf_v5.02 项目需求:esp32开发板作为hfp-ag网关,与蓝牙耳机连接,通过es8311连接有线麦克风与扬声器,对着有线麦克风呼叫的话音数据能传输到蓝牙耳机;对着蓝牙耳机上的麦克风呼叫的话音数据能传输到有线扬声器,实现类似于蓝牙对讲机的效果。 目前遇到的问题: 1.我是用hfp_ag的hci模式时,无论是蓝牙回调...
The c3 datasheet, Section 3.4.9 USB Serial/JTAG Controller seems promising, but I don't see details on how to use it. I would love some advice and/or pointers to documents that explain how to use these two pins via the USB. Thank you....
本案例程序是演示GPIO中断接口的基本使用,案例操作结果是通过按键切换开发板上的LED的点亮和熄灭效果。 本案例使用的按键根据开发板原理图可以得到,接入的是GPIO5号引脚。所以本次开发驱动的GPIO引脚是GPIO5。 按键和LED灯在开发板的位置如下图红色框框标记所示,按键在上,LED灯在下: ...
接下来,我们需要编写一段MicroPython代码,让ESP32控制LED灯的亮灭。具体步骤如下: 1.打开Thonny软件。 2.在“文件”菜单中选择“新建”,然后输入以下代码: machine 是大模块,Pin 是 machine 下面的其中一个小模块,在 python编程里有两种方式引用相关模块: ...
