官方的烧录方式是idf.py flash -b 921600 -p /dev/ttyUSB0 monitor,/dev/ttyUSB0是Linux下的端口,Windows下格式为idf.py flash -b 921600 -p COMX monitor,X为端口号,921600是波特率,按照这个波特率可能后面无法通信(idf SDK Configuration Editor中搜索baud rate,可以修改波特率),建议直接使用idf自带的烧录选项...
gpio_config() Alternatively where can I found a description and of course the need to use various gpio_pad_xx() functions. Thanks in advance RobertESP_Sprite Posts: 10052 Joined: Thu Nov 26, 2015 4:08 am Re: ESP32 GPIO Configuration (gpio_pad_select_gpio)Quote...
I'm using ESP32C6 module for our application. Due to IO pin constrain I want to use GPIO 8(strapping pin) as IO for led toggle while running application. After module reset, in main I do below gpio configuration, gpio_config_t io_conf = {}; ...
2、LRCLK:选择左右声道用的。就是上面代码 gpio_cfg 的 ws 成员,叫法不一样罢了。 3、BCLK:位时钟线,就是每个跳变周期你得发送/接收一个二进制位,这个好懂吧,就跟 i2c 的 SCL 差不多。 4、DATA:可能一根线,可能两根线(输入/输出)。就是传数据用的。

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_…
