local uart_ID = 1--用来方便改串口号,需要用串口2,改成2就行 local setGpio4 = pins.setup(4, 0)--设置GPIO 4为输出,默认低电平 local function read_hd()--接收处理函数 local data = ""--定义一个字符串变量,用来存放串口读取的数据 while true do data = uart.read(uart_ID, "*s") if not...
假设ESP32-C3的printf 的串口为UART_1 ESP32-C3新配置的串口为 UART_2 5.功能实现 电脑通过串口UART_2发送数据到ESP32-C3 ESP32-C3 使用printf 函数 通过UART1打印给电脑 printf (“%s\n”, data); 并且通过串口打印到电脑的串口,即可在串口调试小助手上接收 uart_write_bytes(ECHO_UART_PORT_NUM,(const...
ESP32-C3 系列芯片支持可信启动、flash 加密、安全存储等多种安全功能,还有专用外设来支持 HMAC 和数字签名等用例。这些功能所需的私钥和配置大多存储在 ESP32-C3 的 eFuse 存储器中。 启用安全功能时需要谨慎,因为使用到的 eFuse 存储器是一次性可编程存储器,烧写过程不可逆,安全功能最好先在试验场(比如模拟器...
HardwareSerial SerialPort(2); // use UART2 void setup() { SerialPort.begin(15200, SERIAL_8N1, 16, 17); } If using UART1, we will initialize it as follows: An important point to note here is that GPIO pin 9 and pin 10 which are part of UART1 TX and RX pins, are internally co...
- "uart_set_pin(UART_NUM_0, UART_PIN_NO_CHANGE, UART_PIN_NO_CHANGE, UART_PIN_NO_CHANGE, UART_PIN_NO_CHANGE)" - by doing this, you are telling the board to use defaults, which will default to D+ and D- pins (on the USB) -- correct me please if my understanding on this par...

The debug output I got is from pin 21 which is UART0 Tx.Collaborator SuGlider commented Dec 27, 2024 • edited ESP32C3 Dev Module has a CH340 that is used to convert UART to USB-CDC. I can use both pins 20/21 of the UART0 and 19/18 of the JTAG/USB-CDC port, by selecting...
In this tutorial, we will explore the pinout of the XIAO ESP32S3 and its related board, the XIAO ESP32S3 Sense, and learn how to use these pins for different purposes. Specifically, we will cover the usage of 1x UART, 1x lIC, 1x lIS, 1x SPI, 11x GPIOs (PWM), 9xADC, 1x ...
