FireBeetle 2 ESP32 C6开发板_串口测试_板子上的虚拟串口不能用吗？
本帖最后由 尹小舟 于 2024-4-30 18:27 编辑<p>1 板子上的串口是虚拟串口</p>
<p> </p>
<p>板子没有串口芯片</p>
<p>2.测试代码</p>
<pre>
<code>#include <Arduino.h>
#define LED_BLUE SCK
#define LED_RED MOSI
// the setup function runs once when you press reset or power the board
void setup() {
// initialize digital pin LED_BUILTIN as an output.
pinMode(LED_BLUE, OUTPUT);
pinMode(LED_RED, OUTPUT);
Serial.begin(9600); //set up serial library baud rate to 9600
// Serial1.begin(9600, SERIAL_8N1, /*rx =*/D3, /*tx =*/D2);
}
void loop() {
// put your main code here, to run repeatedly:
Serial.printf("11111222");
log_e("Serial number is invalid, please use a number from 0 to /r/n", );
digitalWrite(LED_BLUE, HIGH);// turn the LED on (HIGH is the voltage level)
delay(200); // wait for a second
digitalWrite(LED_BLUE, LOW); // turn the LED off by making the voltage LOW
delay(200); // wait for a second
digitalWrite(LED_RED, HIGH);// turn the LED on (HIGH is the voltage level)
delay(200); // wait for a second
digitalWrite(LED_RED, LOW); // turn the LED off by making the voltage LOW
delay(200); // wait for a second
}</code></pre>
<p>3.测试情况</p>
<p> </p>
<p>COM33 是 ESP32 C6 开发板串口</p>
<p>COM23 是 CH343 CH343 RX 接16脚</p>
<p>3.1 COM33</p>
<p> </p>
<p>3.2 COM23</p>
<p> </p>
<p> </p>
<p>虚拟串口没有效果，这个板子上的虚拟串口，可以用在打印输出吗 如何使用</p>
<p> </p>
感觉你说的是usb虚拟出来的cdc串口，那个串口可以用，能用来打印/输入，在esp-idf中可以配置，见我的测评贴
