The serial device sends the command "AT+ENTM" to the module. After receiving the command, the module will echo "+OK" and return to the previous working mode. 3 ESP32 does not have an RS485 interface, and an external module is required to add an RS485 interface. The hardware connection...
digitalWrite (6, HIGH) and (LOW) does not have any effect. I even did put in pinMode(6, OUTPUT) In boardmager I have selected LOLIN(WEMOS) D1 R2, and also checked ESP 8266 generic. I expect its something simple what I have missed?
I2C Slave is currently not working in ESP32-P4. Ongoing investigation. RainMaker sketches are crashing in the current version. Pending fixes from RainMaker team. What's Changed System PR IDF release/v5.3 by @me-no-dev in #10258 DF release/v5.3 by @me-no-dev in #10272 IDF release/v5....
blinkState; digitalWrite(LED_PIN, blinkState); } 编译并上传,打开串口监视器,修改串口监视器的串口速率与代码里的相同,我这里是 Serial.begin(38400); 我们可以看到串口监视器里有数据输出。并且板载蓝色的led灯也在闪烁。串口输出的数据可以从上面的代码中看出。
