Coding syntax for the NodeMCU in the IDE follows the Arduino framework, including pin designations and communications ports.īelow is a coding example for the NodeMCU which flashes an onboard LED and also has allows the NodeMCU to generate a text that can be seen through the serial monitor. This completes the configuration of the Arduino IDE to recognize and generate code for the NodeMCU. Arduino IDE NodeMCU Configuration Complete The speed of 115200 is the optimum transfer rate that is used to transfer data to and from the NodeMCU. If Upload Speed is not set to 115200, select the speed of 115200 from the options from that item. These include CPU Frequency, Flash Size, and also Upload Speed. Shown below the Board selection, are several NodeMCU settings. For our example, our NodeMCU added COM6 and will be selected by clicking on COM6. The options list will present the available COM ports. To determine which communications port has been selected on your system, select the Tools…Port menu option. The communication port used will vary by system. Connect your PC by a USB cable to the NodeMCU.Īfter connection, the PC will provide power to the NodeMCU. The communications port must be defined to allow the Arduino IDE to communicate with the NodeMCU. Dayton Hamvention Previous Years Vendors.
