(Inserting this script in the package.json: "install": "electron-rebuild" ). The electron-rebuild require a python installed in the computer, so I have installed through windows-build-tools. (installed globally) So now when I run the

Sending bytes to serial port using Node.js

由 心已入冬 提交于 2019-12-08 09:11:58
问题 I am planning to do a POC with serialport communication using Node.js. I googled and found the "serialport" module for Node.js. I have a C# code which writes the data to the serial port in byte datatype. I would like to try the same using Node.js. The C# code has the following values in the byte[] array: 5, 170, 85, 250, 0, 86, 0, 3, 158, 0 Could anyone please tell me how to achieve this using Node.js's serialport module? 回答1: Finally I was able to figure it out. Just create a buffer variable
