Basics of the SPI Communication Protocol
https://www.electronics-lab.com/basics-spi-communication-protocol/
circuitbasics.com talks about the SPI serial communications protocol: One unique benefit of SPI is the fact that data can be transferred without interruption. Any number of bits can be sent or received in a continuous stream. With I2C and UART, data is sent in packets, limited to a specific number of bits. Start and stop conditions define the beginning […]
Chrome Apps and serial port communication
https://www.electronics-lab.com/chrome-apps-serial-port-communication/
Luca Dentella writes: During the development of my electronic projects, I sometimes need to develop a graphical user interface (GUI) that talks using serial communication with the devices I create. In the past, I usually chose to develop those interfaces in C# and using the .Net Framework; framework which allows a rapid development, offers great ways to customize the […]
