Setting up additional SPI ports. I would like to have Arduino send short commands to PSoC 042 BLE (like "start" , "sleep" etc) via SPI communication. SPI is intended for communicating over short distances at relatively high speeds. Just to elaborate more on the pros and cons, even if you have a ready made library to communicate over i2c, spi, BLE, uart, etc., It's important to know that there are sections of code where talking to the outside world might be a very bad idea. Connections Explained. Facebook Twitter LinkedIn Google + Email. So can anyone please tell me what the connection should be like for UART using RC522, and also give me a sample code and library links to achieve the same. SPI interface and serial device data interchange 3. This article will compare the various interfaces: UART, SPI and I2C and their differences. All devices have transmitters and receivers.
