Serial Peripheral Interface (SPI) - SparkFun Learn

WebIntroduction. Serial Peripheral Interface (SPI) is an interface bus commonly used to send data between microcontrollers and small peripherals such as shift registers, sensors, and SD cards. It uses separate clock and data lines, along with a select line to choose the device you wish to talk to. WebMay 11, 2024 · FTDI FT232RL serial-usb chips can run at 2Mbd , i.e. 200kbytes/sec. This is much faster than the I2C rate. Say you read I2C at max rate of 400kHz (44kByte/s), you only need 887kBd to send the data back as hex-ascii (2 chars/byte). Of course that is the sustained I2C read rate once addressed.
