SPI is an acronym for (Serial Peripheral Interface) pronounced as “S-P-I” or “Spy”. The baud rate is the rate at which bits are being sent bps (bits per second). There is no incoming serial clock signal, so in order to achieve proper communication between the two ends, both of them must be using the same baud rate. On the other hand, the Asynchronous type of transmitter generates the data clock internally. The Synchronous type of transmitters generates the data clock and sends it to the receiver which works accordingly in a synchronized manner.
USART – Universal Synchronous/Asynchronous Receiver/Transmitter. UART – Universal Asynchronous Receiver/Transmitter. There are actually two forms of UART Hardware as follows: Namely, RX (data input – receiving end) & TX (data output – transmitting end). There is a couple of io pins dedicated to the UART serial communication module highlighted in the following figure. UART is sold/shipped as a standalone integrated circuit (IC) or as an internal module within microcontrollers. Universal Asynchronous Receiver/Transmitter or UART for short represents the hardware circuitry (module) being used for serial communication. Before introducing the I 2C bus, let’s just quickly review the previous serial ports. We’ve also done a handful of practical LABs using both of them. Up till now, we’ve introduced UART, SPI serial communication ports. Digital Storage Oscilloscope (DSO): Siglent SDS1104 (on ).
