Fundamentals07 UART Protocol Tutorial or What is serial asynchronous UART communication Protocol
Friends welcome to this video series on Embedded System. In this lecture we are going to understand everything what we need to know to configure UART. We will cover Serial and Parallel communication, Synchronous and Asynchronous communication, Baud rate, UART data frame, Half Duplex and Full Duplex, Advantages and Disadvantages of UART communication.

@nick60444 4 года назад

I don't understand the stop bit. What happens if the binary number you're sending over has a 1 at the end. What distinguishes the stop bit (1) from a 1 at the end of what you're sending over?

@eminberkay Год назад

the receiver has the knowledge of length of data frame. After the data frame bits, for example in this case it is 8, the receiver checks the upcoming stop bit. If the bit is 0, that means don't stop, one more data frame is coming and receiver prepares itself to read upcoming 8 bit dataframe, and then checks again and again... In a thousands of dataframe sequence this saves 1/bps time for each, which makes huge difference.

@LukTzeChing 4 года назад

I have a question: Do both GND pin have to be connected to the same ground?

@TechVedas 4 года назад

Hi, yes, that's the basic principle of UART like wired communication protocol. If Transmitter and Receiver are connected to different reference GND, they will not be able to understand each other's data.

@priyajitghosh2790 5 лет назад

How many slave can be added in same bus (tx,rx line ) in uart?

@TechVedas 5 лет назад

Hi Priyajit, UART specification does not mention Master-Slave arrangement. Please check out the below link which will clear your doubt. www.quora.com/How-can-I-connect-multiple-slaves-to-one-master-using-a-UART-protocol I personally recommend to use I2C instead UART; if your application required more than 2 devices to communicate.

@polumallikarjuna8784 5 лет назад

howmany slaves and masters can be added in same bus for uart and what is maximum speed of uart

@TechVedas 5 лет назад

Hi Mallikarjuna, UART is most suitable for one to one communication where no master slave arrangment required. Even though multiple device can be added but it will increase software load to handle this type of communication. I would rather recommend to use I2C or SPI in this case.

@jancenj2218 4 года назад

pretty much similar to RS-232 protocol?

@ManishKumar-yu8em 5 лет назад

Usart explanation

@TechVedas 5 лет назад

Hi Manish, there is no difference in UART and USART apart from USART can be configured wirh clock. Industry avoid to use Clocked UART as I2C performs better than that. You can check complete i2C tutorial on my chabnel.

How to use the uart interface to combine with the clock? Is there a sample program?

@sharonelza6235 5 лет назад

Does GSM use UART?

@TechVedas 5 лет назад

Hi Sharon, even though I had worked with GSM module communicating over UART but there are GSM modules which supports I2C also. You need to check datasheet of your module.
