Algoritma Komunikasi USART dengan Metode Normal Speed dan Double Speed

This paper describes a Universal Synchronous Asynchronous Transmitter and Receiver (USART) serial communication algorithm on the microcontroller with the MATLAB software. The appropriate configuration is necessary for serial communication and it’s obtained the time requirements of the data transmission based on the data load. The methodology of this paper applies the time measurement of the MATLAB function (“tic” and “toc”). It was sent from MATLAB to the microcontroller and returned to MATLAB. The serial transmission mode was used on this measurement by applying the Asynchronous Normal Speed and the Asynchronous Double Speed. The transmission of Double Speed Asynchronous mode having Double Baud Rate configuration than Normal Speed. The value of Baud Rate amount of 2 MBaud and the Asynchronous mode on the normal speeds are 20 data byte and 1000 data byte, it requires of transmission timing around 0,012719 seconds and 0,031394 seconds respectively. Moreover, on the normal speed asynchronous mode of 20 data byte and 1000 data byte, it requires of transmission timing around 0,0117192 seconds and 0,031719 seconds respectively. Therefore, it can get the short statement that the time requirements is proportional compared with the data load.
