The Application of UART Expansion Based on MSP430 Timer

Abstract

By analyzing the principle and technology of MSP430, the characteristics and working mode of UART timer are studied, and the function of UART is realized by using MSP430 timer resource. Experiments show that the performance is stable and the bit error rate is expected to be stable. In the case of not increasing the number of peripheral, the expansion of the number of serial port provides a new way of thinking for serial communication.
