Least Significant Byte of the UART baud rate generator value. The below table shows the registers associated with LPC1768 UART.Ĭontrols the UART frame formatting(Number of Data Bits, Stop bits) LPC1768 has 4-UARTs numbering 0-3, similarly the pins are also named as RXD0-RXD3 and TXD0-TXD3.As the LPC1768 pins are multiplexed for multiple functionalities, first they have to be configured as UART pins.īelow table shows the multiplexed UARTs pins. After this tutorial you should be able to extend it to remaining three UARTS.Īfter understating the basics of LPC1768 UART module, We will discuss how to use the ExploreEmbedded libraries to communicate with any of the UART devices. In this tutorial we are going to discuss the serial communication using UART.įor more info on UART/RS232 check 8051 tutorial.
