Day 9 Asynchronous Communication
The Plan
Once you remove the clock line from the serial interface between two devices, what you obtain is an asynchronous communication interface. Whether you want full bidirectional (duplex) communication or just half-duplex (one direction at a time), multipoint, or point-to-point communication, there are many asynchronous protocols that can make communication possible and allow for efficient use of the media. In this lesson we will review the PIC32 asynchronous serial communication interface modules, UART1 and UART2, to implement a basic RS232 interface. We will develop a console library that will be handy in future projects for interface and debugging purposes.
