UART Function Summary
This C language subject-sorted list itemizes the constants and driver functions associated with the UART (Universal Asynchronous Receiver Transmitter) Wildcard.
The UART Wildcard implements two full-duplex serial ports that can be configured for RS232, RS422, and RS485 protocols to implement the communications links that are often needed in instrument control applications. This tiny 2" by 2.5" board is a member of the Wildcard™ series that connects to Mosaic's line of microcontroller-based embedded computers. A UART chip (sometimes called a USART) on the Wildcard implements the conversion between the parallel Wildcard bus and the RS232 and RS485 asynchronous serial links. The UART Wildcard makes it easy to add serial communications links to implement instrumentation and automation solutions.
