TheMPLAB^® Harmony Universal Synchronous/Asynchronous Receiver/Transmitter (USART) driver provides a high-level interface to the USART peripherals. This driver provides application-ready routines to read and write data to the USART using commondata transfer models, thus minimizing application overhead. The USART driver features the following:

• Provides byte-by-byte, Read/Write and Buffer Queue Data Transfer Models.
• Supports interrupt and polled modes of operation.
• Supports point-to-point and addressed type data communication.
• Supports multi-client and multi-instance operation.
• Provides data transfer events.
• Supports blocking (for Real-Time Operating Systems (RTOS) only) and non-blocking operation.
• Features thread-safe functions for use in RTOS applications.
• Supports DMA transfers.

There are two kinds of USART drivers:

Static Drivers

Dynamic Drivers
