What we have learnt
- The AHB UART is integral for serial communication in embedded systems.
- Configuration options such as baud rates, data bits, and flow control enhance the adaptability of UART communication.
- Error handling mechanisms play a significant role in maintaining data integrity during UART operations.
Key Concepts
- -- UART
- UART stands for Universal Asynchronous Receiver-Transmitter, a hardware communication protocol for asynchronous serial communication using TX and RX lines.
- -- FIFO Buffer
- FIFO (First In, First Out) buffer is used in UART peripherals to temporarily store incoming or outgoing data, improving communication efficiency.
- -- Baud Rate
- Baud rate refers to the speed of data transmission in bits per second, configurable in UART to match the requirements of connected devices.
- -- Error Handling
- Error handling in UART communication includes detection and management of overrun, framing, and parity errors to ensure reliable data transmission.
- -- Flow Control
- Flow control mechanisms like RTS/CTS are employed in UART to prevent data loss by managing data transmission rates between devices.
