It integrates TCP/IP protocol stack, which can realize bidirectional transparent transmission between network data packets and serial data. It has 4 working modes: TCP CLIENT, TCP SERVER, UDP CLIENT and UDP SERVER. The serial baud rate can be up to 921600bps. It can be easily configured by upper computer software or serial commands, which is convenient and quick.\n\nLibDriver CH9121 is the full function driver of CH9121 launched by LibDriver.It provides tcp server, tcp client, udp server, udp client and other functions. LibDriver is MISRA compliant.\n\n### Table of Contents\n\n  - [Instruction](#Instruction)\n  - [Install](#Install)\n  - [Usage](#Usage)\n    - [example basic](#example-basic)\n  - [Document](#Document)\n  - [Contributing](#Contributing)\n  - [License](#License)\n  - [Contact Us](#Contact-Us)\n\n### Instruction\n\n/src includes LibDriver CH9121 source files.\n\n/interface includes LibDriver CH9121 UART platform independent template.\n\n/test includes LibDriver CH9121 driver test code and this code can test the chip necessary function simply.\n\n/example includes LibDriver CH9121 sample code.\n\n/doc includes LibDriver CH9121 offline document.\n\n/datasheet includes CH9121 datasheet.\n\n/project includes the common Linux and MCU development board sample code.
