Waveform generation is required in various types of sensing, actuation, and time domain reflectometry (TDR) applications. The output frequency and phase are software programmable, allowing easy tuning. No external components are needed. The frequency registers are 28 bits wide: with a 25 MHz clock rate, resolution of 0.1 Hz can be achieved; with a 1 MHz clock rate, the AD9833 can be tuned to 0.004 Hz resolution. The AD9833 is written to via a 3-wire serial interface. This serial interface operates at clock rates up to 40 MHz and is compatible with DSP and microcontroller standards. The device operates with a power supply from 2.3 V to 5.5 V. The AD9833 has a power-down function (SLEEP). This function allows sections of the device that are not being used to be powered down, thus minimizing the current consumption of the part. For example, the DAC can be powered down when a clock output is being generated.\n\nLibDriver AD9833 is a full-featured driver of AD9833 launched by LibDriver.It provides the function of direct digital frequency synthesis(DDS) output 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 AD9833 source files.\n\n/interface includes LibDriver AD9833 SPI platform independent template.\n\n/test includes LibDriver AD9833 driver test code and this code can test the chip necessary function simply.\n\n/example includes LibDriver AD9833 sample code.\n\n/doc includes LibDriver AD9833 offline document.\n\n/datasheet includes AD9833 datasheet.\n\n/project includes the common Linux and MCU development board sample code.
