说明:  实现一个简易函数信号发生器的功能。系统上电后,默认输出低电平(无波形),默认初始频率为1KHz。波形输出频率可由开发板上的拨码开关SW0~SW3调节,可调范围为1KHz到2KHz,步进量为100Hz。波形由开发板上的DAC_A口输出。共有方波和三角波,正弦波三种波形可供选择,用户只需将开发板上的拨码开关SW6~SW7置成不同取值组合,就可以输出不同波形。其中方波的占空比可以用开发板上的按键开关BTN0~BTN1调节。系统重置按键为开发板上的按键开关BT7。
(To achieve a simple function of the signal generator. System power-up, the default output low (no waveform), the default initial frequency of 1 kHz. Waveform output frequency by the development board DIP switch SW0 ~ SW3 adjustment, adjustable range 1KHz to 2KHz, stepping amount 100Hz. Waveform output by the development board DAC_A mouth. Total square wave and triangular wave, sine wave three waveforms to choose from, users simply the development of on-board DIP switch SW6- SW7 set to different values ​ ​ of a combination of different waveforms can be output. The duty cycle of the square wave with the key switch on the development board BTN0 ~ BTN1 regulation. System reset button for the development of the key switch on the BT7. In addition, after the acceptance of the experiment, I continue to add sawtooth output.)

This folder contains data for incremental compilation. The compiled_partitions sub-folder contains previous compilation results for each partition. As long as this folder is preserved, incremental compilation results from earlier compiles can be re-used. To perform a clean compilation from source files for all partitions, both the db and incremental_db folder should be removed. The imported_partitions sub-folder contains the last imported QXP for each imported partition. As long as this folder is preserved, imported partitions will be automatically re-imported when the db or incremental_db/compiled_partitions folders are removed.
