摘要
针对TMS320F2812芯片没有D/A的问题,利用片上设备与外围电路设计用PWM端口实现D/A转换.利用TI公司的IQm ath库,得到了比一般定点处理器运算速度更快、精度更高的正弦值生成方法,并运用该方法对所设计的D/A转换进行了调试,调试结果证明该方法达到了设计要求.
This paper focuses on the problem of no D/A converter on the TMS320F2812 chip, and introduces the method of D/A conversion by utilizing TI＇s library IQmath, the faster processing and ordinary fixed-point processor are obtained. The the on-chip module and peripheral circuit. With higher precision generating value of sine wave than above-mentioned method is used to debug the designed D/A conversion. Debugging results prove that the method meets the design requirements.
