CCS中用c55x实现AD转换
模数转换相对于计算机来说是一个较为缓慢的过程。一般采用中断方式启动转换或保存
结果,这样在CPU 忙于其他工作时可以少占用处理时间。设计转换程序应首先考虑处理过
程如何与模数转换的时间相匹配,根据实际需要选择适当的触发转换的手段,也要能及时地
保存结果。
由于TMS320VC5509A DSP 芯片内的A/D 转换精度是10 位的,转换结果的低10 位为
所需数值,所以在保留时应注意将结果的高6 位去除,取出低10 位有效数字。-CCS AD conversion using c55x ADC to achieve relative to the computer is a relatively slow process. An interrupt normal start conversion or save the results, so the CPU can be busy with other work less processing time. Design conversion process should first consider how the ADC matches the time, according to the actual need to select the appropriate means to trigger change, we must be able to save the results in time. As TMS320VC5509A DSP chip for A/D conversion precision is 10-bit conversion result of the lower 10 to the desired value, so reservations should pay attention to the results in the high six removed, remove the lower 10 digits.
