单片机与DSP相比,由于其I/0口比较、外设资源丰富等原因多使得其应用范围更广,价钱也相对DSP比较便宜,开发电路相对简单。而 DSP比单片机的处理速度更快,功能更为强大,能够满足需要对数字信号进行处理的环境。<br><br>由于在本系统中,没有比较复杂的数据处理,所以最后从经济合理的角度考虑下我们还是选用了单片微型电脑作为控制器。但同时考虑到在后期的产品设计中可能系统进行了一定程度的扩充更新,对单片微型电脑的系能以及外围资源也有一定的需求,在最后的产品设计中我们采用的是ST公司的STM32F103C8T6型的单片机型芯作为主控芯片。

Compared with DSP, single chip microcomputer has more I / 0 ports and abundant peripheral resources, which makes its application range wider, the price is cheaper than DSP, and the development circuit is relatively simple. DSP has faster processing speed and more powerful function than single chip microcomputer, and can meet the needs of digital signal processing environment.<br>Because there is no complex data processing in this system, we finally choose a single-chip microcomputer as the controller from the perspective of economy and rationality. But at the same time, considering that the system may be expanded and updated to a certain extent in the later product design, and there is also a certain demand for the system energy and peripheral resources of single-chip microcomputer, in the final product design, we use the stm32f103c8t6 single-chip model core of ST company as the main control chip.

Compared with DSP, MCU has a wider application range, cheaper price and simpler circuit development because of its I/O port comparison and abundant peripheral resources.

In this system, there is no complicated data processing, so at last, from the economic and reasonable point of view, we chose a single-chip microcomputer as the controller.
