本设计主要是利用单片机做处理器，然后经过数模转换模块进行转换，将单片输

This design mainly uses a single-chip microcomputer as a processor, and then performs conversion through a digital-to-analog conversion module to convert the binary code output by the single chip into the corresponding analog voltage output, so that the designed current source is more accurate. In this module, because of the shift conversion, what I use here is to do the division, and then store the quotient and remainder obtained from the division. Here I use two subroutines, one is to convert decimal to hexadecimal Number system, the second is to use shift and subtract method to do division.

This design is mainly the use of micro-chip as a processor, and then through the digital-mode conversion module to convert the binary code of the single-chip output into the corresponding analog voltage output, so that the design of the current source more accurate. In this module, because of the shift conversion, here I am using to do the divide, and then store the defleation of the resulting business and remainder, which I used two sub-programs, one is to convert the hen system to henrest number, the other is to use the method of shifting subtract to do the divide.
