Description: 介绍几种cpuThe 8xC251SA/SB/SP/SQ improves on the MCS-51 architecture and peripheral features, introducing the advanced register based CPU architecture i.e., the MCS 251 microcontroller architecture. The register based CPU supports a 40-byte register file. In addition, the 8xC251SA/SB/SP/SQ microcontroller has 256-Kbyte expanded external code/data memory space and 64-Kbyte stack space. The new controller is also specially designed to execute C code efficiently. More importantly, the 8xC251SA/SB/SP/SQ maintains binary code compatibility with MCS 51 microcontrollers but at the same time allows the use of the powerful MCS 251 microcontroller instruction set, with many new 8, 16 and 32 bit instructions available. The 8xC251SA/SB/SP/SQ has 512 bytes or 1 Kbyte of on-chip data RAM options and is available in 16 Kbytes and 8 Kbytes of on-chip ROM/OTPROM or ROMless options. -introduced several cpuThe 8xC251SA/SB/SP/SQ improves on the MCS-51 architecture and peripheral features, introducing the advanced register based CPU architecture ie, the MCS 251 microcontroller architecture.

Description: 多任务 多进程 51 单片机 C 语言
1.本程序不使用任何汇编指令
2.由定时器T0产生中断，切换进程
3.由于中断或调用子程序，要把PC堆栈，故可以以SP为基址的地方找到PC
4.中断或子程序返回，要把SP出栈给PC，故可以操作SP改变程序入口
5.本程序经调试运行 电路图已上传
6.程序编译是会有一个警告提示，为正常现象，因为保存R0-R7时，重新定义地址，
出现地址覆盖的警告提示。
7.用户以此模板写程序只需写用户的进程子程序和用户初始化子程序，并把各进程参数
放在规定地方，各程序放在规定地方就可以；所有的任务调度已处理好。

Description: 本人做的稳压可调，显示电流，电压电源。
ADC0832，51，可调稳压电源，数码管显示电流（MA）电压（单位V），稳压管最小导通电压2MA，经过改装达不到，这样的改装，避免变阻器接触不良，造成高电压，运放放大1R电压的电流，有点小误差的，c文件ADC0832时序程序，经过调试相当接近标准。
那个运放做成实物的时候可能替换为单电源的，Proteus运行不了单电源的。
版本 Proteus Pro 7.7 SP-I do adjustable regulator, showing current and voltage power supply.
ADC0832, 51, adjustable power supply, digital display current (MA) voltage (V), the minimum turn-on voltage regulator 2MA, modified reach, such modification, to avoid bad rheostat, resulting in high voltage , 1R amplified voltage op amp current, a little error, c file ADC0832 timing procedures, after debugging is very close to standard.
That when the op amp may be replaced in kind made of a single power supply, Proteus can not run a single power supply.
Version of the Proteus Pro 7.7 SP
