介绍几种cpuThe 8xC251SA/SB/SP/SQ improves on the MCS
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 adva

Stm32_ucos_4
该程序使用消息邮箱，在内存空间开辟了一片区域，供4个任务共享读写。1个任务在写内存时，其它任务不能读写。多个任务可以同时读该内存区域数据。(This program uses the message mailboxes, the memory space to open up a regional, shared reading and writing for the four tasks. A task to write the memory and other tasks can not read and write. More than one task can read the memory area data.)

移植到MCS51的uCOS_II。
1。在文件OS_CORE.C中OSMapTbl和OSUnMapTbl数组用于查表，所以应该放在code里。
增加code关键字。UCOS_II.H和OS_CORE.C。
2。OS_CFG.H堆栈大小MaxStkSize改为900。
3。OS_CPU_C.C的InitTimer0函数增加了关于开T0中断的解释。
允许T0中断，此时EA=0(51上电缺省值)，中断还不会发生，满足在OSStart()前不产生中断的要求。
4。修改中断处理流程，以便严密监视中断嵌套情况。每个中断进入后立即进行OSIntNesting+1原语操作。
5。增加printf函数的移植，支持灵活的数据显示。支持标准或长二进制/八进制/十进制/十六进制/无符号整数，
支持字符、字符串、浮点数、百分号％。其中，浮点数在整个范围内被完全支持，统一采用科学记数法显示。
