使用互斥信号量解决ucosii中的优先级反转-The use of mutex semaphores to solve the ucosii Priority Inversion

应用背景Logical separation of program and data memory All 8051 devices have specific memory organization, they have separate address spaces for Program (ROM) and Data (RAM) Memory. This logical separation of Memory is useful because it allows the Data Memory to be accessed by 8-bit addresses, which can obviously be more quickly stored and manipulated by an 8-bit CPU. Of course, the l6-bit Data Memory addresses can still be generated with the DPTR register. Program Memory Program Memory can only be read, not written to. The address space for 8051 core is 16- bit, so there is maximum of 64K bytes of Program Memory. Up to 4 Kbytes of Program Memory can be on chip, internal Program Memory of the 8051 core. For access to external Program Memory is used signal PSEN (Program Store Enable). Data Memory Data Memory is on a separate address space than Program Memory. For external Data Memo

是modbus的C写的源代码,可移植到任意的芯片.该代码用在freescale 芯片.用的是大端模式.如果到小端模式的芯片需要稍微修改一下.-Is the modbus source code written in C, portable to any chips. The code used in the freescale chips. Using a big endian mode. If the little-endian mode of the chip need to be slightly reformulated.

FAT16文件系统源码,很详细,值得参考!-FAT16 file system source code, very detailed, it is also useful!

一个用于ARM的基4/基5定点FFT算法，原作者是JDB，后来我扩展过16和256点的计算并用在项目中了，感觉速度还不错。现在重写了基于Linux GCC4的测试程序，可供使用者评估参考。建议安装FFTW3用来精确评估测试结果，相关范例已经在代码中了。-Radix 4/5 FFT routines supporting 16/64/256 and 20/80 calculations. The source originally contributed by JDB, I had extended 16 and 256 candidates and used it in our project it has been verified as fast and stable. Now we add some test vectors running on Linux with GCC 4 for testers who want to use or just evaluate it. Installing FFTW3 is recommended for evaluating the code exactly.
