STM32F10X开发包

我在使用陈明计先生写的small RTOS和51单片机做过几个小项目，起初都很好，开发变的容易了，程序变的容易修改。后来随着任务个数的增多，RAM很快就不够用了。51系列的芯片内部RAM普遍都是256个,很难找出1024个字节RAM或更多，而价格又合适的。记得上一次我没有办法被迫使用了64K flash内部带768字节的XRAM的51芯片，而我根本用不到那么多flash。-I use Mr. Chen Mingji written small RTOS and 51 MCU done several small projects at first were very good to develop easy to change the program become easier to modify. Subsequently, the increase in the number of tasks, RAM is not fast enough. 51 series of chip RAM are generally 256, it is difficult to find 1024 bytes of RAM or more, while prices will be appropriate. I remember the last time I had no way forced to use a 64K flash with 768 bytes of internal XRAM of 51 chips, and I will never use that much flash.

ST7920驱动器的可实现程序，使用51/52单片机接口正确即可显示-ST7920 drive can be realized, the use of 51/52 single-chip interface to display correctly

基于 avr ATMEGA 128 利用用查表方式 输出SPWM 波，经滤波后 可观察到 50HZ 正弦信号，可 用于H桥逆变，带有死区时间。

atmel at91系列的TC操作手册（产生中断），相信对需要的人有帮助，主要涉及到计算产生频率和比较触发寄存器加载值的计算。-atmel at91 series manual TC (generate an interrupt), believe that those who need help, mainly related to the calculation and comparison of the frequency generated trigger to calculate the load register.
