很有用的单片机资料

ZLG7290B 是广州周立功单片机发展有限公司自行设计的数码管显示驱动及键盘扫描 管理芯片。能够直接驱动8 位共阴式数码管（或64 只独立的LED），同时还可以扫描管理 多达64 只按键。其中有8 只按键还可以作为功能键使用，就像电脑键盘上的Ctrl、Shift、 Alt 键一样。另外ZLG7290B 内部还设置有连击计数器，能够使某键按下后不松手而连续有 效。采用I2C 总线方式，与微控制器的接口仅需两根信号线。该芯片为工业级芯片，抗干扰 能力强，在工业测控中已有大量应用。-Canton weeks ZLG7290B is Ligong Singlechip Development Co., Ltd. to design the digital tube display driver and the keyboard scan management chip. Can directly drive a total of 8 vaginal digital tube (or 64 independent LED), at the same time management can also scan up to 64 keys. Which has 8 buttons can also be used as function keys, like the computer keyboard on the Ctrl, Shift, Alt keys like. Another internal ZLG7290B batter has also set up counters, can press a button and a row after不松手effective. Using I2C bus mode microcontroller interface with only two signal lines. The chip-on-chip for industry, anti-interference ability, in the industrial measurement and control has been a large number of applications.

增加ASCII.C的一个ASCI码(7F),用于虚拟按键用 修改UART串口的命令解析程序，修改RTC的pcf8563中断部分。 精简IIC和smart_timer代码,添加define.h的宏定义。 修改system.c里的消息堆栈的宏定义 增加ii.c函数,支持对eeprom的打包 增加由PLD或者GPIO输出的模拟UART，在6个CLOCK下速度为57.6K 增加消息的优先级功能，消息类型的前4位为消息的优先级，后4位为消息的类型 试用于初学单片机并且想更上一层楼的，或者有些基础，想减少工作量的。-an increase ASCII.C the ASCI code (7F) for the virtual keys with serial UART to amend the order analytic procedures, the revised RTC pcf8563 interruption part. IIC and smart_timer streamline code, add the definition of Acer define.h. The revised system.c news stack macros increase II.c function, support for EEPROM packaged increase from the PLD or GPIO output analog UART, in the next six CLOCK speed of 57.6K news of the priority function of the type of information before news of the four priority levels after four types of information on the trial beginner to a higher level and SCM, or some foundation, we want to reduce the workload.
