TMS302F2812 的 EVM 很好的硬件设计参考资料-TMS302F2812 the EVM good hardware reference design

x5045有四种功能：分别是上电复位、看门狗定时器、电源电压监控和块锁保护串行eeprom的功能， 该程序通过改变控制寄存器的参数可以实现看门狗定时器监视电压和设置保护rom区，每次复位后 地址计数器都是该区的首地址（个人观点），即断点地址。 问题：其实对该芯片的应用还是很模糊-x5045 four functions : the reduction of electricity, watchdog timer, Supply voltage control and protection block serial eeprom lock function, The procedure by changing the parameters of control register can be achieved watchdog timer and set up surveillance voltage protection rom, After each reset address counter area is the first address (personal view), breakpoint address. Question : In fact, the application of this chip is still very fuzzy! !

ZLG7289键盘显示接口芯片是一个很常用的接口芯片，至需4个IO口接可以控制显示8位的数码管显示和64个矩阵键盘的自动扫描，效果很好。-ZLG7289 keyboard display interface chip is a very common interface chip, to take four IO access can be controlled mouth shows 8 digital tube display and keyboard matrix 64 automatically scans, very good.

数码管显示，希望和 大家交流，将这个程序进行该进。-Digital tube display, hopes and U.S. exchanges, will this process of the Progressive.

msp430ex44x试验程序代码包括 io口，spi通信，定时器，实时时钟等代码，非常全-msp430ex44x test program code, including io port, spi communication, timer, real-time clock and other code, is very full

x25045的编程应用，它具有512字节的EPROM，看门狗，复位信号等，是MCU不错的外围芯片-x25045 programming application, which has 512 bytes of EPROM, watchdog, reset signal, MCU is a good peripheral chips

我下载了原有的文档，发现其中关于串口部分的波形缺失。我这份比较全。-I downloaded the original document, found on the serial port part of the waveform missing. I compared the whole.
