keil编译出错
SNAKE.C(205):errorC249:\'DATA\':SEGMENTTOOLARGEkeil编译时出现上面的错误，为什么会出现这种错误？怎样改正？大家帮小弟看一下keil编译出错你用的是KEILC51的吧，KEILC51的DATA区能定义的变量大小比较小，128还是256吧。上面的问题就是，DATA区不够用了。建议你把数组长度比较大的变量加上xdata放到外部数据区去，如charxdatabuf，坏处就是速度会慢。尽量节约软件资源：ROM一般的来说问题不...

CCS3.3烧写F2812
大家好，我刚刚开始学习DSP，完成了F2812的硬件仿真，现在想尝试用CCS3.3给F2812烧写固化程序，遇到问题：1.CCSv3.3的TOOLS菜单下没有onchipflash28x的选项，请问这个是需要安装补丁软件吗？如果需要，应该安装那个补丁？2.仿真时使用的仿真器是老师的，据说是外国货，比较贵，这个烧写F2812跟仿真器有关系吗？3.烧写时需要对CCS3.3进行设置吗？希望大家能给予帮助，非常感谢CCS3.3烧写F2812CCS安装完成后，只需要安装USB驱动，没...

电子产品的安全距离及其相关安全要求
所谓安全距离，就是为保护人在使用电子产品的时候，危险电压带电部分与人不能轻易接触到，也不能让它来引起危险导致威胁人身安全。因此必须在一般情况下，安全距离是在产品设计中最重要的部分之一。检查安全距离从设计阶段开始。结构检查人员会首先检查PCB板上的安全距离（最好拿空的PCB板用透明薄尺或游标卡尺来测量），之后，就是检查危险电压带电部分与其它部分（如外壳、安全电压部分等）距离等等。总之，一切关乎与安全的部分都要测量，特别重点会在电源部分。具体参考各种安全标准：IEC60950\\IE...
