这个太难了，stm32封装就那样，引脚间距太小了

                                 

3# IJK 我这边准备接7“彩色数字屏，怎么把CCTV的视频播放到屏上（连续的视频图像）？刷新的频率有多高

建议去下载、看看ST的1篇AN：AN3241，QVGA TFT-LCD direct drive using the STM32F10xx FSMC peripheral

                                 这么酷的处理器，价格也不会便宜，一份钱一份货

引用 9 楼 topplayers 的回复: 找了个sys里用的相似代码，一启动就蓝了，唉

可以先用应用程序尝试调用内核API来创建进程，调试成功后再改成驱动程序，这样可以省些力气。

恩，我试试

不懂  关注一下

打印信息正常的话就说明按键的中断的产生与响应没有问题，应该是你所说的映射字符环节的问题吧。

是智能卡相关的串行通讯吗？

VCC or GND current :(max)+/-75mA 是指整个573工作的最大电流，即相当你对应的驱动电流最大才能75mA. 至于用它驱动8路光藕，得看你的8路光藕 所需要的驱动电流为多大？ 要是一般的额光耦，我得可以用573驱动。 当然还是得看你的光耦的具体参数。

邦顶一下. 有些ARM7的平台上有叫DUMMY 的东西.

我也一样啊，

                                 电子秤里边最基本的“去皮”功能，呵呵 想一想，你每次放上去的托盘重量都一样吗？如果某次放个篓子上去呢？

                                 谁又在挖坟……

具体没用过S1D13775BGA控制器，但好像不影响你的使用。只是将以前的80接口变成RGB接口，这主要取决于你的CPU是否有LCD controller模块，如果CPU中有LCD controller应该同时支持RGB和80接口，只要根据CPU的datasheet设置相关寄存器即可。但如果你的CPU没有LCD Controller接口，你以前是用总线方式点亮LCD的话，那么是用不了RGB接口的屏的。

不管是否有专人，初稿都是要研发作者起草。 有了初稿，那就再说了。

怎么入门？ 首先看你目前所处的环境， 如果你还在学校，建议你多和搞这样的电子爱好者，一起多交流，学习；利用开发板进行 入门的学习。 如果你已经工作，那你最好买块不错的开发板，对照上面的指导，一步步实践 加 修改，加体会 再创新的学习。最好能结合项目，有人带。
