[讨论] Almond路由器是如何驱动LCD的?

[复制链接]
发表于 2013-9-6 15:40:38 | 显示全部楼层 |阅读模式
Almond路由器带了个LCD,芯片是RT3052F的芯片。但是此芯片没有LCD接口。
哪位大神研究过RT3052F是怎么驱动屏的吗 ?
看屏的走线也很多,不可能是SPI接口的屏,有点像8080接口的,怎么驱动的呢?
谁知道告知一下,很好奇,谢谢。

LCD接口:

并口 ( Parallel LCD Interfacing)
串口 (serial RS-232)
FPGA

LCD interfacing:

LCD are connected to microcontroller through a LCD interface IC or directly to it's address and databus and few control pins, Few of the today's latest microcontrollers have built-in LCD driver.
Also some of the LCDs support serial interface.
Here are few nice articles on LCD interface from the internet and our own module, you can choose based on your interest from the below list of LCD interface articles.
