研发部主管今天说了,我们都干得不错,但是公司今年亏损,所以.......
言归正传,谈技术.今天在网上找到一个用MCU做LCD 控制器的文章,可惜只有摘要啊啊啊啊,贴上来大家讨论一下.
Color TFT LCD Controller
Many of the affordable, small, color LCDs on the market are controlled by particular chips that usually aren’t available to the public. The Color TFT LCD Controller is a creative solution that uses two AVR microcontrollers to generate the signals needed to control a color TFT LCD. A 160 × 240 dot Sony ACX705AKM is used as the display. This project is inexpensive and flexible—it may be used as an intelligent LCD controller or a stand-alone device. An ATmega8515 microcontroller, which was chosen for its efficiency, collects the color pixel data from static RAM and controls the LCD by generating digital CRT video signals. An ATmega128 serves as the second microcontroller. It was selected for its abundance of interfaces and large flash memory, which is used to store fonts and bitmaps. The ATmega128 interprets graphic commands received via RS-232 (or any other interface), and stores the resulting pixels in the static RAM shared by the ATmega8515.
