https://www.raspberrypi.org/blog/raspberry-pi-2006-edition/  筆者發文說他曾經做過的電路板 25元 美金 These boards use an Atmel ATmega644 microcontroller clocked at 22.1MHz,  and a 512K SRAM for data and framebuffer storage. 32點io 點輸出 19 of the Atmel’s 32 GPIO lines are used to drive the SRAM address bus. 有一個螢幕輸出 To generate a 320×240 component video signal, 有序列輸出的模擬類比輸出  the Atmel rapidly increments the address, and the data lines are fed via 74HC-series buffers to a trio of simple summing-point DACs; during horizontal and vertical blanking, 他是免費分享的  it is free to perform other operations. Here’s a video of the device in action. 只是簡單的影片 Not quite Quake 3, I’m sure you’ll agree, but maybe familiar to fans of 也須你可以看看這個  David’s 1987 classic Zarch. In the end, I felt that much higher performance, 有電路文件與pcb分享  and the ability to run a general-purpose operating system, outweighed the benefits of home assembly, but it’s still a neat design. T...
