开源mega8玩转SPI接口TFT彩屏

luckroll · 发表于 2009-4-9 22:46:49

做了个spi接口的TFT彩屏的转接板在上面顺便放了个MEGA8以及USB接口 mega8的引脚几乎都引出来了
自己觉得SPI接口的彩屏很有玩头准备全部开源欢迎拍砖以便于提高一下自己的软硬件水平

请问楼主用SPI刷新一屏大概要用长时间？

luckroll · 发表于 2009-4-10 10:40:28

如果用AVR 硬件spi最高速度是Fosc/2 屏设置为65K色方式刷新一屏需要130X130X16=270400个SCK
用AVR模拟IO的话时间会慢很多

zy_sh_npk · 发表于 2009-4-10 10:57:12

不错呀，不知道能接在STM32 的开发板上面吗？再移植个UCGUI就更好了。
130X130X16=270400个SPI的SCK，按这个计算，是用内部SPI模块，刷新频率不错呀。
不过不知道这个屏支持的最快SPI频率是多少？STM32的SPI驱动频率可能跑到18M呀！

luckroll · 发表于 2009-4-10 11:16:10

【12楼】 zy_sh_npk
屏的Clock Cycle Time Typ值是50ns 也就是可以支持20M 最高SPI驱动频率还可以更高

谢谢LUCKROLL，我后来看了PDF介绍那块液晶的，确实是这么连。但是现在还是驱动不了，不知道哪个地方出问题了。

看下图的右边，我那块板子只有下半部分才和你发的板子相同。板子原来焊好了5V转3.3V的模块，焊了几个电阻，如图。

但是我看那电路还不通，如转接板的1脚通过R15之后就没有了，我用焊锡连到R16的同一头（用黄色箭头表示），R16那头有个小孔到转接板正面，连到LCD的11脚，和原理一样了。另外改的地方还有R1,R2,R3的地方原来没有和3.3V的相连，我用焊锡把这三个电阻并联了连到R4那去，R4那地方本来是直接用焊锡连通的。

改了之后还是没有，用的是和液晶一起发过来的程序。难道是我改错了吗，还是别的问题，麻烦大哥你指点下了，再次谢过！

1. 43楼的图是做USBASP或者AVR-CDC CDC-IO用的上面焊了mega8芯片可以做USBASP或者CDC-IO USB转232等等

2. 51驱动屏的话有些51芯片的驱动能力不够 P2口要加上拉电阻

我用的是 STC的51，除了P0口好像都片内加上啦电阻了啊，43楼的图和我收到的转接板很相似，电路连接不知道还有没有问题，我再检查一下P2口输出的电平看看

joyko · 发表于 2009-7-7 18:28:33

p2口输出为高时是4.7~4.8V的电压，看这个屏的资料说IO口输入电压最大值是4V，不知道有没有烧坏了。
经过多次折腾，背光灯的排线已经接触不行了，该屏只能废弃了。

5v系统的话屏按这个图焊接

M128 如何连接该SPI屏？程序能用M16的吗？

这个一定要顶，屏和M16都有了，嘿嘿，试试硬件SPI
