Description: [文件名] Touch.c [功 能] 8051单片机驱动ADS7846/ADS7843芯片 [简 介] ADS7846/7843芯片 适合用在4线制触摸屏，它通过标准SPI协议和CPU通信，操作简单，精度高，当触摸屏被按下时（即有触摸事件发生）则ADS7846向CPU发中断请求，CPU接到请求后，应延时一下再响应其请求，目的是为了消除抖动使得采样更准确。如果一次采样不准确，可以尝试多次采样取最后一次结果为准，目的也是为了消除抖动。-Driver source code of touch-sensitive screen with ADS7846/7843

Description: 基于8051的sd卡驱动程序
适合8051内核单片机的sd卡读写驱动,基于自带SPI模块的单片机AT89S8253修改的.
可以读写单个块或者多个块.
带spi功能的8051单片机应该都不需要修改.
如果要修改只需修改sdconfig.h 和 sdhal.c文件-8051 based on the sd card driver for 8051 MCU core driver sd card reader, based on its own single-chip SPI module AT89S8253 changes. Can read and write single block or multiple blocks. Spi function with the 8051 single- machine should not need to be amended. If you want to modify only files modified sdconfig.h and sdhal.c

Description: AMT630A Emulator and Firmware
AMT630A firmware for mini TFT screens
The AMT640A is a relative common video controller chip found in cheap mini TFT screens with composite input.
Those screens are often sold as "car rear view monitor" (or by similar names), although they are essentially fully-fledged portable TVs (minus tuner/speaker, and without advanced inputs like S-video or RGB).
The chip contains a 8031/8051 microprocessor, with firmware stored on an external SPI-bus FLASH memory chip
