C8051F020單片機通過SPI接口驅動四線電阻式觸摸屏控制器TSC2046，利用中斷方式驅動TSC2046設計軟件。介紹了觸摸屏的工作原理、TSC2046工作方式以及典型應用電路。
Abstract:
The C8051F020 MCU is connected with the TSC2046 which is a 4-wire touch screen controller. The TSC2046 is controlled by interrupt mode, the? operation principle of touch screen is introduced. The operation mode of TSC2046 and typical application circuit are also discussed.
MMC/SD卡以其優越的性能，在單片機嵌入式設備中得到廣泛應用。將MMC/SD卡作為外部掉電存儲介質應用于音頻信號發生器中，通過8051F330單片機上的SPI接口，實現單片機—MMC/SD卡的存儲擴展，設計了此硬件平臺上的MMC/SD卡的單片機驅動程序，并給出了相應的程序代碼，滿足音頻信號發生器的大容量存儲要求。
Abstract:
MMC/SD card is more and more widely used in the single chip embedded devices for their excellent performances.This article introduces the application of MMC/SD card as the external power down storage medium in audio signal generator. The extension technology especially for storage of single chip-MMC/SD card via SPI interfaces in 8051F330 single chip, including designs single chip drive program of MMC/SD card based on hardware platform,and also gives the key coding of the program. The implementation of big capacity storage is meaningful in audio signal generator.
