現(xiàn)有基于MAX7219芯片的數(shù)碼管驅(qū)動電路只適用于小尺寸LED，為擴展其使用范圍，在介紹動態(tài)顯示芯片MAX7219功能的基礎(chǔ)上，提出了一個基于該芯片的8位高亮度8英寸數(shù)碼管驅(qū)動電路。電路保留了MAX7219芯片的功能強大、編程簡單等優(yōu)點，通過74LS273鎖存器和ULN2803達林頓驅(qū)動器，實現(xiàn)了對任意大尺寸數(shù)碼管提供較高電壓和電流驅(qū)動的靜態(tài)顯示，并亮度可調(diào)。 Abstract: The existing display-driving circuit based on MAX7219 was only applicable to small-size LED. To expand its use, based on the function introduction of dynamic display chip MAX7219, a display-driving circuit for high-brightness 8-bit LED with the size of 8-inch was proposed. The advantages of MAX7219 were retained, such as powerful function and simple programming. Static display with adjustable brightness for large-size LED with higher voltage and current was achieved with the help of 74LS273 and ULN2803.
