pI7d1y9

16*16 dot matrix

Overview

The main control uses STC15F2K60S2 with a built-in crystal oscillator (which saves a little more). Two 74HC138D cascades are used for row selection, and two 74HC595 cascades are used for column selection. In this project, the EN enable terminal of 74HC595 was not connected to the microcontroller pin (as a result, the nearby lights may be dimly lit on the display. Fortunately, it passed The program has been improved), I suggest everyone pay attention to it when designing. Because the output capability of the 74HC595 is limited (the display will be darker without a triode), so a triode is added to enhance the output capability. It comes with three independent buttons, which can switch the display mode or add more new functions.
