What I am working on now is a digital display device, which uses a 12864 screen and an operating voltage between 4.5V and 5V. The circuit is very simple, controlled by a single-chip microcomputer and ...
The design is based on 51 single-chip microcomputer and uses 1602 LCD for display. The frequency measurement method uses equal-precision frequency method. The external pulse is used as the start sign...[Details]
The 51 MCU source code is as follows /* A single digital tube displays 0~F in a cycle */ #include reg51.h typedef unsigned char uint8; typedef unsigned int uint16; code uint8 LED_CODE = {0xC0,0xF...[Details]
Problem encountered: An unsigned integer array is defined. The low byte of an element in the array is 0X01FF and the high byte is 0X0200, so an error occurs. Solution: Re-standardize the order of d...[Details]
