项目开发中遇到的问题： 1、上电瞬间点阵屏显示乱码问题： 猜测：由于BK3431Q芯片加电时所有I/O为高电平,加电时可能595上电比BK3431Q快,所以上电被认为是一个正脉冲跳变,结果595内部的寄存器初始值被输出，网上看论坛别人给出的解决方案如下：
1.试试RCK反相后再进595,这样BK3431Q上电时的脉冲反相后成为负的,使595不输出.
2.OE用单片机I/O控制,由于上电时BK3431Q为高电平,所以无输出,然后程序控制595输出.
3.加大C26的值,让595的OE输出比51复位慢. 加粗的是本人采用的解决办法 硬件电路图： 点阵屏是在网上购置的现成的32*32的点阵改的24*24，行低电平灯亮，列高电平灯亮（由于列用到了MOS管反向，实际控制中单片机的相应位送低电平） 由于硬件上的限制，此点阵屏只能列扫描，mos管才能发挥作用，如若用行扫描，led灯显示亮度会很弱   字模取模方式如下图所示： 74hc595Led.c源代码： #include "gpio.h" #include "74hc595Led.h" #include "BK3435_reg.h" #include "uart.h" #include "app_task.h" #define HC595_SH_CLK 0X13 //74HC595的时钟 #define HC595_DS_DATA 0X33 //74HC595的数据 #define HC595_ST_LATCH 0x12 //74HC595的锁存 #define SCL_HIGH() gpio_set(HC595_SH_CLK,1) #define SCL_LOW() gpio_set(HC595_SH_CLK,0) #define SDA_HIGH() gpio_set(HC595_DS_DATA,1) #define SDA_LOW() gpio_set(HC595_DS_DATA,0) #define LATCH_HIGH() gpio_set(HC595_ST_LATCH,1) #define LATCH_LOW() gpio_set(HC595_ST_LATCH,0) #define SDA_SetInput() gpio_config(HC595_DS_DATA,INPUT,PULL_NONE) #define SDA_SetOutput() gpio_config(HC595_DS_DATA,OUTPUT,PULL_NONE) #define SDA_READ() gpio_get_input(HC595_DS_DATA) bool StartDelayFlag = 0;
