AI8051数据类型

天*** · 发表于昨天 20:41

刚刚焊了一块Ai8051U最小系统板,
昨天买的5片芯片今天上午到货,
测试了一下USB下载功能.
先按下P3.2,再插上USB数据线,
串口就识别出来了.
春节买的5块芯片可以识别,
固件没有USB下载功能,
系统提示可以用USB LINK1D 下载

  晚上想测试一下IIC 0.96OLED
把原来的uchar 类型改成了 u8
编译Write_IIC_Command(0XB4+y);       //纵向页这句话是产生以下警告

         main.c(174): warning C188: 'parameter 1': value truncated

函数原型是这样的 ,变量IIC_Command已经定义为U8了

         /*************IIC Write Command*****************/
            void Write_IIC_Command(u8 IIC_Command)
            {
            IIC_Start();
            Write_IIC_Byte(0x78);             //Slave address,SA0=0
            Write_IIC_Byte(0x00);             //write command
            Write_IIC_Byte(IIC_Command);
            IIC_Stop();
            }

整个程序如下
#include "../../comm/AI8051U.h"
#include "stdio.h"
#include "intrins.h"
#define    high 1
            #define    low 0

关于AI8051数据类型及编译警告问题的说明如下：

在使用AI8051系列芯片进行开发时，正确理解和使用数据类型是保证程序稳定运行的基础。当前用户在测试过程中遇到的“parameter 1: value truncated”警告，主要源于对u8类型与常量值之间的匹配问题。

首先，AI8051平台支持的标准数据类型包括：u8（无符号8位整型）、s8（有符号8位整型）、u16（无符号16位整型）、s16（有符号16位整型）等，这些类型在编译器中均被严格定义为对应长度的数值范围。其中，u8的取值范围为0~255（即0x00~0xFF），超出该范围的数值将导致截断（truncated）现象。

在用户提供的代码片段中，WriteIICCommand(0XB4+y);这一语句存在潜在风险。虽然y可能是一个u8类型的变量，但0xB4本身是一个十六进制常量，其十进制值为180，属于u8的有效范围。然而，如果y的值超过75（即0xB4 + y > 0xFF），则会导致参数溢出，从而触发编译器警告。

建议用户检查y的取值范围，并确保其与0xB4相加后的结果不超过255。例如，可添加边界判断逻辑或调整计算方式，以避免数据截断。

此外，关于USB下载功能，AI8051U系列芯片支持通过USB LINK1D工具实现固件更新。若使用的是早期版本的AI8051芯片（如春节购买的5片），由于固件未集成USB下载功能，需依赖外部烧录工具完成程序加载。建议用户确认所用芯片的型号和固件版本，以确保兼容性。

综上所述，AI8051的数据类型管理及编译警告处理是开发过程中不可忽视的环节。合理使用数据类型、严格控制数值范围，能够有效提升程序的稳定性和可靠性。如有进一步技术问题，欢迎联系国芯人工智能技术支持团队。

      用了一个障眼法
      先定义一个变量Z
并且赋初值0XB4;
执行完语句Write_IIC_Command
再加Y地址
            z=0XB4;
            for(y=0;y<2;y++)                //百位显示
            {
            Write_IIC_Command(z);       //纵向页 1011
            z=y+0XB4;

但是OLED 还没有显示
今天奔波了一天
明天继续

早晨继续测试
添加了OLED初始化函数
修改了延时值

出现了雪花
隐隐约约的数字隐藏在雪花里
