中景園OLED帶字庫顯示變量程序求指導(dǎo)

ID:230847 · 發(fā)表于 2019-11-2 16:07

使用的是中景園0.96寸OLED帶字庫屏幕。把示例程序改了一下。想顯示數(shù)字變量，但沒法顯示。下面是我的代碼。請(qǐng)各位師傅指導(dǎo)一下，是不是和指針，指針變量有關(guān)系。謝謝

主程序
#include "all.h"
void OLED_Display_Allot()//想通過X_Num顯示頻率這個(gè)數(shù)字變量
{
uchar X_Num;//顯示一個(gè)變量
uchar *str;
str=&X_Num;
display_GB2312_string(2,20,str);//變量顯示不了，請(qǐng)指導(dǎo)一下
}
void OLED_Display_Init()
{
Rom_CS=1;
lcd_cs1=0;
initial_lcd();
clear_screen();
display_GB2312_string(0,1,"電機(jī)|頻率|狀態(tài)*"); /*在第1頁，第1列，顯示一串16x16點(diǎn)陣漢字或8x16的ASCII字*/
display_GB2312_string(2,1,"X:"); /*顯示一串16x16點(diǎn)陣漢字或8x16的ASCII字.以下雷同*/
display_GB2312_string(4,1,"Y:");
display_GB2312_string(6,1,"Z:");
display_GB2312_string(2,52,"HZ"); /*顯示一串16x16點(diǎn)陣漢字或8x16的ASCII字.以下雷同*/
display_GB2312_string(4,52,"HZ");
display_GB2312_string(6,52,"HZ");
}
void main()
{
P0M0=0;P0M1=0;
P1M0=0;P1M1=0;
P2M0=0;P2M1=0;
P3M0=0;P3M1=0;
P4M0=0;P4M1=0;
P5M0=0;P5M1=0;
Uart1_Init();
OLED_Display_Init();
while(1)
{
OLED_Display_Allot();
}
}
