关于stm32的使用HAL库编写
在关于OLED 屏
/* USER CODE BEGIN 2 */
OLED_Init();
OLED_Clear();
在Whlie中加入
sprintf((char *)A," Data ");
OLED_ShowStr(50,0,(unsigned char *)A,2);
sprintf((char *)B," CNBR : %d ",CNBR);
OLED_ShowStr(20,2,(unsigned char *)B ,2);
sprintf((char *)C," VNBR : %d ",VNBR);
OLED_ShowStr(20,4,(unsigned char *)C,2);
sprintf((char *)D," IDLE : %d ",IDLE);
OLED_ShowStr(20,6,(unsigned char *)D,2);
可以显示
但是加按键判断OLED不显示
while (1)
{ static uint8_t value;
if(HAL_GPIO_ReadPin(GPIOB,GPIO_PIN_0)==GPIO_PIN_RESET)
{
value = 1;
}

}

{
value = 3;
}

}
else value=0;
return value;

可以指正下吗/万分谢谢！
