用cubemx配置好之后，注意LCD configuration的voltage sourceselection要选择外部供电，externa。否则初始化会卡死的

void MX_LCD_Init(void)
{

  hlcd.Instance = LCD;
  hlcd.Init.Prescaler = LCD_PRESCALER_1;
  hlcd.Init.Divider = LCD_DIVIDER_16;
  hlcd.Init.Duty = LCD_DUTY_1_4;
  hlcd.Init.Bias = LCD_BIAS_1_3;
  hlcd.Init.VoltageSource = LCD_VOLTAGESOURCE_EXTERNAL;
  hlcd.Init.Contrast = LCD_CONTRASTLEVEL_0;
  hlcd.Init.DeadTime = LCD_DEADTIME_0;
  hlcd.Init.PulseOnDuration = LCD_PULSEONDURATION_1;
  hlcd.Init.HighDrive = LCD_HIGHDRIVE_0;
  hlcd.Init.BlinkMode = LCD_BLINKMODE_OFF;
  hlcd.Init.BlinkFrequency = LCD_BLINKFREQUENCY_DIV8;
  hlcd.Init.MuxSegment = LCD_MUXSEGMENT_DISABLE;
  if (HAL_LCD_Init(&hlcd) != HAL_OK)
  {
_Error_Handler(__FILE__, __LINE__);
  }

}
