6068L R61509VN 使用hal库lcd没有反应

67466235

用标准库没有任何问题 hal库我参照了https://blog.csdn.net/qq_41811106/article/details/103363672
fsmc的时序和标准库中设置的是一致的，但是lcd没有初始化，黑屏。

标准库程序是开发板资料里面的 ： FSMC-TFTLCD显示实验 这个可以显示
但是我移植到hal库后 lcd就没有反应
fsmc hal初始化程序
void MX_FSMC_Init(void)
{
  FSMC_NORSRAM_TimingTypeDef Timing = {0};
  FSMC_NORSRAM_TimingTypeDef ExtTiming = {0};

  /** Perform the SRAM1 memory initialization sequence
  */
  hsram1.Instance = FSMC_NORSRAM_DEVICE;
  hsram1.Extended = FSMC_NORSRAM_EXTENDED_DEVICE;
  /* hsram1.Init */
  hsram1.Init.NSBank = FSMC_NORSRAM_BANK4;
  hsram1.Init.DataAddressMux = FSMC_DATA_ADDRESS_MUX_DISABLE;
  hsram1.Init.MemoryType = FSMC_MEMORY_TYPE_SRAM;
  hsram1.Init.MemoryDataWidth = FSMC_NORSRAM_MEM_BUS_WIDTH_16;
  hsram1.Init.BurstAccessMode = FSMC_BURST_ACCESS_MODE_DISABLE;
  hsram1.Init.WaitSignalPolarity = FSMC_WAIT_SIGNAL_POLARITY_LOW;
  hsram1.Init.WrapMode = FSMC_WRAP_MODE_DISABLE;

  hsram1.Init.ExtendedMode = FSMC_EXTENDED_MODE_ENABLE;
  hsram1.Init.AsynchronousWait = FSMC_ASYNCHRONOUS_WAIT_DISABLE;
  hsram1.Init.WriteBurst = FSMC_WRITE_BURST_DISABLE;
  /* Timing */
  Timing.AddressSetupTime = 0x01;
  Timing.AddressHoldTime = 0x00;
  Timing.DataSetupTime = 0x0f;
  Timing.BusTurnAroundDuration = 0x00;
  Timing.CLKDivision = 0x00;
  Timing.DataLatency = 0x00;
  Timing.AccessMode = FSMC_ACCESS_MODE_A;
  /* ExtTiming */
  ExtTiming.AddressSetupTime = 0x15;
  ExtTiming.AddressHoldTime = 0x15;
  ExtTiming.DataSetupTime = 0x05;
  ExtTiming.BusTurnAroundDuration = 0x00;
  ExtTiming.CLKDivision = 0x00;
  ExtTiming.DataLatency = 0x00;
  ExtTiming.AccessMode = FSMC_ACCESS_MODE_A;

  if (HAL_SRAM_Init(&hsram1, &Timing, &ExtTiming) != HAL_OK)
  {
    Error_Handler( );
  }

  /** Disconnect NADV
  */

  __HAL_AFIO_FSMCNADV_DISCONNECTED();

额，解决了，是编译优化的问题，cubemx生成的是-3，改成0就好了

慢慢懂

大佬你好，我也是这个型号的液晶。FSMC—TFTLCD显示实验中我也修改了宏定义了的。但是我的液晶显示依然是黑屏，用的是它的程序，就改了液晶型号。您知道为什么吗
