如题，没有使用F7自带的LCD驱动，屏是4.3寸，480*272，使用FSMC驱动SSD1963，配置SSD1963的时钟已经最大，测试了一下，单纯刷屏，刷屏时间大约为90多毫秒，FSMC配置如下
void MX_FMC_Init(void)
{
FMC_NORSRAM_TimingTypeDef Timing;
FMC_NORSRAM_TimingTypeDef ExtTiming;
/** Perform the SRAM1 memory initialization sequence
*/
hsram1.Instance = FMC_NORSRAM_DEVICE;
hsram1.Extended = FMC_NORSRAM_EXTENDED_DEVICE;
/* hsram1.Init */
hsram1.Init.NSBank = FMC_NORSRAM_BANK4;
hsram1.Init.DataAddressMux = FMC_DATA_ADDRESS_MUX_DISABLE;
hsram1.Init.MemoryType = FMC_MEMORY_TYPE_SRAM;
hsram1.Init.MemoryDataWidth = FMC_NORSRAM_MEM_BUS_WIDTH_16;
hsram1.Init.BurstAccessMode = FMC_BURST_ACCESS_MODE_DISABLE;
hsram1.Init.WaitSignalPolarity = FMC_WAIT_SIGNAL_POLARITY_LOW;
hsram1.Init.WaitSignalActive = FMC_WAIT_TIMING_BEFORE_WS;
hsram1.Init.WriteOperation = FMC_WRITE_OPERATION_ENABLE;
hsram1.Init.WaitSignal = FMC_WAIT_SIGNAL_DISABLE;
hsram1.Init.ExtendedMode = FMC_EXTENDED_MODE_ENABLE;
hsram1.Init.AsynchronousWait = FMC_ASYNCHRONOUS_WAIT_DISABLE;
hsram1.Init.WriteBurst = FMC_WRITE_BURST_DISABLE;
hsram1.Init.ContinuousClock = FMC_CONTINUOUS_CLOCK_SYNC_ONLY;
hsram1.Init.WriteFifo = FMC_WRITE_FIFO_DISABLE;
hsram1.Init.PageSize = FMC_PAGE_SIZE_NONE;
/* Timing */
Timing.AddressSetupTime = 2;
Timing.AddressHoldTime = 15;
Timing.DataSetupTime = 8;
Timing.BusTurnAroundDuration = 15;
Timing.CLKDivision = 16;
Timing.DataLatency = 17;
Timing.AccessMode = FMC_ACCESS_MODE_A;
/* ExtTiming */
ExtTiming.AddressSetupTime = 2;
ExtTiming.AddressHoldTime = 15;
ExtTiming.DataSetupTime = 4;
ExtTiming.BusTurnAroundDuration = 15;
ExtTiming.CLKDivision = 16;
ExtTiming.DataLatency = 17;
ExtTiming.AccessMode = FMC_ACCESS_MODE_A;
HAL_SRAM_Init(&hsram1, &Timing, &ExtTiming);
}
不知各位各位使用SSD1963刷屏480*272需要多呈时间？ |
