Hello all,
I'm facing an issue with STM32 CubeMX / CubeIDE firmware using this display with X-CUBE-DISPLAY over FMC.
Each time I'm trying to initialize the LCD this function if((ILI9341_LCD_Driver.ReadID(LcdCompObj, &id) == ILI9341_OK) && (id == ILI9341_ID)) is always returns id = 0x0.
I've tried to play with timings, using formula from FMC/FSMC, but no luck.
This is my FMC initiliaztiation:
/* FMC initialization function */
static void MX_FMC_Init(void)
{
/* USER CODE BEGIN FMC_Init 0 */
/* USER CODE END FMC_Init 0 */
FMC_NORSRAM_TimingTypeDef Timing = {0};
/* USER CODE BEGIN FMC_Init 1 */
// hsram1.Instance = FMC_Bank1_1;
/* USER CODE END FMC_Init 1 */
/** Perform the SRAM1 memory initialization sequence
*/
hsram1.Instance = FMC_NORSRAM_DEVICE;
hsram1.Extended = FMC_NORSRAM_EXTENDED_DEVICE;
/* hsram1.Init */
hsram1.Init.NSBank = FMC_NORSRAM_BANK1;
hsram1.Init.DataAddressMux = FMC_DATA_ADDRESS_MUX_DISABLE;
hsram1.Init.MemoryType = FMC_MEMORY_TYPE_SRAM;
hsram1.Init.MemoryDataWidth = FMC_NORSRAM_MEM_BUS_WIDTH_8;
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_DISABLE;
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_ENABLE;
hsram1.Init.PageSize = FMC_PAGE_SIZE_NONE;
/* Timing */
Timing.AddressSetupTime = 2;
Timing.AddressHoldTime = 15;
Timing.DataSetupTime = 16;
Timing.BusTurnAroundDuration = 2;
Timing.CLKDivision = 16;
Timing.DataLatency = 17;
Timing.AccessMode = FMC_ACCESS_MODE_A;
/* ExtTiming */
if (HAL_SRAM_Init(&hsram1, &Timing, NULL) != HAL_OK)
{
Error_Handler( );
}
/* USER CODE BEGIN FMC_Init 2 */
/* USER CODE END FMC_Init 2 */
}
My CPU is running at 216MHz and I've tried with these parameters:
And nothing.
I've recheck the connections, I replaced the LCD with another one (both of them are working on F103 without FMC or on ATMEL).
Can somebody help me to fix this issue?
Thanks.
