FreeRTOS httpserver connet with DAM

Posted by HS.Lee on April 14, 2012
Dear all:

My program was modify from ST official httpserver_netconn. Now it can connected with my iPad, then I try to compile with my CMOS sensor subroutine. (CMOS sensor subroutine can works.) Finally, I want show the image on web browser.

Tragedy was happened.
It can not responses my web request, and keeps in CMOS sensor action.
Dose anyone has any suggestion? Please help, give me some advice. In the end how to do it more correct.

The below is parts of my program.

int main(void)
{

SRAM_Init();
Reset_OV9655_Config();//reset OV9655
LCD_LED_Init(); /*Initialize LCD and Leds */
ETH_BSP_Config(); /* configure ethernet (GPIOs, clocks, MAC, DMA) */
LwIP_Init(); /* Initilaize the LwIP stack */
http_server_netconn_init(); /* Initialize webserver */

#ifdef USE_DHCP
xTaskCreate(LwIP_DHCP_task, "DHCPClient", configMINIMAL_STACK_SIZE, NULL,DHCP_TASK_PRIO, NULL); /* Start DHCPClient */
#endif
xTaskCreate(ToggleLed4, "LED1", configMINIMAL_STACK_SIZE, NULL, LED_TASK_PRIO, NULL);/* Start toogleLed4 task : Toggle LED4 every 250ms */

xTaskCreate(DCMI_OV9655_Start, "DCMI_OV9655_Start", configMINIMAL_STACK_SIZE, NULL, DCMI_TASK_PRIO, NULL);

/* Start scheduler */
vTaskStartScheduler();

/* We should never get here as control is now taken by the scheduler */
for( ;; );

}


void DCMI_OV9655_Start((void * pvParameters)
/* Configures the DMA2 to transfer Data from DCMI to the LCD ****************/
/* Enable DMA2 clock */
RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_DMA2, ENABLE);

/* DMA2 Stream1 Configuration */
DMA_DeInit(DMA2_Stream1);

DMA_InitStructure.DMA_Channel = DMA_Channel_1;// in reference maual only DMA2_Stream1/Channel1 can for DCMI function
DMA_InitStructure.DMA_PeripheralBaseAddr = DCMI_DR_ADDRESS;
DMA_InitStructure.DMA_Memory0BaseAddr = FSMC_LCD_ADDRESS;
DMA_InitStructure.DMA_DIR = DMA_DIR_PeripheralToMemory;
DMA_InitStructure.DMA_BufferSize = 100;//BufferSize = 1 by PeripheralDataSize_Word(32b) =32b=4B=2pixel. means 4byte transfers one time
DMA_InitStructure.DMA_PeripheralInc = DMA_PeripheralInc_Disable;//external address increase disable
DMA_InitStructure.DMA_MemoryInc = DMA_MemoryInc_Disable; //RAM address increase disable
DMA_InitStructure.DMA_PeripheralDataSize = DMA_PeripheralDataSize_Word;
DMA_InitStructure.DMA_MemoryDataSize = DMA_MemoryDataSize_HalfWord;
DMA_InitStructure.DMA_Mode = DMA_Mode_Circular;//DMA_Mode_Normal ;
DMA_InitStructure.DMA_Priority = DMA_Priority_High;
DMA_InitStructure.DMA_FIFOMode = DMA_FIFOMode_Enable;
DMA_InitStructure.DMA_FIFOThreshold = DMA_FIFOThreshold_Full;
DMA_InitStructure.DMA_MemoryBurst = DMA_MemoryBurst_Single;
DMA_InitStructure.DMA_PeripheralBurst = DMA_PeripheralBurst_Single;

DMA_Init(DMA2_Stream1, &DMA_InitStructure);
}

I forgot to say, that my platform is STM32F207.
Friends please provide me some advice. Very grateful.

“My program was modify from ST official httpserver_netconn.”


Sorry, I cannot support other peoples code.

“Friends please provide me some advice.”


If you have a problem with ST code, ask on an ST forum.

Regards.

Dear Richard:

Thanks for your kindly reply.
Ok, I will try it by myself.

Best regards,

Simon
