I'm now trying to receive an image from my OV9655 over the DCMI port and send it then to the pc. With low resolution (160x120 pixel) and saving the image in the ram it worked good. Now I want to geht higher r...

Hi
I've some problems with the dcmi interface from my stm32f4 I've initialized the module for line and frame interrupts, but in debug I see only the frame complete interrupt, and a line count variable...
Posted on October 23, 2013 at 17:22Hi all I've a little problem. I use the USB driver from st to communicate with my STM32F4-Discovery. This works realy good. But I've would make a streaming protocol with a camera sensor. For this I have to use the ...

Hi all
I've a question: How does I have to configure the systick timer to operate without interrupts and so I can check the count value...
I've tried this, but if I check if SysTick-VAL < 480 or <...
Posted on May 16, 2013 at 16:10Hi all I've some troubles with the internal temperatur sensor from my stm32f051: If I read the adc_channel16 I get ~1920 as value. Then I calculate the result in this way �C = ((V25 - VSENSE) / Avg_Slope) + 25 = ((1.43...

This gets also a Hardfault:
volatile
uint16_t DCMI_Buffer[160 * 60] = {0};
volatile
uint32_t line = 0;
void
DMA2_Stream1_IRQHandler(
void
){
if
(DMA_GetITStatus(DMA2_Stream1, DMA_IT_HTIF1) != RESET){
/...

No, the code above works fine, but why?
this results in a hard fault:
volatile
uint16_t DCMI_Buffer[160*60];
DMA_InitStructure.DMA_BufferSize = (160 * 60);
And this works:
vola...

Here is the camera initialization:
volatile uint16_t DCMI_Buffer[160 * 120] = {0};
void DCMI_Config(void)
{
DCMI_InitTypeDef DCMI_InitStructure;
GPIO_InitTypeDef GPIO_InitStructure;
DMA_InitTypeDef DMA_...
