Posted on June 23, 2012 at 21:57Hi All! I´ve been working on a project that uses OV7740 omnivison sensor But I´m quite unable to configure it properly. Have anyone used it yet, to help me trough the hard steps of configuring its registers, and all.
If anyone have some information or a configuration software tool for OV sensors I´d really appreciate.
I´m using a STM32F407 to attach it, currently the config for the DCMI is as follows:
/* DCMI configuration */
DCMI_InitStructure.DCMI_CaptureMode = DCMI_CaptureMode_Continuous;
DCMI_InitStructure.DCMI_SynchroMode = DCMI_SynchroMode_Hardware;
DCMI_InitStructure.DCMI_PCKPolarity = DCMI_PCKPolarity_Rising;
DCMI_InitStructure.DCMI_VSPolarity = DCMI_VSPolarity_High;
DCMI_InitStructure.DCMI_HSPolarity = DCMI_HSPolarity_High;
DCMI_InitStructure.DCMI_CaptureRate = DCMI_CaptureRate_All_Frame;
DCMI_InitStructure.DCMI_ExtendedDataMode = DCMI_ExtendedDataMode_8b;
I set an iterrupt for frame capture and it´s triggering, but the data on DMA address is all messed up. I´m unsure what should I do. Many thanks!
