Posted on October 29, 2013 at 08:43 Hi, I am trying to receive datas from a camera module through DCMI interface and send each 8bits received to UART. The problem is that I can only receive one word (NDTR=1) and the program only enters the DM...
Posted on September 28, 2013 at 18:03 Hi, I have a long configuration to be done through I2C interface, so I thought I have to do it using DMA.I am trying to read device ID as a start. The problem is that the I2C sequence doesn't reach the...
Posted on September 25, 2013 at 13:01Hi,I want to receive datas from DCMI interface and then transfer it to UART interface through DMA.To do that, I am plannig to receive each Byte from the DCMI interface store it into a buffer using DMA and then tr...
Posted on September 23, 2013 at 11:19 Hi, I am trying to establish I2C communication between STM32F4 and OV5642 Camera module( http://www.arducam.com/camera-modules/5mp-ov5642/) and I want to test it separately. I already worked with I2C a...
Posted on September 12, 2013 at 20:27Hi,I am trying to interface the OV5642 camera module with the STM32F4 microcontroller. So I wanted to ask about the XCLK signal in the camera, should it stay NC, or should I connect it to a clock (10Mhz to 24Mhz ...
