Posted on April 13, 2015 at 19:57Noticed an ''interesting'' issue that I was unable to trackdown.If I compile the example LwIP_UDPTCP_Echo_Server_Netconn_RTOS using IAR 7.40 everything works fine YET when I compile the same code using IAR 6.50 I get...
Posted on April 22, 2015 at 04:58Hello everyone, I checked the data sheet but couldn't find an answer to the following question: What should happen if master initiates transmission but slave is detached or powered down? In my tests once master...
Posted on April 22, 2015 at 23:49 Hi everyone, I am getting problem with my SPI first bit received from slave. I have 2 boards as master and slave. The SPI is configured as 8 bit full duplex mode, soft NSS, receive interrupt at slave. ...

Posted on September 26, 2014 at 01:41I am trying to use the CPAL library for I2C communication for the F0 MCU. This download page seems to suggest that the std peripheral library include CPALv2. But when I use it, the User manual does not seem to ...
Posted on April 21, 2015 at 08:32The reference manaul for the STM32F411 series says that for a CPU running at 100MHz on a 2.7-3.6 supply voltage, the flash latency should be 3 wait cycles. However, the CMSIS startup file (system_stm32f4xx.c v1.5.0...
Posted on April 22, 2015 at 17:02Hi everyone, I'm trying to program the SPI2 of my STM32 to only transmit data at 18Mbit/s as I saw on datasheet. My problem is to configure the ''SPI_HandleTypeDef'' in order to use the function : HAL_StatusTypeDe...
Posted on May 24, 2013 at 07:54Hi, I want to interface the OV7670 FIFO omnivision camera with STM32F4discovery board I have used an example inside of STM32F4xx_DSP_StdPeriph_Lib_V1.1.0, the example drives an OV2640/9655 camera so I changed the regi...
Posted on November 20, 2013 at 15:14Hi everybody,I'm starting working with image sensors and there is something I don't understand.ST provides a digital camera interface called DCMI. I saw some people are using it OV7670 or OV5642. But in the sensor...
Posted on March 06, 2014 at 10:42I want to use STM32F407 with the OV7670 camera. I need to external 10 MHz clock source.SystemCoreClock 168 MhzAHB Prescaler 1, ABP1 Prescaler 4, ABP2 Prescaler 2Can I get 10 Mhz clock using Timer 3. #stm32f407 #pw...
