Posted on April 22, 2015 at 18:56I'm using STM32Cube with stm32f103RB mcu.I tried to create a simple test project and run into couple of issues. 1) I have configured project for external clock source (8 MHz) and made HCLK equal to 72 MHz. I checked ...
Posted on April 22, 2015 at 18:55We're developing for the STM32 and want to use the Visual Studio 2012 and NETMF 4.3. Where do we find the latest tinybooter, etc files for the ST boards that are compatible with 4.3. When deploying, the compiler comp...
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...
Posted on July 11, 2012 at 00:52Hi, I have a problem with interfacing OV7670 camera. I connect only 4 wires from Ov7670 to my stm32f4board, SIO_C, SIO_D, 3V+ and GND. Then I tried to read product id of the camera. It always send 0xFF. I am n...
Posted on April 08, 2014 at 04:11 Guys, I have OV7670 module and STM32 dev board, I'm confused on how to connect the port of STM32 and OV7670 at the module because of the name of the port on OV7670 is different with in STM32 code, ...
Posted on April 17, 2015 at 12:48Hello again! I would like to make a question about an issue I have with the measurements of three currents! Specifically I have a 3-phase converter and I would like to measure its currents as fast and accurate as pos...
