Posted on November 26, 2014 at 15:54Hi All, I am having stm32f4discovery board with stm32f407vg processor and i am new to stm32f4 & also embedded programming. i tried delay using normal delay loop function calling method but i need to check timer i...
Posted on November 26, 2014 at 16:51I used JFlash to program the bootloader & application FW into STM32F103RC on board via Jlink.'Secure chip' was enable. The unit is able to upgrade the application FW via USB and this worked fine. The bootloader re...
Posted on November 21, 2014 at 15:55Hi all Here the scenerio is DMA updating the timer and timer update trigerring the DAC At the starting of the program DAC_buffersize is 158 ..that is ok I am able to see the DAC_OUT increment in the scope . but wh...
Posted on November 26, 2014 at 11:44Hi,I'm working on hardware with a stm32f105. It has the USART1 connected to the usb port, and I need to create a VCP to send and receive data from a PC. Is there any example that can help me? Can anyone tell me ho...
Posted on January 25, 2014 at 21:34Hi, I am trying to sample some data using DMA and the internal ADC and send the same data , still using DMA to an external DAC using the SPI Internface, through an optoisolation barrier. It all works great, I need ...
Posted on November 25, 2014 at 16:58Hi,I need to have the STL (Self Test Library) to make a certain project IEC 60730 and 60335 compliant, but as of yet I have not found the library. My reference is AN4435. Does anyone know how I can get this for th...
Posted on November 21, 2014 at 06:04Hi AllI am using the freeRTOS WIN32 simulator to code most of my OS-dependent functions, but the target is STM32F4 (it is a lot easier debugging early code using VS)I am using CMSIS for the STM , but I must use th...
Posted on October 17, 2014 at 09:36I am using the STM32CubeMx version 4.3.1 and inside the clock configuration page, the PCLK2 is used for USART1CLK. It shows 2.097. However, in HAL_RCC_GetPCLK2Freq function, the return value was 2.000. This caused ...
Posted on November 23, 2014 at 17:39STM32F407 datasheet says max fsmc clk = 60MhzFSMC_CLKDivision = 2; // 168/2 = 84MhzFSMC_CLKDivision = 3; // 168/3 = 56MhzSo what is CLKDivision for 60MHz? ?? #fsmc-clk
Posted on November 24, 2014 at 18:03 Using STM32Cube_FW_F4_V1.3.0 and a GCC 4.7.4 toolchain I built on Mac OS X, the attached demo (based on Projects/STM32F429I-Discovery/Examples/BSP) toggles one of the LEDs every 250 ms and the other every 500...
