Posted on November 11, 2013 at 14:18I have just ported one of my systems over to the STM32F4Discovery board. It is a small OS + TCP/IP. However, I stumbled on a few things: I need to have a 8 khz interrupt for audio sampling. I think I have clocks O...
Posted on October 03, 2013 at 21:20Hi Folks We are porting a complex algorithm from the PC into the STM32F407 and we are testing it on a large test file (15000 items long) which I have include in a .h file in the form const int testdataA[15000] = { ...
Posted on November 08, 2013 at 17:12Hello everyone, I have a product based on an STM32 and a SPI flash NOR memory. I store some data inside the flash NOR, then I read them back through USB. Sometimes (very rare, but happens ..), I get a few corrupte...
Posted on August 21, 2012 at 04:45Hello, I am have been using an external SRAM with the STM32F207. The SRAM I am using is the Cypress CY62167EV30, a 16-Mbit ( 1M x 16 / 2M x 8 ). The SRAM is used to store a captured image and allow for manipulation...
Posted on November 11, 2013 at 20:46I have fried 2 of my 3 stm32F4 discovery boards. Before I even touch the third one I want to understand more about the power subsystem in these devices. I've been reading the datasheets (for the chip, the ref man...
Posted on November 11, 2013 at 09:21HiI have a STM32F4Discovery evaluation board. I use CooCox CoIDE and GNU Tools ARM Embedded. While everything works fine if I use standard peripheral library and code, I cannot run anything that is dsp related (li...
Posted on November 10, 2013 at 00:52Hi Forum, I need to determine if the IWDG has timed out. After the board resets, can I determine this by checking a flag e.g. if (RCC_GetFlagStatus(RCC_FLAG_IWDGRST) != RESET) // IWDG has reset or if I know that...
Posted on July 13, 2012 at 12:31Hello,I am trying to get some basic I2C communications going between the STM32F100 and a sensor so I thought Application Note AN2824 would be a good starting point. But I can't find the associated firmware files. All ...
Posted on November 11, 2013 at 10:58Hi to everybody, I need informations (or examples) about how to configure the TIMs in order to trigger its slaves. The documentation inside the reference manual is not clear. Can somebody help me please. Thank you
Posted on November 07, 2013 at 15:33Hi,I was going through table 14 of STM32F050xx datasheet. This table shows IDD-VBAT at various voltages. Just want to check when this measurement is taken whether VDD was pin was floating or grounded? #stm32f0...
