Posted on October 03, 2013 at 04:13Hi, I'd kindly ask if anyone can point me to robust uart example, possibly with interrupts, dma and hardware flow control... I also wonder how flow control affects other code and functions ? Thanks in advance, rega...
Posted on July 05, 2013 at 15:12Hi,I didnt find nothing in the datasheet refering the data update rate of the calculations that STPM01 do. Do any one knows? I gues that it is 16,66ms but I am no sure.Bye
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 November 12, 2013 at 10:37Hello I've got evaluation board STEVAL-ILL015v1 and I want to load firmware supplied by ST on it. I downloaded package with firmware from ST site and inside that package are 2 files with extensions: .d79 and .sim...
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...
