Posted on March 06, 2014 at 04:44hello everyone today I have problem with memory but I cannot solve I don't know it relate stack and heap or not. in startupcode file, I initialize stack_size : 0x00013000 and heap_size : 0x00006000 because I read on ...
Posted on March 04, 2014 at 17:15hello everyone, I have problem about memory I download source code ''better string lib'' and I just add 3 C file to project, when I built no error happen, but I want to know exactly result then I debug, and program n...
Posted on March 04, 2014 at 13:59Hello, We use STM32Fxx MPU in many projects. During the developmentof new equipment with STM32F427, we have run into this problem:We useSPI4, which is controlled by the DMA. Streamer DMA2_Stream1 is used for sending,...
Posted on March 05, 2014 at 15:52Hi guys. I know some of you guys have done something like this. I would like to implement the TIM1 to generate a clock, using it as a PWM out-up mode, but I wish ( if it is possible) modify its functioning to generat...
Posted on March 05, 2014 at 00:23Hi all,I saw many examples using systick interrupt handler to generate the accurate delay time (like the example below). My question would be pretty simple here: why does ''http://www.keil.com/pack/doc/cmsis/Core/h...
Posted on March 05, 2014 at 01:44It's ESD season once again. I have been getting far too many STM32-F407 TQPF IC's being blown up. I believe ESD is the culprit. Failure mode is a bit used as an input is blowing out the internal pullup or that what i...

Posted on May 27, 2013 at 10:17Hi guys,does anyone have a working Peripheral Library documentation for the STM32F4xx. The one I downloaded from the STM Homepage is now working. I can open it, I see the index and the structure, but I don't see any do...
Posted on March 05, 2014 at 11:32Hey everybody, Is it somehow possible to start/enable/trigger a DMA transfer with the help of another DMA transfer? I'm thinking of the following scenario: - DMA transfer 1 is timer triggered (every 1us) and transfer...
