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...
Posted on September 06, 2013 at 11:21I am using the sample application Audio playback and recording available along with the STM32F4 evaluation kit. The sample application will save the recorded file to USB memory stick. Currently we are using this ...
Posted on January 28, 2014 at 15:56 Hello. I have serious problems getting the STM32F429I-DISCO board to work either in USB Host or Device mode. Now I'm trying to get audio example from USB library v2.1.0 to work but when I use internal DMA mode...
Posted on May 10, 2011 at 16:50I'm trying to get flow control working on Uart1 on the discovery board and am seeing some odd behavior. I have a little test program that receives 10 characters, pauses, and then echos them back. At the host (linux)...
Posted on March 04, 2014 at 12:59Hi , I am about to draw the schematics of a card which has STM32F405RG on it. I want to program my card throug SWD port. I made the pin connections as I described below: NRST: pulled up to VDD with 100K SWDIO: pull...
