Posted on March 13, 2012 at 17:51 If I let run this DMA interrupts, without a while looop on the line 64 I get only first word transmitted. With a while loop it is always OK.What's wrong? void dma_tx(uint16_t *rxbuf, uint16_t *txbuf, uint16_t ...
Posted on March 14, 2012 at 09:53 Greetings, I had read something about a Matlab/Simulink example in late 2011 for STM32F4 in an official presentation.How much time is left? In an approximately way... Thanks in advance.
Posted on March 12, 2012 at 15:21 I have a following code to initial SPI3 communication. The code below causes a HardFault and I am still not able to find the reason:( void spi_init(void) { DMA_InitTypeDef DMA_InitStructure; SPI_...
Posted on March 13, 2012 at 11:33Dear all,I would like to know that the API functions in the STM32 Peripheral library are thread-safe or not. I want to use them with the RTOS. Do I have to protect them with the Mutexes of the RTOS?Best Regards.Pornp...
Posted on March 12, 2012 at 13:02Is there any conflict with using sleep mode on the STM32F4 by means of the __WFI() call when using the RTX RTOS? The only reason I ask is because whenever I call it, it seems to not reduce power nearly as much as wh...
Posted on March 09, 2012 at 20:17Hi, Is there anyones out there using Sourcery CodeBench Lite for STM32F4xx? We've been using this one for STM32F10x series for a while. There is no problems for us untill we start using floating point instructions on...

Posted on March 09, 2012 at 12:29I have a hid report created using descriptor tool 2.4. The final descriptor size is 289. which appears to be to large (hid not detected). If I cut a few reports out so the size becomes less than 256 it works fine. Is...
Posted on March 10, 2012 at 14:09I use SPI1 and it work well,when i try to use the SPI2 it dont work. The SPI2 clock is not generated ,i think i don't need addional initialization but i could be wrong . What am i missing here? It's quite frustratin...
