Posted on January 26, 2013 at 16:19Hi all, I've had great difficulties setting up my own STM32F405 board and having it actually run, but finally I've succeeded booting it and programming it from my stm32f4Discovery. However I have a very strange b...
Posted on October 04, 2013 at 16:00Hi All, i'm using STM32F407, USB Device library V1.1.0 / 19-March-2012, i'm able to receive from PC to STM bytes using CDC, but i'm unable to send to PC from STM :( i modified function like this : static uint16_...
Posted on October 04, 2013 at 11:13I have found working solution. But for me it look ugly.uint8_t command = 0x55; uint16_t u16Temp = 0; u16Temp = GPIO_ReadOutputData(GPIOA)&0xFF00; u16Temp |= command; GPIO_Write(GPIOA, u16Temp); Is there better way ...
Posted on October 02, 2013 at 11:24Hi all,I probably made a mistake in my first layout for STM32F103RE (LQFP64), with SDIO bus. My 400 KHz SDIO_CLK output is not consistent on oscillo : I see variations in the levels of the HIGH and LOW that vary wi...
Posted on July 18, 2012 at 19:59 Hi Friends from ST and dear fellows. I'm using STMStudio with yagarto toolchain and STLIB with the STM32F4Discovery. Up to release 2.2 of STMStudio I was able to import any global variable avaliable from inside...
Posted on October 03, 2013 at 17:15 Hi, I developed an application using the STM32L152D Evaluation board and everything was working as expected. The application was then moved to the actual project which uses a STM32L151RD microcontroller...
Posted on October 03, 2013 at 09:50Can I configure two usart's to use one DMA? In datasheet there is table called ''DMAx request mapping'' and for stm32f40/1/2/3 eg. UART4 uses channel 4 for RX and TX DMA trigger on stream 2 and 4. Can I configure s...
Posted on October 04, 2013 at 04:46Hi, I'm trying t owrite robust code for USART communication with embedded modem like module. Since communication is not strict command-response manner, but module can send messages also in asynhrounous manner (spor...
Posted on September 20, 2013 at 17:30Hello, I am using a STM32F407. My application needs both USART1 and USART6 to concurrently receive data. I would like to use DMA2 to transfer data received from each USART to external RAM via the FSMC and ensure...
Posted on September 30, 2013 at 13:14 hello all and thanks for your help, I'm working with stm32f4 discovery board and I will like to use two different timers. For the timer TIM3 after a long work I set certain parameters so I can have my des...
