Posted on May 27, 2014 at 07:03After I plugged in the keyboard, the ConnSts always return a value that tells the MCU nothing is connected. All my keyboards (3 of them) are fine. I've properly connected DM & DP (PA11&12). I've connected PA9 to Vbus l...
Posted on April 09, 2014 at 17:09 Hi all, I have been trying to configure TIM12 to work in OnePulse mode and I am not able to accomplish that. With elder version of device drivers I was able to achieve what I needed in such a way: ...
Posted on May 26, 2014 at 06:01Hi all,Using cube4.2.0 and STM32F205:I am trying to use SDIO in DMA mode.Polling mode work perfectly, but using ''HAL_SD_ReadBlocks_DMA()'' times out.I have traced that ''SDIO_IRQHandler()'' fires and sets the ''hsd->S...
Posted on May 25, 2014 at 04:25My STM32F429 seems to be stuck in a lockup state. When I start the debugger in TrueSTUDIO, it halts in startup_stm32f429.s at the second instruction in the Reset_Handler. I'm unable to step through the code at all. I t...
Posted on May 16, 2014 at 14:32Hi,I am working on a project that involves programming a smart card and reading it to some data.I would like to know the most suitable way to do this using STM32 Cortex M4 boards. Are there any support interface for th...
Posted on May 26, 2014 at 13:36Hello, Is there any flash tool for linux (or windows) over CAN-bus? STM32F105 is capable to boot from CAN-bus but I didn't find any tool for that. What is the best way to boot the chip from system memory without acces...
Posted on May 26, 2014 at 15:55Hi, I have had an error in my program and was wondering why the assertion macro did not give a warning for the second line, the first line is correct: RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM2, ENABLE); RCC_APB2Periph...
Posted on May 26, 2014 at 15:12Hi everyone, I'm very new to the world of MCUs and would be grateful is someone could give me a brief outline as to how to use the DMA to read values from the ADC and store them in a buffer, then have the processor mod...
Posted on July 08, 2013 at 14:05When trying to run the LSE oscillator (at 32.768kHz), I stumbled upon the following problem: PWR->CR |= PWR_CR_DBP; // disable backup-domain lock RCC->BDCR = RCC_BDCR_LSEON; // enable 32.768kHz oscillator did not ...
Posted on May 26, 2014 at 18:06Hi everyone, I'm trying to read data from light-to-digital sensor using I2C with stm32f4-discovery I've been through too much problems at the end I just need a working example for a specific sensor, I mean I need an ex...
