The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Posted on July 01, 2014 at 15:51Hi, here's the problem: When I used RS232, I could reset my target, reset my PC app, and get going again, as the new bytes I sent went to the target. But this doesn't work over VCP. When the target is reset, the devic...
Posted on July 01, 2014 at 14:58 hi,all I'm using two stm32f103 for dma spi both master and slave. I enable one gpio for external interrupt on the master side for slave inform of PTX. But somehow theEXTI15_10_IRQHandler keep triggered afte...
Posted on June 30, 2014 at 10:27We've designed a USB board based on an STM32F437 microcontroller, associated to an SMSC-USB3370 ULPI device clocked by a 60MHz external oscillator. We are facing an issue with the USB enumeration as our board is reco...
Posted on July 01, 2014 at 09:01 Hi, I'm developing with STM32F0 and I have a problem with interrupt. this is my code: void batchStandByConf(void){ EXTI_InitTypeDef EXTI_InitStructure; //PC10 input GPIOC->OSPEEDR |= GPIO_OSPEEDER_OSPEE...

Posted on June 30, 2014 at 22:08Hi.I use a STM32F103ZE microcontroller.I try to change the System Clock (default is HSI) to HSE.On my board is a HSE - cristal oscilator which value is 8 Mhz and i want to change it to 72 Mhz and it works.But if i wan...
Posted on June 27, 2014 at 14:43Hi; I recently noticed the STM32L family, while I already took a closer look at (and worked with) the STM32F family. At first glance it seemed to me that the STM32L05xxx are pin compatible with the STM32L05xxx. So her...
Posted on June 29, 2014 at 22:48Many years ago i asked here if ST will do STM32 in other packages like DIP , SOnow i ask again. It would be very nice to have a F401 in a SO16 for instance.MKE04Z8VWJ4 is available in SO and NXP have 8pin DIP's!
Posted on June 30, 2014 at 17:42Hi all, I would like to know where can i find the internal driving circuit schematics of a TTa output pin (PA0, pin 14) for the STM32F373RC controller. PS: I think i might be an open collector with an internal pull u...
Posted on June 30, 2014 at 02:32Can I have a link or an code example to count the rising edges that have an input signal in a prefixed time?I need the number of rising edges in a second.The frequency of the signal on a gpio input is in a range from ...
