Posted on July 01, 2014 at 18:09Since there is no function for the stm32f30 series like send7bitslaveaddress which is there for other series when do I check the NACK flag in case the slave is not present? The sending of the slave address seems to ha...
Posted on June 28, 2014 at 21:01Hi, I'm looking for a means which lets me save a text file on a USB key from a variable that can be found in my program. . I work with a STM32F4 (KEIL compiler) Does someone can help me to find a solution? Thank you...
Posted on July 01, 2014 at 13:11hi,I'm using LCD with stm32f107 vct6, I need 5V for backlight.I configure GPIOC_Pin7 as GPIO_Mode_Out_OD and I connect it with 4K7 resisator and 5V.GPIOC_Pin7 -------->-------->OUT 4K7 ^ ^...
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...
