Posted on July 01, 2014 at 06:29STM32F101R8 is running at 36MHz off its internal clock. One of its three general purpose timers, TIM4, aims to generate four different time based interrupts. These should be proper internal time base design, without a...
Posted on July 01, 2014 at 17:06Hi, In AN2606 I read STM32F429xx/439xx can have bootloader V7.x or V9.x. but I don't find information (for exemple in DM00068628 STM32F42xx and STM32F43xx Errata sheet). Does the version depend of the date of manufa...
Posted on July 01, 2014 at 17:44Hi, a colleague and I have the order to implement a CAN bootloader to our application. We are using the STM32F207ZG and we would like to use the internal CAN bootloader. After a lot of starting problems we've manage...
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 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...
