Posted on November 04, 2012 at 10:25Hello, I am experiencing some troubles recently with floating point calculation within interrupts. I have a dma interrupt running at 400 Khz in double buffer mode. I have an usart RX interrupt coming at 50 Hz. the...
Posted on November 08, 2012 at 15:51I see that there are dedicated forums for some of the STM32 Discovery boards, such as the Discovery-F4. Will there be a dedicated forum for the Discovery-F3? The dedicated forums are a little hard to find because ...
Posted on June 06, 2012 at 15:59Hi,I'm working on a custom design with in a STM32F4xx. A 420mF capacitor is connected to Vbat. ( with a serial diode and a resistor between Valim and Vbat to charge up the supercapacitor ).The system power off it stil...
Posted on November 08, 2012 at 16:52can't install drivers under windows 8, the ''unsigned driver '' error appears. workarounds with reboot to troubleshoot menu does not work because there is no such menu in full version (not dev. preview). is there ...
Posted on November 12, 2012 at 18:47Greetings - Seek the higher performance (faster downloads) achievable w/J-Link ''SWD'' rather than the ''on-board'' ST-Link. Reviewed the F4 Discovery schematic - does not appear that there is any easy way to ''b...
Posted on November 12, 2012 at 18:41 I want to edit and use the example of EXTI PA3, but it does not work, what am I doing wrong? void Exti_Config(void) { EXTI_InitTypeDef EXTI_InitStructure; GPIO_InitTypeDef GPIO_InitStructure; N...

Posted on November 12, 2012 at 10:27Hi all, I have a pressure sensor whose the impedance is in the range [1400W 3000W]. I would understand and know if the ADC impedance in stm32f1xx devices matches my sensor impedance or not?MCU Lüfter
Posted on November 11, 2012 at 23:46Reading UM0033, page 138, figure 14. Sorry, can not exactly understand it. For example, I want to connect C.8 to CAN1_TX and C.9 to CAN1_RX. I see AF9 (CAN1/CAN2, TIM12..14). and need to use GPIOC_AFRH(LSB) GPIO...
Posted on November 10, 2012 at 15:32Hi, I have always programmed in C + + and Java or C ♯ and now that I start using microcontrollers have a lot of trouble! can you recommend a good Book of C or a good online guide? thanks #learning-c
