Posted on January 03, 2014 at 22:45I have been unable to determine from the datasheets or application notes what the real behavior of the ADC in the STM32F303 is when in differential mode. This leads to two questions: 1) Can V_neg be greater than V...
Posted on September 24, 2010 at 01:00 STM USB Library Bug? Gets stuck in interrupt
Posted on January 06, 2014 at 13:26Dear sirs, we use the ADC in continous scan mode. The results are written per DMA. Our application has to perform a ramtest. For this test we need to stop the DMA every ten minutes for about one millisecond and re...
Posted on January 05, 2014 at 08:17I am trying to attach interrupt to my motor encoder ( connected to pin PB9). My idea is to get the pulse count as the motor rotates. Shown below is a snippet of my code to attach interrupt to pin PB9. I should be g...
Posted on January 06, 2014 at 13:13Hi,I would need 3 USARTs for a project (I am using stm32f103vct6 microcontroller). One USART is already functional properly which is USART1. I am trying same with USART2. Transmit is working fine but but RXNE flag ...
Posted on December 19, 2013 at 15:46 I have this code that is trying to put my HSE clock onto MCO1 (A8) on my STM32F407 Discovery, but it doesn't work. Anyone know what's wrong? #include ''stm32f4xx_gpio.h'' #include ''stm32f4xx_rcc.h...

Posted on December 23, 2013 at 10:51Hello together,I try to get to work the STM32F4-Discovery-Board with the LCD-Display. I have the code of the graphic-workshop from ST. In this code the STemWin-Library of segger is used without the source code, on...
Posted on January 06, 2014 at 06:32Guys, How can I add a new task on FreeRTOS on STM32 ? I have created : [CODE] #define LCD_TASK_STACK_SIZE ( configMINIMAL_STACK_SIZE ) #define LCD_TASK_PRIORITY ( tskIDLE_PRIORITY + 1 ) #defin...
Posted on January 06, 2014 at 02:10Hi,I am working on a couple of projects that incorporate USB Mass Storage, i am using an STM32F103RB MCU and the micro SD card is connected via SPI.The maximum transfer rate i am getting is around 85 kB/sec.I am tr...
