Posted on February 26, 2013 at 21:26Hello!Use stm32f107vc.I'm trying to synchronize two timers (TIM3 and TIM5), as including the external trigger. Configure them, as described in RM0008 page 386:void TIM3(void){RCC->APB1ENR |= RCC_APB1ENR_TIM3EN;TIM...
Posted on March 01, 2013 at 04:44Dear, I want to test the systick clock frequency. And use the systick as the RTOS system timer. It would be set to 1ms. And I use the configuration of the demo code as following: if (SysTick_Config(SystemCoreClo...
Posted on March 05, 2013 at 00:05Per the datasheet,Random number generatorThermal noise in the analog circuitry is digitized to provide entropy for a true randomnumber generator (TRNG). The TRNG produces 16-bit uniformly distributed numbers. TheSoft...
Posted on March 04, 2013 at 21:06Hi all, I'm using an STM32F4Discovery (it's and STM32F407VGT6 on it).I'm trying to use the TIM4 timer to read a quadratic encoder (plugged on PB6-PB7), but somehow, it doesn't work.I'm using exactly the same code wit...
Posted on March 01, 2013 at 22:32I would like to do a background CRC32 on FLASH such that I do 256 bytes at a time and get a final result. The system must continue to run and meet RT deadlines while the CRC is calculated. Additionally, communicati...
Posted on March 04, 2013 at 21:52Hi,I am having trouble combining the demonstration project with the USB virtual com port loop project in Atollic TrueStudio(based on eclipse). In order to simplify things, I first basically tried to run the USB virtu...

Posted on March 04, 2013 at 03:51It is possible to have two serial outputs under master mode for one SPI? I need to drive two groups of devices at the same time with DIFFERENT data on ONE clock signal. That is, I need and only need one clock signal,...
Posted on March 04, 2013 at 11:15Hello, I am beginner with STM32. I have STM32F3 and I use DAC. I need to know value of Vref+, but I can´t find this number in datasheet, ref.manual or pin Vref+ on discovery kit. Do you know where can I find this nu...
Posted on February 28, 2013 at 16:54 I have to receive a data on my stm32f100 microcontroller which is sent from a software on PC through RS232 port. I am using IAR C compiler and in the interrupt handler i have some further sensor related progr...
