Posted on December 23, 2011 at 12:09Hello, i am programming the bootloader for the stm32f103c8 mcu. The SW has bootloader part and application part. In the application I use the function NVIC_GenerateSystemReset() to reset the mcu to the bootloade...
Posted on December 20, 2011 at 14:26Hi every stm32 fan, In my application I am sampling my input signal at 8KHz and now I need to filter out my samples in order to remove high components. Is there a software tool which computes the coefficients of a...
Posted on December 22, 2011 at 23:09I have built a baseboard for the STM32F4 Discovery module. It has two RS232 ports and two 50-pin headers allow easier connection to the other pins. I have some photos on my blog:http://kornakprotoblog.blogspot.co...
Posted on December 21, 2011 at 17:29(I moved my question to here from STM32F4-DISCOVERY. Thought this would be the proper place to ask for help). I am using TIM2_CH3 configured for a DMA1 request on Stream1_Channel3. On Output Compare I would like T...
Posted on December 21, 2011 at 18:54Hi We have an odd problem. We have a custom F205RBT6 based board. It can be powered through separate 5V pins or USB. The 5V goes to a 800mA linear regulator which then provides 3.3V to the F205. We have an extra l...

Posted on December 21, 2011 at 12:45How can I synchronize the timer output with a maximum frequency PLL, ie 168 MHz. In my example I set the timer to slow generate an interrupt, which run fast timer for generating a single pulse duration of 6 ns, b...
Posted on December 21, 2011 at 15:59I had a few general questions regarding the RTX RTOS on an STM32F4. What are the limitations with regard to the FPU while using RTX? Is it possible to switch tasks while in the middle of a floating point operati...
