Posted on December 22, 2011 at 14:04Hello, I'm truing to use STM32F217 and CS4344 for my audio application. I have problem with clock initialization. /* Enable HSE */ RCC->CR |= ((uint32_t)RCC_CR_HSEON); /* Wait till HSE is ready and if Time o...
Posted on December 20, 2011 at 10:52 Hello, I can synthesize a waveform into a buffer, dma transfering it to dac. Result is ok but there's a noise that I can't remove. When the waveform is a 0 signal, the noise is still here. The n...
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...
