Posted on June 17, 2014 at 19:20Hi there, I'd like to build a USB Audio Class device that can synchronize to the 1kHz SOF so that samples are never lost or added due to clock frequency differences between the host crystal and the sample rate oscil...
Posted on June 19, 2014 at 01:52My EWARM assembler code allocates .noinit data via DC32 in the CCM for the STM32F4 Discovery Board. That data is initialized by my code and only allocated so the labels acn be linked in the assembly code. Using the ST...
Posted on June 18, 2014 at 21:18I copy 2 projects into mine, one is PWM, the other one is Examples\ADC\ADC_RegularConversion_DMA. Both of them work perfectly separatelybefore, but after copied, only one can work.Iguess it might because some functi...
Posted on May 21, 2014 at 12:25I read the unique ID of STM32F407 microcontroller but i want to know what this unique ID represents means is there these bits can show any format or fields???Is this ID represents the features of microcontroller if yes...
Posted on June 16, 2014 at 10:48hi,allI'm now working on a project using stm32f103.And I need to build up an environment for unit testing, regression testing and code coverage testing .Any tools or solution?Many thanks. #stm32-regression-test

Posted on June 15, 2014 at 13:45Hi, I am trying to control a TFT over LVDS with an STM32F429. At around 30 MHz the Signal seems to be ok, but the Display wants at least 40MHz. Turning up the Speed above ~33Mhz is messing up the clock signal and visi...

Posted on June 16, 2014 at 16:22Hi, I have STM32L1 work with STM32 VCP library The VCP work very well in windows, but I need work in the linux embedded with kernel 3.11I tried but linux does not detect the STM32 VCP, while the FTDI work very well in...
Posted on June 18, 2014 at 12:54Hello, i'v try to compile example fft code using stm dsp libraries. Got this error message: /usr/gcc-arm-none-eabi-4_7-2013q1/bin/../lib/gcc/arm-none-eabi/4.7.3/../../../../arm-none-eabi/lib/armv7e-m/fpu/libm.a(lib_...
