Posted on June 18, 2014 at 21:48Hey, I am looking for some working examples for the STM32F407 for the Ethernet, SPI, I2C, and USART. I have been using an STM32F4 Discovery board and an STM32F4 ETH Mountaineer board to evaluate the uP. But I have not...
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_...
Posted on June 18, 2014 at 12:54Hi,I am novice in MCU. I am wondering can I use the USB and SDIO on STM32F4 without external crystal? Will the internal oscillator be sufficient?Thanks.
