STM32F37, SDADC stops working when USB connected/disconnected
Posted on September 18, 2013 at 12:55We have an STM32F37 running the SDADC perfectly. It also communicates via USB perfectly. Unfortunatly the SDADC stops working (gives reading of 0) when USB plug is pulled out. Also the SDADC stops working when US...
Pin Compatibility between STM32 family ?
Posted on September 15, 2013 at 15:17Guys, Does STM32F103XX series have a pin compatibility with STM32F105xx, 107xx and 207xx ? Any ideas will be appreciated, Thanks
Any iDea on using Circular Buffer for DSP application
Posted on October 06, 2013 at 19:11Hi,I want to know about the use of circular buffer so that I can efficiently utilize the cycles available to me every Sampling Interval, to make a low pass filter of order 3.Best Regards,Umair Mukati. #dsp-dma #...
Accuracy of factory programmed VREFINT_Factory_CONV
Posted on October 09, 2013 at 15:43Hi, I'm using the STM32L151 for a project which needs some reasonably precise (~0.1%) voltage measurements. I'm measuring the micro's 3V3 supply by converting the internal reference and using the factory programme...
STM32F10xxx DSP library FFT algorithm
Posted on October 11, 2011 at 12:34Hi, I am using STM32F10xxx DSP library (not the CMSIS DSP)algorithm for calculating FFT of an input sequence. I want to know the order in whcih the input samples is expected by this algorithm and the order in which...
Systick default clock setting for stm32f3discovery_fw

3 PWM channels with different dead time
Posted on October 09, 2013 at 11:58Hello, I am working with the PWM peripheral of the STM32.My problem is to get 3 complementary PWM signals with different dead time. Does any one has an idea to do this? Thank you.
Bypass capacitors for STM32F0 series?
Posted on October 09, 2013 at 10:43Hi.I am designing a test board using STM32F0 series MCU.On the datasheet, it states I have to attach 3 bypass capacitors(2 x 0.1uF, 1 x 4.7 uF) per each VDD. Is it absolutely necessary?, What is the point of using...
