Posted on October 01, 2013 at 21:43I am using STM32F103R6 for a motor control application.STM states that the APB 1 frequency limit is 36 MHz, but I am using it with 72MHz and it looks like that all peripherals work fine. What risk am I taking? Is t...
Posted on October 09, 2013 at 10:19Dear All, If I use the FMC external bus to drive SDRAM and also some NOR flash and a display via an SSD1963, do you recommend buffering the bus between the SDRAM and the Flash / Display? I've looked at various app...

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...
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
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 #...
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...
Posted on October 11, 2011 at 12:34 Hi,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 which the input samples is expected by this algorithm and the order in which...
Posted on October 08, 2013 at 10:42Hi all,I�m starting to deal with STM32F30 discovery.I need confirmation about my assertion on default clock configuration for the stm32f3discovery_fw.In file system_stm32f30x.c the define PLL_SOURCE_HSE_BYPASS is u...
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...
