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...
