Posted on September 12, 2017 at 12:59Dear Community,I noticed a strange problem while attempting to program a STM32F051 device. The device is part of a larger circuit and gets its supply voltage from a 3.3V LDO regulator and the VDDA is supplied by ...

Posted on June 08, 2017 at 15:04Dear Community,I want to send and receive SPI data using the SPI-Irq handler of a STM32F407 device. Using a low speed SPI everything worked so far but now I need to speed thinks up and I noticed that receiving works m...

Posted on May 09, 2017 at 09:12Dear Community,I want to implement a boot loader routine located in the first flash sector (0x8000000) of a stm32F407 device. After power up the bootloader decides whether the program pointer can jump to the main app l...

Posted on April 20, 2017 at 10:55Dear Community,I want to use the arm package: arm_cfft_radix4 to perform a 1K FFT repetitively in a loop on a STM32F407 device. To do so I predefined: __FPU_PRESENT=1,ARM_MATH_CM4 and added the library arm_cortexM4lf...

Posted on April 13, 2017 at 09:10Dear Community,to realize a nearly ideal low pass (without phase shift) – filter I need to perform a symmetric running average operation using the STM32F4 core. This operation takes 3000 sampled points of raw data an...
