Real Time Data Acquisition from STM32f407 to MATLAB

I am getting data from a current sensor through the adc of stm32f407. I want to export that data to MATLAB at real time or at least at sampling frequency of 10 kHz. I tried STM Studio but its sampling rate is only 1 kHz. So please let me know what sh...

To wich parameter refers HSE oscillator characteristic Gm in STM32L443 datasheet on page 123? Does it refer to AN2867 parameter gm or to Gm_crit_max?

I'm in doubt about the transconductance parameter of the HSE oscillator in STM32L443.To select an appropriate cristal I studied AN2867.If the datasheet of STM32L443 which notes "Gm = 1.5mA/V" refers to gm the transconductance of the passive elements ...

Resolved! HSE fails to initialize in STM32F205ZG using SPL

hello!  I was devolving my project on the "STM3220xG eval-board" (based on controller "STM32F207IGH6"). Now as my custom made controller board is ready (based on "STM32F205ZGT6"), I ported my code for it by changing in peripheral's Pin-numbers and Ke...
