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...

Android USB HID driver for STM32F1 Series

Hello there.  I am trying to implement a USB HID driver for the STM32F1 series.  I tried several generic examples of Android USB HID drivers on the web, but none of them seem to work with what we have.  I was wondering, how would I approach implement...

How to debug properly UART interrupts?

My UART works well in normal mode, but when I want to analyze callbacks for Rx in debug mode it doesn't work properly. I mean when I set breakpoint at HAL_UART_RxCpltCallback and I'will send bytes from terminal, debugger stops at this callback and do...
