STM32 MCUs Products

I am new to STM32. I and trying to learn STM32G0. Which tool I should use from the following. In future I will also be using STM32F769 also. I want to use only Free Tools. 1. SW4STM32 2. TrueStudio 3. STM32CubeIDE

STM32F7 and MPU

Hello everyone,I apply STM32F746BE with externel SDRAM 32MB (MT48LC16M16A2P-75 IT:D) and externel FLASH 16MB (MX25L12845GM2I-10G), Ethernet (LAN8710AI-EZK), LCD.Vector' table is located at 0x20000000. Firmware is runned from externel FLASH 0x90000000...

Time consumption FFT calculation. CMSIS, STM32F401RE

Hello,i calculate an FFT with the STM32F401RE. It works fine so far. Here are the relevant code snippets:arm_rfft_q31(&S1, (q31_t*)fft_input_buf1, (q31_t*)fft_complex_buf1); //takes about 1760 µs   arm_cmplx_mag_q31((q31_t*)fft_complex_buf1, (q31_t*...

Can't set Option Byte with the attached function for the Micro STM32L151CBT6A Only when the controller is new from factory. If we erase and reset the option bytes the STM32 afterwards new flashing it works.

Application Interrupt and Reset Control Register behaviour

I'm using a STM32F401RE.I'm trying to perform a Reset using the Application Interrupt and Reset Control Registerhttps://developer.arm.com/documentation/dui0497/a/cortex-m0-peripherals/system-control-block/application-interrupt-and-reset-control-regis...

Dear Sir or Madame, We are currently developing an application where the current consumption is very limited. We are using a "STM32L4S5VIT" Especially at the beginning( Boot process) the current consumption is very high.

What are the possibilities t reduce the current cosumption at the beginning. Can you give me some information about basic mechanisms to throttle the required power especially in the boot process. Is there a documentation available regarding to this ...

Stuck at faults in CPU registers

Hi,Can somebody help me to understand the below thing?How to detect CPU registers stuck at faults? If CPU registers are stuck at fault, How can instruction send/stored in that register will be the actual one? I mean to test CPU register stuck at faul...
