how to generate random time series signal in stm32 and perform fft and compare its results

timer

I am using NUCLEO-H743ZI2. I am trying timer to generate pulse using TIM_OCMODE_TOGGLE channel 1. my timer clock is 100MHz, I set pre-scaler as 9 and channel 1 pulse as 9 as well. It seems it is difficult to get pulse, except I add more count on chan...

How do I prevent one ISR from interrupting another ISR that is in the process of reading the RTC? HAL_LOCK?

I'm working on my first large-ish C++ embedded program running on a STM32F413. Bare metal, no RTOS at least so far. The program reads data from a dozen or so UART and I2C sensors. All the UART sensors currently use DMA for TX and RX. When a compl...

Cable length limitation for SPI run at 40MHz ???

I had trouble to activate SPI communication with SPI in 40MHz frequency in 55cm long cable , even I modified output speed to "Very high speed" . Is any other register that I need to set to support high speed clock in long length cable ? 55cm long cab...

SPIN3204 example code (STSW-SPIN3204-V1.0.0) project compiler issue

We have download the SPIN3204 FW (STSW-SPIN3204-V1.0.0) from ST website.But the Project_Potentiometer.uvprojx compiler error on keil SDK.​Is there a way for me to run this project normally?

STM32G071 running "ADC_SingleConversion_TriggerTimer_DMA" The application is not setup to trigger a conversion on the timer.

Also, TIM15 seems to be documented as having CR2 MMS -- but does it? IAR does not think so.

Why contains STM32F1_Med_density_LQFP48.bsd pin numbers above 48?

Hello.I think version 2.0 of STM32F1_Med_density_LQFP48.bsd is wrong, since it contains pins above 48 (e.g. BOOT0: 60, JTDI: 50). On further inspection, its contents are equal to STM32F1_Med_density_LQFP64.bsd.Unfortunately, STM32F1_Low_Med_density_v...

Several question regarding STM32Fx (TIMx,DMA,ADC)

Hello,I have few questions regarding the TIMER capabilities confgured as input capture. According to the reference manual, the direct input capture of TIMxCH1 in conjunction with a TMxCH2 which is configured as "indirect input capture mode" along ...

Use STM32H743II with an external ldo for vcore @ 400MHz

We would use a STM32H743II with an external ldo for vcore. In the datasheet are tables (page 114, table 31) with regulator on but no tables with regulator off.In the datasheet at page 114 is a table (table 31) for maximum current vs. junction tempera...
