will B-L475E-IOT01A board supports FFT commands like converting time dominie to frequency dominie.
I am trying to convert time dominie to frequency dominie to calculate FFT of that data. If so, who can I do that.

STM32L4P5CET ADC freezes at high noise environment
I'm using an STM32L4 for a solar inverter control project to control some H-bridges and sense some voltage and current. I run into this particular issue that when the environment is noisy (the DC input to the H-bridge is high), the ADC sometimes will...
Wrong SVD file for STM32G491 device
TIM20 peripheral is missing in the SVD file for STM32G491 deployed in Keil PACK STM32G4xx_FDP v1.4.0Please see the attached fix with all files rebuilt (SFR and SFD)
[STM32L433] Asking if there is an example code about how to enter/exit low power sleep mode correctly.
Hi everyone,I'm working on STM32L433 Nucleo-64 board and I would like to try the low power sleep mode to see the power consumption part.From datasheet, current consumption us XXuA. Use my example code, the current consumption(PIN is JP6) is about 5....
Problem with USART Communication during updates
I am using an STM32L4 chip that sends an update to the nRF52832 on a ublox module over USART. I assume the nordic chip is in the bootloader during the update.We get a UART error: 4 and when we observe the UART lines we see that on the TX line of the...
What is the relation between ADON(ADC_CR2) and SWSTART with Sample and Hold schematic. STM32F415 device.
I have to replace HAL(ADC) with self made implementation (regular channel, 1 channel, single conversion).During that, i found that delay between setting of ADON and SWSTART (Tstab) is significant for the quality of the measurement (stm32f4xx_hal_adc....
STM32H743: BDMA channel for SAI interface does not work.
I would like to use SAI interface, but the initial setup seems to be failing. ErrorHandler was called because of FIFO is Empty after calling HAL_SAI_Transmit_DMA().The SAI is set up as follows: hsai_BlockA4.Instance = SAI4_Block_A; hsai_BlockA4.I...
Why I can not call function from address 0x00000000 or 0x08000000?
I have created a pointer to function like void (*MyFun)(void); and I assigned first time 0x00000000 and the second time 0x08000000. in both cases after call MyFun(); I get HardFault error.Why? PS. This is simple project created in CubeIDE (default pr...
Interupt driven uart reception not working
Hi all iam working in stm32 f051c8tx microcontroller im trying to recieve a byte and if i recieve a byte in intrupt im printing "hello world " via tx of the same uart, the issue is im not able to recieve any char the below is the code any thoughts p...
