Do not erase a sector on subsequent SW uploads
Hello, I'm using a STM32F103 and my code needs to save a few parameters from calibration activities in factory in the FLASH. I have successfully configured the last sector and I use it.Then, what I'd like is:FLASH the STM32 with the whole SW the 1st ...
Resolved! Question regarding FFTs in arm_math.h
Hello! I am trying to simulate an octave model on a microcontroller and ran into a snag I thought I'd get some help with. So I have an FFT I am running on a sample of data (we'll say 4096 bytes). In octave, I'm using an FFT of the sample (where the s...
Boot0 pin on STM32L011 has internal pull resistor?
Hello all.I'm using BOOT0-PB9 pin on a STM32L011. In the reference manual I've found that "The pin logic level can then be read as an input value on the shared GPIO pin.", but nothing about internal pull resistor.The question is: is this pin provided...
hi iam trying to find FFT using stm32F4 discovery board. i have tried using CFFT and RFFT available in arm CMSIS DSP library but iam getting wrong answers. Can someone please tell me where iam wrong. Iam posting the code below for both RFFT and CFFT ?

Resolved! UART RECEIVE PROBLEM / STM32G061C6
Hi all,I am using a STM32G061C6T6 MCU. I'm trying to contact Nextion HMI. My data sending is successful, but I can't get any data. I couldn't run any of the Pooling and interrupt methods when receiving data. When I follow the RX pin with the oscillos...
Communication via RS485 stop working after random time
Hi everybody,This is the first time I'm writing in a forum so I'm sorry if I didn't right.I'm developed a board based on STM32F091VBT.I'm using this board to communicate with other devices (two touch, a gateway and another board based on STM32F091VBT...
RTC clocks problem
Something is wrong with the clocking and i cant figure out. When i try to debug with step over, the error handler in void SystemClock_Config(void) if (HAL_RCC_OscConfig(&RCC_OscInitStruct) != HAL_OK) { Error_Handler(); }Takes me to /* Wait till L...
Resolved! I want the code is copied from Flash to RAM after poweron,then the code is running at RAM.
I've changed the .ld file for STM32G474 generated by STM32CUBEIDE.The part of old .ld file is like this,I added ">RAM AT" at the last line like this,But when I'm debugging,the code is running into the HardFault Handler.I want to know if something els...
