STEVAL PROTEUS-1 - Modal analysis using impact hammer
Dear all, I'm trying to evaluate the IIS3DWB sensor using the STEVAL PROTEUS-1. Would it be possible to use the sensor to capture transient vibration e.g. Modal test using an impact hammer? Is there an example script for STEVAL PROTEUS-1, to capture ...
Resolved! Cannot receive full string on UART Receive -ST32H745 Disco Board
I am sending a string "Chicken" word on UART Transmit and I want to check if I can receive the full string in the UART receive. To do that, I have physically connected the TX and RX pin together via a wire.I am able to check that Transmit is working ...
STM32F030CC Bootloader application stuck at first HAL_Delay
Hi, I am working on STM32F030CC microcontroller, where I am calling an application code from bootloader code. When the code is entering the application, the program is entering into an infinite loop of HAL_Delay(). I found out that by adding "SCB->VT...
Resolved! What is the required timing between ADC initialization and calibration on the STM32G0B1?
We are using the STM32G0B1CC and have noticed that if we call HAL_ADCEx_Calibration_Start() too soon after calling HAL_ADC_Init() that the CALFACT register comes back as 0. If we insert a substantial delay, say 20 ms between the 2 calls, CALFACT is p...
SRC236/441 libs with Hard FPU support?
I believe all of the audio processing addon libs, (SRC236/SRC441) are built without hardware FPU support. The problem is my entire project was built with hard FPU support. I tried the mixed SW/HW, but that didn't solve the issue and I couldn't build ...
Communication with STEVAL-MKI109V3 kit
I would like to use STEVAL-MKI109V3 with LSM6DSV16x Imu sensor. I have other tools like ESP32 and some sensors that controls autobrake system based on IMU data. I communicate between ESP32 and PC(Python) through BLE. However, if I add STM32F401VE. th...

Resolved! (SOLVED) STM32H743ZIT6: Bad accuracy of TIM2 (32Bit Timer)
Hello,I am having accuracy issues on TIM2 (32Bit Timer). I am feeding the PLL with an HSE 32MHz crystal (which seems to be fine when I measure the MCO frequency). I have setup the Prescalers to reach a frequency of 240MHz for the APB1 Timer clocks (w...
