I got some excellent advice on a previous question and have a new related question. I have a app that needs to run a control loop at a specific rate with something like a few percent jitter. For example, if the control loop is supposed to run every...
Hello, I am beginner and I am trying to write a code without HALL. The goal is switch LED when button press using interrupts. I check the button and the LED separately. Everything works fine. But interrupt code don't want to. What am I doing wrong? U...
It seems to me that st-flash still have not got any support for STM32H7xx devices yetIs there other command line options available that run under Ubuntu? Could be payware even.. I have both stlink/v2 and a segger j-link (EDU version) available but ha...
In order to create a faster scrollbar function I need to fill a bitmap structure with an area get from the screen.I have starting to develop this new function starting from the BSP_LCD_DrawBitmap source but how to reverse the LL_ConvertLineToARGB8888...
I am using a self compiled arm-none-eabi gcc 10.2 toolchain and I am trying to write a minimal program to switch on a GPIO LED (putting that output to 0 because is cathode connected) on pin PA1. I have the following resulting binary:Disassembly of se...
Hi,I want to use the VEREFINT to get the voltage of my battery. According to the formula provided by the datasheet (screenshot attached), I need the VREFINT calibration value and the VREFINT_DATA.What is the register to read the calibration value fr...
Hello,I am working with the evaluation board STM32L412 Nucluo64, but I noticed that the MCU sends only garbage from UART.The code I am using has been used many times in other projects and should work fine (it's just a matter of calling LL_UART_Transm...
Hello,I'm encouring one problem with STM32F405 interrupts.I'm working on a project that using a MCU STM32F405,I have created a CubeMx Projet, set all the clock (input frequency, Sysclck, APB1, ...), set timer2, CAN2 and UART2. I have set enable TIM2 ...
I am trrying to send messages via the second fdcan in classic can format. I am watching the bus with CANoe, but only FDCAN1 (classic master) seems to be able to transmit. If I try to transmit with FDCAN2 (classic slave) my buffer fills up but nothing...
Hello.I am looking for example of External Qspi Loader for the Stm32h743.I manage to make my functions work. but not to create the .stldrI have the impression that he does not take Init.I am under Stm32cubeide.thank you
