Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
Dear STM32 Community,I am currently working on a project using STM32CubeIDE, and I need to perform calculations that involve floating-point numbers. Specifically, I would like to extract exactly two decimal places from a float number without roundin...
Hello everyone, I'm encountering a problem with the development of my timer on a STM32G474VE. I have to use the TIM2 in encoder mode + index. I'm using a custom board. I started with a cubeMX project, initialising the timer in encoder + index mode. ...
So my stm32h7 works fine using regular interrupts. But when doing it via DMA, void HAL_ADC_ConvCpltCallback(ADC_HandleTypeDef *adc)is never called.I enabled ADC global interrupt and BDMA channel0 global interrupt.circular buffer,continuous conversion...
I have a TFT display which outputs 320 X 240 pixels and I want to control the display brightness from the command itself which I found in the datasheet of the TFT display controller IC, so with the reference from the datasheet I have to trigger the W...
Hi,I have a custom loader and am using STMCube32 IDE and QSPI. I have the linker etc all setup such that my assets (.c files of the BMPs) is loaded into QSPI and used by LVGL.My question is - given loading via the STLink 5MB of images takes ~2 mins e...
Hello,I've been trying to make USBx (device_only mode) MSC work on my NUCLEO-U5A5ZJ-Q for 2 weeks now, and I don't know what I'm doing wrong.I've tried to run the tinyUSB MSC example and it works fine so the hardware is ok.When using USBx, after some...
I am using a custom board based on the STM32H750VBT6. I have set up the board as a USB FS device and added some test code to blink and LED based on the serial data sent over USB. I have gotten it to function properly on my Ubuntu machine, however, wh...
Hello everyone I want to interface ads115 Adc with stm32f446re nucleo. All the necessary connection between ads1115 and stm32 are made with I2c Can I get the example source code to read multiple channels.As I am not able to get values from adcIs any...
Hi all,I spent hours but I cannot make UART work in DMA circular mode with RTOS (CMSIS V2).Can someone send me a simple example ?I would like to receive characters from PC (various length commands: 8-10 chars) and process them in another task paralle...
Hello I am developing on the NUCLEO-H563ZI board a system in which I need to obtain an IP address via DHCP.I have implemented the client following the guidelines of the documentation provided by ST as well as THREADX and NETXDUO and, I have strange b...
