You want to use TIM1 to trigger GPDMA to move the GPIOB->IDR data to a variable. The previous implementations were based on stm32L4, but I don't know how to implement gpdma. Attached L4 project. *This post has been translated from Chinese to comply...
HiI don't know how to configure the CAN filter bank registers to receive extended IDs in ID list mode.Naturally, I read the manual, but there was no explanation.Even if there was, it would probably be difficult to understand. I found the following d...
Hey St Forum, Just getting a new project off the ground, and working with the STM32H7S7 Dev Kit. So far, I've been able to get some example code up loaded into CubeIDE, and upload to the board. However, when I try and debug, I get this error: Viewing...
Hi, I try to use arm_fir_f32 from CMSIS-DSP to bandpass my signal. But the program always run into the hard fault handler.I wonder if that could be i didn't correctly import the CMSIS-DSP library. I followed the instruction from https://community.st....
Hi I am working on an embedded project with the STM32C031C6 microcontroller using STM32CubeIDE. My goal is to perform an FFT on ADC input data and transmit the results over UART. I am utilizing the ARM CMSIS-DSP library for the FFT processing.Here ar...
On an STM32F103CB, running as a Custom USB HID FS device, I have this USB HID Report Descriptor (I'm only showing Report ID 2): 0x06,0x70,0xff, // Usage Page: Vendor defined 0x09,0x06, // Usage 0xa1,0x01, // Collection: Applica...
Hi everyone, I'm a student who was assigned to make an ESP32 NodeMCU WiFi CP2102communicate with the magnificent STM32h755zqi board via usart, simply I wanted to start by writing a simplesentence on the terminal (I know how to use putty) to actually ...
This code, partially generated by Copilot, does only print "="At the same time, I do see that the device PB6(SCL) and PB7(SDA) recieves packets adressed to it, requestng data. #include <Arduino.h> #define I2C_ADDRESS 0x0B volatile int x = 0; volati...
Hi,I have a question about whether or not the USB VBUS connection needs to be made to the micro on the STM32H series micros (in particular the STM32H725) when operating the USB in device mode.We are using a USB-C type connection, so we have an indepe...
Hello;I'm writing a driver for a tlv493d magnetic encoder using CubeIDE. This encoder has a peculiarity where it pulls the SCL line of an i2c bus low when it has data ready to be read, at which point the MCU needs to initiate an i2c receive transacti...
