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...
Is it possible to use the ADC peripheral of STM32H723 in dual regular simultaneous mode (ADC1+ADC2) with oversampling?
I am working with an STM32U585 microcontroller, and I need to perform read, write, and erase operations on the internal flash memory (Bank 1) with TrustZone security enabled. The page size is 8 KB, and I am encountering an issue when trying to write ...
Hi,In STM32U5, the GPDMA has both request sources and trigger sources, what's the difference between them?Thanks.
Hi,MCU -stm32h743I have noticed that some RAMECC1 registers have a non-zero value on reset which is against the information given in the datasheet. For example, see the snapshot below:This is when the control is at the starting of main(). As per tabl...
MCU: STM32H753VI Scenario:I am working on the error management system for our firmware. Part of that is handling ECC errors in flash and RAM. I have been able to successfully inject and handle flash ECC errors, but am having trouble with RAM ECC. Pro...
