HAL_I2C_GetError() reporting error codes

Hello, We have noticed communication errors with STM32 that is working in our device. The device includes STM32 (master) and TI's battery monitor BQ76952 (slave).Using the same device and same software we noticed three situations that occur randomly:...

Is this a HAL IIC bug?

Hi there,I drove 4 SHT4x by STM32G473VE and used the HAL_I2C_Master_Transmit() and HAL_I2C_Master_Receive() to write and read the sensors.Normally, everything is well.However, if Iunplug the sensor;replug the sensor again;(Not the sensor maybe can NO...

OpenOCD does not bypass data cache

I'm using STM32H7S78-DK and STM32CubeIDE v1.17.0. I was try to get Segger RTT working so I switched from ST-Link GDB server to OpenOCD because it has in-built RTT telnet server, but couldn't because OpenOCD didn't find RTT area.I reduced the problem ...

Does STM32U585 support USB Device Library for baremetal? Or is there only a library for ThreadX? If such - do ST plans implement a USB Device library (Middleware) for bare metal applications?

Custom external RTC DS3231 implementation in LoRaWan Wio E5 project

I am using Seeed Studio LoRaWan Project for Wio E5 Mini(STM32WLE5JC6). By default the project is using internal RTC, but I want to use an external RTC DS3231 alarm for my application to send data because it would be run through the power line and whe...
