I have a custom build setup in VSCode, where I'm using CMake with Ninja to generate build files while using a GCC 12.3 delivered with STM32CubeIDE and GDB as well. For the hardware part I have a standalone STM32U535 MCU with SWD connection and ST-LIN...

I'm unsure whether this is a software issue or wake-up callback is by default not present for UART on STM32U535 microcontroller. The rest of callbacks seems to be in place.

Simple question, I'm trying to locate a user manual for STM32U5xx HAL library but can't find it. The official STM32U5 ST page doesn't provide it. And neither does the STM32CubeU5. Does this mean it doesn't exit yet? But if code is there, then it shou...

I'm using HAL UART Receive with DMA (configured using CubeMX). I'm encountering a problem where data via UART, send in chunks, is corrupted if a chunk doesn't fit at the end of buffer perfectly. By chunks I mean a set of byte-sized data that is trans...

I'm trying to calculate the period of DMA ADC interrupt triggered when the destination buffer is completely full. As of my understanding the period is:T_dmaDone = [(T_sample + T_conv) * sampleCount * channelCount] / F_adcIn my case each rank is set t...

I was able to solve this issue by figuring out I was still using "TransferComplete()" UART IT callback which contained code from previous UART reception setup that used IT only without DMA. After releasing that callback DMA writes during wrap-around ...

No, not always. As mentioned above I'm using DMA with UART to effectively catch all the bytes arriving from serial terminal. Most of the time received chars are 1-byte per key press. However, sometimes when pressing special function keys (e.g. F1 key...

The HAL implementation here is honestly a mess, can be done much more simply.Unless HAL configures DMA in some inappropriate manner I don't think HAL is to be blamed in this case. As you see from my question I'm only using CNDTR register to check spe...

I'll see what I can do but that's really pretty much it as far the DMA and UART is concerned. Before DMA I was trying out a setup with UART IT, however at certain UART baud rate sometimes bytes were not caught at proper times by the software. Also, i...

I wouldn't call this documentation error since HAL docs always provide explanation over returned status as "HAL Status". Maybe inconsistency between different but somewhat similar HAL libraries like serial protocols.Kudos for pointing out that intern...
