Enabling Interrupt for UART stops HAL_Delay

Hi everyone,I'm new to the ST world so I apologise if I am asking a simple question.I have a NUCLEO-L4R5ZI-P, I made a new project and cleared the pin outs and started fresh.I have enabled USART2 and can send and receive data in polling mode.If I go ...

How do I maximize baudrate via USART with STM32L4P?

Hi STM32-Community,I'm currently trying to maximize my dataouput. I've about 150 KB/s data, which are sent out via RS485 and connected with a RS485 to USB to my PC. The USART Clock is at 64 MHz, though 80 MHz viable aswell, which means I should be ab...

STM32U5 Cannot enable ADC (timeout on polling for ADC_ISR:ASRDY)

I'm using CubeIDE 1.7.0 and a Nucleo board to initialize and start ADC1 (at default settings, more or less).The issue is that HAL_ADC_Start() would return HAL_ERROR due to a timeout. This is probably Clock-related but I couldn't figure it out yet.Her...

How do I configure PVD on STM32L081KZT?

Hello STM Community! This is my first Question in this Forum.I am using a STM32L081KZT and I need to save data, when the Power is unplugged. My setup is powered by USART and can only be turned off by unplugging the UART cable. In that case I need to ...

How to use HAL_StatusTypeDef HAL_CRYP_Init(CRYP_HandleTypeDef *hcryp) correctly if I want to change OperationMode in hcryp manually in-code?

Currently using the built in functions generated for AES Hardware acceleration and was wondering how to use HAL_StatusTypeDef HAL_CRYP_Init(CRYP_HandleTypeDef *hcryp) correctly if I want to change OperationMode in hcryp manually in-code? (from what I...

defined things called "undeclared"

Hi, my processor is STM32L010C6TX. I added function to my project to use microsecond But " DWT" "CTRL" etc. It says not defined. However, they are all in the "core_cm4.h" library. This library is in Drivers-> CMSIS->Include. why doesn't it call this ...

8 timers of 2 Stm32f7 Synchronization

Hello everyone,I have used 2 Stm32f7 nucleo boards to read the data of 8 incremental encoders. for this purpose, I have used timers. I can read the data of encoders correctly but there is a little bit time difference between timers. it means I need t...

Hello everyone, I'm new to STM and I would like to know if it is possible, to draw rectangles on PC Window like a rectangle or cricle on the symbols or anything. Are there some libraries to draw stuff on PC Window?

STM32H747I LQFP176 Package Pin-out mistake in datasheet

The LQFP176 Pin-out at Page no.76 of STM32H747I in datasheet (DS12930 Rev 1) has a mistake at pins 158 & 159.Pin 158 has been mentioned as VSS instead of PG14.Pin 159 has been mentioned as PG14 instead of VSS.But at Page no.86 these 2 pin functions a...
