ADC + DMA convCplt and convHalfCplt

Hi,I am trying to use a circular DMA to transfer ADC samples on STM32L4R9VI.I configured a 3.2 Msps sampling frequency, which means that HAL_ADC_ConvCpltCallback and HAL_ADC_ConvHalfCpltCallback must be called each 10 ms for a 64000 elemets buffer.Ho...

RTC in STM32F302VE MCU Occasionally reset to initialize configuration time.

Hi all,Our product is build upon STM32F302VE MCU with ECX-34R (32.768KHz) crystal oscillator connected to PC14-OSC32_IN & PC15-OSC32_OUT and Panasonic CR1220 (3V) battery connected to VBAT.We configured the RTC via CubeMX and used RTC_BKP_DR0 registe...

What type of tranistors is used as power switches in the P-NUCLEO-IHM001? I found that for some other ST-family there are MOSFETs but can't find any information about the transistors in the STM32. If they are MOSFETs, are they NMOS or PMOS?

F767zi UART

I tried 2 demo printf using HAL and UART Tx using LL from your examples. LL demo runs ok and getting message display on Serial COM console. HAL printf demo got not message display. Any suggestion? I hv another board NUCLEO-F411RE works ok for HAL UAR...

STM32F205,UART DMA transfer stuck after a while

Hello to everyone,Thank's to the people who will take time to read my problem.To be short, I'm working on a system which embed a STM32F205 MCU. This system can communicate with other similar systems by exchanging UART messages over an RS485 physical ...

How to configure the Systick Timer to work with the HSE PLL?

I would like to develope a program for a custom board that uses an external 8MHz cristal oscillator and a STM32G441RBT6 as a MCU. I configure the HCLK to be 120MHz with the PLL but when I try to do a HAL_Delay or a TIM count it gets stuck not countin...

Use timer base and input capture at the same time

I use timer gated mode for a HC-SR04 ultrasonic sensor which needs microsecond delay. Is it possible to use the same timer as time base to get microseconds? if (HAL_TIM_Base_Start(&htim3) != HAL_OK) // time base for usDelay() Error_Handler(); if ...
