This is driving me crazy, whay timers on STM32 are so complicated and no normal information / datasheets etc, how to use.Timer2 is working (external clock), Timer interrupt (TIM_IT_UPDATE) also working, but not capture interrupt. And signal is also p...
Moved from this thread. What is the maximum amount of time required after bringing nRST high for a Pattern 11 MCU to determine that flash is blank, recognize that BOOT0 is high, and enter the ROM bootloader? I suspect we may have a timing issue, in ...
Hi All,I am successfully programming and debugging a NUCLEO-STM32F401RE by its embedded ST-LINK programmer using STM32CubeIDE v.1.12.0 on a computer running Ubuntu 22.04.3 LTS, updated and upgraded.I have a second PC running exactly the same Ubuntu, ...
Hello,We are working on a stm32f429.The application uses ADC1 to sample data on Channel 0-7.ADC1 and channels characteristics are:- Mode: Independant- Sampling clock: Around 2.8 Mhz- No DMA access- Sampling delay: 20 clocks periods (max value)- Resol...
Hi STM Team, We are using STM32H757XIH6 microcontroller in our design for one of the project. We are having the query regarding FMC port. We are planning to use 8 bit data bus (FMC_D0-D7) of FMC port to drive multiple peripherals like LCD, Keypad, AD...
I'm working with an STM32H7 board and trying to interface with some external RAM using OCTOSPI over the HyperBus protocol. I'm attempting to run the RAM in memory-mapped mode and have mostly followed the STM32 application note provided by STM.Most of...
Hello all,we are using the STM32H7S3Z8T6 in a project. It has four VDDxSPI pins for an external power supply if XSPI is used. I also found some information in app note AN5935.However, we are not using external memory and therefore we don't need an ad...
Hi, I am using an STM32H7RSxx device and I need to use the SPI6 (both full and half duplex) with the DMA.The problem I am facing on is the MOSI pin doesn't transmit anything.Only the SCK is working.Despite having configured it for SPI6 Alternate Func...
I am having issues with the STM32G0 ADC measurements. I am trying to measure 2 voltages:1. 3.3V2. 12VAfter the voltage divider, the 3.3_adc and 12v adc pins are connected to the MCU pins directly:3.3_adc - PA3 (ADC1_IN3)12v adc - PA7 (ADC1_IN7)My STM...
hi all,I'm Trying to send a string from STM32F401RE MCU to EPS32 Via UART i have programmed both STM as well as ESP32 and i successfully verified that data is available on UART pin of STM Data on UART Pins of STMBut I'm not able to receive data on E...
