About NUCLEO-F446RE current consumption
Dear Sir・I want to use NUCLEO-F446RE as a PoC for IoT.・I plan to use alkaline batteries and connect to CH6 PIN4. (3.3V)⇒It is necessary to reduce the current consumption.I investigated with a simple FW.(Use stabilized power source(SPS))Case:Run Mode(...
Is it possible to compare compare the output using STM32's timer interrupts
I am currently learning to use timer interrupts using the HAL library on the STMF769I-DISCO. I am trying to get the interrupt to activate when it reaches a certain value. From my understanding, the interrupt activates when the counter period overflow...
Troubles with flash programming on STM32G474RE. Can`t write anything to bank 2.
Hi everyone, i`ve got trouble with InApp flash programming on STM32G474RE. While i`am trying to load some data to address higher than 0x08040000 (Bank 2) in dual bank mode by the internal bootloader (placed on address range from 0x08000000 to 0x08005...
stm32g071 HAL_I2C_Slave_Seq_Transmit_DMA DMA TC flag is set even if one element less than requested was transferred
I am using a stm32g071 as an I2C slave.Problem is, that I2C_SlaveTxCpltCallback() callback is called even when the master read one byte less than previously configured.I.e. With RXSIZE = 4 (as in code below),if master reads 1 byte -> okif master read...
Resolved! Issue With Discovery Kit Debugger
Hi, I have a problem with my discovery kit stm32f072.I usually use that board as a debugger for my personal embedded projects, so only the debugger part.I recently tried for a moment to download my project to the discovery MCU and since then, when I ...
Why is my buffer corrupted when for-loop is split up?
Hello,I have a project on a Nucleo board that samples the ADC and typecasts the result.The typecasted value and the original value are sent via UART and virtual com to my PC.When I put this code in a single for-loop, I can receive both the raw and co...
STM32H7 - external SDRAM on FMC - optimal configuration for code execution
We have a STM32H745 MCU, an IS45S16320F SDRAM on the FMC interface, which is used for a Codesys application code execution.This is the SDRAM init:/** Perform the SDRAM1 memory initialization sequence */ hsdram1.Instance = FMC_SDRAM_DEVICE; /* hsd...
