Hello,For my project I am working on two nucleo board H743ZI2.Unfortunately, during an experimentation one of the boards ceased working (LD4 and LD6 red). Maybe a short circuit, I don't know.Anyway I tried to purchase a new NUCLEO-H743ZI2 but it seem...

Hello,The main purpose of the question is to avoid giving source code and give binary file instead.For example, I generate a compiled binary file from a nucleo project (STM32H743ZI2) for the M7 core.Then I want to create a new dual core project (STM3...

Hello, I am using a nucleoH743ZI2 and STM32CubeIDE v1.13.2 on windows10I configured the USART 3 in order to receive some telecommands from my laptop (windows 10) using a software (HTerm v0.8.9)The telecommands are written in binary, 52 bytes, but the...

Hello,I am using a NUCLEO-H743ZI2 and program on the STM32CubeIDE1.13.2The purpose of my project is to create a 2kHz sine and to sample it at 40kHz at the same time.I would like to have no delay between the 12bits DAC and the 12bits ADC: that the fir...

Hello,I am using a NUCLEO-H743ZI2.I read the reference manual RM0433 Rev8.I also read a bunch of topics in the forum but didn't find what I wanted. I am trying to check my ADC sampling rate by looking at the timestamp at my half full/full callback fr...

Thank you for the answer, I will try to directly upload the same project on the new card and hope it works !

Hello,I replaced the use of the DMA by a simple IT because easier to use.Thank you Karl for the hint, I followed this tutorial which explains how to do:STM32 UART #5 || Receive Data using IDLE LINE (controllerstech.com)

Hello,Sorry I didn't understand your scheme: waiting for TIM1 to be bigger than ARR/2, how to program it ? is it in the main.c or the .ioc ? Isn't the condition the same as smaller than ARR/2?I made a few more tests and it seems like starting hardwar...

For the spectrum of the sine, I forgot to write that the Y axis is in dB, so the harmonics are 50dB lower than the fundamental which is ok for my application.I can lower the peaks of the harmonics by 20dB by lowering the amplitude because it got satu...

Hello,Yes, I also tried to compensate the delay manually by starting one timer later than the other one (by using a fourth timer which I adjust the counter) but the phase didn't change as expected.I don't really understand your lines of code: __dis...
