I have quite a complicated case, where a interrupt is beeing executed, allthough it has been disabled, and its flag beeing cleared. At the same time interrupts are disabled, and i put a few nops in between just to rule out any delay related issues. T...
Hello all, We are evaluate STM32H745 for one of our new products. Dual core feature of STM32H745 is something we would like to use. As a part of initial process, I was trying to debug both M4 and M7 cores simultaneusly.Following AN5286, I was able t...
We are trying to develop a device that uses SPI communication (Transmit Only Slave).Are there any sample programs for SPI communication (Transmit Only Slave)?What should be the trigger for calling HAL_SPI_TransmitReceive? Master's CS?
Hello,I would like to use 2x AD7606 for simultaneous sampling of 8 channels, the samples shall be sent to the STM32H753 CPU that will perform some DSP calculations. This system is intended for 3-phase grid monitoring system.I preferred the SPI mode r...
I am currently working on a board designed around the STM32H725RGV6 and have encountered issues with it being recognised by STM32CubeProgrammer as I get the message "target not found" when connecting it to a STLINK-v3-minie. With my previous experien...
Hi, I have an STM32303E-EVAL that I have been messing around with, but I also want to reset it to the demonstration functionality. I have downloaded the zip file for the demonstration firmware from the website, but I am not sure where to go from ther...
Hello I am using : STM32L031G6U6.I am confused how programming the MCU works. I don't have let's say SWDIO and SWCLK pins declared in CubeIDE. Then how it works ? Why it works this way ? I read something that when I use NRST pin to reset manually the...
I'm starting to learn about low-level embedded development. My goal is to learn how I can write my own linker scripts and startup code. I also want to learn how to use raw register calls to do something useful. I want to use the NUCLEO-L011K4 board a...
I have two questions regarding RM0440 Rev.8, Figure 195:In Figure 195, it shows that the roll-over events invert the push-pull logic. A roll-over event is defined as "a counter roll-over event is generated when the counter goes back to 0 after reachi...
I am able to use the demo code as is to send characters to TeraTerm but when I try to use scanf to get inputs from TeraTerm, i get nothing. when i debug the code, i see that the function doesn't for user entries and just go to next line in the code. ...
