32F417: Any way to make an SPI SRAM to look like normal RAM?

What I am after is trapping an invalid address access e.g. at 0x30000000 and reading or writing 4 bytes from an SPI SRAM.The invalid address trap does trap the access but do you get the address you attempted to access and (if writing) the data word?I...

Hello, can anybody tell me the maximum allowed voltage flowing into STM32 when in Open-Drain-mode on an STM32G030F6? The datasheet does not show any overvoltage protection diodes, so I am wondering if it is possible to sink 12V limited to 50µA?

The concrete use case is that I want to control a p-channel-MOSFET which gate is pulled up to 12V via an external 10kOhm resistor.To switch the MOSFET I have to pull the gate down to GND, so I thought about using Open-Drain-output mode to let the 12V...

ST-Util GDB Server Quit Unexpectedly. See gdb-server output for more details.

Hi,I'm want to do a step by step debug of the project "https://github.com/aws/amazon-freertos"/(varient), I have installed VM on windows 10 and using vs code I want to do a step by step debugging. I have installed the GDB and all relevant tools in ub...

Memory leak detection or profilers

I am using STM32CubeIDE suite of tools on windows. MCU is STM32F4. Debugger is ST-Link V2.Is there a way to identify memory leak in the code i wrote for my MCU ? Preferably in STM32CubeIDE as its through this tool I upload & debug firmware for MCU.I ...

How to improvement work flow efficiency on dual-core µC such as STM32H7 in CubeIDE?

My debug workflow feels pretty inefficient and I was hoping to learn from this community how to improve it. My code framework is built using the embedded CubeMX which leads to default code where the CM7 starts the clocking while CM4 is waiting, then ...

How can I send an array of bytes using UART?

I need to send 4 bytes of data (array of 4 bytes) to the PC using UART. How to do this? Thank you

STM32H743VIT6. FMC for SDRAM

Hi,Is SDRAM over FMC supported in STM32H743VIT6 MCUs? I can't see this option in CubeMX, only NOR Flash/PSRAM/SRAM/ROM/LCD and NAND Flash. The datasheet says that SDRAM is not supported in LQFP144 packages, but my one is LQFP100.Looking forward for a...

I am trying to Debug and Run LED Blinking code with out IDE. I Debug and Run code with IDE it was working.Can any one suggest how can i do this through command line? I use STM32 -NUCLEO-H745ZI-Q board

How do you specify GPIO ports and pins as function inputs?

I am new to STM32s programing in general and am trying to create some simple libraries, altough I have no idea how I would make it so that I can write it in a way, that needed ports and pins are given in function inputs. For example: int HCSR04_Dista...

Processing time with STM32H7A3 differs depending on the variable.

Hello.I am developing with a STM32H7A3.When dealing with local variables or global variables when executing test code on the microcomputer, the processing time when using global variables is about twice as long as when using local variables.Is this p...
