Hi,I making a product that has the STM32U5 running from a battery, most of the time being in one of the low power modes. I can use the debugger to .. debug my code, step through it, use SWO etc, and this all works great. However, as long as the debug...
Hello, i am trying to run a simple code that toggles the built-in led when i press the built-in user button. I wanted to do this manually using HAL library functions, but for some reason i do not seem to get it right somewhere. The code generated usi...
Hi, I am using the STM32H563ZIT6 microcontroller and trying to interface it with an internal DAC to a speaker through an external MCP601 op-amp. I am generating a sine wave on that DAC pin, but it is producing some noise in the speaker. I am unsure h...
I have a 3d printer with a Btt skr pro v1.2 motherboard. The Sd card slot is non functional so looking to update the firmware directly.can I use a st-link v2 to upload the firmware from the pc to the motherboard? the motherboard has a stm32 controlle...
Hi,I'm willing to use the MXCHIP EMW3080B wireless module on the B-U585I-IOT02A in a project with TrustZone enabled. As there is no tutorial for that, I copied files from the Nx_Network_Basics example.Unfortunately I get the following error when buil...
Hi, I'm encountering a general issue with DMA on the STM32H743 processor. I'm having trouble with SPI and I2C communication when using multiple integrated devices. For instance, when attempting SPI DMA communication with the W5500 integrated circuit,...
Please confirm the default state of BOOT1 pin state through nBOOT1 bit for BOOT configuration. How can we pre-configure nBOOT1 bit for BOOT configuration?
Hello everyone, I am a student who is fairly new to these concepts so I wanted to pick your brains for a bit if you'll allow me to. I have done some research and found that STM32F4 is compatible with AT commands if we use external hardware. However, ...
Dear ST, In UM1974 rev 10, section 6.8.1, page 25/84 a recommendation is given for the use of a particular crystal part number: This part number does not exist. I've searched on both Digikey and LCSC and in both there is only the part numberNX3225GD-...
Hello everyone. I am getting started with SPI and am here with what I believe to be a pretty simple mistake or oversight on my part that I am just not seeing. For the first part of this project, I wish to create a file named "write.txt" on my SD card...
