Hi, thereI'm trying to integrate the STLINK-V3MODS with my STM32H745 based project.The STM32H745 MCU is powered by an external 3V3 output regulator.The STLINK-V3MODS board has the following edge pin:Which is described in the manual as an "Input for S...
I'm trying to implement a RTC using the LSE crystal of Nucleo-h743zi board (Rev.B model). In addition, I want to backup the timestamp in case of power loss. Following the reference and user manuals, I finally have my RTC worked, using RTC backup regi...
Hello,Just got a new Nucleo-H563ZI board and I was trying to connect it to PC through the STLINK USB-C port, in order to play with it. I've checked jumper config, and all seems right, but the only thing happening when plugging in is that LD4 RED half...
Hallo, how to determine the file presents in a folder with filex?What function is available?
I have a STM32L475 IoT Development board which I'd like to get working with Cube IDE & Azure IoT Hub. Anyone got a migrated example?. I can see the old project on Github which is meant for the old SW4 IDE, but when I try to import it to CubeIDE, or ...
Can you open source your STLINK-V3MINIE? All hardware and codes, Your design is not easy to use.
Hello Community, I am using the STM32U585 in a design, and I have VDD at 3.3V and VDDIO2 at 1.8V. The 1.8V rail is supplied by a 3.3V to 1.8V voltage regulator. I connected the Enable of this voltage regulator to one of the STM32U585 I/O (this I/O i...
Hello,I've developed a custom board based on the STM32H573RI MCU. Everything on the board is operating properly except the USB C, which is far from working out of the box.The problem that I'm experiencing is that after the initialization (enable the ...
It looks like the BSP_SD_IsDetected function from the sample codes is working backwards. According to the SD-Card spec this pin has a weak pullup (50 kΩ) inside the card. So the STM32 should have a weaker pull down on the pin and detect the presence ...
We developed our code using the NUCLEO-H743ZI2 (MB1364-H743ZI-E01) where printf over SWO worked great for debugging. Now that we have ported our code to our custom board using the STM32H743IIK package, SWV no longer works. It won't even launch (see...
