I am running macOS Sonoma and using PlatformIO within Visual Studio Code.I have multiple STM32 microcontrollers connected via ST-LINKs to a USB hub¹. My ST-LINK USB devices are correctly listed in 1) the USB Device Tree within the macOS System Inform...
Hello all,I am trying to establish communication between an SM-UART-04L dust sensor and an STM32F411RE MCU. The output of the sensor (attached image below) does not use the regular sized jumper wires that connect to the MCU and has a 2x5 pin configur...
I have written quite a bit of code to familiarize myself better with Azure FileX with 192K sram, and so far, it is working well under ThreadX. The Azure FileX documentation made clear that FAT12 has a maximum number of bytes of 4096 per filename whic...
Hallo,is there something I have to check if ITM_SendChar doesn't work? I mean, I have overwritten the write function in syscalls.c and enabled in the debugger settings the swv viewer at the correct clock, enabled swv trace (the same things I did usin...
Hello,I have programmed a Nucleo-L476RG with the Blinking LED example. Until there is all fine.Now, I want to load a new program on the board. Windows Explorer and ST-Link do not detect the board and cannot load a new program on the board.I bought th...
I see this note in the user manual for the STM32U5A9J-DKIs it possible to enable 3.3V output for the GPIO on the CN9 header by removing SB56 and jumping the 3V3 pin to IOREF, or would this damage the board or not have the effect I intend?
I got this error while uploading the code and I tried using ST-link utility to erase the memory but no success. How do I troubleshoot it ? :unamused_face: Thanks in advance.
My Nucleo-G031K8 can no longer be programmed using STM32CubeProgrammer or from STM32CubeIDE. When attempting to connect using STM32CubeProgrammer I receive the following text: UR connection mode is defined with the HWrst reset mode Error: Est...
I am using a STM32H743 processor and have ST's LwIP stack running correctly. At least to the point were I can use Hercules as a client and connect to the Nucleo and send a small block of data (24 bytes) to the Nucleo. I have set breakpoints in the co...
Hi everyone,I just picked up a STM32F746G discovery board to practice on, but I can't for the life of me get the built-in STLink to show in windows. By this I mean, I'm unable to power via mini-B and LD7 just flashes red. Once I change the jumper on ...
