I'm having an issue with connecting my Nucleo board STM32L552ZE-Q via USART3 to both a terminal and SerialPort. I configured the timer and USART3, but I'm not getting any output on the terminal or in SerialPlot. I’m not sure where the error might be....
I have several NUCLEO-H755ZI-Q boards, the documentation says that the clock coming out from STLINK should be 25MHz but I meassured STLK_MCO and found an 8MHz signal... on SB72 to be more precise.The sticker on the boards sayNUCLEO-H755ZI-QNUH755ZIQ$...
Hi All, sanity check sought:I'm using the blue pill (STM32F103C8T6) for a audio project powered & controlled through the serial/USB.I'm using the STM32 cube and a dev board for the s/w which looks ok; in terms of software I've followed https://contro...
Hello,I have been working with a Nucleo eval board and have not had any problems with the ST-Link connection. Recently I got an ST-Link/V2 ISOL dongle to use with a custom board using the same chip, and have been unable to connect with it. There seem...
I want to stuff the extra connectors so that I can plug the nucleo onto a backboard, but I want to make sure that they are the same length.. I have been unable to find what appear to be compatible connectors in stock anywhere?. This has to be a fre...
Hello, I have a custom PCB with STM32F427VIT6. Been reading and learning a lot about MCU's in general. I'm very new to all of this so please bare with me.When PCB is connected to the PC via usb, it shows up as HID device (it emulates gamepad/controll...
Hello, I'm working on a canbus project and I'm trying to read some data on the nucleo to confirm that my hardware setup works good since it's not a common use. At this point:- MCP2515 communication via SPI with the RPI5 and it's well configured. - I...
I am working on a project using the built-in LCD display of the STM32H747I-DISCO board. However, the display output shows unintended thin lines and color distortions, appearing as if the colors are breaking. I am unsure whether this issue is caused b...
Good day Folks,I am trying to get a simple program working on the STM32N6 Nucleo board, however when debugging an interruptoccurs causing the code just to get stuck in the Default Handler.I am not sure what interrupt is triggering it.This is most lik...
Hi,STM32N6570-DK preloaded code works with the default MB1854B camera board. My question is:"Does the default firmware support VD66GY?" I tried and could not make it work.When I switch the camera module to VD66GY S-BOARD, the LCD shows "Camera not de...
