hello everyone I am new to this stm32 series i purchased the stm32g0b0ret6 controller and now i am using stlink version v2j40s0 but i am getting the error no target device found can anybody guide me for that
Hello,I am using STM32L412 Microcontroller in my current project.As shown in the attached image in the Application Note "AN4555" for STM32L412,For additional Precautions, VDD should be connected through Ferrite Bead at the VDDA pin.So, my question i...
I have a NUCLEO-L432KC like the title says and I want to power it from an external source. I am using the ST-Link debugger as an 8mhz clock input, and when the st-link is not powered it pulls the RST pin low and I don't get my 8mhz clock input. I hav...
what is U2A i see in top of the schematics?What is the diffrent between U2A and U7A? thanks
I have 11 boards of our prototype with the STM32L4A6AGI6 (i.e. 169 BGA) assembled. 5 of them work fine. The other 6 eventually loose debugging connection. It doesn't happen immediatelly i.e. I'm still able to run a few lines of code but then it reset...
NUCLEO-U575ZI-Q is based on a STM32U575ZIT6Q in LQFP144 package. A diagram on page 98 of the datasheet shows PC5 (pin 45), PB12 (pin 73), and PC4(Pin 44). None of these I/Os are exposed on the connectors of the NUCLEO-U575ZI-Qhttps://www.st.com/res...
I am using custom designed board having STM32H745BIT6 and 25MHz external crystal with LDO and SMPS pins connected as seen in attached snippet.I have created, compiled new STM32 project using CubeIDE and CubeMX software for LED blinking.Attached .IOC ...
Hello all,I am using STM32L431 in this project, and I have made a prototyping board for it. However, the MCU will not communicate with the debugger.Below is MCU part of schematic:Only SWDIO and SWCLK are connected to the debugger. The MCU is powere...
I have STM32L4P5CGU6 (48 pin).Pins PB5, PB4, PB3, PA15 are used as SPI1 with another IC which has 3.3V levels.As well as PB6, PB8, PB9 as custom input GPIOs with voltage levels of 3.3V.VDD (pin #9, pin#24, #48) -> 1.8VThey all seem to work fine, howe...
