I'm using the STM32U5 and when I create a basic project in Keil and compile, I get the following error:"Error: L6218E: Undefined symbol SECURE_SystemCoreClockUpdate (referred from system_stm32u5xx_ns.o)."How to fix this?I don't want to use STM32Cube ...
Hello, I'm trying to set up SPI communication between an MCU as master and the STM32 as slave. Data reception in the STM32 works fine, but I'm not being able to transmit data to the MCU from the STM32. I'm using the interrupt callback to read and sen...
Hello,I'm using STM32 NUCLEO board.In my application, I want to read GPIO PORT A input register (IDR) & (pins setup as inputs).With that variable, I want to do something, if specific pins are HIGH, execute the if cycle.As an example, I want to execut...
I have my MCU running at 1.8V and in I2C operation mode I have disabled the internal pull ups on the pins. Externally I have added pullups to 1.1V as my target device has been operating at 1.1V. Will this cause any issues?

Hello STM32-Community,I'm getting mixed results checking up this question. In the power consumption calculator (PCC) there is the following diagram displayed:As you can see it should not be possible to enter STOP2 from LOWPOWER_RUN. However the seque...
