Hello there,I’m trying to squeeze functionality into an STM32U5 MCU via the STM32CubeMX tool.After setting the pins, the clock configuration fails to find a solution.The requirements for the clock are to run from an internal source, as the design is ...

Using STM32L452CC and STM32CubeProgrammer API v2.12.0 Windows 64-bits.Firstly, I'm setting the readout protection to its middle level (RDP = BB in the programmer) and then program the chip successfully. Then, letting the chip power cycle. Now reading...

Using the IWDG within STM32L452 in its window mode.At some point the application needs to freeze the IWDG module functionality, or as a minimum make it work as in non-window mode.Is this possible? If yes, using which function?Note the I couldn't loca...

Solved. The way it worked for me is by changing the order of the resource allocation process:1. First, set the clock to your preferred value and lock it to this specific value.2. Set items that don't have pins flexibility: e.g. USB, JTAG.3. Add your ...

Try parametric search by ST's MCUFinder tool, I found it useful

Thanks, Peter,Understood. In these days of chip shortage, R&D are asked to provide alternatives, so that various chips could be used inside the very same product.It would be a production nightmare to program each chip with different firmware.Somethin...

Thanks to all responders, every answer helped to locate the missing bit which was this:LL_ADC_SetCommonPathInternalCh(__LL_ADC_COMMON_INSTANCE(ADC1), ADC_CCR_TSEN | ADC_CCR_VREFEN | ADC_CCR_VBATEN );I still get 41C at room temperature, which seems hi...

Does ST provide an example code driver for connecting its STM32L4xx MCU with its I2C EEprom M24C32-F?
