Resolved! Nucleo-U575zi-Q ADC reading garbage values

I'm new to the stm32MCU. I am using a Nucleo-U575zi-Q board. I am trying to read ADC values by setting the built-in DAC. I have check my DAC out and it is working fine. My ADC reading is giving me garbage values. I have set HAL_PWREx_EnableVddA() als...

Resolved! STM32L4 current consumption is more than expected.

I am working with a NUCLEO_l452RE, temperature 25°C, 1.8V, and I am measuring current on JP6, so I tried to reproduce: I set up MSI@1Mhz, I got 280uA, much more than 100uA which I was expecting.Later with MSI@24Mhz, I got 3.24 mA, 135uA/MHz, closer t...

Reference pierce oscillator design available for STM32G0B1x?

I'm developing a new design with a STM32G0B1x uC. Therefore, I will use a 12MHz or 8Mhz external (HSE) crystal quartz from Abracon. I just read through the AN2867 and did some calculations. Now I'm at the point where I would need to measure the drive...
