Is low impedance for the ADC input good or bad?

I have noticed several recommendations on internet, that recommend providing a low high frequency impedance driving the ADC input for the MCU. For instance, you could add an RC-filter with the capacitance directly between the input pin and analog gro

SWV ITM Console is not Enabled...Why Not?

I had created a Project using STM32Cube MX/IDE (versions 6.17 and 2.1.1 respectively)in which I had set up the SWV ITM Console as the output of printf().This was working as expectedThen, I moved the same project to a new machine under STM32Cube MX/ID

Uploading the Program on STM32G0B1KEU6 using STLINKV2.

Hi everyone,I'm currently bringing up a custom board based on the STM32G0B1KEU6 (UFQFPN32) and I'm stuck at the very first step. I can't get the MCU to respond over SWD.I'm using STM32CubeIDE with an ST-LINK/V2, and every attempt to connect gives me:

Min LSE Clock Speed STM32U5

The table in the datasheet says that the minimum frequency for LSE in bypass mode is 5kHz (Table 71 of DS13543).In previous designs (different STM32 MCU) I have successfully used a 125Hz input for the LSE (setting async prescaler to 1 and sync presca

Guidance Required – ST-LINK V2 Not Working After Inverter Board Failure

I need your guidance regarding an issue I encountered while working on the customer inverter board.While testing the board, I applied a sudden ramp-up in open-loop mode. Due to the high current spike, the inverter board got damaged, which I understan

CSI_PFCR.DLD bit description contradicts HAL implementation

RM0486 describes CSI_PFCR bit 16 (DLD) as follows: Bit 16 DLD: Data lane direction of lane 00: Rx1: TxPer this description, configuring the CSI-2 host to receive from a camera sensor (i.e. lane 0 in RX mode) should require DLD = 0.However, in the shi

STM32U575 freezes when exiting STOP2 mode after power cycle

The MCU works fine the first time it gets programmed. However, after one power cycle, it freezes completely after an external interrupt happens. Doesn’t even enter the error handler. I have SMPS enabled. Thanks for your help int main(void){ /* USER
