Hi,Got a new MCU with LSI2 from the distributor. I want to use it for the 2.4 GHz RADIO sleep timer, but can't find LSI2 register settings in STM32CubeMX.Additionally, I'm curious why the STM32CubeWBA version V1.3 doesn't support the STM32WBA52 serie...

Recently, I studied STM32WL series and want to design board by myself, so I reference MB1789-HP files to design. I have some questions about sch and pcb files, I know MCU pin 21 (RFI_N) is connect to C30 capacitor, but in PCB file, MCU pin 20 and pin...

Hi @Sarra.SI got the file, but I have a question confused me, I compare others demo board files, such as MB1720, MB1791, MB1792, MB1842. Their schematic and PCB file are macth to each other, and they don't need to change MCU PIN20(RFI_P) and PIN21(RF...

Hi SarraI hope to get good news from you soon.

You don't feedback rotator position and motor three phase current. Are you doing open-loop control strategy ?If it is true, you can't let motor operate in high speed range or having heavy load, because the system will close to unstable region easil...

Hello There are many reason cause motor rotate unstable. What kind of motor do you use? What about motor rotator feedback sensor? The motor three phase current using shunt resistor or other methods?
