Can STM32F407VGT6U acts like STM32407VGT6?

I just bought STM32 Discovery Board with STM32F407VGT6U ICs, the thing is i use the stm32duino extension on arduino IDE, and on one laptop we can't upload it, on other laptop the Board can't send Serial data, previously i use the STM32F407VET6 series...

Resolved! STM32U5 and USB HS

Hi allI'm configuring STM32U5A5VJT to work with the USB HS crystaless. From the Cube it seems to be possibile to use one of the integrated oscillators as clock source for the USB HS but this is not mentioned in the datasheet.I'm afraid that it could ...

Resolved! Mixed interrupts in the vector table

Hello,I'm looking the vector table described in the Table 97 of the STM32G4 series reference manual, and it shows interrupts with different characteristics, such as TIM1_BRK/TIM15 and TIM6_DACUNDER, being allocated to the same address. This is very c...
