How to output two DACs through stm32?

I have a STM32-G071RB. I want to generate two sine outputs. one for reference and the second with a phase shift. Unfortunately, there is only one DAC port. I got an extra board but then I realized I need communication between the two boards to (I fou...

UART communication problem. No reception

HelloI am trying to communicate with a Daly BMS in UART. I tried at first with an arduino board where I got the desired frame but when I tried with a custom made STM32F072 board. But during this test I can't get any response from the BMS.The BMS work...

What is the difference between FDCAN1 and FDCAN2?

Schematic for Nucleo STM32F072 has unconnected jumpers.

I've noticed that the Nucleo STM32F072 has two jumpers (CN11 and CN12) that connect ground to ground. Does anyone know why this is? Are these jumpers used on another Nucleo board, and just hang out on the STM32F072 like a lot of the unconnected sol...

STM32 MCU UART TX current

I am connecting the STM32L4 MCU UART to silicon labs IC CP2105 (UART to USB converter). The UART to USB bridge is bus powered from the type C connector and the STM32 is separately powered from the battery. When the CP2105 is in off state ( No USB ca...

We are using STM32G431RBT6 Break Input .I have configured the Break input and it is working fine .When Break Input is Low ,the PWM is ON. After Break input is High ,the PWM is OFF ,Now if we give Low to the Break input No PWMs are Generated.
