STM32H7A3RIT6 Voltage reference buffer (VREFBUF) I’m using HAL_SYSCFG_EnableVREFBUF(); HAL_SYSCFG_VREFBUF_VoltageScalingConfig(SYSCFG_VREFBUF_VOLTAGE_SCALE0);To select internal vref 2/5 voltBut it seems that the ADC takes the voltage of 3.3 w...

I applied the program on stm32F4 and it works great I get DFU without problemBut on STM32H7A3 it doesn't work, you used the H7A code, which means address 0x1FF0A800USB in VPC mode and communicates with the computer properlyBOOT0 line with 510 ohm res...

I checked on cubeMX the 144 pin version has the option to select an internal reference voltage, while the 64 pin internal reference voltage is blockedSo there is a mismatch between the specification of the component and the actual performsMy test : 3...

In my circuit VDDA is connected to 3.3 voltsI want to use an internal reference voltage of 2.5 voltsAccording to the specification of the componentVREFBUF control and status register (VREFBUF_CSR)Bits 6:4 VRS[2:0]: Voltage reference scaleThese bits s...
