How does stm32H723 ADC ISR know which channel ?

I am just getting started with the stm32h723 ADC.    If I create a regular sequence group of several input channels, how does my ISR know which channel was sampled last (which channel's data is in the DR)?  I don't see this in the registers.Thanks,Ma...

Resolved! ADC is slow using HAL

I am measuring time time it takes to do ADC conversions on an STM32H753ZI Nucleo board, using the function function HAL_ADC_Start_DMA().  This converts 6 channels of ADC3, using 16 bits, with DMA.  The one function call handles everything including D...

Resolved! G071_SPI2-MOSI is not output on PA4.

I’m working on a program to transmit data over SPI1 and SPI2 using DMA. For output I only use each peripheral’s CLK and MOSI lines. SPI1 and SPI2 differ only in the exact data being sent—their configurations and the number of bytes are identical. Als...

Stm32 usb host questions and recommended mcu

I am looking at a project where I would typically use an SBC, but wondering if ST has enough usb host support to accomplish this with existing usb stack software.  If so what would be recommended models?   Will be used as a usb host only (role change...

Resolved! SPI DMA Memory to peripheral

Hello everyone, I'm currently working on an SPI bus on an STM32U031C6 + S2LP. I'd like to use my SPI with DMA mode. The SPI bus I used previously worked on this board. As this is my first time using DMA, I'm simply trying to send data without necessa...

The consumption of Vcap about the STM32H723

Hi ST expertI'm ready to use STM32H723 now. Vcores can use internal LDOs or external power supplies via Vcap pins. If you use an external power supply, what is the current of the power supply, I see that there is only Idd in the datasheet.Thanks
