BDMA -Availability depends on devices.

hello

ı use stm32h723zg and ı use bdma for adc3 , I was wondering if bdma can be used with adc3. I looked in the reference guide but couldn't find it. I will be glad if you help.

Data Sheet should indicate the H7xx devices having an ADC3

Will need to check later.​

I didn't fully understand what you were saying.

a) Not all H7 have an ADC3

b) I will look at the DS/RM when I'm at a computer

Part looks to have ADC3 on AHB4, and the BDMA should be able to use it provided the destination buffer is in the SRAM4 (D3 Domain)

Yes. BDMA is hooked up to DMAMUX2 per the reference manual. DMAMUX2 is connected to ADC3 through requests 26/27 (ADC3_IT/ADC3_AWD). See "17.3.3 DMAMUX2 mapping".
