Hi,

I want to use multi channel SDADC in STM32F373.

First,

Can I use Multi channel  in SDADC1 using regular conversions?

In case of SARADC, it is operating scan mode. But i can't find scan mode in SDADC.

Second,

If regular conversions is not provide scan mode,

only injection mode provide 

Multi channel?

Third,

There is no example code about Multi channel SDADC.

Can you give me some example code using 

Multi channel SDADC?

#stm32f373 #sdadc

Hi,

You can refer to the

http://www.st.com/content/ccc/resource/technical/document/application_note/a0/8e/94/50/ae/d2/4b/5e/DM00124123.pdf/files/DM00124123.pdf/jcr:content/translations/en.DM00124123.pdf

and

Application note Getting started with STM32F37x/38x SDADC (Sigma-Delta ADC)

The

SDADC examples are available as part of 

the

STM32F373 SDADC 

http://www.st.com/content/st_com/en/products/embedded-software/mcus-embedded-software/stm32-embedded-software/stm32-standard-peripheral-libraries-expansions/stsw-stm32114.html

 

package and Standard Peripheral Library STSW-STM32115 following the UM1565 'Description of STM32F37xx/38xx Standard Peripheral Library' to have more details on how to use this driver.

You'll probably want to review SDADC examples as you can find under STM32CubeF3 firmware:

STM32Cube_FW_F3_V1.6.0\STM32Cube_FW_F3_V1.7.0\Projects\STM32373C_EVAL\Examples\SDADC

Hope this help you.
