STM32f373 SDADC multi channel error.

Posted on December 07, 2017 at 05:43Hi, I use 3channel of SDADC in injected mode.My error is SDADC value is saved anothor variables.SDADC1 result -> saved at SDADC2 variable.SDADC2 result -> saved at SDADC3 variable.SDADC3 result -> saved at SDADC1 ...

STM32F373 SDADC - wrong values

Posted on October 19, 2017 at 04:22Hello everyone,Could I please get a little bit of help with getting the STM32F373 SDADCs working?The chip is an STM32F373CBT6, with VREFSD+ and VDDSD both connected to VCC (3.3V). I've followed the ST guidelines on...

stm32f373 sdadc switching configuration

Posted on October 04, 2017 at 13:01 Hello everyone! I'm working on the project with an STM32F373 microprocessor. I'm using all three SDADC-s simultaneously. SDADC3 works constantly in Injected scan mode with frequency 16,66kHz. SDADC1 and SD...

Question of SDADC Gain of stm32f373

Posted on August 01, 2017 at 02:32Hello,In the AN4550 , chapter 5.1.1 SDADC from HW design describe SDADC gain.I confuse about difference between analog gain(0.5 2 4  and digital gain(16 32).Is the Analog gain change the gain using MUX?Is the Digit...

Question of STM32F373 SDADC Multi channel concept

Posted on April 04, 2017 at 15:08Hi,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...

STM32F373 SDADC injected conversion order

Posted on July 01, 2016 at 12:30Dear ST Team, along another issue I found in the F373 SDADC code, I saw a strange behaviour of the SDADC against the description in the F373 reference manual. My software samples some sensors connected to multiple cha...

Triggering SDADC (stm32f373) from RTC (LSE)

Posted on September 22, 2016 at 15:19Hello, I have a project based on stm32f373, I'd like to trigger sdadc conversion with RTC synchronyzed frequency, are there any solutions to do this without external routing MCO output(LSE) -> Timer Input -> Trig...
