STM32F1xx: Injected simultanous ADC doesn't work

Posted by stancecoke on 2019-01-18 09:08

I want to read in two phase currents of a BLDC motor, simultanous with injected ADC1 and ADC2 triggered by Timer1 Capture Compare Channel 4. See chapter 5.1 of the STM manual UM1052:
https://www.st.com/content/ccc/resource/technical/document/user_manual/5e/5e/d2/cb/07/35/45/a6/CD00298474.pdf/files/CD00298474.pdf/jcr:content/translations/en.CD00298474.pdfQuestion

The basic setup was created with CubeMX. You can find the whole project at github.

The interrupt of Timer1 Capture Compare Channel 4 works properly, but no injected ADC conversion is started :-(

If I start the conversion by software in the Timer1 Capture Compare Channel 4 callback, it works.

Any ideas?
