Wb55 - How to read values from ADC

Hi everybody!

Working on Martian Robot développed by VittaScience​, I need to read values coming from 5 blackline sensors to the ADC of the wb55.

I tried to analogRead() the pin but nothing...

Some ideas?

Thanks!​

Just tested on 500Kbit/s, works fine for me. Please check the wiring and SPI configuration: master mode, full duplex, datasize 10 bit and enabled NSS signal on PA4.

Hi @Jaroslav JANOS​ ,

It works fine, thank you very mutch, I missed NSS Signal on my configuration.

Now I isolate all the values for each sensor but the values seems to fluctuate a lot with the light .

Just need to find an algorithm to detect the lines now...

Thank you!
