I quite noob, but I hope you can bear with me and answer some of my (dumb?)questions
I have a Particle Photon, and Poloulu QTR-8A (analog) line sensor (hooked up form A0 to A7). I am building a line folowing robot (it is built I just need to make the code work)
I would like help to configure right settings for the ADC to get best results. The smartsensor library seems awesome for that purpose, but there is so much variables to set...
Reading the STM32 documentation http://www.st.com/web/en/resource/technical/document/application_note/CD00258017.pdf
I can find that the STM32 in Photon has 2 DACs and many different modes. How are the DACs configured in Viperize can the modes be changed? I know that Spark(Particle) core used (or still may use) Dual slow interleaved mode to increase the ADC impeadance, but it totaly messed up reading of some sensors.
I would like to sample every sensor from 500 to 1000hz (8 sensors x 1000hz = 8000hz) is it possible or am I asking too much from the ADCs?
