Hello there!
I am having a problem with this SAMD21 board. *here is schematics:(http://kit.sciencein.cz/wiki/images/b/be/MainBoard_v2.0_RevB_SCH.png)
There are two SPI pins - "MISO" and "int MISO", for instance. In the attached code, I am controlling the devices connected to int SPI pins in setup and loop. In the OZONE2CLICKCalibrate / Measure, I am trying to run my Ozone sensor, but when I run it, SAMD21 will lag - it is big lag, I have to completly restart the device.
Is there any way to controll the SPI?
