Commissioning SPI via the Discovery Board
To establish a connection with the NP5-40, proceed as follows:
- Plug in the NP5-40 at X8.
- Unplug jumper X13.
If you would like to address the controller via USB (virtual COM port), install the Nanotec_ComToSPI driver and connect the USB cable to X4.
If you would like to address the controller directly via SPI, connect the SPI master to the controller via the SCK (source clock), MOSI (master out, slave in), MISO (master in, slave out) and CS (chip select) cables. Check that the earth (GND) of the master is connected to the earth of the controller.
- Connect your supply voltage to X7.
