Wiring & Test

You can easily wire this breakout to any microcontroller, we'll be using an Arduino. For another kind of microcontroller,

as long as you have 4 available pins it is possible to 'bit-bang SPI' or you can use hardware SPI if you like. Just check

out the library, then port the code.

SPI Wiring

Since this is a SPI-capable sensor, we can use hardware or 'software' SPI. To make wiring identical on all Arduinos,

we'll begin with 'software' SPI. The following pins should be used:

Connect Vin to the power supply, 3V or 5V is fine. Use the same voltage that the microcontroller logic is based

off of. For most Arduinos, that is 5V

Connect GND to common power/data ground

Connect the SCK pin to Digital #13 but any pin can be used later

Connect the SDO pin to Digital #12 but any pin can be used later

Connect the SDI pin to Digital #11 but any pin can be used later

Connect the CS pin Digital #10 but any pin can be used later

Later on, once we get it working, we can adjust the library to use hardware SPI if you desire, or change the pins to

other
