The Serial Peripheral Interface (SPI) is a communication bus that is used to interface one or more slave peripheral integrated circuits (ICs) to a single master SPI device; usually a microcontroller or microprocessor of some sort.
SPI in OpenMV Thing board can be defined on the following pins:
You can see these SPI pins on OpenMV board, shown in Figure below.
We can use SPI on OpenMV board with SPI master and slave modes. We develop program based SPI using SPI library, .
In this chapter, we build a SPI Loopback app. Let's start!.
