6.4 Testing
Now you can run the program to OpenMV board.
You can open Serial Terminal from OpenMV IDE. The following is a sample output.
7. Working With SPI
In this chapter I'm going to explain how to work with SPI on OpenMV Thing board.
7.1 Getting Started
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:
- MOSI on pin P0
- MISO on pin P1
- SCLK on pin P2 (SCL)
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!.
