SPI Dot-Matrix

How to use SPI on ODROID-C2

Since the C2 doesn't support Hardware SPI. This Example is using the GPIO-based bitbanging SPI Master.
In this case, the maximum clock is about 390KHz.

Update the Kernel first. This module drivers are available on 3.14.29-32 or higher.


odroid@odroid64:~$ sudo modprobe spi-bitbang
odroid@odroid64:~$ sudo modprobe spi-gpio
odroid@odroid64:~$ sudo modprobe spidev
odroid@odroid64:~$ lsmod

Compile & run SPI test example source code

odroid@odroid64:~$ gcc -o dot_test dot_test.c
odroid@odroid64:~$ sudo ./dot_test
spi mode: 0
bits per word: 8
max speed: 500000 Hz (500 KHz)

Set to 500 KHz, but it is actually operating at 390KHz.
