Simple Device Driver for Raspberry Pi 3 (Raspbian)

Description

When you insmod this driver, myled0 and myswitch0 will appear in /dev.

/dev/myled0 drives led connected to GPIO25
/dev/myswitch0 gets status connected to GPIO20

Requirements

• linux kernel source
  • download kernel source into /usr/src/linux
  • kernel build scripts : https://github.com/ryuichiueda/raspberry_pi_kernel_build_scripts
• Raspberry Pi 2 or Raspberry Pi 3
  • tested only on Raspberry Pi 3
• led
• resistor
  • 330[ohm]
  • 10k[ohm]
• switch

Installation

Hardware

Connect led, resistors, switch to Raspberry Pi as shown in schematic.
