Thread Programming and Device driver in Zephyr RTOS
-----------------------------------------------------------------------------------------------------------------------------------------
Following project is used to develop an application to develop a distance sensor channel for HC-SR04 and an I2C-based EEPROM device driver Zephyr RTOS (version 1.10.0) on Galileo Gen 2 board.
Getting Started :
These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.
See deployment for notes on how to deploy the project on a live system.
Prerequisites :
zephyr 1.10.0 source code
zephyr sdk 0.9.2
CMake version 3.8.2 or higher is required
HC-SR04 distance sensor
Microchip 24FC256 CMOS EEPROM
Installing :
Unzip & download below files in user directory on your machine running linux distribution.
1) README.md
2) sensor (directory)
3) Report_4
4) flash(directory)
5) HCSR_app(directory)
Deployment :
Install zephyr source code with patched version & sdk.
Create the following directories
efi
efi/boot
kernel
Locate binary at $ZEPHYR_BASE/boards/x86/galileo/support/grub/bin/grub.efi and copy it to $SDCARD/efi/boot
Rename grub.efi to bootia32.efi
Create a $SDCARD/efi/boot/grub.cfg file wich contains following :
set default=0
set timeout=10
menuentry "Zephyr Kernel" {
multiboot /kernel/zephyr.strip
}
Make following connections of GPIO :
IO1 => Trigger pin for HC-SR04 distance sensor 1
IO2 => Echo pin for HC-SR04 distance sensor 1
IO3 => Trigger pin for HC-SR04 distance sensor 2
IO4 => Echo pin for HC-SR04 distance sensor 2
IO18 => SDA pin for Microchip 24FC256 CMOS EEPROM
IO19 => SCL pin for Microchip 24FC256 CMOS EEPROM
IO0 => Write-protection pin for Microchip 24FC256 CMOS EEPROM
A0, A1, A2 set to ground.
Execution :
From sensor directory, copy and replace contents in /zephyr/drivers/sensor directory
From flash directory, copy and replace contents in /zephyr/drivers/flash directory
Copy HCSR_app in /zephyr/samples directory
Change directory to following :
cd $ZEPHYR_BASE/samples/HCSR_app/build
Use cmake command as below :
cmake -DBOARD=galileo ..
Make using following :
make
Locate zephyr.strip file generated in $ZEPHYR_BASE/samples/HCSR_app/build/zephyr
Copy this to $SDCARD/kernel
Insert SD card in Galileo board and reboot.
-----------------------------------------------------------------------------------------------
Expected results :
On execution program asks user to enter command in shell prompt.
Select respective shell module e.g.
select shell_mod
1] To enable particular sensor,use enable command with suitable n value.
n can take {0-None, 1-HCSR0, 2-HCSR1}
shell_mod> enable n
2] To write p pages of EEPROM, use start command with suitable p
where p can take number between {1 to 512}.
For example with "start 10" command, it will write 10 pages to EEPROM.
shell_mod> start p
3] To read pages of EEPROM, use dump command with suitable p1 & p2 that defines range of pages to be read.
p1 & p2 can take number between {1 to 512} & p1 < p2
For example with "dump 2 5" command, it will read page 2 to 5 from EEPROM.
shell_mod> dump p1 p2
