- | ===== Paper-Duino-Hat ===== | ||
- | {{:raspberry_boards:paper-duino-hat_212250.jpg?400|}}\\ | ||
- | This is the latest version of the [[raspberry_boards:paperduinopi|Paper-Duino-Pi]]. It is an Arduino Hat for the Raspberry Pi.\\ | ||
- | It has an Reset-Button (GPIO 22) and a GPIO LED (GPIO 27) on the board. The Serial connection is made over the serial GPIO pins, plus GPIO 18 for the Reset.\\ | ||
- | It works on the Raspberry Pi B+, 2 and 3.\\ | ||

- | ==== Installing the Arduino IDE ==== | ||
- | based on the code from: | ||
- | https://github.com/mharizanov/avrdude-rpi | ||
- | |||
- | Before starting make an update: | ||
- | $ sudo apt-get update | ||
- | $ sudo apt-get upgrade | ||
- | Install the Arduino IDE: | ||
- | $ sudo apt-get install arduino | ||
- | In: | ||
- | $ sudo raspi-config | ||
- | Enable "shell and kernel messages on the serial connection" in Advanced Options/Serial.\\ | ||
- | Make a new folder: | ||
- | $ mkdir paper-duino-pi | ||
- | $ cd paper-duino-pi | ||
- | Download the files: | ||
- | $ wget http://dernulleffekt.de/programme/paperduinopi_v05/paper-duino-hat_01.tar.gz | ||
- | And unpack: | ||
- | $ tar -xvf paper-duino-hat_01.tar.gz | ||
- | Run the setup: | ||
- | $ sudo chmod 755 setup | ||
- | $ sudo ./setup | ||
- | Test the Serial connection: | ||
- | $ ls -lh /dev | ||
- | It should look like that: | ||
- | crw-rw-rw- 1 root dialout 204, 64 Jul 10 20:24 ttyAMA0 | ||
- | lrwxrwxrwx 1 root root 7 Jul 10 20:08 ttyS0 -> ttyAMA0 | ||
- | Start the arduino IDE. | ||
- | $ arduino | ||
- | Upload your code with Arduino-Uno on the port: ttyS0. | ||
- | |||
- | ---- | ||
- | |||
- | ==== Install the Shutdown Button and the LED ==== | ||
- | |||
- | Go to your Paper-Duino-Pi folder | ||
- | $ cd /home/pi/paper-duino-pi | ||
- | Download the Python script: | ||
- | $ wget http://www.dernulleffekt.de/programme/paperduinopi_v05/shutdown_and_blink_01.tar.gz | ||
- | And unpack it: | ||
- | $ tar xf shutdown_and_blink_01.tar.gz | ||
- | Change owner & rights | ||
- | $ sudo chown root:root shutdownbutton_hat.py blink_hat.py | ||
- | $ sudo chmod 755 shutdownbutton_hat.py blink_hat.py | ||
- | Create the autostart: | ||
- | $ sudo nano /etc/rc.local | ||
- | Write before "exit 0": | ||
- | printf " \n" | ||
- | printf " =============================================\n" | ||
- | printf " = PAPER-DUINO-HAT =\n" | ||
- | printf " = =\n" | ||
- | printf " = wolfgang spahn 07-2016 =\n" | ||
- | printf " = http://dernulleffekt.de =\n" | ||
- | printf " =============================================\n" | ||
- | printf " \n" | ||
- | # run reset and shutdown script | ||
- | printf "Starts shutdown aund reset button on GPIO 22\n" | ||
- | /home/pi/paper-duino-pi/shutdownbutton_hat.py & | ||
- | # blink an LED | ||
- | printf "Starts blinking LED on GPIO 27\n" | ||
- | /home/pi/paper-duino-pi/blink_hat.py & | ||
- | To save and leave press: CTRL+O, Enter, CTRL+X\\ | ||
- | Reboot: | ||
- | $ sudo reboot | ||
- | |||
- | ---- | ||
- | ==== Burning the Boatloader ==== | ||
- | To burn the Boatloader on the Atmega328p chip on has to wire up the Raspberry Pi and the Paper-Duino-Pi like that:\\ | ||
- | {{:raspberry_boards:spi-connection_202802.jpg?400|}}\\ | ||
- | |||
- | Raspberry Pi | Paper-Duino-Hat | ||
- | ====================================== | ||
- | MOSI (GPIO 10) | MOSI (pin 11) | ||
- | MISO (GPIO 9) | MISO (pin 12) | ||
- | SCLK (GPIO 11) | SCK (pin 13) | ||
- | RST (GPIO 25) | Reset | ||
- | GND | GND | ||
- | 3.3V | 5V | ||
- | |||
- | Run on the following commands:\\ | ||
- | Run the configuration menue:\\ | ||
- | $ sudo raspi-config | ||
- | Enable SPI in Advanced Options/SPI, if necessary reboot the Pi.\\ | ||
- | Now there should be an SPI device in /dev: spidev0.0 and/or spidev0.1. | ||
- | $ ls /dev | ||
- | Go to: | ||
- | $ cd /usr/share/arduino/hardware/arduino/bootloaders/optiboot | ||
- | Erase the chip (some chips need that): | ||
- | $ sudo avrdude -p m328p -c linuxspi -P /dev/spidev0.0 -e -F | ||
- | Burn the Bootloader:\\ | ||
- | $ sudo avrdude -p m328p -c linuxspi -P /dev/spidev0.0 -U flash:w:optiboot_atmega328.hex:i | ||
