Raspberry Pi from MacOS via SD Card

• get the image: https://www.raspberrypi.org/software/operating-systems/
• install the image: https://www.raspberrypi.org/documentation/installation/installing-images/mac.md
• diskutil list to find out the rdisk that your SD is associated with
• diskutil unmountDisk /dev/diskN replacing the rdiskN with the number of the disk your SD card is associated with
• sudo dd bs=1m if=path_of_your_image.img of=/dev/rdiskN; sync replacing the rdiskN with the number of the disk your SD card is associated with. In my case this is sudo dd bs=1m if=/Users/andrew/Downloads/2021-03-04-raspios-buster-armhf-lite.img of=/dev/rdisk3; sync (you can see the progress by pressing ctrl+t)
• this will put the image on /Volumes/boot which will be accessible from the command line
• sudo diskutil eject /dev/rdiskN to eject the SD card.

Set up Wifi on the card

• https://www.raspberrypi.org/documentation/configuration/wireless/headless.md

• cd /Volumes/boot

• vim wpa_suplicant.conf

• enter wifi and country code in the file but that note that this will need to be the 2.4GHz network if you have a Raspberry Pi that does not support 5GHz.

  ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
  update_config=1
  country=GB<Insert 2 letter ISO 3166-1 country code here>
  
  network={
  ssid="<Name of your wireless LAN>"
  psk="<Password for your wireless LAN>"
  }
  

• enable ssh https://www.raspberrypi.org/documentation/remote-access/ssh/README.md easiest is to place a ssh file in the sd card during setup

• eject the SD card and put in the raspberry pi and turn it on

Format the SD Card

• sudo diskutil eraseDisk FAT32 RASPBIAN MBRFormat /dev/diskN replacing diskN with your disk number found by running diskutil list. Note that this gives the name RASBIAN to the SD Card so now you can cd into /Volumes/RASPBIAN. I followed this site: https://www.michaelcrump.net/the-magical-command-to-get-sdcard-formatted-for-fat32/

Install Nodejs on the raspberry pi

• Need to SSH into the PI first then you can do the command line work.
• Follow this as it worked for me: https://www.instructables.com/Install-Nodejs-and-Npm-on-Raspberry-Pi/
• wget https://nodejs.org/dist/v14.16.1/node-v14.16.1-linux-armv7l.tar.gz
• tar -xzf node-v14.16.1-linux-armv7l.tar.gz
• cd node-v14.16.1-linux-armv7l/
• sudo cp -R * /usr/local/
• Check if node is installed node -v
• Check if npm is installed npm -v

Install Apache

• https://www.raspberrypi.org/documentation/remote-access/web-server/apache.md
• Should be able to navigate to http://raspberrypi.lan/
• Files should be kept in /var/www/html/ directory
• Folder and file permissions for the var/www folder : https://www.raspberrypi.org/forums/viewtopic.php?t=155067

Johnny Five Button on Pi

• npm install johnny-five raspi-io
• create index.js
• =======

Install Dependencies

• sudo apt install vim nginx git
• install rustup: curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
• install openssl and direnv: sudo apt install openssl direnv
• cargo build --release
• install more deps sudo apt install libprotobuf-dev protobuf-compiler
• try again cargo build --release

Install the 64 bit version of the Raspberry Pi OS

• https://illegalexception.schlichtherle.de/raspbian/2019/09/21/how-to-upgrade-raspbian-to-a-64-bit-kernel/

Run Next with pm2

• https://trinitytuts.com/tips/deploying-a-nextjs-app-in-production-with-pm2/
• Create the build first npm run build
• pm2 start npm --name "Next App" -- start
• Save pm2 settings pm2 save
• With nginx make sure the correct permissions: sudo chown -R pi:www-data /var/www

Code to run the button on raspberry pi with johnny-five

const five = require('johnny-five');
const Raspi = require('raspi-io').RaspiIO;
const board = new five.Board({
	io: new Raspi(),
});

board.on('ready', function () {
	const button1 = new five.Button('P1-7');

	button1.on('press', async () => {
		console.log('button1 pressed');
	});
});

• Needs to be run with sudo privileges e.g. sudo node index.js
