Slack client for Commodore 64

_Where a Raspberry Pi and a Commodore64 collaborate with Slack._

Commodore 64 program

The c64 program code is written in 6502 assembly and somewhat(?!) well documented.

Compiling

cd c64
acme main.asm

This will create build/slack-client.prg.

Running the program on real hardware

If you are reading this, have a C64, and plan to run this program on it, you likely don't need step-by-step instructions ;). Obviously it will need to copied onto a floppy disk, disk emulator etc.

LOAD "SLACK-CLIENT.PRG",<device_nbr>
RUN

Running with the Vice64 emulator

First, we need to configure the emulated serial port.

Open 'Settings' > 'Resource Inspector' window

Peripherals > Cartridges > Userport RS232 > 
  Baud Rate: 1200, 
  Enabled: true, 
  Device: device4
RS232 > Device4 > 
  Device: |../raspberry_pi/app.js, 
  Baud Rate: 1200

Hit 'Save current settings', then Quit.

cd c64
/path/to/x64 build/slack-client.prg

Raspberry Pi Slack API proxy

This is a NodeJS app which connects to the Slack RTM api on one side, and a serial port connection to the C64 on the other side and translates data back and forth.

It can be configured to communicate via a real serial port, or via stdout/stdin (for Vice64 emulator)

Configuration

First, you need to create a Slack OAuth token here https://api.slack.com/docs/oauth-test-tokens

export SLACK_API_TOKEN=token

If C64_SLACK_SERIALPORT_DEVICE is not defined, it will use stdout/stdin for communication. To communicate via a real serial port:

export C64_SLACK_SERIALPORT_DEVICE=/dev/ttyUSB0 (or /dev/cu.usbserial etc)

Run the API proxy:

cd raspberry_pi
npm install
npm test
node app.js

On startup, it will authenticate with Slack RTM api, then send a HELLO RPC message to the C64, which we expect to already be running.
