getting started with the spark core 1

hardware • 72MHz ARM Cortex M3 • TI CC3000 WiFi
• 7 analog IO (pwm out), 7 digital IO • ~ S$ 55 • coming soon: Photon, 120MHz, Broadcom Wifi, half the price 3
setup, the easy and unreliable way • install smartphone app
• power up spark • use smartphone app to create cloud account and register the core 4
setup, the better way (USB) npm install spark-cli spark setup
5
ready? • your spark core should have a name and
be breathing cyan by now 6
the tinker firmware • default firmware of spark core •
allows access to all inputs/outputs 7
let’s ask the cloud export SPARK_CORE_ID=53ff71065075535128311587 export SPARK_ACCESS_TOKEN=[get this from
https://spark.io/ build or “spark login”] 8
let’s ask the cloud curl -H "Authorization: Bearer $SPARK_ACCESS_TOKEN” https://
api.spark.io/v1/devices/$SPARK_CORE_ID/ Alternatively include the token in the URL: https://api.spark.io/v1/devices/$SPARK_CORE_ID/?access_token= $SPARK_ACCESS_TOKEN 9
output { "id": "53ff71065075535128311587", "name": "schnitzel", "connected": true, "variables": {},
"functions": [ "digitalread", "digitalwrite", "analogread", "analogwrite" ], "cc3000_patch_version": "1.29" 10
using functions curl https://api.spark.io/v1/devices/$SPARK_CORE_ID/ digitalwrite?access_token=$SPARK_ACCESS_TOKEN -d params=D7,LOW or include access_token
in POST data: curl https://api.spark.io/v1/devices/$SPARK_CORE_ID/ digitalwrite -d access_token=$SPARK_ACCESS_TOKEN -d params=D7,LOW 11
response { "id": "53ff71065075535128311587", "name": "schnitzel", "last_app": null, "connected": true,
"return_value": 1 } 12
the cloud API • events, functions, variables • http://docs.spark.io/api/ 13
the javascript API • runs in browser and in nodejs
• (npm|bower) install spark • http://docs.spark.io/javascript/ 14
voodoospark • alternative firmware • faster communication through local TCP
connection • npm client module • still uses cloud for facilitating local connection 15
