sli / partial.hy
Created July 19, 2016 22:39
Figuring out Lisp by implementing partials in hy.
(defn partial [f arg &rest args1]
(defn p [&rest args2]
(apply f (+ (list* arg (list args1)) (list args2)))))
(defn add [a &rest b]
(+ a (reduce + b)))
(def add10 (partial add 10))
(print (add10 15 20))

Read from an ADC channel on a Raspberry Pi. Shamelessly lifted from Adafruit.
import RPi.GPIO as GPIO
def readadc(adcnum, clockpin=18, mosipin=23, misopin=24, cspin=25):
if adcnum > 7 or adcnum < 0:
return -1
GPIO.output(cspin, True)
GPIO.output(clockpin, False) # start clock low
GPIO.output(cspin, False) # bring CS low

Sensor Network notes

sensed

  • First generation of the protocol, uses SocketIO and JSON for communication
  • sensed listens for data requests and responds accordingly
  • This method allows for managing of network resources and requesting data from specific sensors
  • senselog client round-robin requests data from each connected node, inserting the data into a Mongo database
  • senselog is a client reference implementation, sensed doesn't care about the client's purpose

lidard

  • Second generation of the protocol, uses UDP and msgpack for communication
  • msgpack is JSON-like, but is a binary format and results in much smaller packets
