terminal

druid

a super-basic terminal and some utilities for crow

setup

• tested on linux & mac osx (attaches to first found crow port)
• requires python 2.7+
• requires pyserial. install using pip install pyserial
• optionally uses readline. install using pip install readline (mac / linux only)

druid (REPL)

python druid.py

• type q (enter) to quit.
• crow response is printed after each command entered.
• readline enabled (up arrow)
• type r to send & run the lua script in sketch.lua immediately
• type u to upload the script in sketch.lua to crow's internal flash memory
• type p to print the script currently in crow's internal flash memory

example:

10.0.0.132 ~/druid $ python druid.py
//// druid. q to quit.

> x=6

> print(x)
6

> output[1].volts = 0

> q

upload

python upload.py examples/test-2.lua

download

python download.py

prints to screen. copy to file by:

python download.py > feathers.lua

---

c version

check out the c subfolder

setup

run make

then run ./druid

q to quit

port

default connects to

/dev/ttyAMA0

specify an arg for different port ie

./druid /dev/ttyAMA1

BROKEN

• DOESN'T WORK ON MACOS. serial port open just hangs.
• sloppy use of getch() means chars aren't reported until CR, so there are double-prints etc
• crow prints will interrupt command typing
• no readline niceties (up-arrow)

TODO

• hack into old command-line maiden, use readline and ncurses etc
