A nicer way to view the output from a GridEye in the terminal. Useful for headless debugging.

fake_camera.py

import random
import math
import time

low = 19.0
high = 25.0


def randInRange():
    spread = high - low
    return (random.random() * spread) + low


def make_a_fake_grid(x=8, y=8):
    outer = []
    for i in range(x):
        outer.append([randInRange() for _ in range(y)])
    return outer


def displayChar(value, low=low, high=high, px_width=2):
    # img_chars = "$@B%8&WM#*oahkbdpqwmZO0QLCJUYXzcvunxrjft/\|()1[]?-_+~<>i!lI;:,^`'. "
    # img_chars = " .:;+=xX$&"
    img_chars = " ░▒▓█"

    spread = high - low
    transformedValue = value - low
    pc = transformedValue / spread
    i = math.floor(pc * len(img_chars))
    return img_chars[i] * px_width


while True:
    grid = make_a_fake_grid()
    for row in grid:
        print("".join([displayChar(v) for v in row]))
    print()
    time.sleep(1)

Produces something like this:

░░▓▓  ░░▓▓░░░░░░
▓▓░░░░▒▒  ░░  ░░
▓▓▓▓  ░░▓▓  ██░░
██░░██████▓▓██▒▒
  ██▓▓▓▓▓▓░░████
▓▓  ░░▒▒██░░  ██
  ░░  ░░  ▓▓▒▒▓▓
▓▓▒▒██▒▒▒▒▓▓▓▓░░

But it looks better in a real terminal.
