Coding Project | Pico Desktop Clock

A fun project using a Raspberry Pi Pico microcontroller. Out of my comfort zone of web development where I have virtually limitless RAM and a 1000 screen sizes to deal with. Here I have around 100kb of RAM and a round screen at 240 x 240 pixels.

Considering the display at 8 bit will consume another 50kb of RAM, there isn't much left

	def drawHand(value, distance, intervals = 60):
	    """Draw a hand on the clock face
	    value: The hand position
	    distance: The distance from the centre
	    intervals: The number of intervals"""

	    display.set_pen(GREEN)

	    # Calculate the position of the hand
	    angle = math.pi * 2 * (value / intervals) - math.pi / 2
	    x = int(MIDX + math.cos(angle) * distance)
	    y = int(MIDY + math.sin(angle) * distance)

	    # Draw the hand
	    display.line(MIDX, MIDY, x, y)
