Inkplate 6 MicroPython - Draw Image from WiFi

Inkplate 6 can connect to WiFi and fetch images directly from the internet. This example demonstrates downloading a JPEG file from a URL and rendering it on e-paper display.

Downloading and displaying an image

Below is a complere example that connects to WiFi and loads an image from the web. Make sure to replace the SSID and password with your own WiFi credentials.

import network
import time
from inkplate6 import Inkplate

SSID = "ENTER_SSID_HERE"
PASSWORD = "ENTER_PASSWORD_HERE"

def do_connect():
    sta_if = network.WLAN(network.STA_IF)
    if not sta_if.isconnected():
        print("Connecting to network...")
        sta_if.active(True)
        sta_if.connect(SSID, PASSWORD)

        timeout = 30
        start = time.ticks_ms()
        while not sta_if.isconnected():
            if time.ticks_diff(time.ticks_ms(), start) > timeout * 1000:
                print("Failed to connect within timeout")
                return False
            time.sleep(0.5)
    print("Network config:", sta_if.ifconfig())
    return True

# Create Inkplate in 2-bit grayscale mode
inkplate = Inkplate(Inkplate.INKPLATE_2BIT)
inkplate.begin()

if not do_connect():
    raise SystemExit("WiFi connection failed")

inkplate.drawImage(
    "https://i.imgur.com/6vMuKxa.jpeg",
    0, 0,
    invert=False,
    dither=True,
    kernel_type=Inkplate.KERNEL_FLOYD_STEINBERG
)

inkplate.display()

inkplate.drawImage()

Download and draw an image from a URL or local file path onto the display buffer.

Function parameters:

Type	Name	Description
String	path	Image URL or local file path.
Number	x	X coordinate of top-left corner where image will be placed.
Number	y	Y coordinate of top-left corner where image will be placed.
Boolean	invert	If True, invert black and white colors.
Boolean	dither	Enable or disable dithering for grayscale images.
Constant	kernel_type	Dithering algorithm to use (e.g., Inkplate.KERNEL_FLOYD_STEINBERG).

ℹ️

Available options for dithering algorithm:

Algorithm	Value
Inkplate.KERNEL_FLOYD_STEINBERG	0
Inkplate.KERNEL_JJN	1
Inkplate.KERNEL_STUCKI	2
Inkplate.KERNEL_BURKES	3

Performance Notes

• JPG: ~3 seconds (or ~14s with dithering)
• PNG: ~9 seconds (or ~19s with dithering)
• BMP: ~20 seconds (or ~40s with dithering)
• Maximum image file size: ~800kB
