OLED Screen for Android 16: Tutorial

General
1

I got the Pironman 5 OLED working on Android 16 using Termux with a Python system monitor (CPU, RAM, Disk bars).

Install Termux from the play store or aptoid

!Some commands may or may not need to be ran as sudo!

SETUP:

pkg update -y
pkg upgrade -y

pkg install -y python
pkg install -y clang
pkg install -y libjpeg-turbo
pkg install -y libpng
pkg install -y zlib

pip install pillow
pip install luma.oled
pip install psutil

CREATE SCRIPT:

sudo nano /data/data/com.termux/files/home/oled_test.py

PASTE THIS: use all of it to where it ends at the line of asterisks*

import psutil

import time

from luma.oled.device import ssd1306

from luma.core.interface.serial import i2c

from PIL import Image, ImageDraw, ImageFont

# OLED setup

serial = i2c(port=1, address=0x3C)

device = ssd1306(serial)

# Display layout

WIDTH = 128

HEIGHT = 64

BAR_X = 72

BAR_WIDTH = 50

BAR_HEIGHT = 8

font = ImageFont.load_default()

last_values = None

# Prime CPU reading

psutil.cpu_percent(interval=None)

# Get CPU temperature

def get_cpu_temp():

try:

    with open("/sys/devices/virtual/thermal/thermal_zone0/temp", "r") as f:

        temp = int(f.read()) / 1000.0

        return temp

except:

    return 0.0

# Draw bar function

def draw_bar(draw, label, value, y, display_value=None, unit=“%”):

percent = max(0, min(int(value), 100))

filled = int((percent / 100) \* BAR_WIDTH)

filled = max(filled, 1)

\# Text display

if display_value is None:

    text = f"{label} {percent}{unit}"

else:

    text = f"{label} {display_value}{unit}"

draw.text((0, y), text, font=font, fill=255)

\# Bar outline

draw.rectangle((BAR_X, y, BAR_X + BAR_WIDTH, y + BAR_HEIGHT), outline=255, fill=0)

\# Bar fill

right_edge = max(BAR_X + filled - 1, BAR_X + 1)

draw.rectangle((BAR_X + 1, y + 1, right_edge, y + BAR_HEIGHT - 1), fill=255)

# Main loop

while True:

cpu = int(psutil.cpu_percent(interval=None))

ram = int(psutil.virtual_memory().percent)

disk = int(psutil.disk_usage('/storage/emulated/0').percent)

\# Temperature

temp_c = get_cpu_temp()

THROTTLE_TEMP = 80

temp_percent = int(max(0, min((temp_c / THROTTLE_TEMP) \* 100, 100)))

values = (cpu, ram, disk, temp_percent)

if values != last_values:

    image = Image.new("1", (WIDTH, HEIGHT), 0)

    draw = ImageDraw.Draw(image)

    draw_bar(draw, "CPU", cpu, 2)

    draw_bar(draw, "RAM", ram, 18)

    draw_bar(draw, "DSK", disk, 34)

    draw_bar(draw, "TMP", temp_percent, 50, int(temp_c), "C")

    device.display(image)

    last_values = values

time.sleep(2)

**********************************************************************

RUN:

sudo python /data/data/com.termux/files/home/oled_test.py

AUTO START ON BOOT:

pkg install -y termux-api
mkdir -p ~/.termux/boot

sudo nano ~/.termux/boot/oled.sh

PASTE:

#!/data/data/com.termux/files/usr/bin/bash
sleep 10
sudo python /data/data/com.termux/files/home/oled_test.py

MAKE EXECUTABLE:

chmod +x ~/.termux/boot/oled.sh

NOTES:

  • Disk is using /storage/emulated/0

  • Temp is placeholder (0 for now)

  • sleep 10 helps prevent startup conflicts

  • I have found that if the OLED is flashing or acting weird after editing it the script for it, usually restarting android itself helps

  • Some commands may or may not need to be ran as sudo

  • My next project is to get the LED’s working

This is a generated pic of what it will look like, the temperature bar is from 0-80c and 100% represents thermal throttling.
