Description
With the example slightly modified to work with the Adafruit FeatherWing OLED screen, I see the progress bar progression across the screen slow down as the percentage increases. Any pointers on how to troubleshoot this?
Here is a video: https://youtu.be/B2AHjPbJh7c
And the code:
import time
import board
import displayio
import terminalio
from adafruit_bitmap_font import bitmap_font
from adafruit_display_text import label
import adafruit_displayio_ssd1306
from adafruit_progressbar import ProgressBar
displayio.release_displays()
i2c = board.I2C()
display_bus = displayio.I2CDisplay(i2c, device_address=0x3C)
display = adafruit_displayio_ssd1306.SSD1306(display_bus, width=128, height=32)
splash = displayio.Group(max_size=10)
display.show(splash)
color_bitmap = displayio.Bitmap(128, 32, 1)
color_palette = displayio.Palette(1)
color_palette[0] = 0x0
bg_sprite = displayio.TileGrid(color_bitmap, x=0, y=0, pixel_shader=color_palette)
splash.append(bg_sprite)
progress_bar = ProgressBar(0, 0, 128, 32, 1.0)
splash.append(progress_bar)
textbox_bitmap = displayio.Bitmap(80,20,1)
textbox_palette = displayio.Palette(1)
textbox_palette[0] = 0x000000 #Black
textbox_sprite = displayio.TileGrid(textbox_bitmap, pixel_shader=textbox_palette,x=25, y=5)
splash.append(textbox_sprite)
text = "Fuel Pumping!"
text_area = label.Label(terminalio.FONT, text=text, color=0xFFFFFF, x=27, y=14)
splash.append(text_area)
current_progress = 0.0
while True:
while current_progress <= 1.0:
print("Progress: {}%".format(current_progress * 100))
progress_bar.progress = current_progress
current_progress += 0.01
if current_progress >= 1.0:
current_progress = 0.0
time.sleep(0.01)
