Tufty 2350 Documentation

I’m finding this very difficult, slow and more than a bit frustrating. I would really like a basic, normal MicroPython .uf2 to use as an alternative on this super hardware. I hate not being able to do a screen.update() when I want to. I can fly a PRESTO but I feel like a total idiot on this TUFTY2350.

I just cannot see why this code just skips over title screen and goes straight to the middle/ main section but does the exit section. It worked before I added the exit screen part.

# Load some fonts
nope_font = rom_font.nope
compass_font = rom_font.compass
sins_font = rom_font.sins
ignore_font = rom_font.ignore
bacteria_font = rom_font.bacteria

count = 50
title_screen = True   # Flag for title screen
exit_screen = False   # Flag for exit screen
start_time = io.ticks

def update():         # This is the main loop
    global title_screen
    global exit_screen
    global count
    global start_time
        
    # Title screen   -  used for the first 2 seconds
    if title_screen:
        screen.pen = color.black
        screen.clear()
        screen.pen = color.red
        screen.font = bacteria_font
        screen.text("Testing",30,60)               
        if io.ticks - start_time >= 2000:
            title_screen = False

    # Exit screen - used for last 2 second after Button_B pressed
    if exit_screen:
        screen.pen = color.black
        screen.clear()               
        screen.pen = color.blue
        screen.font = bacteria_font
        screen.text("Good Bye",30,60)               
        if io.ticks - start_time >= 2000:
            exit_screen = False
            machine.reset()

    # The main loop  - used after the first 2 seconds
    else:
        screen.pen = color.blue
        screen.clear()

        screen.pen = color.yellow
        screen.font = nope_font
        screen.text("MAIN LOOP", 5, 5)
        
        screen.font = ignore_font
        screen.text(str(count), 70,50)
        
        screen.pen = color.white
        screen.font = sins_font
        screen.text(str(count), 140,5)
        
        # Draw bar graph
        screen.pen = color.green
        rectangle = shape.rectangle(25, 90, count, 20)
        screen.shape(rectangle)
        
        # Check U and D buttons
        if io.BUTTON_UP in io.pressed:
            count = count + 10
            if count > 100:
                count = 100
        if io.BUTTON_DOWN in io.pressed:
            count = count - 10
            if count < 0:
                count = 0
        if io.BUTTON_B in io.pressed:
            start_time = io.ticks
            exit_screen = True

I gave up with CircuitPython because it refused to support simple graphics but went ‘all layers and sprites’. I enjoy using PicoGraphics and can do quite complicated things like clocks.

I’m sure the majority of customers would appreciate a ‘normal’ .uf2 - perhaps add access to these rather nice and simple to use fonts.
