# LED Panel Driver Module

![heavily compressed GIF image of P10 LED panel display.](./figure1.gif)

A Minimal MicroPython driver module for Panel P10 32*16 Matrix display and its variants, to handle 1/4 scanline and its unconventional byte data arrangements.

## Usage Example

```python

from framebuf import FrameBuffer, MONO_HLSB

from machine import Pin

from led_panel import LEDPanel

# Init

led = LEDPanel(

  pe = Pin(14, Pin.OUT),

  pa = Pin(13, Pin.OUT),

  pb = Pin(12, Pin.OUT),

  pclk = Pin(18, Pin.OUT),

  plat = Pin(19, Pin.OUT),

  pdr = Pin(23, Pin.OUT),

  freq = 1000,

  duty = 1

)

w = 32

h = 16

# FrameBuffer

ba = bytearray((w * h) // 8) # 1 bpp

fb = FrameBuffer(ba, w, h, MONO_HLSB)

# Main code

def main():

  x = 0

  while 1:

    fb.fill(0)

    fb.text("Hi,all!", x+w, 0, 1)

    fb.text("WOW!", 0, 9, 1)

    

    x = (x-1) % -96

    

    # Mandatory pause

    # Can be used as sleep

    await led.hold(50 / 1000) # msec

# Execute

# Must be last

led.run(ba, main)

```

The `hold()` function is a convenient utility for adding a mandatory asyncio pause without the need to import asyncio into the main code. It allows to add a pause in seconds, including float and fractions, or leave it empty for the shortest possible pause.
