# MicroPython TM1640 LED Matrix
A MicroPython library for a LED matrix modules using the TM1740 LED driver.
## Installation
Using mip via mpremote:
```bash
$ mpremote mip install github:mcauser/micropython-tm1640
```
Using mip directly on a WiFi capable board:
```python
>>> import mip
>>> mip.install("github:mcauser/micropython-tm1640")
```
Manual installation:
Copy `tm1640.py` to the root directory of your device.
## Examples
**Basic usage**
```python
import tm1640
from machine import Pin
tm = tm1640.TM1640(clk=Pin(14), dio=Pin(13))
# line from bottom left to top right
tm.write([1, 2, 4, 8, 16, 32, 64, 128])
# all on
tm.write([255, 255, 255, 255, 255, 255, 255, 255])
# all off
tm.write([0, 0, 0, 0, 0, 0, 0, 0])
# all LEDs dim
tm.brightness(1)
# all LEDs bright
tm.brightness(7)
# the number 3
tm.write([0b00000000, 0b00011110, 0b00110011, 0b00110000, 0b00011100, 0b00110000, 0b00110011, 0b00011110])
# cross
tm.write(b'\x81\x42\x24\x18\x18\x24\x42\x81')
# squares
tm.write([255, 129, 189, 165, 165, 189, 129, 255])
# 50% on
tm.write_int(0x55aa55aa55aa55aa)
```
