# TLC5940 Micropython Library

![tlc5940](img/chip.jpg)

Minimal implementation of grey scale data transmission with multiple tlc5940 in series.

```python

import tlc5940

tlc = tlc5940.interface('GP23', 'GP1', 'GP7', 'GP2', 'GP14', 'GP16')

data = tlc5940.simple_byte_array("1010000000000000")

tlc.set_data(data) # enable output0 and output2

```

Includes example code for driving multiple 7-segments displays.
