Tiva C driver for APA102C LEDs

apa102c - Tiva C series driver for APA102C Super LED IC's

This repository contains the software driver for controling APA102C LED driver IC's using Tiva C series hardware.

The driver was tested using a Tiva C EK-TM4C123GXL development board.

Getting started:

Using this driver is simple:

1. Add apa102c_conf.h, apa102c.h and apa102c.c to your project
2. Edit apa102c_conf.h and set the SPI peripheral you intend to use and the number of LED's in the strip.
3. Import apa102c.h

After that:

• Use clear_strip() to clear the strip data (this only clears the internal representation of the LED states).
• Use set_pixel() and clear_pixel() to manipulate individual pixel values.
• Use display_strip() to send the internal pixel data to the strip.

TODOs:

• Use interrupts
• Use uDMA
• Use CMSIS instead of the TivaWare library
• Add functions to allow creation of effects by manipulating the internal representation.
