FPulse is LED pulsing application.

The specification of pulse sequence for each LED is defined in a configuration file. FPulse reads configuration file and changes brightness of LEDs according to the configured specification.

Tested on Raspberry Pi with TLC5947. To run it on Raspberry Pi use provided Systemd service file or run it manually, i.e.::

$ fpulse tlc5947 morse.conf

For testing purposes, one can run FPulse on any computer with the following command::

$ fpulse print morse.conf

Sample configuration files are in conf directory.

TLC5947 Driver

TLC5947 driver was tested with Adafruit 24-Channel 12-bit PWM LED Driver having SPI interface

http://www.adafruit.com/products/1429

The connection schematics is presented in the documentation of the driver

fpulse/driver/tlc5947.py

The TLC5947 driver requires bcm2835 shared library, which can be downloaded from::

http://www.airspayce.com/mikem/bcm2835/

To build the library::

$ cd bcm2835-{VER}
$ ./configure CFLAGS=-fPIC
$ make
$ cd src
$ gcc -shared bcm2835.o -o libbcm2835.so -fPIC

Install the bcm2835 shared library in appropriate directory or set LD_LIBRARY_PATH environment variable appropriately.
