a960894d14 Another option for Ws2812 - direct spi from the pi with 1 wire (#631)
* Removed -HUP so the default -TERM signal is sent instead.
- hyperiond only listens for TERM and INT. HUP is often used to get an exe to reread its config

Changed pgrep to add '-x' so it wont partial match on the exe name.
- I have multiple instances with multiple hyperiond-instance1 names
- this ensures the service script only kills the right process

* reversing errant change to hyperion.systemd.sh

* This add a new device type - ws2812spi.

I've (ab)used the SPI interface to send the correct timing pulses to keep the ws2812 happy.
THE RATE IS IMPORTANT!
A FIXED CORE_CLK IS IMPORTANT!

Attach the SPI MOSI pin on the Pi to the DIN pin on your ws2812

        "device" :
        {
                "name"       : "MyPi",
                "type"       : "ws2812spi",
                "colorOrder" : "grb",
                "output"     : "/dev/spidev0.0",
                "rate"       : 3800000
        },

* updated hyperiond.test-binary

* Updated default SPI speed to the "correct" value.
My Pi was undervolted so was dropping the core clock confusing everything

* Code cleanups
explicitly set the final 3 bytes to 0

* Removed latchtime option - not applicable

* updated test binary

c17e4894d9 Apa102 fix if the led strip has more physical LEDs than you want to configure with hyperion (#626)
* Removed -HUP so the default -TERM signal is sent instead.
- hyperiond only listens for TERM and INT. HUP is often used to get an exe to reread its config

Changed pgrep to add '-x' so it wont partial match on the exe name.
- I have multiple instances with multiple hyperiond-instance1 names
- this ensures the service script only kills the right process

* reversing errant change to hyperion.systemd.sh

* started bug fixes for APA strips with more physical leds than configured

* 1st cut of changes to APA102.

now looks at config for "leds" which is the # of hardware leds in the strip.
This enables us to write the correct trailer length in the packet.

Also fixed a bug where switchoff was writing the wrong # of leds

* removed commented out old code

removed debug printf

* included prebuild test binary for Pi2

* Second attempt at the fix.
BEFORE:
If you have more physcial LEDs than defined in the "leds" "index" section of the config there is random junk added to the end of the strip.

WITH THIS FIX:
In the "device" section specify the number of physical leds with:
 "leds" : 212,
If this is greater than the number of led indexes, additional LEDs are set to black
If this is smaller than the number of led indexes, it is ignored

* included test binary

* Clean exit if the device config is missing or a non-supported device type is specified
