* 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
