I am driving my LEDs with a PMOS transistor, so they are active low now. Does this tool support this inversion? What I can do to invert the whole output...

Yeah, I made new hardware (active low) that was not with me at that time. It is different than my original setup which was active high. I was trying to...

So, this is my first test. **(1) My routine to turn all of them on white. Nothing happens.** It turns LEDs (the single led that was on) off, when running...

Ok, so I was testing jgarff/rpi_ws281x repo, and it didn't work too. After I bypassed my level-shifter/inverter using the active high code it worked. So, my hardware is good and...

I started to see light and colors when I changed this PWM initialization. They are not reproducing the pattern yet, but now I can see something working which is pretty...

Yeah, that pull-down in front of the Q1 is not good. The code is working and inverting just fine. Thanks for your help @tom-2015

I am seeing the `main.c` and I found this: ``` printf ("Opening %s as named pipe.", named_pipe_file); ``` The file is being created but the `printf` is not being executed....

Actually the error is here: ```c input_file = fopen(named_pipe_file, "r"); ```

I made it work by recreating the FIFO every time. I don't know if it is right thing to do, but it worked by now. ``` while (exit_program==0) { if...

Oh, sure, maybe that is the problem. Look, this is my system.  I just replaced this ``` case MODE_NAMED_PIPE: remove(DEFAULT_DEVICE_FILE); mkfifo(DEFAULT_DEVICE_FILE, 0777); chmod(DEFAULT_DEVICE_FILE, 0777); input_file = fopen(DEFAULT_DEVICE_FILE, "r"); break;...
