"Hardware revision is not supported" For Raspberry Pi 4 Model B Rev 1.5

[marcuszerep]

The newest Raspberry Pis (at least from Canakit on Amazon) will fail in the https://github.com/jgarff/rpi_ws281x dependency until jgarff/rpi_ws281x#483 is resolved.

When the issue is resolved and solution is pushed there, looking forward to the https://www.npmjs.com/package/rpi-ws281x update.

See fork https://github.com/etcetc/rpi-ws281x which has the code with everything but 1gb (doesn't have most recent code changes from dependency)
https://github.com/etcetc/rpi-ws281x/blob/d393229554af04c71465a410dfa1896c7547e5d9/src/rpi_ws281x/rpihw.c#L139

However, the NPM script is not updated.

Thanks for opening this issue. I ran into the same problem and found, with some help, a workaround.

1. npm install rpi-ws281x

2. Update the file 'rpihw.c' (which is located in "node_modules - rpi-ws281x - src - rpi_ws281x"). I added:
   {
   .hwver= 0xd03115,
   .type= RPI_HWVER_TYPE_PI4,
   .periph_base= PERIPH_BASE_RPI4,
   .videocore_base= VIDEOCORE_BASE_RPI2,
   .desc= "Pi 4 Model B - 8GB v1.5"
   },

3. npm rebuild rpi-ws281x

After the rebuild, it works for me.
