hd108.h File Reference

Detailed Description

HD108 SPI chipset encoder.

Free function encoder for HD108 chipsets. HD108 uses 16-bit RGB with gamma correction and brightness control.

Protocol:

• Start frame: 64 bits (8 bytes) of 0x00
• LED data: [Header:2B][R:16b][G:16b][B:16b] (8 bytes per LED)
• End frame: (num_leds / 2) + 4 bytes of 0xFF

Header encoding (per-channel gain control):

• Byte 0: [1][RRRRR][GG] - marker bit, 5-bit R gain, 2 MSBs of G gain
• Byte 1: [GGG][BBBBB] - 3 LSBs of G gain, 5-bit B gain
• Currently: R=G=B=brightness (same gain for all channels)
• Future: Per channel gain control for higher color range
