| - | A serialized design has been chosen to provide data to TLC. Prototype feature only 2 steps but the CORE works like there's 4 modules of 16 steps connected. In order to benchmark reactivity and Transfer time, Core send data for 4 modules. Through an emulated software SPI bus, for this 64 rings Data Sending __takes less than 5ms__ . Different colors and patterns like relative value(-64/63), keyboard(B&W keys) etc... were tested.\\ | + | A serialized design has been chosen to provide data to TLC.
