Detailed Description

16bit shift register (2x74595) interface

The pinout is hard coded as follows: 32u4 port Schematics SHR16_CLK: signal D13 - PC7 U8 -> U2 & U9 & P6 - SHCP (CLOCK) SHR16_LAT: signal D10 - PB6 U8 -> U2 & U9 & P6 - STCP (LATCH) SHR16_DAT: signal D9 - PB5 U8 -> U2 -> U9 -> P6 - DS/Q7S (DATA)

Shift register outputs: LEDS - hardcoded 74HC595 Schematics SHR16_LEDR0 = 0x0080 Q0.7 U2 -> D23 closest LED to Button S2 SHR16_LEDG0 = 0x0040 Q0.6 U2 -> D22 SHR16_LEDR1 = 0x8000 Q1.7 U9 -> D21 SHR16_LEDG1 = 0x4000 Q1.6 U9 -> D20 SHR16_LEDR2 = 0x2000 Q1.5 U9 -> D19 SHR16_LEDG2 = 0x1000 Q1.4 U9 -> D18 SHR16_LEDR3 = 0x0800 Q1.3 U9 -> D17 SHR16_LEDG3 = 0x0400 Q1.2 U9 -> D16 SHR16_LEDR4 = 0x0200 Q1.1 U9 -> D15 SHR16_LEDG4 = 0x0100 Q1.0 U9 -> D14 clostest LED to usb port J1 SHR16_LED_MSK = 0xffc0

TMC2130 Direction/Enable signals - hardcoded 74HC595 Schematics SHR16_DIR_0 = 0x0001 Q0.0 U2 -> U5 - DIR SHR16_ENA_0 = 0x0002 Q0.1 U2 -> U5 - DRV-ENN SHR16_DIR_1 = 0x0004 Q0.2 U2 -> U6 - DIR SHR16_ENA_1 = 0x0008 Q0.3 U2 -> U6 - DRV-ENN SHR16_DIR_2 = 0x0010 Q0.4 U2 -> U7 - DIR SHR16_ENA_2 = 0x0020 Q0.5 U2 -> U7 - DRV-ENN

SHR16_DIR_MSK = (SHR16_DIR_0 + SHR16_DIR_1 + SHR16_DIR_2) SHR16_ENA_MSK = (SHR16_ENA_0 + SHR16_ENA_1 + SHR16_ENA_2)
