# This file contains common pin mappings for Duet2 Eth/Wifi boards
# that have the Duex expansion board. To use this config, the firmware
# should be compiled for the SAM4E8E.

# See the example.cfg file for a description of available parameters.

## Drivers
# Here are the pins for the 10 stepper drivers supported by a Duet2 board
# | Drive |  DIR pin |  STEP pin |  ENDSTOP pin |  SPI EN pin |
# |-------|----------|-----------|--------------|-------------|
# | X     |  PD11    |  PD6      |  PC14        |  PD14       |
# | Y     |  PD12    |  PD7      |  PA2         |  PC9        |
# | Z     |  PD13    |  PD8      |  PD29        |  PC10       |
# | E0    |  PA1     |  PD5      |  PD10        |  PC17       |
# | E1    |  PD9     |  PD4      |  PC16        |  PC25       |
# | E2    |  PD28    |  PD2      |  PE0*        |  PD23       |
# | E3    |  PD22    |  PD1      |  PE1*        |  PD24       |
# | E4    |  PD16    |  PD0      |  PE2*        |  PD25       |
# | E5    |  PD17    |  PD3      |  PE3*        |  PD26       |
# | E6    |  PA25    |  PD21     |  PA17*       |  PC28       |
# Pins marked with asterisks (*) are only assigned to these functions
# if no duex is connected. If a duex is connected, these endstops are
# remapped to the SX1509 on the Duex (unfortunately they can't be used
# as endstops in klipper, however one may use them as digital outs or
# PWM outs). The SPI EN pins are required for the TMC2660 drivers (use
# the SPI EN pin as 'cs_pin' in the respective config block). The
# **enable pin for all steppers** is TMC_EN = !PC6.
#
## Fans
# | FAN  |          PIN          |
# |------|-----------------------|
# | FAN0 |  PC23                 |
# | FAN1 |  PC26                 |
# | FAN2 |  PA0                  |
# | FAN3 |  sx1509_duex:PIN_12*  |
# | FAN4 |  sx1509_duex:PIN_7*   |
# | FAN5 |  sx1509_duex:PIN_6*   |
# | FAN6 |  sx1509_duex:PIN_5*   |
# | FAN7 |  sx1509_duex:PIN_4*   |
# | FAN8 |  sx1509_duex:PIN_15*  |
# Pins marked with (*) assume the following sx1509 config section:
#[sx1509 duex]
#i2c_address: 62
#
## Heaters and Thermistors
# | Extruder Drive |  HEAT pin |  TEMP pin |
# |----------------|-----------|-----------|
# | BED            |  PA19     |  PC13     |
# | E0             |  PA20     |  PC15     |
# | E1             |  PA16     |  PC12     |
# | E2             |  PC3      |  PC29     |
# | E3             |  PC5      |  PC30     |
# | E4             |  PC8      |  PC31     |
# | E5             |  PC11     |  PC27     |
# | E6             |  PA15     |  PA18     |
