The extension board has 12DI/12DO/2AI/2AO, see User Manual for interface details.

Set Digital Output auto_sync

Sets digital output (extension board).

• Function: set_extra_do from the lua module
• Parameters:
  1. pin: [int] Port, starting from 0
  2. value: [int] Value to set, 0 off / 1 on
• Returns: [bool] Whether set successfully

Example

set_extra_do(1, 1)

Get Digital Input

Gets digital input (extension board).

• Function: get_extra_di from the lua module
• Parameters:
  1. pin: [int] Port, starting from 0
• Returns: [int] Port current value, 0 off / 1 on

Example

print(get_extra_di(1))

Wait Digital Input auto_sync

Blocks and waits until the specified port input value meets the specified condition.

• Function: wait_extra_di from the lua module
• Parameters:
  1. pin: [int] Port, starting from 0
  2. value: [int] Value to compare, 0 off / 1 on
  3. relation: [str] Relational Operator
