Dio commands sender.

The diocmd driver keeps on repeating configured dio interface command.

Compile-time dependencies

• none

Provides

• dio

Requires

• (optional) dio (if configured, commands will be sent there)

Configuration requests

• none

Configuration file options

• bits (string)
  • Default: "00000000000000000000000000000000"
  • Initial state (number of bits is significant)
  • Last character is the lowest bit (length greater than 0, max. 32 characters)
• read_only (integer)
  • Default: 1
  • If set to 1, received commands will not change the state
• wait_on_normal (double)
  • Default: 0.0 (no effect)
  • Wait time in secs.
• wait_on_opposite (double)
  • Default: 0.0 (no effect)
  • Wait time in secs.
• sleep_nsec (integer)
  • Default: 100000000 (10 sends per second)
  • timespec value for nanosleep()

When wait_on_normal and wait_on_opposite options are given, this driver acts as a clock signal source.

Example

(
  name "diocmd"
  provides ["dio:100"]
