+ | ===== Accessing Output Signals Directly ===== | ||
+ | A peripheral output block delivers a signal to external hardware. Its signal value can be accessed with a get method, see line 41 in the comment in the example code in [[https:// | ||
+ | |||
+ | Alternatively the signal in the HAL could be accessed by getting an reference to the corresponding output block with | ||
+ | <code cpp> | ||
+ | auto digOut = hal.getLogicOutput(" | ||
+ | </ | ||
+ | The signal value can then be logged with | ||
+ | block with | ||
+ | <code cpp> | ||
+ | log.info() << digOut-> | ||
+ | </ | ||
+ | You have to make sure to access the output with non-exclusive rights, because the control system already has a handle to it, see line 25 in '' |
