Remove the custom MotorController class and use the upstream MotorController instead. To enable this move add custom code in nrf_gpio to handle the Motor pin instead of the custom motor_is_running member variable. Also implement the repeating app_timer type used in the upstream MotorController.

*
|
|
* @brief Application timer functionality.
|
|
*
|
|
* @details This module enables the application to create multiple timer instances based on the RTC1
|
|
* peripheral. Checking for time-outs and invocation of user time-out handlers is performed
|
|
* in the RTC1 interrupt handler. List handling is done using a software interrupt (SWI0).
|
|
* Both interrupt handlers are running in APP_LOW priority level.
|
|
*
|
|
* @details When calling app_timer_start() or app_timer_stop(), the timer operation is just queued,
|
|
* and the software interrupt is triggered. The actual timer start/stop operation is
|
|
* executed by the SWI0 interrupt handler. Since the SWI0 interrupt is running in APP_LOW,
|
|
* if the application code calling the timer function is running in APP_LOW or APP_HIGH,
|
|
* the timer operation will not be performed until the application handler has returned.
|
|
* This will be the case, for example, when stopping a timer from a time-out handler when not using
|
|
* the scheduler.
|
|
*
|
|
* @details Use the USE_SCHEDULER parameter of the APP_TIMER_INIT() macro to select if the
|
|
* @ref app_scheduler should be used or not. Even if the scheduler is
|
|
* not used, app_timer.h will include app_scheduler.h, so when
|
|
* compiling, app_scheduler.h must be available in one of the compiler include paths.
