impl<'a> Driver for LTC294XDriver<'a>

fn subscribe(&self, subscribe_num: usize, callback: Callback) -> ReturnCode

Setup callbacks.

subscribe_num

• 0: Set the callback that that is triggered when events finish and when readings are ready. The first argument represents which callback was triggered.
  • 0: Interrupt occurred from the LTC294X.
  • 1: Got the status.
  • 2: Read the charge used.
  • 3: done() was called.
  • 4: Read the voltage.
  • 5: Read the current.

fn command(
    &self,
    command_num: usize,
    data: usize,
    _: usize,
    _: AppId
) -> ReturnCode

Request operations for the LTC294X chip.

command_num

• 0: Driver check.
• 1: Get status of the chip.
• 2: Configure settings of the chip.
• 3: Reset accumulated charge measurement to zero.
• 4: Set the upper threshold for charge.
• 5: Set the lower threshold for charge.
• 6: Get the current charge accumulated.
• 7: Shutdown the chip.
• 8: Get the voltage reading. Only supported on the LTC2942 and LTC2943.
• 9: Get the current reading. Only supported on the LTC2943.
• 10: Set the model of the LTC294X actually being used. data is the value of the X.

fn allow(
    &self,
    app: AppId,
    minor_num: usize,
    slice: AppSlice<Shared, u8>
) -> ReturnCode

allow lets an application give the driver access to a buffer in the application's memory. This returns ENOSUPPORT if not used.
