Struct picoborgrev::PicoBorgRev [−][src]
The PicoBorgRev provides an easy way to interact with a PicoBorg Reverse
from rust. The communication is done via the embedded-hal i2c traits and
the PicoBorg Reverse is located at the i2c address 0x44 by default.
Methods
impl<T: Read + Write + WriteRead> PicoBorgRev<T>[src]
impl<T: Read + Write + WriteRead> PicoBorgRev<T>pub fn new(device: T) -> Result<PicoBorgRev<T>, <T as WriteRead>::Error>[src]
pub fn new(device: T) -> Result<PicoBorgRev<T>, <T as WriteRead>::Error>Attempt to create a new PicoBorgRev.
This will fail if either the i2c device has an error or the PicoBorg
Reverse is not found at the default address (0x44).

state: bool
) -> Result<(), <T as Write>::Error>Sets the system to enable or disable the communications failsafe. The failsafe will turn the motors off unless it is commanded at least once every 1/4 of a second.

pub fn get_drive_fault(&mut self) -> Result<bool, <T as WriteRead>::Error>[src]
pub fn get_drive_fault(&mut self) -> Result<bool, <T as WriteRead>::Error>Reads the system drive fault state, False for no problems, True for a fault has been detected. Faults may indicate power problems, such as under-voltage (not enough power), and may be cleared by setting a lower drive power.
If a fault is persistent, it repeatably occurs when trying to control the board, this may indicate a wiring problem such as:
- The supply is not powerful enough for the motors
- The board has a bare minimum requirement of 6V to operate correctly
- A recommended minimum supply of 7.2V should be sufficient for smaller motors
- The + and - connections for either motor are connected to each other
- Either + or - is connected to ground (Gnd, also known as 0V or earth)
- Either + or - is connected to the power supply (V+, directly to the battery or power pack)
- One of the motors may be damaged
Faults will self-clear, they do not need to be reset, however some faults require both motors to be moving at less than 100% to clear.
The easiest way to check is to put both motors at a low power setting which is high enough for them to rotate easily, such as 30%. Note that the fault state may be true at power up, this is normal and should clear when both motors have been driven.
If there are no faults but you cannot make your motors move check
get_epo to see if the safety switch has been tripped.

pub fn set_encoder_move_mode(
&mut self,

encoder move mode (enabled) the encoder_move_motor* commands are
available to move fixed distances. In non-encoder move mode
(disabled) the set_motor* commands should be used to set drive

The encoder move mode requires that the encoder feedback is attached to an encoder signal, see the website at www.piborg.org/picoborgrev for wiring instructions.
The encoder based move mode is disabled at power on.
