/**
|
||
|
* @brief CAN TALON SRX driver.
|
||
|
*
|
||
|
* The TALON SRX is designed to instrument all runtime signals periodically.
|
||
|
* The default periods are chosen to support 16 TALONs with 10ms update rate
|
||
|
* for control (throttle or setpoint). However these can be overridden with
|
||
|
* SetStatusFrameRate. @see SetStatusFrameRate
|
||
|
* The getters for these unsolicited signals are auto generated at the bottom
|
||
|
* of this module.
|
||
|
*
|
||
|
* Likewise most control signals are sent periodically using the fire-and-forget
|
||
|
* CAN API. The setters for these unsolicited signals are auto generated at the
|
||
|
* bottom of this module.
|
||
|
*
|
||
|
* Signals that are not available in an unsolicited fashion are the Close Loop
|
||
|
* gains. For teams that have a single profile for their TALON close loop they
|
||
|
* can use either the webpage to configure their TALONs once or set the PIDF,
|
||
|
* Izone, CloseLoopRampRate, etc... once in the robot application. These
|
||
|
* parameters are saved to flash so once they are loaded in the TALON, they
|
||
|
* will persist through power cycles and mode changes.
|
||
|
*
|
||
|
* For teams that have one or two profiles to switch between, they can use the
|
||
|
* same strategy since there are two slots to choose from and the
|
||
|
* ProfileSlotSelect is periodically sent in the 10 ms control frame.
|
||
|
*
|
||
|
* For teams that require changing gains frequently, they can use the soliciting
|
||
|
* API to get and set those parameters. Most likely they will only need to set
|
||
|
* them in a periodic fashion as a function of what motion the application is
|
||
|
* attempting. If this API is used, be mindful of the CAN utilization reported
|
||
|
* in the driver station.
|
||
|
*
|
||
|
* If calling application has used the config routines to configure the
|
||
|
* selected feedback sensor, then all positions are measured in floating point
|
||
|
* precision rotations. All sensor velocities are specified in floating point
|
||
|
* precision RPM.
|
||
|
* @see ConfigPotentiometerTurns
|
||
|
* @see ConfigEncoderCodesPerRev
|
||
|
* HOWEVER, if calling application has not called the config routine for
|
||
|
* selected feedback sensor, then all getters/setters for position/velocity use
|
||
|
* the native engineering units of the Talon SRX firm (just like in 2015).
|
||
|
* Signals explained below.
|
||
|
*
|
||
|
* Encoder position is measured in encoder edges. Every edge is counted
|
||
|
* (similar to roboRIO 4X mode). Analog position is 10 bits, meaning 1024
|
||
|
* ticks per rotation (0V => 3.3V). Use SetFeedbackDeviceSelect to select
|
||
|
* which sensor type you need. Once you do that you can use GetSensorPosition()
|
||
|
* and GetSensorVelocity(). These signals are updated on CANBus every 20ms (by
|
||
|
* default). If a relative sensor is selected, you can zero (or change the
|
||
|
* current value) using SetSensorPosition.
|
||
|
*
|
||
|
* Analog Input and quadrature position (and velocity) are also explicitly
|
||
|
* reported in GetEncPosition, GetEncVel, GetAnalogInWithOv, GetAnalogInVel.
|
||
|
* These signals are available all the time, regardless of what sensor is
|
||
|
* selected at a rate of 100ms. This allows easy instrumentation for "in the
|
||
|
* pits" checking of all sensors regardless of modeselect. The 100ms rate is
|
||
|
* overridable for teams who want to acquire sensor data for processing, not
|
||
|
* just instrumentation. Or just select the sensor using
|
||
|
* SetFeedbackDeviceSelect to get it at 20ms.
|
||
|
*
|
||
|
* Velocity is in position ticks / 100ms.
|
||
|
*
|
||
|
* All output units are in respect to duty cycle (throttle) which is -1023(full
|
||
|
* reverse) to +1023 (full forward). This includes demand (which specifies
|
||
|
* duty cycle when in duty cycle mode) and rampRamp, which is in throttle units
|
||
|
* per 10ms (if nonzero).
|
||
|
*
|
||
|
* Pos and velocity close loops are calc'd as
|
||
|
* err = target - posOrVel.
|
||
|
* iErr += err;
|
||
|
* if( (IZone!=0) and abs(err) > IZone)
|
||
|
* ClearIaccum()
|
||
|
* output = P X err + I X iErr + D X dErr + F X target
|
||
|
* dErr = err - lastErr
|
||
|
* P, I, and D gains are always positive. F can be negative.
|
||
|
* Motor direction can be reversed using SetRevMotDuringCloseLoopEn if
|
||
|
* sensor and motor are out of phase. Similarly feedback sensor can also be
|
||
|
* reversed (multiplied by -1) if you prefer the sensor to be inverted.
|
||
|
*
|
||
|
* P gain is specified in throttle per error tick. For example, a value of 102
|
||
|
* is ~9.9% (which is 102/1023) throttle per 1 ADC unit(10bit) or 1 quadrature
|
||
|
* encoder edge depending on selected sensor.
|
||
|
*
|
||
|
* I gain is specified in throttle per integrated error. For example, a value
|
||
|
* of 10 equates to ~0.99% (which is 10/1023) for each accumulated ADC unit
|
||
|
* (10 bit) or 1 quadrature encoder edge depending on selected sensor.
|
||
|
* Close loop and integral accumulator runs every 1ms.
|
||
|
*
|
||
|
* D gain is specified in throttle per derivative error. For example a value of
|
||
|
* 102 equates to ~9.9% (which is 102/1023) per change of 1 unit (ADC or
|
||
|
* encoder) per ms.
|
||
|
*
|
||
|
* I Zone is specified in the same units as sensor position (ADC units or
|
||
|
* quadrature edges). If pos/vel error is outside of this value, the
|
||
|
* integrated error will auto-clear...
|
||
|
* if( (IZone!=0) and abs(err) > IZone)
|
||
|
* ClearIaccum()
|
||
|
* ...this is very useful in preventing integral windup and is highly
|
||
|
* recommended if using full PID to keep stability low.
|
||
|
*
|
||
|
* CloseLoopRampRate is in throttle units per 1ms. Set to zero to disable
|
||
|
* ramping. Works the same as RampThrottle but only is in effect when a close
|
||
|
* loop mode and profile slot is selected.
