Returns the callback configuration as set by SetInputValueCallbackConfiguration.

func (*IO16V2Bricklet) GetMonoflop Uses

func (device *IO16V2Bricklet) GetMonoflop(channel uint8) (value bool, time uint32, timeRemaining uint32, err error)

Returns (for the given channel) the current value and the time as set by SetMonoflop as well as the remaining time until the value flips.

If the timer is not running currently, the remaining time will be returned as 0.

func (*IO16V2Bricklet) GetResponseExpected Uses

func (device *IO16V2Bricklet) GetResponseExpected(functionID Function) (bool, error)

Returns the response expected flag for the function specified by the function ID parameter. It is true if the function is expected to send a response, false otherwise.

For getter functions this is enabled by default and cannot be disabled, because those functions will always send a response. For callback configuration functions it is enabled by default too, but can be disabled by SetResponseExpected. For setter functions it is disabled by default and can be enabled.

Enabling the response expected flag for a setter function allows to detect timeouts and other error conditions calls of this setter as well. The device will then send a response for this purpose. If this flag is disabled for a setter function then no response is send and errors are silently ignored, because they cannot be detected.

See SetResponseExpected for the list of function ID constants available for this function.

func (*IO16V2Bricklet) GetSPITFPErrorCount Uses

func (device *IO16V2Bricklet) GetSPITFPErrorCount() (errorCountAckChecksum uint32, errorCountMessageChecksum uint32, errorCountFrame uint32, errorCountOverflow uint32, err error)

Returns the error count for the communication between Brick and Bricklet.

The errors are divided into

* ACK checksum errors, * message checksum errors, * framing errors and * overflow errors.

The errors counts are for errors that occur on the Bricklet side. All Bricks have a similar function that returns the errors on the Brick side.

func (*IO16V2Bricklet) GetStatusLEDConfig Uses

func (device *IO16V2Bricklet) GetStatusLEDConfig() (config StatusLEDConfig, err error)

Returns the configuration as set by SetStatusLEDConfig

func (*IO16V2Bricklet) ReadUID Uses

func (device *IO16V2Bricklet) ReadUID() (uid uint32, err error)

Returns the current UID as an integer. Encode as Base58 to get the usual string version.

func (*IO16V2Bricklet) RegisterAllInputValueCallback Uses

func (device *IO16V2Bricklet) RegisterAllInputValueCallback(fn func([16]bool, [16]bool)) uint64

This callback is triggered periodically according to the configuration set by SetAllInputValueCallbackConfiguration.

The parameters are the same as GetValue. Additional the `changed` parameter is true if the value has changed since the last callback.

func (*IO16V2Bricklet) RegisterInputValueCallback Uses

func (device *IO16V2Bricklet) RegisterInputValueCallback(fn func(uint8, bool, bool)) uint64

This callback is triggered periodically according to the configuration set by SetInputValueCallbackConfiguration.

The parameters are the channel, a value-changed indicator and the actual value for the channel. The `changed` parameter is true if the value has changed since the last callback.

func (*IO16V2Bricklet) RegisterMonoflopDoneCallback Uses

func (device *IO16V2Bricklet) RegisterMonoflopDoneCallback(fn func(uint8, bool)) uint64

This callback is triggered whenever a monoflop timer reaches 0. The parameters contain the channel and the current value of the channel (the value after the monoflop).

func (*IO16V2Bricklet) Reset Uses

func (device *IO16V2Bricklet) Reset() (err error)

Calling this function will reset the Bricklet. All configurations will be lost.

After a reset you have to create new device objects, calling functions on the existing ones will result in undefined behavior!

func (*IO16V2Bricklet) SetAllInputValueCallbackConfiguration Uses

func (device *IO16V2Bricklet) SetAllInputValueCallbackConfiguration(period uint32, valueHasToChange bool) (err error)

The period in ms is the period with which the RegisterAllInputValueCallback callback is triggered periodically. A value of 0 turns the callback off.

If the `value has to change`-parameter is set to true, the callback is only triggered after the value has changed. If the value didn't change within the period, the callback is triggered immediately on change.

If it is set to false, the callback is continuously triggered with the period, independent of the value.

The default value is (0, false).

func (*IO16V2Bricklet) SetBootloaderMode Uses

func (device *IO16V2Bricklet) SetBootloaderMode(mode BootloaderMode) (status BootloaderStatus, err error)

Sets the bootloader mode and returns the status after the requested mode change was instigated.

You can change from bootloader mode to firmware mode and vice versa. A change from bootloader mode to firmware mode will only take place if the entry function, device identifier and CRC are present and correct.

This function is used by Brick Viewer during flashing. It should not be necessary to call it in a normal user program.

Associated constants:

* BootloaderModeBootloader
* BootloaderModeFirmware
* BootloaderModeBootloaderWaitForReboot
* BootloaderModeFirmwareWaitForReboot
* BootloaderModeFirmwareWaitForEraseAndReboot
* BootloaderStatusOK
* BootloaderStatusInvalidMode
* BootloaderStatusNoChange
* BootloaderStatusEntryFunctionNotPresent
* BootloaderStatusDeviceIdentifierIncorrect
* BootloaderStatusCRCMismatch

func (*IO16V2Bricklet) SetConfiguration Uses

func (device *IO16V2Bricklet) SetConfiguration(channel uint8, direction Direction, value bool) (err error)

Configures the value and direction of a specific channel. Possible directions are 'i' and 'o' for input and output.

If the direction is configured as output, the value is either high or low (set as *true* or *false*).

If the direction is configured as input, the value is either pull-up or default (set as *true* or *false*).

For example:

* (0, 'i', true) will set channel-0 as input pull-up. * (1, 'i', false) will set channel-1 as input default (floating if nothing is connected). * (2, 'o', true) will set channel-2 as output high. * (3, 'o', false) will set channel-3 as output low.

A running monoflop timer for the specific channel will be aborted if this function is called.

The default configuration is input with pull-up.

Associated constants:

* DirectionIn
* DirectionOut

func (*IO16V2Bricklet) SetEdgeCountConfiguration Uses

func (device *IO16V2Bricklet) SetEdgeCountConfiguration(channel uint8, edgeType EdgeType, debounce uint8) (err error)

Configures the edge counter for a specific channel.

The edge type parameter configures if rising edges, falling edges or both are counted if the channel is configured for input. Possible edge types are:

* 0 = rising (default) * 1 = falling * 2 = both

The debounce time is given in ms.

Configuring an edge counter resets its value to 0.

If you don't know what any of this means, just leave it at default. The default configuration is very likely OK for you.

Default values: 0 (edge type) and 100ms (debounce time)

Associated constants:

* EdgeTypeRising
* EdgeTypeFalling
* EdgeTypeBoth

func (*IO16V2Bricklet) SetInputValueCallbackConfiguration Uses

func (device *IO16V2Bricklet) SetInputValueCallbackConfiguration(channel uint8, period uint32, valueHasToChange bool) (err error)

This callback can be configured per channel.

The period in ms is the period with which the RegisterInputValueCallback callback is triggered periodically. A value of 0 turns the callback off.

If the `value has to change`-parameter is set to true, the callback is only triggered after the value has changed. If the value didn't change within the period, the callback is triggered immediately on change.

If it is set to false, the callback is continuously triggered with the period, independent of the value.

The default value is (0, false).

func (*IO16V2Bricklet) SetMonoflop Uses

func (device *IO16V2Bricklet) SetMonoflop(channel uint8, value bool, time uint32) (err error)

Configures a monoflop of the specified channel.

The second parameter is the desired value of the specified channel. A *true* means relay closed and a *false* means relay open.

The third parameter indicates the time (in ms) that the channels should hold the value.

If this function is called with the parameters (0, 1, 1500) channel 0 will close and in 1.5s channel 0 will open again

A monoflop can be used as a fail-safe mechanism. For example: Lets assume you have a RS485 bus and a IO-16 Bricklet 2.0 connected to one of the slave stacks. You can now call this function every second, with a time parameter of two seconds and channel 0 closed. Channel 0 will be closed all the time. If now the RS485 connection is lost, then channel 0 will be opened in at most two seconds.

func (*IO16V2Bricklet) SetResponseExpected Uses

func (device *IO16V2Bricklet) SetResponseExpected(functionID Function, responseExpected bool) error

Changes the response expected flag of the function specified by the function ID parameter. This flag can only be changed for setter (default value: false) and callback configuration functions (default value: true). For getter functions it is always enabled.

Enabling the response expected flag for a setter function allows to detect timeouts and other error conditions calls of this setter as well. The device will then send a response for this purpose. If this flag is disabled for a setter function then no response is send and errors are silently ignored, because they cannot be detected.

func (*IO16V2Bricklet) SetResponseExpectedAll Uses

func (device *IO16V2Bricklet) SetResponseExpectedAll(responseExpected bool)

Changes the response expected flag for all setter and callback configuration functions of this device at once.

func (*IO16V2Bricklet) SetSelectedValue Uses

func (device *IO16V2Bricklet) SetSelectedValue(channel uint8, value bool) (err error)

Sets the output value of a specific channel without affecting the other channels.

A running monoflop timer for the specific channel will be aborted if this function is called.

Note

This function does nothing for channels that are configured as input. Pull-up
resistors can be switched on with SetConfiguration.

func (*IO16V2Bricklet) SetStatusLEDConfig Uses

func (device *IO16V2Bricklet) SetStatusLEDConfig(config StatusLEDConfig) (err error)

Sets the status LED configuration. By default the LED shows communication traffic between Brick and Bricklet, it flickers once for every 10 received data packets.

You can also turn the LED permanently on/off or show a heartbeat.

If the Bricklet is in bootloader mode, the LED is will show heartbeat by default.

Associated constants:

* StatusLEDConfigOff
* StatusLEDConfigOn
* StatusLEDConfigShowHeartbeat
* StatusLEDConfigShowStatus

func (*IO16V2Bricklet) SetValue Uses

func (device *IO16V2Bricklet) SetValue(value [16]bool) (err error)

Sets the output value of all sixteen channels. A value of *true* or *false* outputs logic 1 or logic 0 respectively on the corresponding channel.

Use SetSelectedValue to change only one output channel state.

For example: (True, True, False, False, ..., False) will turn the channels 0-1 high and the channels 2-15 low.

All running monoflop timers will be aborted if this function is called.

Note

This function does nothing for channels that are configured as input. Pull-up
resistors can be switched on with SetConfiguration.

func (*IO16V2Bricklet) SetWriteFirmwarePointer Uses

func (device *IO16V2Bricklet) SetWriteFirmwarePointer(pointer uint32) (err error)

Sets the firmware pointer for WriteFirmware. The pointer has to be increased by chunks of size 64. The data is written to flash every 4 chunks (which equals to one page of size 256).

This function is used by Brick Viewer during flashing. It should not be necessary to call it in a normal user program.

func (*IO16V2Bricklet) WriteFirmware Uses

func (device *IO16V2Bricklet) WriteFirmware(data [64]uint8) (status uint8, err error)

Writes 64 Bytes of firmware at the position as written by SetWriteFirmwarePointer before. The firmware is written to flash every 4 chunks.

You can only write firmware in bootloader mode.

This function is used by Brick Viewer during flashing. It should not be necessary to call it in a normal user program.

func (*IO16V2Bricklet) WriteUID Uses

func (device *IO16V2Bricklet) WriteUID(uid uint32) (err error)

Writes a new UID into flash. If you want to set a new UID you have to decode the Base58 encoded UID string into an integer first.

We recommend that you use Brick Viewer to change the UID.

type StatusLEDConfig Uses

type StatusLEDConfig uint8
const (
    StatusLEDConfigOff           StatusLEDConfig = 0
    StatusLEDConfigOn            StatusLEDConfig = 1
    StatusLEDConfigShowHeartbeat StatusLEDConfig = 2
    StatusLEDConfigShowStatus    StatusLEDConfig = 3
)
