Introduction

This documentation includes content that details the functions that make up the TV Control Proxy which is supported in the DriverWorks Software Development Kit.

Proxies (Commands)

A proxy driver is an interface to the Control4 system for a set of devices that share common functionality. For instance, most TVs have common controls such as ON, OFF and MUTE.  The TV Control Proxy allows for a common user interface to control all TVs.  The Control4 system (Director) sends information to and receives information from the proxy drivers.  The proxy drivers send information to and receives information from the protocol drivers. Remember, your DriverWorks driver interacts with the proxy driver which then interacts with the system.  As a driver developer you will be relying on this proxy to provide status (notification) to the Control4 system for the device you are controlling.  You will also receive commands from the system that you will act on to control the device.  These commands and notifications are at the heart of what you will be implementing in your driver.  Essentially your driver is becoming the go-between from the Control4 system and your device with the proxy driver giving structure to the commands and notifications which you will be implementing. Your driver can facilitate communications with multiple types of proxies for a single device. As an example, a Security System driver will utilize both the Security proxy and the Contacts proxy. These additional proxies are configured in the <connections> section of the .c4z.

Protocol (Notifications)

Two similar devices may have the same functionality but utilize a very different command set.  A protocol driver provides the device-specific information needed to communicate with the Control4 system.  In the case of DriverWorks, the DriverWorks driver is the protocol driver.  When combined with the device-specific.c4Z file it provides the custom code necessary to implement the 2-way device driver. In the case of DriverWorks, the DriverWorks driver is the protocol driver. When combined with the device-specific.c4Z file it provides the custom code necessary to implement the 2-way device driver.

Example

The example to the right detail the table of information that is received from the proxy when a channel is selected:

FM:
ReceivedFromProxy:      SET_CHANNEL
BindingID               5002
CHANNEL                 96.3
INPUT                   3028
OUTPUT                  0

AM:
ReceivedFromProxy:      SET_CHANNEL
INPUT                   3027
BindingID               5002
CHANNEL                 1100
INPUT                   3027
OUTPUT                  0

In the FM example, channel 96.3 has been selected in the tuner protocol. The 96.3 value is passed into the data table as a string. It is important to note that if the bandwidth type (AM, FM) is not provided (and the proxy in question is not TV) a manner in which to identify the bandwidth type will need to be developed. An example of this code follows:

  if tParams['BANDTYPE'] == nil then
   if (string.find(tParams['CHANNEL'],"%p") ~= nil) then
    tParams['BANDTYPE'] = 'FM'
    local ChannelLen = string.len(tParams['CHANNEL'] )
    local ChannelFix = string.sub(tParams['CHANNEL'],1,ChannelLen-2) ..
    string.sub(tParams['CHANNEL'],ChannelLen-1,ChannelLen-1)
    tParams ['CHANNEL'] = ChannelFix
   else
    tParams['BANDTYPE'] = 'AM'
end end
end

CHANNEL_CHANGED

Name

CHANNEL_CHANGED ()

Returns

None

Usage Note

If the BANDTYPE is not supplied, as in older drivers, the INPUT binding # will be used to determine which band the tuner is on. All DriverWorks drivers need to use the BANDTYPE parameter if they want the band to propagate up to Navigator to display the channel properly. If the DriverWorks driver does not know the current channel and the “has_feedback” capability is not set to “True”, none of this matters and everything will keep working as it previously has. A CHANNEL_CHANGED must be issued immediately after the INPUT_CHANGED in order for the UI to update. See the example to the right.

C4:SendToproxy(5002,'INPUT_CHANGED',
{INPUT=3009,BANDTYPE='FMBand',MINCHANNEL=8750,
MAXCHANNEL=10790,CHANNELSPACING=20})
C4:SendToProxy(5002,'CHANNEL_CHANGED',{CHANNEL=10290})

Note that in the example, 5002 is the ProxyBindingID for the Tuner. INPUT 3009 is the ID for the FM Antenna on the 5002 Tuner. Navigator determines AM/FM/XM with the following rule:

• ID 3000 and 3001 are AM
• ID 3002 and 3003 are FM

Audio Output Bindings and Proxy Events

Note: Audio Output binding ID values defined in drivers written in conjunction with this Proxy must start with a binding value of 4000. The acceptable range for Audio Outputs is 4000 - 4999. However, if the first output binding ID value is not 4000, issues with Proxy Events firing correctly can be encountered.

For a list of valid Binding ID values please see the Connections section of the DriverWorks Fundamentals Guide.
