infraout - BASIC Commands

Name:

infraout

Syntax:

INFRAOUT device,data

device - is a constant/variable (valid device ID 1-31)

data - is a constant/variable (valid data 0-127)

Description:

This command is deprecated, please consider using the irout command instead.

Transmit an infra-red signal, modulated at 40kHz. This command is used to transmit the infra-red data to Sony ™ device (can also be used to transmit data to another PICAXE that is using the infrain or infrain2 command). Data is transmitted via an infra-red LED (connected on output 0) using the SIRC (Sony Infra Red Control) protocol.

	device	5 bit device ID (0-31)
	data	7 bit data (0-127)

When using this command to transmit data to another PICAXE the device ID used must be value 1 (TV). The infraout command can be used to transmit any of the valid TV command 0-127. Note that the Sony protocol only uses 7 bits for data, and so data of value 128 to 255 is not valid. Therefore the valid infraout command for use with infrain2 is:

infraout 1,x

'(where x = 0 to 127)

Sony SIRC protocol

The SIRC protocol uses a 40KHz modulated infra-red signal consisting of a start bit (2.4ms) followed by 12 data bits (7 data bits and 5 device ID bits). Logic level 1 is transmitted as a 1.2 ms pulse, logic 0 as a 0.6ms pulse. Each bit is separated by a 0.6ms silence period. Interaction between infrain, infrain2 and infraout command.

Infrain and Infraout

The original infrain command was designed to react to signals from the TV style remote control TVR010. Therefore it only acknowledges the data sent from the 17 buttons on this remote (1-9, 0. 10+, P+, P-, V+, V-, MUTE, PWR) with a value between 1 and 17. The infraout command can be used to 'emulate' the TVR010 remote to transit signals that will be acceptable for the infrain command. The values to be used for each TV remote button are shown in the table.

Infrain2 and Infraout

The infrain2 command will react to any of the valid TV data commands (0 to 127). The infraout command can be used to transmit any of the valid TV command 0-127. Note that the Sony protocol only uses 7 bits for data, and so data of 128 to 255 is not valid. Therefore the valid infraout command for use with infrain2 is (where x = 0 to 127)

Effect of Increased Clock Speed:

This command will only function at 4MHz.
