Send a data packet using RFOUT

This program will send a data packet of incrementing byte variables every second to an RF transmitter module connected to output pin B.1.

Code Example:

main:	inc b0						; Increment the base value
	b1 = b0 + 1					; Set other variables from the base value
	b2 = b0 + 2
	b3 = b0 + 3
	b4 = b0 + 4
	b5 = b0 + 5
	b6 = b0 + 6
	b7 = b0 + 7
	rfout B.1, ( b0, b1, b2, b3, b4, b5, b6, b7 )	; Send the data packet
	pause 1000					; Wait 1 second
	goto main					; Send next data

Send a data packet via an NKM2401

This program will send a data packet of incrementing byte variables every second to an NKM2401 module connected to output pin B.1 with an RF transmitter module connected.

Code Example:

main:	inc b0							; Increment the base value
	b1 = b0 + 1						; Set other variables from the base value
	b2 = b0 + 2
	b3 = b0 + 3
	b4 = b0 + 4
	b5 = b0 + 5
	b6 = b0 + 6
	b7 = b0 + 7
	serout B.1, n2400, ( b0, b1, b2, b3, b4, b5, b6, b7 )	; Send the data packet
	pause 1000						; Wait 1 second
	goto main

Send a data packet directly to an RF module

This program will send a data packet of incrementing byte variables every second to an RF transmitter module connected to output pin B.1.

Code Example:

main:	inc b0							; Increment the base value
	b1 = b0 + 1						; Set other variables from the base value
	b2 = b0 + 2
	b3 = b0 + 3
	b4 = b0 + 4
	b5 = b0 + 5
	b6 = b0 + 6
	b7 = b0 + 7
	serout B.1, t2400, ( "UUUUUUUUUUUUUUUUUUUUUUUUUUUU" )	; Send a preamble
	pause 10						; Allow receiver to synchronise
	serout B.1, t2400, ( "XYZZY" )				; Send a data qualifier
	serout B.1, t2400, ( b0, b1, b2, b3, b4, b5, b6, b7 )	; Send the data packet
	pause 1000						; Wait 1 second
	goto main
