Project - Simple UDP Control

The  Red, Green, Blue  LEDs of a Sonoff B1 Lamp or neopixels or a standard RGB LED can be controlled by broadcasting the individual R, G, B values OR a single 24bit combined RGB value using UDP .


At the bottom of the Annex Toolkit UDP Console tab are 3 sliders which broadcasts a 24bit combined RGB value to the subnet.
These sliders can be used as a UDP RGB lamp controller for the simple scripts below.
Don't let the relative simplicity fool you... running the same simple script on multiple devices offers impressive synchronized lighting control.

This first script is for a Sonoff B1 Lamp:                    view Sonoff B1 demo vid

Basic:

'Simple UDP Sonoff B1 Lamp Controller - developed on Annex 1.41 beta2 - Electroguard
sonoffb1.init
sonoffb1.rgb 0         'RGB leds OFF
udp.begin(5001)      'change port number if wished, but must match with Toolkit UDP Console port setting
onudp udpRX
wait

udpRX:
sonoffb1.rgb val(udp.read$)
return

'----------- End ------------


This next script is for a standard RGB LED. The module shown in  this demo video  is using gpio's 12,13,15 for its onboard RGB LED..
Using the 3 R,G,B sliders is pretty cool, but If you're into home automation then you'll probably love what's coming next...
Notice towards the end of the demo that the RGB LEDs can also be controlled simply by sending a value from the 'Message to Send' window.

Type &hff into the UDP Consoles 'Message to Send' window then click the 'Send all' button to turn on the blue led.
Type in 0 then click 'Send all' to turn it off.
Similarly send &h00ff for green, &hff0000 for red, &hffffff for white, and send 0 whenever you wish to turn all LEDs off.
Any Annex devices are capable of sending such UDP broadcasts, so it is very easy for Annex to control simple home-automation lighting.
Using different UDP ports on the same subnet allows having multiple independent lighting channels 

A noticeable difference from the previous script is that the incoming 24bit combined RGB value needs to be spilt into its 3 R,G,B component values to operate the appropriate PWM pins. Also, the 0 to 255 UDP slider values need multiplying by 4 to match the 0 to 1023 PWM range.,

Basic:

'Simple UDP RGB LED Controller - developed on Annex 1.41 beta2 - Electroguard
Rpin=12: Gpin=15: Bpin=13         'assign gpio pins to R,G,B leds
r=0: g=0: b=0                              'assign initial r,g,b values
gosub changeit                            'branch to set values
udp.begin(5001)   
onudp udpRX
wait

udpRX:
x=val(udp.read$)                          'read incoming 24bit combined RGB value
b=(x and &hff)                              'extract just the B value
g=(x >> 8) and &hff                      'extract just the G value
r=(x >> 16) and &hff                     'extract just the R value
gosub changeit
return

changeit:
pwm(Rpin)=r*4                             'multipy the 0 to 255  r,g,b  values by 4 to match the  0 to 1023 PWM range         
pwm(Gpin)=g*4
pwm(Bpin)=b*4
return

'----------- End ------------



This last script is for any device with neopixels connected to gpio2    view neopixel demo vid

Basic:

'Simple UDP Neopixels Controller - developed on Annex 1.41 beta2 - Electroguard
neo.setup 12          'number of neopixels, example is for a 12 pixel ring, (Data In connected to gpio2)
neo.strip 0,11,0       'neopixels off
udp.begin(5001)      'change port number if wished, but must match with Toolkit UDP Console port setting
onudp udpRX
wait

udpRX:
neo.strip 0,11, val(udp.read$)
return

'----------- End ------------
