Flex Chaser is an LED design software that allows users to simulate patterns on predefined channels. It supports up to 32 channels. Users can name and save files, select a microcontroller, assign port numbers to channels, design effects that move from left to right or vice versa, insert effects to memory, review and edit effects, create an IC file to burn onto a microcontroller, and load the file onto a driver card connected to an LED or neon sign. The software can be used to sequence decorative lighting, signage, and more.

A Demonstration
Designed and Developed by:
230 A.J.C Bose Road, Kolkata,W.B, India

2. An Introduction
• Flex Chaser (FC) is an innovative LED
based design software that helps you
simulate designs and patterns on pre-
defined channels.
• It can be mainly used for sequencing
of LED’s and Neon Lights.

3. The Front-End Interface

4. Step 1 :
Name the file and save it. This can be
used later on also for editing.

5. Step 2:
FC supports upto 32 channels. For e.g, if we want to sequence a
signage board ‘WELCOME’, we would require 7 channels,
assuming that each letter in ’WELCOME’ is made of a single
colour LED. If you intend to use/backlit more than 1 colour, choose
the no of channels accordingly. So, if we use 2 colours (say Red
and Blue), we will need 14 channels for sequencing them.

6. Step 3:
1. Choose the microcontroller that you would like to
burn your final file into.
2. Note that FC works only on the 8051 architecture. It
does not support any other controller.
3. Depending on the Code memory, the memory space
will automatically be allocated.

7. Step 4:
1. Once you have selected the number of channels and the
controller, assign the port numbers for the channels accordingly.
2. Freeze on your selection and you’ll see the Grid on your right.
3. We are now ready to work on our sequencing. Let’s assume that
we have selected the AT89C51 with 32 channels

8. Step 5:
1. Let us design and effect which will light up your
Sign Board from Left to Right.
2. As P0.0 of 89C51 represents our 1st Channel,
let’s select that.
3. As we want to light up our board, one after the
other, we select the channels accordingly until
the 32nd one.
4. Then, we light the whole board.
5. And then move from Right to Left.

9. Step 6 :
Once done with our effect, ‘Insert To File.’
This will clear the Grid Panel and insert
your pattern in memory

10. Step 7 :
1. As many as 250 effects can be selected in
FC.
2. Note that this depends entirely on the
memory /space left based on the controller
you’ve selected
.

11. Step 8:
1. Choose from various options like
varying of speed within the Effects
2. Repeating a single frame a number
of times (upto 250*10ms)
3. Insert to File again to store in
memory

12. Step 9 :
Before finalizing on the effects, review your
effects before-hand using the ‘Play Effect’
option on the main window.

13. Step 10:
1. Once done click on ‘Create IC File’
2. This will prompt you to save your
file and use it as many times as
required in the future.

14. Step 11:
Once you save the file, it is ready to be
burnt into the micrcontroller. You’ll have
two files created, one an intermediate file,
and, second the final file.

15. Final Step:
Navigate the final file that you have created
and load it in your programmer.
Burn it in the Controller and it’s ready to be
inserted in the driver card that is connected
with your LED / Neon Sign board.

16. Some Points to note:
• We will provide you with complete
schematic diagram and PCB’s if
required.
• The main hex file thus created, can be
used with LED’s or Neon Lights or any
kind of Signage. What changes is the
driver card, not the software.
• Depending on the Load, the driver
card is to be designed.

17. Applications
• Neon and LED Sequencing
• Decorative Lighting
• Discotheques
• Backlighting
• Cove Lighting
• Interior and Exterior Lighting

18. • We feel that this software is must-have
for anyone related to the Signage /
Lightning Industry.
• We’ve tried our best to explain you the
use of our software. If, however we
missed on certain things, please mail us
at contact@insforia.com and we’ll be
glad to assist you!
• We also hope that you enjoying using it
as much as we enjoyed creating it.
