Notes: This shows the Robosapien iR(infrared) tapped into using the RAMB board and the Basic X 24 Microcontroller, the chip is on the Ramb board, look above for pictures of the actual hardware.

A few notes to meantion for “advanced” users this RAMB board has cut out some of the Pins BX-24 uses for other things, and were not added, so no one “screws” it up, I will post a PIN # diagram so stuff will be alot easier, look for that in the comming day or June 13-14

I learnt this from reading documents on BX-24 RS related Mateiral off his site, which is in my links if you want to check it out, he also has alot of other BX-24 RS mods he has done. but I am pasting his documents below since they are all finely tuned :-) you could say

A word of Caution... DO NOT try to drive 5V TTL levels from the BX-24's Outputs to the Controller Board's Inputs or you will Damage the Controller IC! The following schematic is a simple SCHOTTKY Diode Clamp which will 'Clamp' the BX-24's Output to within 0.3V of VCC (3.3V):

You can use most any SCHOTTKY Diode (DO NOT use a Silicon Diode!). I'd recommend the 1N5817, 1N5818, or 1N5819 since they are easy to find. The following describes how to install it. Refer to the diagrams below: Looking at the back of the controller board with the longest side on top, note the 10-pin connector that connects to RoboSapien's Head. The third pin from the left is the IR input and there is a blank pad just to the lower left of the pin labeled "IR" or "IR-OUT". Connect the diode's Anode to either the pin or the pad.

Now, looking at the upper left 4-pin connector, while it's not labeled, the third pin from the left is VCC. On my board the left pin is labeled "M4+", the next is "M4-", the third is not labeled and the fourth is labeled "P1.6". Slide some heat shrink or other tubing over the diode and connect it's Cathode to this pin.

Next add a 2.2K resistor from the BX-24's Output to the IR input where the diode's Anode is connected. You can use any wattage resistor like a 1/8W or 1/4W or even an SMD package.

To isolate the IR Sensor, remove the 3rd wire from the Female connector that connects to the IR Input on the Controller Board. In my case, it's a White wire. Connect this wire to the pin you are using on the BX-24. The reason for this is that pin is used for the InputCapture() procedure.

In my interface, I used Male and Female 'break-away' headers based on 0.1" centers and ribbon cable. These are real common and easy to obtain. I used a 2-pin Male header connected to the resistor above and GND on the Controller Board header. Next, I used a single wire soldered to the IR Sensor wire with Heat Shrink tubing, connected to a single Female header. That allows me to either connect the two for normal operation or isolate them for connecting to the BX-24.             - Thandley

BUILDING A PROGRAM TO GO WITH ROBOSAPIEN...... IR CODES/ HEX CODES AND BINARY  AND CODE FOR BASIC X PROGRAMMING, HOW IT ACTUALLY WORKS...

But why not take a 'Chance' and get to know what Binary really is, well not really, but an understanding of it... got 0-1 minute ?? ;-)

This is a list of IR Commands referenced to the RoboSapien manual. Values
are in Hex and (Decimal) format. For a complete list of standard and secret
commands as well as detailed IR timing information, check this site:
http://www.aibohack.com/robosap/ir_codes.htm
I have modified this list to display the Binary Value of each command for people who use Robodyssy, or my Program, as well as give you an understanding of what is actually going on

Tutorial on Binary: thought it might be good sure helped me ;-)

Humans have ten fingers, and so it's not so surprising that many cultures throughout history have used base 10. Digital computers use base 2 or binary number representation, each digit of which is known as a bit (binary dig it). Here, each bit is represented as a voltage that is either "high" or "low," thereby representing "1" or "0", respectively. To represent signed values, we tack on a special bit -- the sign bit -- to express the sign. The binary addition and multiplication tables are

0 + 0 = 0
1 + 1 = 10
0 + 1 = 1
1 + 0 = 1
0 + 0 = 0
0 + 1 = 0
1 + 1 = 1
1 + 0 = 0

(1)
A carry means that a computation performed at a given position affects other positions as well. Here, 1+1=10 is an example of a computation that involves a carry. Note that if carries are ignored, subtraction of two single-digit binary numbers yields the same bit as addition. Computers use high and low voltage values to express a bit, and an array of such voltages express numbers akin to positional notation. Logic circuits perform arithmetic operations.

ok so were going to find out where each binary bit is placed on the BX-24 basic X coding....
 

AC (172) - Left Hand Pickup 10101100 (hex, decimal, Command, binary)

it is really simple to sort out 1 being highbit, and 0 being the lowbit
the coding is simple on the BX- as a simple 1 is represent by a "HighBit" name ....

Call Pulseout(Sapien,HighBit,1) 'This equals 1 Binary
Call Pulseout(Sapien,Clockbit,0)

The 0 is represented by

Call Pulseout(Sapien,LowBit,1) 'This Equals 0 Binary
Call Pulseout(Sapien,Clockbit,0)

-------------------------------============================================-------------
REFER TO THIS EXAMPLE TO SEE HOW EACH BINARY BIT IS PLACED

Sub LHandPick()'Left Hand PickUp '10101100 would be displayed something like this on the chip

Call Pulseout(Sapien,startbit,0) ' bit to start sending commands

Call Pulseout(Sapien,HighBit,1) '7 bit 1
Call Pulseout(Sapien,Clockbit,0)

Call Pulseout(Sapien,LowBit,1) '6 bit 0
Call Pulseout(Sapien,Clockbit,0)

Call Pulseout(Sapien,HighBit,1) '5 bit 1
Call Pulseout(Sapien,Clockbit,0)

Call Pulseout(Sapien,LowBit,1) '4 bit 0
Call Pulseout(Sapien,Clockbit,0)

Call Pulseout(Sapien,HighBit,1) '3 bit 1
Call Pulseout(Sapien,Clockbit,0)

Call Pulseout(Sapien,HighBit,1) '2 bit 1
Call Pulseout(Sapien,Clockbit,0)

Call Pulseout(Sapien,LowBit,1) '1 bit 0
Call Pulseout(Sapien,Clockbit,0)

Call Pulseout(Sapien,LowBit,1) '0 bit 0
Call Pulseout(Sapien,Clockbit,0)
--------------------------------------------------=======================

Definition of these Values..... and how they add up to one full command (walk forward)

This code listed below is inserted at the beginning of your project so each bit of binary can be properly converted and used to move your Robosapien robot.


Public Const StartBit as single = 0.006664 'Time it takes for the start bit to start a command

Public Const LowBit as single = 0.000833 'Time it takes for the low bit = 0
Public Const HighBit as single = 0.003332 'Time it takes for the highbit = 1

Public Const ClockBit as single = 0.000833 'Clock bit time ' second # in the 1binary bit code = 0

you place a start bit at the beggining of each command you are going to create.. so you would do this by


Call Pulseout(Sapien,startbit,0) ' bit to start sending commands

now we have to call the HIGH/LOW and Clock Bit for each bit of Binary we have to deal with. We have 8 peices of Binary, which means that we will basically have 8 questions, with an a) an b) value making the final value for that bit of Binary ....

This is a very easy thing to do, as we can sort out 1 or 0 for each 8 of the Binary values by seing if it has a HighBit or a LowBit Value in it....

Call Pulseout(Sapien,HighBit,1) = 1 binary bit

Call Pulseout(Sapien,LowBit,1) = 0 binary bit

followed by the next command which gives a 0 binary bit to the ClockBit Value...

Call Pulseout(Sapien,Clockbit,0)

Full code would look like this

Call Pulseout(Sapien,HighBit,1) '7 bit
Call Pulseout(Sapien,Clockbit,0)

and once calculated using this little chart below or binary tutorial above we will get 1 full binary bit Value to the 8 Bit Value that is needed to do a command on Robosapien


0 + 0 = 0
0 + 1 = 1
1 + 0 = 1
0 + 0 = 0
0 + 1 = 0
1 + 1 = 1
1 + 0 = 0

so that example above:


Call Pulseout(Sapien,HighBit,1) '7 bit
Call Pulseout(Sapien,Clockbit,0)

Would be a Binary value of 1
