Hey guys,
So Zenta had pretty much convinced me to buy the T7C heli transmitter and receiver, anyway very cool remote, it’s too bad that the remote cant use more switches at once as when used as 4 switches become dead when only configured for this type of usage…
I guess all the other channels are used for mixing… I do not own a heli or a plane so I don’t know… Anyway down to business.
Zenta has shared with me this code that was originally made by "Xan and numerous other people who chipped in "allows me to use the un modified T7C transmitter “7 Channel” for controlling the phoenix with bb2 and ssc32 basically the configuration is as follows
Left stick Horizontal = phoenix turns on its Z axis
Left stick Vertical = Raises and lowers Phoenix
Right stick Vertical = moves phoenix forward
Right stick Horizontal = Moves phoenix left and right
Channel 5:
3 state switch controls which mode the pheonix is in
mode 1: walk mode
mode 2: not walk mode but stands still and allows you to rotate and yaw and pitch while legs are locked to the ground
mode 3: GPmode plays sequences if you have the extra eeprom chip in the ssc32 for pre programmed moves and such.
channel 6:
VR pot that controls how fast the gait is executed
900-2100 output 900 being slow 2100 being max… "My opinion I don’t think this is really necessary as you should be able to simply use the right vertical stick to control the speed of the phoenix…but that’s just me…
Channel 7 is a momentary 2 state switch it is either at around 900 or 2100 decimal out via when read by the pulsin command “1500 is centered and this switch will never see 1500 value out on channel 7”
when in mode 1, pressing channel 7 will change gait type.
when in mode 2, pressing channel 7 will change something I forget but there are only 2 modes.
when in mode 3, this also does something “I do not have the eeprom chip in my ssc32 to be able to tell what it does although this is commented in the code quite a lot!”
So what I have done with this code is cannibalized mode 3 the original code has been commented out with ; the things I have commented out have two ;; so you can tell what I have done.
The goal of me hacking up his code is to want individual control of a leg for remote tentacle action per say… zenta had modified the ps2 remote code so RC could be used here is a video of him using his remote and showing it off
youtube.com/watch?v=72MY5GuHSpA
Anyway to activate this you would put the switch in state 3 and the robot would be stopped and moving the right analog stick one leg would be RC control and the code would just loop though controlling those 3 servos and the remaining 5 legs would be stuck to the ground.
In zenta’s video he is in mode 2 to make the phoenix lean backwards then went to mode 3 to get individual leg control propped up that leg onto the boxes and then switched back to mode 2 and wiggled a bit to let people know that that leg is locked in 3D space "as you can tell the plastic boxes don’t slide around when he tessellates the phoenix.
After that leg control is accomplished I would really like using that channel 7 momentary switch when in mode 3 “individual leg control” to change which of the 6 feet would be individually controlled.
the idea is to try and cram a lot of features use full or not into this robot without having to have the end user modify his transmitter.
I managed to find an 8 State rotary dial that stacking the correct resistors “zenta used 150 Ohm ones” you should be able to take the channel 6 VR pot and switch it on and off so that you have 8 roughly stable values when read with the pulsin command on channel 6. I still feel with the OEM setup a 3 state switch on channel 5 and a 2 state momentary on channel 7 you can program in an awfull lot of features without having to tear open your transmitter “No offense zenta” I love taking things apart like the rest of the gang 
with that part said above here is the problem I face.
Using the original code Zenta has provided me is special code he wrote for someone on the other tossin robotics forum to use the T7C but not modified like his controller preciously which code I would like to start with after playing with this code I realized that mode3 which was GP player completely crashed the BB2 and it had to be reset after some looking into it zenta had mentioned to me I needed to pick up an eeprom for that socket in the ssc32… well frankly this feature didn’t really fancy my taste buds and I wanted to do the individual leg control as I explained above so I decided to remove this code and use mode 3 for that.
When I had cannibalized his code I could no longer raise and lower the phoenix channel 3 was un responsive and I really had no idea why.
I have a feeling its something very very easy that I am missing, but it has to do with nested loops that I have a hard time keeping track of “I’m sure every programmer does” anyway enough of me babbling here is zenta’s orignal code untouched by me.
;Project Lynxmotion Phoenix
;Description: Phoenix, controlled by a Futaba T7C remote
;Software version: V1.3
;Date: 20-10-2008
;Programmer: Jeroen Janssen (aka Xan)
;
;Hardware setup: ABB2 with ATOM 28 Pro, SSC32 V2, PS2 remote (See further for connections)
;
;NEW IN V1.3
; - Changed controls L1+ right stick
; - Balance calculations Thanks to KÃ¥re Halvorsen (aka Zenta)
;
;RC control:
;Select between walking, movement and GP player mode with the 3-state switch
;Use the two-state switch to toogle between the different gaits, movement or GPsequences
;In GPMode start GP player by moving the right stick upwards
;
;KNOWN BUGS:
; - None at the moment ;)

return so Zenta had sent me a PM to assist me in trying to figure out why this doesn’t work and told me that in the main loop of the code comment out these two pieces of code

How’s that for the longest post in thread history!
anyway let me know what you guys think.

wonder about a tail of sorts … any of you guys see those green laser pointers they modify for burning … bad idea I know but a walking spider with the ability to burn holes in things … REMOTELY… toss on a pan and tilt camera and you have a miniature WMD haha horrible.
Crappy economy indeed.
