Resolved by Rich!
I have a robo claw 2x 60 motor controller. I have ezb4 connected via DO and D1. I am connected to the EZB4 with my computer as I can send sound files to it and it plays out the EZB4. I have assigned ports DO to left motor and D1 to right motor. I cannot make the motors do anything. I have previously used this controller with a RC receiver and it worked. Is the EZB 4 not able to replicate those commands? Do I have to speak with it serially? A script? When I read the script control instruction it says something about needing a Movement Panel associated with it? Thanks ahead of time.
Does speed control work? Have you tried sending 64 and 192 to stop the motors?
Rich I just ran your script, It started 1 motor, a second later the other motor started both again in opposite directions and continues to just run. I have to pull the battery again to make it stop. Thanks for your efforts. I may see if my wife can video the set up of the robo claw for you guys to see.
I'll have a look at the Arduino library/code for it and see if there's anything "special" about it. The manual doesn't say there is but sometimes they miss out something that seems small and irrelevant but is necessary.
The script should have had both channels moving at the same time so if one started and then nothing for a second or so it would indicate there's something else needed after initially sending the 128 or 255 or whatever byte is needed.
Thanks again! I just went through the setup of the robo claw with paper manual in hand. It definitely blinks 5 times for serial mode, and then next menu 4 times for baud rate 38,400. I really hope this can get figured out as I have a second robo claw 2x 30 for shoulder motors.
Thanks everyone! Chris
We will sort it eventually, I haven't been beaten yet
It's just usually a lot of trial and error especially when I don't have the same piece of kit to test out myself.
It may be as simple as needing a carriage return at the end of the data, 0x0D in hex.
Quick example to spin both channels forwards for 2 seconds then stop;
Hey Rich Ive been poking around at basic micro forums, this seems to be a known problem since may of this year. (Motors wont stop) One of the admins over there specifically said 0 will not stop the motors, and to use the individual commands 64 and 192 (stop respectively for each motor) I will try this and see what happens. Supposedly there is a firmware update that may address this problem. Thanks for all your help. I will let you know if this stops the motors,and then we can move on from there. Chris
AHA success! It is a firmware problem for sure. Re-wrote script
SendSerial(D0,38400,127) SendSerial(D0,38400,255) Sleep(5000) SendSerial(D0,38400,64) SendSerial(D0,38400,192)
Motors now run, again in opposite directions but now STOP. Now I need to figure out how to do firmware update to the board. Thanks Chris
Cool, glad it's working.
To reverse the direction of one of the motors just use the full reverse number for forward i.e. change 127 to 1 and 1 to 127.
If you need to use 64 and 192 to stop you could use the custom Movement Panel and just throw the send serial commands in each script for the movements and in stop throw in the commands with 64 and 192 in, that would work in the absence of updating the firmware.
