I have constructed the circuit from the Application Note 1001 to switch my AX2550 from serial mode to radio control mode on the fly. I am powering on the AX2550 in R/C mode with the serial TX line connected, as per the AN, and then sending the 10 carriage returns to switch it to RC mode. At the same time, my R/C hardware, a Futaba receiver, is connected to the motor controller via R/C input 1. I have found that when my R/C transmitter is on, the motor controller will never go into serial mode, but will go into it as soon as I turn the transmitter off. This doesn't seem to follow what the application note implies, and the rest of the switching seems to work correctly (the alternate setting giving me two channels of R/C control) Any insight into this issue would be helpful. Thanks.

Is there any way to predict/model the regen current going into the batteries? Even better, is there a firmware update for this controller that will allow me to use a "coast" mode? It seems this controller will only current limit during braking if the current levels are dangerous for the controller, but it would be nice to have a software programmable level here. Thoughts? Suggestions? How do I keep my li-po's happy with this controller?

Thu, 18 Feb 2010 22:52:13 +0000 http://www.roboteq.com/online-forum-9031.html#29525137 Hi everyone, I have code that sets the motor speeds(once) and continually queries the encoders as the robot moves. I have run this code on two computers, a fast one, and a slower one. On the slow computer, the robot is unable to follow a straight path and ALWAYS curves to the right. On the fast machine, it appears to work perfectly. How could two different computers result in these behavioral differences when they are running the same code? What might be causing this? When I look at the serial communication LOGs, nothing looks unusual, and there are no commands being sent to change the speed of just one wheel... I should also mention that the controller is set for closed loop, using the encoders. I have the newest firmware.

The problem is the fact that the encoder values are cleared each time I read them (in relative mode), so my travel information is lost any time this occurs. thanks everyone. -Ben Wed, 17 Feb 2010 01:47:27 +0000 http://www.roboteq.com/online-forum-8805.html#29525132 When I am logging data in Roborun and go to save the log file I get a "Run Time Error 401" Message "Can't show non-model form when model forms is displayed" Controller AX2850 with Rev G firmware Wed, 10 Feb 2010 19:48:35 +0000
