Throttle Range #5

Open droter opened 11 years ago

droter commented 11 years ago

When using the 901SM setting the forward to 114 and reverse to 123 is the max speed I want to go. Is there a way to adjust the throttle range?

FrancescoFiorentino commented 11 years ago

With the original Arduino sketch that control the radio sender, the signal to obtain max forward speed is 0, and for max backward is 60. You have to write this value on the serial port (COM3). With the Arduino sketch that I wrote, the signal is comprised between 0 and 30, where 0 corresponds to no movement, and 30 is the max forward speed. Backward is not contemplated.

Now I don't know what sketch is charged on the Arduino board.

We are looking to increase the resolution. When we use the handheld transmitter you can drive the vehicle the full range from slow to fast. Some of the handhelds allow you to change the range of the throttle so full on is only half power. Is there a way to do that with the 901SM?

Have you tryed to do it via software? Which platform are you using? Matlab or Visual Studio?

I am just running the debugging step function inside of arduinoSender.ino connected to the transmitter. I am trying to calibrate the throttle. So I am just changing the throttle value by one going from 80 - 120 with no offset. The wheels start to turn at 115 and full throttle is at 112. (steering_signal_data[THROTTLE]). I need more control of the throttle.

Those data sounds strange to me. With the original Arduino sender, the signal for the throttle was comprised between 0-60(where 0-30 means forward, 30-60 means forward). For the steering the signal was comprised betweenv 128-168. I don't know if you changed something in the program. But I remember that, depending also by the car, there were some abnormal behaviours.
