Re: SOLVED: IonMotion Interface Hangs on Connect

Good information, Ibrahim. I'll add Im adjusting it so it wont take so long for the popup to come up if IonMotion has problems automatically entering bootloader mode. I just checked and negative numbers do cause an exceptin. 0 didnt though and shouldnt since 0 is a valid accel setting. When 0 is set...

Re: S4/S5 enable

Ok. You haev S4/S5 set to Home(user) which means the roboclaw will only stop the motors when it sees a falling edge on the signal input(M1 for S4 and M2 for S5). Try to narrow down what is happening with the motor kicking when powering up. Is the home signal triggered or not? This could indicate som...

Re: Change communication format

USB communications(assuming you are using the latest firmware) is always available. The mode the Roboclaw is set to doesnt matter(anymore). The only catch is when using RC or Analog mode those inputs will control the motors. Any packet serial commands sent over USB to control the motors will have no...

Re: S4/S5 enable

I looked at the code and E-STOP is checked before everthing else. Are you using latched or un-latched E-STOP? If E-STOP is triggered the motors should stop no matter what even if the homing routine is running. I'll have to wire it up and test it to see if Im missing something. The S4 and S5 pins(and...

Re: Mode 40 which is Speed Accel Mixed does not seem to work

I think I found the problem. It appears the bug will affect commands 40 and 46(dual motor commands that use a single accel argument). We are working on a minor update which adds support for our 2x7A motor controller. I should have this fixed in that release. Until then you should use either the comm...

Re: 43 - Buffered Drive M1 / M2 With Signed Speed And Distance

The Distance commands will not stop instantly. There is a bug in an older firmware version that would stop instantly(or nearly instant) when going in a specific direction, but the commands are not designed to stop for you. To make a movement(start move stop) you must send TWO commands. One to tell t...

Re: Packet Serial Issues with Arduino

You can check if your arduino libraries are up to date by checking the roboclaw.h file. At the bottom of the H file you should see these lines: void crc_clear(); void crc_update (uint8_t data); uint16_t crc_get(); If you dont have these functions defined in your arduino library then you have the old...

Re: S4/S5 enable

The home function runs before the main loop. The USB autodetect runs in the main loop so no USB until the home has completed. Ill look at S3. Its mode is set before the home functions execute. S3 should trigger(if set as an E-STOP). But I dont think I ever tested using an E-STOP while the auto homin...

Re: Reading current with Roboclaw

Current readings are 16bit values not 8. So you are only seeing the low 8 bits. The 16bit value is in 10ma increments so to get amps you divide the returned value by 100. The readings in amps are fairly accurate but we include the noisy milliamp data so users can filter the data however they want if...

Re: Minimum Logic Battery Voltage

No. 5.5v is minimum logic power because the 5v bec requires atleast that much to produce the 5v rail. However if you supply regulated 5v to the 5v rail and disconnect the Logic battery jumper that should bypass the 5v BEC on the roboclaw. But that 5v you supply must be regulated.
