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.

Re: Packet Serial Mode: Multiple Motor Controllers
Correct, if you enable the multi-unit mode you wont need the diodes anymore because the TX pins on the Roboclaws will only drive low or float. You will still need the single pullup on the controlling microprocessors RX pin(eg: the arduino).

Re: Commands 38,39,40 wont return Ack flag but work ok
Show me what you are doing in a little more detail. If you are usign the ISpeed(eg the raw speed) commands then you can get a lot of 0 velocities so you have to filter that data yourself(thats the purpose of the raw speed comands so you can filter it however you like). Once you filter it(a simple av...

Re: new firmware issues - 4.1.13
Good to hear it is working properly now. Your procedure for updating the firmware is basically how it use to have to be done always. We added the autobooload command but if that fails using your method is the best fallback method. It should always leave you with a clean USB connection and it will al...

Re: CRC16 - Visual Basic - SOLVED
Thanks for the VB code. Im planning on writing an example using VB.NET and the roboclaw.dll sometime soon. Just dont know when yet.

Re: Mixed Mode commands 10, 11 and 13
You can send any mixed drive commands only when you are using the mixed commands. You can use the mixedforward, mixedbackward or mixedforwardbackward commands. Then you must use either turnleft,turnright or rightleft commands. After sending the second command the motors will start moving. Once you h...
