Re: Minimum Logic Battery Voltage

Depending when we order headers they can be slighly different. There are a couple different manufacturers we use. But they should have no effect on the voltage rading. However there are errors in the voltage divider resistor resistances. All resistors have some varience. But I dont think that has an...

Re: Reading current with Roboclaw

Another thing that can affect the current reading is the drive method. Locked Antiphase tends to have more noise near full power while Sign magntiude tends to have it at the low power. The current reading is timed to take place in the middle of the high side pulses. For sign magnitude this means the...

Re: Firmware update timing out

I think I know the problem. I changed the read timeouts to 10ms across the board in IonMotion. That is because packetserial has a maximum of 10ms delay for timeouts. However I also changed the readtimeout for the firmware update code which is not quite long enough. It can take a little longer than 1...

Re: S4/S5 enable

I think I know the problem. Im fixing it now and will have the update up later tonight. I chaneged the timeouts to 10ms on the read functions. This is fine for normal packetserial commands but may be a problem with the bootloader on some PCs. My work computer is new and very fast so it never saw the...

Re: Reading current with Roboclaw

Hmm. Is your load constant? If the load is constant I would expect the current to stay about the same or drop slightly under a constant load. The fact the roboclaw in this situation is showing a slightly higher current reading at lower duty points me to noise being the problem. You may have no way o...

Im publishing the new release now. I also updated the python examples a little if you are using those.

Re: Reading current with Roboclaw

Are you reading the battery amps? Battery amps are not motor amps(which is what roboclaw reports). Battery amps are only the same as motor amps(assuming one motor is being used) when the motor is at 100% duty. Anything less and the amps will be some fraction of the motor amps based on the duty %. Eg...

Re: S4/S5 enable

I was able to reproduce the S3 E-Stop problem. After power up but without doing anything else the S3 mode does not get set. It appears it was an order of operations error. If I re-read the settings S3 worked correctly. I reordered the pin setup code so it wouldnt be a problem anymore. I've tested it...

Re: new manual

Before I replied to your post I downloaded the Arduino library from our website and looked at the cpp file. It has both the GetEncoders and GetISpeed command in them(Lines 806 and 811 respectively). Are you downloading directly from our site? If so please tell me the link you used so I can check it....

Re: PacketSerial problem with FW.ver.4.1.10

I cant find any details on starDuino. If it is a Leonardo clone it should run 38400 correclty. However there is a special firmware for 32u4 that runs at 8mhz instead of 16mhz(this allows those special boards to run at 3.3v instead of 5v). Running at the slower rate could cause problems at higher bau...
