Hi,
I am trying to have the EZ-B send commands to my Roomba. I have tried the Roomba Control in ARC. I have also tried using the SendSerial Command via the script console. In fact, I see no output at all from something like SendSerial(DX,115200,"hello")
I can command my roomba via a serial cable, so I know that this is not on the roomba side. Thanks
Erin
See this post
Looks like a common problem over to DJ
SendSerial at 115,200 on Port D0 works fine for my testing. I just tested. 115,200 only works on D0
Does your D0 work to control servos?
No, that's strange D0 is not working for the Servos!? The other ports seem fine though... could I have a bad board? Will SendSerial work on ports other than D0?
Check the White wire being fed to your EZ-B from the roomba with a meter. Do you see voltage from that white wire?
I made a custom cable from my Roomba. The white wire is on the roombas rx; there is no voltage on it.
I'm sorry, my mistake there is 5V on in... I'm not very good at this electrical stuff...
It's easy to damage the port by not checking the voltage before connecting. But, i'll tell you something awesome. The reason i didn't make the EZ-B with a surface mount chip is to allow easy repairs when damaged
So! You can get a new chip and plug it in. Contact Us and we'll set you up
THanks for your help DJ, I appreciate your quick response. And you are right that is definitely awesome, especially for us SW people!
