Need some assistance, I have Create 2 Platform and recent purchased the EZ-bV4. in working with the tutorials on the site i as not able to get the EZ-b to control the Create 2, using the the Roomba movement panel.
I have ready multiple threads of folk having similar issues, and wanted to know if some has come up with a solution to this, I am not an electronic engineer so hopefully it will be something off the shelf.
Thanks in advance Alain
Use 115,200 protocol and select clean first.... Still the best way is what I did is create a custom Movement Panel with sendSerial commands...
Try this... It uses the UART Port 0 not D0 however... Custom Movement Panel for Roomba 500 series
Thanks for the replay but i am not sure how to connect to the uart , do you have a diagram for that interface to the create2
Look at the descriptive picture of the ezb4 here (below)... The black female header is the UART port 0 (it's labelled in the picture)... all you need is two wires to it... 1 for the ground and the other to the TX pin of the UART. The port pinouts are labelled.... Two wires to your create and that's it... Then load the Example Project I linked to above and check it out... EZB4 descriptive parts
All this assumes you have your 7pin din connector wired correctly to your create as well....
Hi Richard thanks for all of the help I wired pin 4 of create 2 to the tx of the ezb uart and the then pin 6 ground to ground, and still no luck.
Pins 1 and 2 are Create 2 battery voltage. Pin 3 is Create 2 TX. Pin 4 is Create 2RX. Pins 5 and 6 are Ground. Pin 7 is Create 2 BRC.
Now my EZb is DEAD ARRRG! I will have to send a support ticket in to see if i can get if fixed or replaced.
Thanks For your help
@Alanverdure... Before you do that check the fuse in the base... Maybe you just blew the fuse?... Be careful if you are powering your ezb through the Create's Vpow (unregulated) line as the ezb is spec'd for up to 16V only or something like that... When docked the creates charger delivers 20+ volts...
Cool will do , I was just using a 9v battery for testing. I do plan on using the creat2 power for the ezb and purchase a dc variable volatage regulator for that specific reason from the The Robot Shop,
Thanks Alain
Checked Voltage at the base and the fuse is good Rats :-(
Silly question I am sure, but did you check your 9v battery? They are not built fir this kind of application. Won't deliver a lot of amps and will drain really fast.
