Irobot 530 Quick Advice

Skip to comments   Jump to end

Hi guys.

I am currently looking at a Roomba IRobot 530 on a popular auction site I want to get. I don't wish to appear rude but I need some quick advice before I place a bid, as the clock is ticking. eek

Does the 530 have a comms port to connect the EZ-B4?

Is the 530 compatible with the EZ-B4?

I've never had a robot vac so it's all new to me. I know DJ does reference the iRobot but there's no mention on models.

Cheers.:)

For two byte data this works for Roomba's voltage check



REPEATUNTIL(IsConnected(0)=0)

  uartinit(0, 1, 115200) #have to have this to clear the buffer
  sleep(1000)
  $RX_DATA=0
  uartWrite(0,1,142,22) # Volatge check
  sleep(50)
  $rx = UartAvailable(0, 1)
  
  
  IF ($rx=2)
    $RX_DATA = UARTRead(0, 1, $rx)
    $MSB=GetByteAt($RX_DATA,0)
    $LSB=GetByteAt($RX_DATA,1)
    $voltage=($LSB+(256*$MSB))/1000
 
    
    print($voltage)
  ENDIF 

  IF ($voltage<13.9)
    uartWrite(0,1,143) #seek dock
    print("Low battery, attempting to dock")
    halt()
  ENDIF 
    sleep(9000)  #check every 9 seconds
ENDREPEATUNTIL

@Richard.

That last script, is that to be used with the TX D5 pin or how I have it connected now with the RX D6 pin?

EDIT: Scrap that. I just re-read the code and see it's for RX.

Hey Richard. I just tried the sensor script but said there was an error on line 22 with variable not defined...

Also had an issue with the volt check saying syntax error unknown command volt_check=1...

Make sure you have receive wire to pin 6 of the ezb.... Also make sure you use the init script first

You will need 3 wires... ground Rx from Roomba... Pin 6 on ezb Tx to Roomba ... Pin 5 on the ezb

Sorry mate, still not happening. I've been using the init script and have the RX and TX connected now, but on both the volt check script and sensor script, I'm getting "variable not defined: $RX_0". The power on script didn't work, but thinking about it the Roomba would need to be on in the first place to receive a command (kinda like pressing the On button on your TV remote with the TV unplugged).

@Steve...that's weird because it works on my Create 2. However the Create 2 is a Roomba 650 not a 530. I do have a Roomba 530 and will check it out tomorrow...in the meantime check your receive wire and make sure it's soldered to the correct pin on the mini din connector... I don't think you're getting data back from the Roomba....msg you tomorrow when I check my 530...

You can strap pin 6(gnd) and pin 5(DD) of the 7 pin mini din together and that will wake up the Roomba.
