Ok, so I tweaked the code a little... Might be making some progress... I am at least now getting a response back from the Create, but the characters sent back are jibberish... it's like the baud rate is wrong or something. When I query the Create's battery temperature (as per a tweaked version below) I get back what looks like the letter Q instead of a number between -128 and 128... The baud is set at 57600 and works no problem sending the Create drive commands...The Create's default baud is 57600, which it is set at....

$x="null"

uartinit(0, 1, 57600)
sleep(1000)
uartWrite(0, 1,128,132) #Init iRobot create and place in full mode
sleep(100)
uartWrite(0, 1,142,24) #Roomba Battery temp in DegC... single byte from -128 - 128
sleep(100)
$x=UARTReadAvailable(0,1)
print($x)

Halt()

I'm working on a throw it together style robot with a planned penguin paint scheme. It can be found here: synthiam.com/Community/Questions/5636 I'm getting votes on the name and on the head and now arms too. If you have any ideas let me know!

Ping Steve... Some success (thanks to DJ) ... Below is working code for the 1 byte Roomba/ Create data packets.. Still working on 2 packet data...

# Using UART port 1 TX on D5 RX on D6

$x="null"

:top
uartinit(0, 1, 57600)

sleep(1000)
uartWrite(0, 1,128,132) #Init iRobot create and place in full mode
sleep(100)
uartWrite(0, 1,142,7) #Roomba Bump and wheel drop sensor
sleep(100)
$x=UARTReadAvailable(0,1)
print(GetByte($x))
goto(top)

I will be powering Sunshine with the EZB4 (if it ever comes in).

That is Great news Richard R getting some code operating that receives packet info from Create using the EZB4. When you sent the optcode 142 for sensors packet member 7 what value did it return? Was it 1 for bump left or 0 for bump right? I have never used something like "Realterm" before, only EZ Robot send serial commands. I always wanted the bumper sensors to be an emergency stop for my robot. If bump is detected then sendserial(D0,57600,137,0,0,0,0) #STOP The opcode wait for distance, angle, work great, but ignore all other commands until the wait is complete. The cliff sensors still operate when I move my robot with serial commands, telling it to drive forward stopping at the edge of a table while I waited to catch it. The IRobot Create and Roomba have many great sensors built in. Are you still using the small Create plug, but with the extra receive wire added? I know you are using UART port 1 TX on D5 RX on D6. Can you sometime show a picture of your wire connections on EZB4 side and Create plug. Thanks for sharing your info and helping. Steve S

Steve, I got 1,2,3.... depending where I hit the front bumper... bumper is something like left=1, centre =3, right=2... something like that... never tried wheel drop... You'll have no problem using my code to detect a bumper hit and as you stated to stop the Create or turn, backup or whatever ... I'll get you a picture tomorrow... but it is only 3 wires... ground on D5, send on the signal pin of D5 and receive on the signal pin off D6... I have made both a 7pin plug and a 25pin plug... both work perfectly for this.. in the meantime I am still working on getting the 2 packet info back...

That is so cool you have EZB4 receiving info. Great job! Thank you for sharing your new EZB4 adventures! Steve S

Any new robots since? Richard R solar robot is cool and posted an update about ICreate & feedback, thanks, D.J. working on new IRobot commands, Food robot got an update and new small bot, Moshi is cool, Cathie,s son received a 6, Dave integrated EZB4 to his cool B9, Tony from UK is advancing with his great applications! I want one! Tony (Lexi) trying many options, Robot Doc with new projects, New product is shipping, Still waiting for mine from Nov 2013, but I was contacted about removing batteries, and still having fun with EZB3. I appreciate EZ Robot! Sorry if I missed others. Such a great community of people, robots and help! Thank You Everyone, Steve S
