The Portland Area Robotics Society announces that this year's annual contest-PDXbot'05 - will be held Sunday, May 1st this year. That's a bit earlier than...
I was trying to find out how much you charge for J-connectors. I had to have some in hand today, so I didn't go through you and had to buy the two $6 packages...
I bought my SUMO11 some while back, but I won a parrallax STAMP and I tested myself out on that. I finally got around to trying to use it tonight. 1) I...

Are there any routines to use the SPI in interactive C already present (but apparently undocumented)? Does anyone have some code I can steal for I2C in...
Ken, Check the Handyboard.com website and the Handyboard yahoo group, I've seen code that uses the SPI port as an I2C mod. Everything that works on the...
Kenneth, You can find a range of introductory IC code under workshop materials in <http://robotics.nasa.gov/edu/9-12>http://robotics.nasa.gov/edu/9-12 Anything...
... Dan, does that include .icb's? (! I knew you were trying to make a workalike, but didn't realize the extent to which you'd succeeded. Nice job, btw.)...
Ken, Yep, .icb's also work the same as on the HB. Though I think .icb's are being phased out with the new Interactive C versions, I read on one of the forums...
I asked both of these on the SUMO11 group and still feel that I don't have a clear answer. Sorry to bug you. I'm strictly a software type, and have only made...

This is just comments. Thank you both for your insightful replies. ... Hmm. I thought that the "servo" ports were all running off of the regulated power supply...
Okay, I get that I can't have the 7.2v servos and the 12v motors happy on the same (motor) power supply. Since the added servos run off a third battery source...
Sounds like a lot of work, I would recomend a different solution though. If I were going to be using 12v motors with the Sumo11, I'd invest in an external...

Dan, According to the User's Manual, I should be able to use Servo4..Servo7 in an IC program. The IDE/compiler won't accept as predefined, Servo6 or Servo7....

Hi guys, Is it possible to access the sensor ports on the Main Board with I2C and the HB expansion board on? If so, how do you call up the ports in the I2C...
John, Yes, the main board sensor ports are accessable through IC (not the same as I2C). The Sharp sensor ports are connected to Analog 2 (right) and Analog 2...
Hi all, Does anybody have an idea of how to setup a timer in Interactiv C. I want to calculate the velocity of my car. I am reading rpm's but I don't know how...
