Hello Jim, Thanks for your help with the encoder. Your code works perfect. I figured out what the problem was with me not getting a constant reading from my...
In IC and on the SUMO11 with the expansion board I think the sonar() function should work. You need to wire the trigger to the digital out and the signal to...
I donlt think I understand your question. What “some other device” where you interested in using? What kind of signal does the “some other device” want...
Hello, I have a problem with my bot. When it goes into tight spaces; the left IR will cause it to turn right, then the right IR witll cause it to turn right....
Duane, Check out this link on the Acroname website, everything that works for the Handyboard should work on the Sumo11 with little or no modifications. ...
I was looking over the code from the acroname web site. What confused me was the digital output. Doesnt the sumo11 use different output lines? Here is a code...
Actually, that code should work as is. The TIC3 line is on Digital input 7 and pin 9 is the I/O. Note that pin 9 is the left most of the two center ports as...
Thanks, Dan. It does seem to work as is. I have a question though. When I run the code, it prints out values across the LCD, and beeps. However the values...
Yes, I am. It seems to be firing off correctly, but is giving me random results ranging from around17200 to 19400. These values seems to bounc around thouse...
Be sure you are allowing the previous echo to "fade away before you try another. Allow at least 60ms between pings. You might be able to get away with 35. ... ...
Thanks Jim. I tryed changing the time between echos to 35, as well as 60. Although the values are different, I am still getting the same values regardless of...
A device that reads the ouput on an encoder for a certain fix time and output the speed of the motor to the Sumo11. The idea is that I don't want to you use...
Any approach that uses digital measurement will always be some previous speed, not the current. My feeling is the error in the delayed reading would only be...
Thanks for your advise, I'll do a little more research to see if I can get anywhere with that. Another question for you, is there anyway I can control a small...
I have seen the motor ports used to operate even larger relays, There is always a concern for ground differential problems so another choice is an opto...
Ooh that is interesting, how does that work? Where can I get an Opto Isolator to work best with the sumo11? Also, aren't those LEDs used by the servo's output...
I can’t take the responsibility of completely educating you, For one thing, I am not really qualified to teach this topic. Do a google search on the terms...
Hello, I was wondering. Is it possible to comunicate serialy from the sumo11 to another board, (bs2px). I have a mild understanding of how to send and recive...
Here's a couple of thoughts: 1- Use the "Wheel Watcher" optical quad encoder to do all the work of decifering speed and direction. I've been told by the...
Duane, The DB9 connector on the Sumo11 can be used as a common serial com link to other devices, though it is RS232 level shifted and would require that the...
Thank you. Dan. I'm not sure if the bscpx does offer rs232 level shifting. But I do belive that I have read of a few people pulling it off with a max232. I...
Hello all, I am using the sonar sensor sr04 with the sumo11 using the following code: persistent int dist_test[50]; void main() { int j; sonar_init(); j = 0; ...
I tried a range of sleep times, but I'm still reading a constant number of tics that dances around the 1100 region. I was using the port 7 for an encoder...
If you still have the encoder module loaded that is probably it. ... From: Sumo11users@yahoogroups.com [mailto:Sumo11users@yahoogroups.com] On Behalf Of Belal...
But I changed the encoder port to port # 8 and I'm using port 7 for the sonar. I recycled power to the sumo11 several times but still no real results. The...
I am not sure. Both the encoders.asm and the srf04_sonar_asm use TIC3. There certainly is a potential for interference. ... From: Sumo11users@yahoogroups.com...
