I'm not sure if this will help or not, but try going to http://www.al-williams.com/gp3.htm and download the Linux library example from there. This is a board...
Still having problems.... I am using the memkey with the grayhill keypad. I adjusted the program so that when key 1 is pressed then I get a 1 and 2 is 2 and so...
Also, FYI, I'm currently using an ISL9N302AP3 logic FET http://www.fairchildsemi.com/pf/IS/ISL9N302AP3.html to drive a diesel glowpin that draws >20A DC(0.5ohm...
Jon , feel better already! One last query on your stepper code ('cos bad habits die hard!) Will you please explain what is happening here, stpIdx = stpIdx + 1...
I have checked throughout the Parallax site and a lot of links without success. Is there a Quickcam like camera that interfaces with a Stamp? The Stamp may not...

I think that there is some merit here with using the PWMPAL. It has been said time and time again that the PWM signal coming from the stamp is not exactly...

The modulus operator (//) can be a real timesaver. Modulus returns the remainder of a division and will keep a value in a 0 to N-1 range, where N is the...
To answer some questions about what I'm actually doing, I am attempting to use the variable PWM to control the motor from 0 to full throttle. I'm not sure what...
Hey, guys and gals... This is really cool: http://www.eeggs.com/items/27494.html Secret message in the Stamp... You've been holding out on us, Jon :O) TTYL -...

Technically it's not an Easter Egg because it is being placed there by the user. Now, things like the HYP and ATN functions that went undiscovered (our boss,...
FYI, No where in the previous messages did I see anyone mention the need for a high speed recovery diode across the DC motor. Without one, the DC motor will...
... How exactly does this work? I assume that it is something that some engineer went out of their way to implement. I can't see how simply writing a string to...
Ron, Good point!... inherently there is a diode formation from the substrate of the MOSFET anyway, but this is usually considered a "weak" diode and should not...

The program is simply writing to program space what the compiler would given the correct instructions. You can make your own program like that by using the...
... Yep, the PWMPAL is really handy for my application which is a controller for a 32KBtu/hr diesel fired coolant heater. I use one channel to drive a fuel...
Has anyone seen or knows where to find any past information on possibly using a BS2 to make a wind direction indicator? Thought I saw something a while ago,...
On the current parallax home page if you click on "machining tips for robotics" you go to an article about a tachometer based on a Melexis 90217 sensor. Does...
Please save me 10 minutes and tell us what the message is. ============ Hey, guys and gals... This is really cool: http://www.eeggs.com/items/27494.html ...
I have a BOE and a Super carrier board. The Red-i module that Parallax sells 'fits' the BOE (orientation is correct)- but it is 'backwards' on the super...
Hi, does anyone have information or sites which explain how a standard model radio transmitter can be hacked to accept serial data from a BS2 and consequently...
SPSTR was unintentionally omitted from the manual. As I frequently recommend, use the Help file as it is easier to distribute so it contains the latest...
Hello, In my weigh scale the BS2 gets reading from A/D and display it using MAX7219. I want to display the reading in step of "5" for example so that the ...
