 | | Choosing a shaft encoder?
|
|
As a neophyte robot builder and HandBoard user, may I ask for help in choosing the best shaft encoder? What vendor/supplier should I use? The current project is a very simple robot with a goal of accurate navigation. Thanks! (26 years ago, 28-Nov-98, to lugnet.robotics.handyboard)

these aren't actually additional ports. if you look at the PCB wiring you'll see that they're just connected to regular inputs 0-3. these extra connectors will be used by the expansion board. please look for an official notice regarding the exp (...)

Hi, I need additional port for the analog input. I have used up 7 analog ports and 9 digital ports. Hence, I need additional port from the HD. I came to know that there are 4 extra analog port on the HD just above the analog port 0 to 3. These (...) (26 years ago, 27-Nov-98, to lugnet.robotics.handyboard)

Here's the HB 2.81 pcode with floating point divide fix. This new FLTDIV routine was giving to me by Jon Howell. I just patched the original math library with it and recompiled the pcode. I'm pretty sure this is the same fix that Newton Labs is (...) (26 years ago, 26-Nov-98, to lugnet.robotics.handyboard)

Any chance that the source for the recent pcode FP divide bugfix can be released so that it could be retrofitted to the 2.81 freeware source? I'm not suggesting that Newton Labs actually do the retrofit, just that the source for the patch be (...) (26 years ago, 26-Nov-98, to lugnet.robotics.handyboard)

This is kinda off the HB topic, sorry. How do you control the individual output states of the parallel port pins?

Hi John, It depends on what kind of circuit your infrared sensors are in. An infrared diode or transistor can not be hooked directly into the HB. They have to be biased properly and the signal amplified to be compatible with either the digital or (...) (26 years ago, 25-Nov-98, to lugnet.robotics.handyboard)
