 | | Anybody's French ?
|
|
Hi all! As I plan to build a Handy Bord, and as I am a bit far away from USA, I just would like to know if there is anyone living in France (and maybe in/near Paris?)... Electronic components aren't really cheap here, so if I could share tips about (...) (27 years ago, 23-Oct-99, to lugnet.robotics.handyboard)

| | Re: Analog port shaft encoder
|

Tried what you said Joshua, I went through all the analog ports and manually fed them with a TTL signal from a function generator at a relatively low frequency of 5Hz and wrote this little test code to test it. In this example, the sencdr3.icb has (...) (27 years ago, 23-Oct-99, to lugnet.robotics.handyboard)

| | Re: Analog port shaft encoder
|

Rob, Another suggestion for debuging your setup would be to write a program which; 1, anually counts the pulses from the encoder, and writes them to the lcd screen; or 2, Just writes the state of the encoder input to the screen (a 1 or 0). Then you (...) (27 years ago, 23-Oct-99, to lugnet.robotics.handyboard)

| | Analog port shaft encoder
|

Hi, I am having great difficulty trying to get my shaft encoder to work using both sencdr3.icb or fencdr3.icb driver. I am using the QRB1114 optical sensor connected to analog port 3 with a current limiting resistor of 330 ohms for the emmiter and (...) (27 years ago, 22-Oct-99, to lugnet.robotics.handyboard)

Hi, I've seen this referenced, and grabbed the link that someone provided the other day. I've had a look at all the different manuals listed, but I can' work out which is the right one to grab. My handyboard has the 68HC11A1FN part number. Can (...) (27 years ago, 21-Oct-99, to lugnet.robotics.handyboard)

(...) Yes, I have done it, perhaps others. I use mine nearly every day connected to a GPS, but it has nothing to do with robotics. You're a bit off on your accuracy though, the spec actually says you'll be within 100 meters 95% of the time. I think (...) (27 years ago, 21-Oct-99, to lugnet.robotics.handyboard)

Hi, finally my Vector2X works! Just because of the wrong selection of transistor. Guide comes from Tom Brusehaver (1997). Thanks! Any way, the result seems not consistense as the heading 'hang' when I turn off the HB and on again later. Instead of (...) (27 years ago, 21-Oct-99, to lugnet.robotics.handyboard)
