So I have this here parallax stamp board which based on the documentation I can't find on the internet I came to realize must be quite old.
I have been using the documentation here (warning: it's a 4+ mb .pdf file) in order to get started with it. However I found that although the leds light up when loading the code below onto the board, the servo connected to the "P12 pins" (in the picture not connected) will not start turning as it, according to the .pdf above (page 92), should.
The code:
' Robotics with the Boe-Bot – ServoP12Counterclockwise.bs2 ' Run the servo connected to P12 at full speed counterclockwise. ' {$STAMP BS2} ' {$PBASIC 2.5} DEBUG "Program Running!" DO PULSOUT 12, 850 PAUSE 20 LOOP
Hey, thanks for replying guys. It is indeed the Deagostini Robot which I 've had since I was …13 or something.
Seems like the connection between Vin and Vm is the case however I am getting a “No Basic Stamps Connection” (something similar to that anyways) error which according to a few pages on the internet could be happening due to low power; quite likely seeing as I haven’t changed the batteries for years.
Zappman the documentation is definetely going to be of some help even though I know little to no italian. Thanks!
your using the OEM version of the BS2 Board of Education. OEM meaning they resell it to other companies who include it in their final product - like the DEA robot. it also cost less than the regular BS2 because it comes in kit form, and you do your own assembly of the components. look at the OEM section on www.parallax.com.
I have found out that one of the servos is not functioning correctly; specifically it speeds up and slows down at some point during a complete circle. Taking the screws and the plastic cover off has proven useless since everything inside seems to have been placed securely quite well and you can’t pretty much do/change anything. Oh well.
I am having trouble, despite all the documentation, finding out which pin (of the ones labeled P0-P15) is connected to where. So far all I know is that pins P12, and P13 are directly connected to the servo slots. I guess I’ll have to go the trial and error way.
I’ve also installed a DC Motor Board on the X7 slot which, when connected to it, controls two motors giving the robot the ability to pick up and hold things. However I haven’t managed to find out how to control them through PBASIC.
(note: the pictures above are not of my robot nor have I taken them)
