Hi, I have few newbie questions, and a contribution to make... Background info: ---------------- I have been playing with my HB for a week now, using the free IC 2.850 under NTServer4.0... So far, Ive been sucessfully able to control DC motors, send beep()s, load and run my own .c files... Was NOT able to make analog() or knob() to work... Today I brought the HB to work and installed on my Solaris 2.4 box, where I'm running free IC 2.850 for sparc/solaris... So far I've been able to acomplish the SAME as I did on NT... Questions & Problems: --------------------- 1) According to the docs, I should run "dl pcode_hb.s19"... This is what I got under NT & Solaris: Cannot find file pcode_hb.s19 or file /home/philippi/packages/ic-sparc-solaris- 2853/lib/pcode_hb.s19 See "dl" output bellow... Why is this happening? My lib path is properly set... 2) Because of the above, I've been doing "dl pcoder22.s19", which works fine... Is it "Ok" to do "dl pcoder22.s19" instead "dl pcode_hb.s19" ? What is the difference? 3) Knob() is not available... C> knob(); Error in user interaction around line 1: Function knob undefined ...frob_knob() is available instead, but always returns 255... See "list functions" output bellow... How can I make knob() work please? 4) analog() returns 255 all the time... I have a photocell sensor (built according to docs) on analog port 1, and no matter what I do with the light over the sensor, I always get 255... Why? How can I fix that please? 5) After I load a function named main() and reset the HB, the board auto starts main()... So far, so good...:) The problem is that according to the docs, I should be able to override main() during startup, by pressing the "start" button while turning on the HB... But that's not happening... main() is outo execing no matter what... So far my solution has been putting the HB on bootstrap mode, and doing a "dl" all over again... Why is this happening ? How can I fix that, please? 6) The other day O posted a question on how to hack a servo so it turns infinitely, instead of 180 degrees only... Then I was thinking... If I do that, then I wouldn't be able to know how many turns my shaft has done, right? I would have to use a shaft encoder, right? Could I use a stepper motor instead? Would a stepper motor let me perform infinite turns, and at the same time give me some feedback on how many turns have been done? Does the HB provide any kind of stepper motor support ? 7) Is anyone archiving this mailing list ? If not, then I'm volunteering to start archiving it, convert it to HTML, and make it available throuw a web server... ...Basically, a web intercafe to the archive... I've read that Fred prefers the mainling list format, but instead of replacing the mainling list (with a newsgroup, as suggested before); I'd like to create a web interface to the mailing list archive only... Let me know what you think... 8) I'm half way through building an expectk daemon, that listens to TCP/IP requests on port 2020 (temporarely), and forwards them to IC... This way I (we) could use the daemon to build web, email, and even 2 way pager interfaces to the HB... Anyone heard anybody making such developments? Any ideas? Comments? Now it's the time for it... :) 9) That's it :) IC outputs listed below... Thank you very much in advance for any help...

(...) I've heard the difference is that the buttons, the knob and the sensor ports won't work as expected. Try moving pcode_hb.s19 to the directory that contains the dl executable, or to the present working directory, or to the directory specified (...)
