Hooray, my HandyBoard works! My kit from DMSC came in on Friday, and I (a very non-hardware guy) managed to assemble it, thanks to Fred Martin's handy assembly guide. I did run into trouble during step 4.4.2 and 4.4.3 (testing/debugging 'serial line (...) (27 years ago, 12-May-97, to lugnet.robotics.handyboard)

I am having trouble using the Vector 2x Compass with my handyboard. I have the compass.asm file and the compass.icb file. I loaded the compass.icb file into the lib_hb.lis file so it would load automatically with IC. When I loaded IC, it said the (...) (27 years ago, 9-May-97, to lugnet.robotics.handyboard)

I *think* rather than /n if you type /m it should be in the second line....I don't remember which letter it is, nor do I have the robotics books near me. Or you can have however many spaces as there are (10? 15?) cursor blanks and leave off the \n (...) (27 years ago, 8-May-97, to lugnet.robotics.handyboard)

(...) A simple way to get rid of the DC component is to run the data through a scrambler on the TX side, and descrambler on the RX side. This has been done successfully in 9600 baud amateur radio TNC's. 2 or 3 chips on each end of the link is all it (...) (27 years ago, 8-May-97, to lugnet.robotics.handyboard)

(...) We did use 900 Mhz Radio Shack RF headphones (cat # 33-1145), which gave us a reasonable analog transmission (the transmitter took L+R RCA audio in, and the we connected in place of the speaker on the receiver). We could get 9600 baud through (...) (27 years ago, 8-May-97, to lugnet.robotics.handyboard)

Howdy, One simple question. Is there a direct way to access the 2nd line of the display. Something like: printf("first line\n"); printf(?????); /* move cursor to second line */ printf("second line\n"); Thanks, Clay Timmons ctimmons@asic.sc.ti.com (27 years ago, 8-May-97, to lugnet.robotics.handyboard)
