 | | IC 3.1 Beta4 occasioanlly hangs up Geoport
|
|
Fred, Randy: I noticed that when I use IC 3.1 B4 while I am online (Power MAC 7100/66, Geoport, MACPPP connection) it hangs up (occasionally) the line. It mostly happens if Netscape was used prior to IC invocation. Couple of time it happened in (...) (29 years ago, 23-Feb-96, to lugnet.robotics.handyboard)

There is no recommended way. I've got a pretty simple bipolar H-bridge design that you can connect up pretty easily using an opto isolator and get 3 - 6amps of control and software compatibility. Unfortunately I'm not in the kit business nor do I (...) (29 years ago, 23-Feb-96, to lugnet.robotics.handyboard)

Fred, (et al) Actually I did test to make sure that the LCD was receiving the signal. And indeed it was. I did this before I posted and thought I made it clear. So I guess my problem should have been directed elsewehere since it is not entirely HB (...) (29 years ago, 22-Feb-96, to lugnet.robotics.handyboard)

What is the recommended method for connecting motors that draw over 1Amp. to the L293D chips?? Can this be done at all? -SB (29 years ago, 22-Feb-96, to lugnet.robotics.handyboard)

David -- Soldering d0 to +5v certainly can't help; it should be connected to the data bus (pin 9 of the 6811, pin 11 of the RAM, and pin 3 of the 'hc373). (see the cpu and mem schematic). With board power off, check continuity among these (...) (29 years ago, 22-Feb-96, to lugnet.robotics.handyboard)

(Summary - LCD not reading D0 value) Well the parts finally arrived in the mail for me to start working on my HB.

Dear Mr. Gleason, I gave up to download pcode from my PC (Dell Dimension XPS133c), and I tried to connect the board to Macinctosh (LC475). Then, I could download pcode and the board run well. As Fred's suggestion, the problem was not your board but (...) (29 years ago, 21-Feb-96, to lugnet.robotics.handyboard)

Hi everyone, I've noticed problems with both DL and DLM in certain situations too. At first I used to think that I made a mistake in configuration or ruined a controller somehow.

Hi all, Given Kazuyoshi and other's problems with DLM, if there are any Windows programmers out there who would want to take a stab at a Windows or W'95 implemention, it would be a Good Thing.

Is this OK for getting 6V to motors connected to the L293s? I tapped off the center of the battery back and get about 6V.
