Hi AllyCat,
I can see there is a big gap in my knowledge. I did find a similar data sheet, but that is for the display, and I cannot make head or tail of it
I am interfacing via the firmware chip on the AXE 234, using those 254, xxx commands. I cannot see how to relate the information on that data sheet to a three digit decimal number to put in those commands.
As I mentioned, there is a short list in section 3 of the manuals, and a different set on the AXE134 data sheet.
Merging the two gives me a slightly longer list, even a couple where Slightly different functions are described for the the same instruction number.
Certainly that 8 digit gap is upsetting, as in transmitting the ppp_filename inserted by the preprocessor, I don’t see that there is much I can do to edit it to display without those gaps. I am wondering what Hemi does about that.
But most puzzling was that following a suitable delay to read what I could see, sending the 254,1 command did seem to clear the display as described, but further commands to select a cursor start point did not result in the expected result and often data appeared to be at least partly in that 8 character gap so could not be seen.
One of the tables (p.41 of section 3) says 254,1 clears display and moves the display window to position 1, the other (AXE134 data sheet) says it just clears the display and 254,2 then moves the window and cursor to the start of the first line. While both lists offer 254,128 to move to the start of the first line. I believe I tried all the combinations.
At this stage I am becoming resigned to having to resort to 20 character limit on file names. At least it is a little better than the early DOS 8.3 limit - just when I was starting to enjoy the freedom of the longer file names!
However, you have prompted me to have another look at that data sheet, and I have thought of looking back at the AXE133 code text document and I am starting to see how to find some of the instructions, but most are pretty mysterious. Perhaps, in reality, I don’t need more than listed those in the the two documents I am referring to. I just need an instruction number, or sequence of instructions to clear display, reset to position one, and restore left to right writing After scrolling.
I am really trying to avoid doing anything difficult, but still thinking.
Thank you
