Announcing the Eleven Development Environment for the MEGA65

ubik · 25. Januar 2021

ELEVEN is a combined editor and preprocessor package which enhances BASIC10 by adding the following features:

- variable declaration

- variable names of arbitrary length
- named labels instead of line numbers
- $ and % prefixes for hexadecimal and binary integers
- easy to read comments
- easy to use 'EE' full screen text editor with preprocessor integration
- automatic backup facility

ELEVEN consists of two main parts: The editor and the preprocessor itself. Both are working hand in hand in order to provide a simple and integrated development workflow.

Example programs and documentation are included

You can download a first alpha version at https://files.mega65.org/?id=8…1e-45a7-a4de-87bcb0b11696

For those of you who don't want to download the pig in the poke, here's the documentation (so far):

ubik : That looks great and interesting!

A very first feedback: You check the ROM version at the start. Be aware that the ROM 911210 has the version index 911203 in $17 to $1C.

So even I use the 911210 ROM I got a warning

What happen if I proceed at me own risk?

If you don't read from me again, my flat will be exploded!

Sadly the editor is not completely usable while working with the Xemu emulator from LGB-Z

The F9 and F11 key are used by the emulator for reset and toogle fullscreen. And a F14 key I'm searching desperately on my keyboard (even then using the Nexys board).

But that's of course no issue of your program. I'll hope that every MEGA65 will have 14 function keys.

Oops, didn't realize that... I'll update the disc image tomorrow, then

911210 is required because the bundled ROM caps the RAM in banks 1 & 2 to $8000 (which of course could easily be worked around, but I think MEGA65 is going to be shipped with a newer bugfixed ROM version anyway)...

Ah, I didn't think of that (as a matter of fact, the MEGA65 has 15 function keys including help)... I'll add alt+g, alt+c and alt+s respectively for those functions in the next revision

(f9 and f14 are not really essential but you'll want to toggle control character mode (f11) once in a while...)

You can change the keymap.cfg of Xemu to make it work. Just look at the keymap-default.cfg file, it is pretty self-explanatory

ubik : I have tried your ELEVEN on the Nexys board. There it works perfect.

I can't use the editor with the xmega65 emulator. The cursor up and down work like a page up and page down (23 lines at once). The xc65 doesn't work at all with the program.

But let me say: I like it very much! It's a great work and a fine piece of software!

Of course I play a little bit with ELEVEN and also modify the "hello" example. I want to add a subroutine ".clearScreen" for clearing the screen at the start:

But I get an error after compiling this source:

My thought was, that I can still use the BASIC 10 commands as usual? Does SCNCLR didn't work or do I have an error in my thoughts?

Many thanks again for your great work! I like it very much!

ubik · 26. Januar 2021

oops again... In order to know which identifiers to try to resolve and which words to leave alone, Eleven keeps a list of reserved words (with the most commonly used commands at the beginning to speed things up). I forgot to add „scnclr“ to that list...

It will be in there in the next version... (in the meantime you can add it yourself in the string rw1$ in line 35 of „11.parse“; be sure to add a space before and after the word, as in the words already there)

Re Xemu: Eleven uses the keyboard modifier scanner at $d611; I suspect that‘s not yet implemented in xemu, so the alt detection would not work. Maybe LGB-Z can shed some light on this...

ubik · 26. Januar 2021

A new version of ELEVEN is now online at

https://files.mega65.org?id=8b…1e-45a7-a4de-87bcb0b11696

Changes:

- adds "alt+g", "alt+c" and "alt+s" for "goto line", "ctrl mode" and "save defaults" commands respectively (thanks, Snoopy)

- adds a whole lot of missing BASIC10 keywords (also thanks, Snoopy :))

- lowers requirement to 911203 (thanks again, Snoopy :D)

It's not possible to type any text in the editor with xmega65. No letter can be typed. The function keys work.

Wow, that's a very fast update delivery!

I'll test it as soon as possible (thanks, ubik ).

Yep, that's a good indication for $d611 not working correctly. If EE thinks that the alt key is pressed all the time, it won't get any regular keypresses.

Just updated to v0.3, get the new version here: https://files.mega65.org?id=8b…1e-45a7-a4de-87bcb0b11696

Changes:

- EE now shows shift+space as 'checkerboard' character (in order to avoid strange compilation errors with illegal shift+spaces)

- EE: fixes bug in autoindent when splitting lines (thanks Alexander)

- adds new example code: "Fieni"

Changing in "11.edit" line 960 in 960 ak=0 let use the editor in xmega65. So it's definitly a issue of xmega65 with the use of address $D611.

Okay, there now is no combined keypress with the ALT key recognized anymore, but at least it is possible to type a text and move the cursor.

I like the editor very much and will not miss it using xmega65!

Edit: Is there a key or command for exiting the editor to BASIC 10 again or do I have to make a reset?

Good point! Next version, then

(in the meantime, you can exit with RUN/STOP+RESTORE, but you should do a BANK128:POKE248,0 afterwards to restore line link mode to the default..., or the BASIC10 editor might behave strangely)

ubik · 28. Januar 2021

Updated to v0.3.1, new version is here: https://files.mega65.org?id=8b…1e-45a7-a4de-87bcb0b11696

Changes:

- EE: new "shift+RUN/STOP" command to quit EE

- adds new sample code "Dizzy" – https://streamable.com/1pfpti

Re Xemu: Eleven uses the keyboard modifier scanner at $d611; I suspect that‘s not yet implemented in xemu, so the alt detection would not work. Maybe LGB-Z can shed some light on this...

The hardware accelerated keyboard scanner (D610-D611) is supported in Xemu. As far as I know without any major problem (till now?). I even use that feature to test programs of mine using D610. So "it should work" as I usually say. In the "next branch" at the download site, there is one little fix recently that key repeating did not worked, but even without this fix it shouldn't cause not even be able to type at all.

hmm, strange... does the following work?

Code

10 bank 128:p=dec("d611")
20 print "please press alt..."
30 do:loop until peek(p)=16
40 print "great! now release it again..."
50 do:loop until peek(p)=0
60 print "noice! thx!"

LGB-Z · 29. Januar 2021

Well, I guess it should work, if you are in VIC-IV I/O mode. Not sure about C65 BASIC it used VIC-III mode only, I guess. Or did you test with ROM variant "forcing" VIC-IV I/O mode?
