Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Hi folks,

Well alpha 1 is ready and available for x86_64 and Raspberry Pi (armv7l):

   https://github.com/thwill1000/MMB4L

I imagine there may be some teething troubles whilst we get the correct distributions built and installed.

I'd appreciate it if you would let me know how you get on, please keep all MMB4L correspondence to this thread.

EDIT: I can't promise to be as responsive as Peter is though.

Best wishes,

Tom

Excellent. Any hope for Armv6 as on the zero and zero-w or should what you put on github work?

Hi @lizby,

I'm not certain, but I think the 'armv7l' build "may just work" (TM), as when I was looking at the #defines the compiler was setting they all seemed to be ARM 6 rather than ARM 7 . Anyway would you mind giving it a go, and if it doesn't work then I'll dust off (literally) a Pi zero over the weekend and build a specific version for that.

Best wishes,

Tom

Hi Tom,

Will it run on any 64 bit linux that has nano editor available ? Or is this specific *BUNTU for the moment ? All my machines are 32 bit linux, and I could try to boot a live distro to test this out (some of the CPU's have 64bit , but I installed 32 bit to stay common over all machines).

Thanks for the answer...

Very nice! Is there a way to return to the Bash prompt? I didn't see one in the README.

Hi @Volhout,

I'm not 100% certain but I don't think the build is Ubuntu/Debian specific. I guess there might be an issue if the Linux distribution has too old a C runtime but I believe Linux is pretty resilient to that sort of thing (more so than Windoze).

I guess I will be dusting off my old 32-bit DELL Lubuntu laptop over the weekend too then .

You've got a Chromebook too haven't you, are you running Crostini, in which case what does "uname -a" have to say for itself.

Best wishes,

Tom

As a data-point the x86_64 build doesn't run on CentOS 7 (but looks like it would on CentOS 8) because it needs GLIBC_2.29.

Hi Tom,

I will try tomorrow on a newer live distro.

The one 64bit machine I have throws an error:

mmbasic: /lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.29' not found (required by mmbasic)


Guess this machine is too old... (Xubuntu 18:04)

I have uploaded an x86_64 build with a lower requirement (GLIBC_2.14):

   https://github.com/thwill1000/MMB4L/blob/main/binaries/mmb4l-2021.01.00-a1-x86_64-glibc-2.14.tgz

GLIBC's are supposedly backward compatible.

Best wishes,

Tom

This is a kludge pending incorporation of pin I/O into the firmware (if that happens), but here is

Digital output to pins on a Pi Zero W with MMB4L:

Youtube: LEDs on and off

' PiIO.bas performs digital I/O with linux4MMB
'
dim integer i,j,k,p(16)=(0,26,19,13,6,5,0,11,9,10,17,22,27,12,16,20,21)
dim integer pState(16)
dim integer q(4)=(0,14,15,18,23), dout=1, din=0

for i=1 to 16
 setpin p(i),dout
next
for i=1 to 4
 setpin p(i),din
next

i=1
do
 pState(i)=1-pState(i) ' toggle state
 cmd$="sudo echo '"+str$(pState(i))+"' > /sys/class/gpio/gpio"+str$(p(i))+"/value"
'  print cmd$
 system(cmd$)
 inc i: if i > 16 then i=1
 pause 500
loop

sub setpin(pinno as integer, pinmode as integer)
 local string dirname$, cmd$
 dirname$="/sys/class/gpio/gpio"+str$(pinno)
 if not MM.INFO(EXISTS DIR dirname$) then
   cmd$="sudo echo '"+str$(pinno)+"' > /sys/class/gpio/export 2>/dev/null"
'    print cmd$
   system cmd$
 endif
 if pinmode then
   cmd$="sudo echo 'out' > "+dirname$
 else
   cmd$="sudo echo 'in' > "+dirname$
 endif
end sub


A minor point: artifacts in screen when up-arrow to re-run command (but very happy to have that feature):

> edit
run
> redit
ererun                                                                        
> redit
erun                                                                          


This uses BigMik's freeware 2x20 breakout Proto Board.

Congratulations, Thwill. Nice work. I look forward to exploring.

Loaded into Mint 20.2 and working.

Have nano working (v4.8) and can edit/save etc. but am a little confused with the instructions on using nano?

Great job Tom, looking forward to following developments.

It's functional, it's just not useful .

My understanding is that on the other 'mites (except CMM2) the current program is always stored (in the flash) in the tokenized form and this option controls how it is converted back into ASCII when the user EDITs or LISTs it.

MMB4L and the CMM2 work differently in that they always EDIT and LIST the disk file, not the program stored in "flash".

If you want to see what is in the "flash" type LIST FLASH and the keywords displayed will respect OPTION CASE. However note that irrespective of OPTION CASE all the variable names will be in upper-case, I don't think this happens with the other 'mites, it is probably an optimisation by Peter that MMB4L has inherited from the CMM2 code.

In the future my intention is to throw away the somewhat adhoc preprocessor inherited from the CMM2 and replace it with one based on my own SPTools preprocessor. This will allow me to add proper pretty-printing / re-formatting to the language.

Best wishes,

Tom

Right, I changed my mind a number of times about which should be which.

Should I correct the nano resource file? or should I correct the README ?

You can of course edit the nanorc file to personalise it for yourself.

Tom

Impressive, I'll have to find time to give that a go.

  lizby said  This is a kludge pending incorporation of pin I/O into the firmware (if that happens ...


It is my intention (at @robert.rozee's suggestion) to look into doing this with the pigpio library when I find some more time; I need to take a bit of a break now as I've been neglecting other things to get MMB4L out there. This is I believe a higher-level approach to what Peter did with the PiCRomite so may perhaps not run into the same issues. When I come to it I may need some hand-holding on the hardware/electronics side.

I can't reproduce that on my Ubuntu build, what is the program that you are running ? It may perhaps be "messing" with the interpreter's concept of the current character position.
