Hi Peter,
I noticed that you said you have finished what is already there for the feature set, do you think you will be implementing the Math C_... set. ie.
MATH C_ADD array1(), array2(), array3()
MATH C_SUB array1(), array2(), array3()
MATH C_MUL array1(), array2(), array3()
MATH C_DIV array1(), array2(), array3()
MATH C_AND array1(), array2(), array3()
MATH C_OR array1(), array2(), array3()
MATH C_XOR array1(), array2(), array3()
which I think are quite useful. I've tested the Math slice, that's working fine. Thanks.
Kevin.

Would it be possible to add wildcards to the FAT LS routine?

For Example, I'd like to be able to search for all files that start with the character 4 in the physics directory like this:

fat ls physics/4*

Right now, all I get is file not found. I do get all files in the physics directory with

fat ls physics

Quote If you don't have a RTC and GP27 isn't wired use the PC2 sdcard wiring. If you connect a RTC and GP27 to the 32K output then the firmware will know it is running on a PC3 and you must use its sdcard wiring. You can uses SPI for the SDcard unless you connect and RTC, This was a mistake of mine on the PC2 but MMBasic, MicroPython and now Fuzix work round it using a bitbanged sdcard driver. I don't think this is particularly any slower.
In both the PC2 and PC3 you really should have a RTC as this is used for timestamping files etc.

I added now a RTC and changed the SD card wiring to PC3 - now it works really reliably. My impression was that with the bitbanged SD card access (in PC2 mode), the jumper cable solution was not reliable - but I am also using shorter wires now. In any case, it now recognises the SD card everytime.

One question: It always asks for the bootdev - can this be set to hdb2 by default?

The PGA2350 is a bit less than breadboard friendly, isn't it? :)

... I just saw that networking is now supported ... I can't keep up.
Now I have to add another breakout board to my contraption

V0.19 is now available
https://github.com/UKTailwind/FUZIX/releases/tag/pc3-v0.19
This has networking support for the PC3 and various internal changes. In addition it has requested items: Boots direct to the login prompt, c_NNN math commands added. FAT commands accept wildcards

For breadboard use with the PGA2350 I installed the row of pins with things like USB pointing down and the rest pointing up. That way you can plug it into the breadboard for stability but have access to all the pins

Thanks Peter, I've tried a couple of the Math C_... functions and they seem to be working great, thank you. :-)
If you are interested you can now slightly speed up bubble, by using Slice
comment out this line
' If Not(g Mod 10) Then n(j)=m(g\10,j)'copy from colour map
and add the Slice just below the commented line
'Memory unpack Peek(varaddr m(0,g)),nn,100,32 'unpack pixel colours
Array Slice m(),g\10,,n()

There is something strange happening with the frame time readout in the top left corner, it almost looks like it's being printed twice at different sizes?
Regards Kevin.

Please list the exact program you are testing with

V0.20 is now available
https://github.com/UKTailwind/FUZIX/releases/tag/pc3-v0.20

This implements the MMbasic compiler hooks into the web functionality so that now standard MMbasic WebMite functionality is available. To prove this I have tested Geoff's watering controller

This means in Fuzix the MMbasic compiler has now been tested with:
PicoFrog
Petscii Robots
Solar_Eclipse
Bubble Universe and other graphics demos
Reticulation controller
Various benchmarks
and dozens of test programs for specific functionality

We are therefore now in the state that, other than very specific functionality, anything that runs on interpreted MMbasic should run on the compiler subject to nothing more than trivial modifications

Thanks for v0.20!
One questions: Is there a way to access "/dev/tty2" from MMBasic?

Thanks

Never mind - found it.

Open "/dev/tty2" For Output As #5
Print #5, "Hello from MMBasic"
Close #5
End

Hi Peter

Transferring files from and to FUZIX is currently awkward - is there a different solution other than serial to be expected? A partition on the SD card that’s is readable and writable from FUSIX?

Thanks
Thomas

Well, that's half of what he wanted anyway. Any plans to make the FAT partition writable as well?

Yes, in both directions - as on the PC

Fun with processes:
test.bas:

Dim Integer i
Print "text.bas: Starting ..."
For i=0 to 9
Open "/tmp/signal.txt" For Output As #5
Print #5, i mod 2
Close #5
Print "test.bas: Updated signal"
Pause 2000
Next
Print "test.bas: Done"
End

rec.bas:

Dim Integer j, i = -1
Dim String s$
Print "rec.bas: Starting ..."
Do
Open "/tmp/signal.txt" For Input As #4
Line Input #4, s$
'Print "rec.bas: `";s$;"`"
Close #4
j = Val(Mid$(s$, 2, 1))
if j <> i Then
i = j
Print "rec.bas: New state (";i;")"
EndIf
Pause 100
Loop While 1

Output:

# ./rec.bc &
rec.bas: Starting ...
rec.bas: New state ( 1)
180
# ./test.bc &
text.bas: Starting ...
test.bas: Updated signal
rec.bas: New state ( 0)
181
# test.bas: Updated signal
rec.bas: New state ( 1)
test.bas: Updated signal
rec.bas: New state ( 0)
test.bas: Updated signal
rec.bas: New state ( 1)
test.bas: Updated signal
rec.bas: New state ( 0)
test.bas: Updated signal
rec.bas: New state ( 1)
test.bas: Updated signal
rec.bas: New state ( 0)
test.bas: Updated signal
rec.bas: New state ( 1)
test.bas: Updated signal
rec.bas: New state ( 0)
test.bas: Updated signal
rec.bas: New state ( 1)
test.bas: Done
