I have removed some standard Forth incompatibilites from FF 5.0
CON was one of those. Maybe it was the only one...

You can always define:

: con constant ;

[Flashforth-devel] FF 5.0 WORDS display

[Pete Z. <pza...@pz...>]

Hi Mikael,

As you may remember, I have had good luck with FF 4.8, MPLAB 8.92 and 
the PIC30F4012 in the past.
Now trying to get ready for FF 5.0 (again with the PIC30F4012).

Is the WORDS display correct in displaying the newly created words at 
the end of your 'kernel'  ?

Am still using MPLAB 8.92 here to assemble/compile and wanted to make 
sure there was no Assembler Memory addressing issue going on.

Do you recommend only using MPLAB X ?

Pete

Re: [Flashforth-devel] compiling for 18F2xK22

[craig b. <dab...@ya...>]

Just got my first chance to test the 5.0 code on my 18F26K22-s and I must admit to being duely impressed.  Tweaked the configs for no idle, cpu usage, or multitasking and full-bore 64Mhz on the intosc.  Popped right up on the treminal at right baud-rate with no arguement.  TICKS  and MS work just fine and TURNKEY behaves as advertised (although the host for these little guys won't want to wait 2 secs if it chucks a hardware reset at them).  Easy config, running code, looks great so far.  I'll load one up with the telemetry slave program tomorrow and torture-test it beside one of the 3.8-based chips tomorrow and see if the BeagleBone can tell them apart (grin).

Seems a first-class piece of work so far, my complements, sir.

Re: [Flashforth-devel] Question to PortB

[Peter J. <pe...@me...>]

The word mclr clears the selected bit. So, bit 0 of TRISB is cleared and 
the dump shows $fe, as it should.

[Flashforth-devel] [RE] Question to PortB

[Thomas B. <bus...@gm...>]

Hi,

ok I see in the dump that the bitmask is twisted

$ff93 -> $fe

but why its that?

Thomas

[Flashforth-devel] Question to PortB

[Thomas B. <bus...@gm...>]

Hallo,

Im a little bit confused about a very simple function. In the ff-tutorial
(flash a LED) the PortB RB0 is set to an output with:

$ff93 constant trisb
1 trisb mclr

thats the bitmask 0000 0001 , but if I look in the datasheet of my
PIC18F2620:

Setting a TRISB bit (= 1) will make the corresponding PORTB
pin an input (i.e., put the corresponding output driver in
a high-impedance mode). Clearing a TRISB bit (= 0)
will make the corresponding PORTB pin an output

Thats confusing me, especially because the forth-program works. What is
wrong in my mind?

Yes, you are missing that the system clock is not counting.

Say TICKS a few times and you'll see that the it is not incrementing.

Re: [Flashforth-devel] strange answer from UART

[Thomas B. <bus...@gm...>]

Hallo, sorry for disturbing - but thats are my further test results:

Freq - OSC - Baud = Status
-------------------------------
16 MHz - HSPPL - 9600 = working
16 MHz - HSPPL - 38400 = working
8 MHz - INTIO67 - 9600 = working (without oszi)
32 MHz - INTIO67 - 9600 = working (without oszi and PPLEnable)
32 MHz - INTIO67 - 38400 = working (without oszi and PPLEnable)

It seems I test the last weekend everytime with a wrong configuration :-)

Thank You all

[craig b. <dab...@ya...>]

... actually, circua line #5204 there's a call ZEROLESS followed by movf Sminus,W,A; iorwf Sminus,W,A; bz MS1... looks odd...

The unmodified source hangs there, too...  Dunnknow, I'm probably missing something.  Didn't take the time to scrape it for side-effects.  I'll look closer after I get the server/client handling on the host BeagleBone figured out (It CAN keep up with the baudrate AND shovel ethernet to the world).

Thanks again for the assist,

Craig,
Probably you have managed to stop the system clock from incrementing the 
ticks
counter. So MS will not work either.

Mike

Re: [Flashforth-devel] compiling for 18F2xK22

[craig b. <dab...@ya...>]

Many thanks, Mike.
Hopefully I'll get time soon to work with the Git-Preview I downloaded and make peace with it (grin).

Meanwhile, the ms word that the turnkey pause calls appears to have an infinite loop.  Turnkey does do its job and not hang if I NOP that "bz ms1" instruction out and re-assemble...  Industrial hot-patch, but effective.

Which wersion of FF do you use? The 5.0 contains the  P18f2x4xk22.cfg file.

Re: [Flashforth-devel] compiling 18F2xK22 FF

[craig b. <dab...@ya...>]

Tne download that I've gotten from SourceForge doesn't appear to have this file (or any mention of the entire 18FxxK22 line other than the 14K22) so I've heavily hacked the beginning of the ff18_usb.asm file to get my 18F26K22-s running.  Unfortunately, when I had to disable the IDLE MODE to get rid of unacceptable system delays, I broke the MS timer call and that nukes TURNKEY.

Can I get a pointer to the xxK22 updates so that I can attempt a polite build without my barbaric thrashings of the code?

Would appreciate it greatly,

P18f2x4xk22.cfg is the device specific file.
You can adapt it according to the used oscillator and other device configuration register options.

Re: [Flashforth-devel] strange answer from UART

[Mikael N. <mik...@pp...>]

Hello !
With the 4 MHz external clock the following should work:

HSPLL , 9600 ,  constant clock=d'16000000'
HSPLL , 38400 ,  constant clock=d'16000000'


FlashForth always configures the internal clock to run at 8 MHz.
With the internal oscillator the following should work.
INTIO67 , 9600, constant clock=d'8000000'

The INTIO67 with PLL requires that the PLL is enabled in software.
There is a define missing in the processor configuration file for that.

The INTIO67 with PLL requires that you define in p18f2525-2620-4525-4620.cfg
;;; Activate 4xPLL from SW for INTOSC modes in FlashForth 5.0
#define PLL ENABLE             ; ENABLE or DISABLE

and then these should also work

INTIO67 , 9600 , constant clock=d'32000000'
INTIO67 , 38400 , constant clock=d'32000000'

Re: [Flashforth-devel] strange answer from UART

[Peter J. <pe...@me...>]

Thomas,
Looking at sections 2.x in the datasheet, it seems to me that the PLL is 
not exclusively for crystals and resonators; it available to the 4 and 
8MHz internal oscillator.  Figure 2.8 shows it limited to these 
options.  That figure is (presumably) a simplified diagram and I don't 
know enough to be sure what would happen if you set OSC=HSPLL and drive 
the OSC1 pin with your external oscillator.  Would you be abusing the 
silicon?  You wouldn't be able to use RA6 as an IO pin but that might be 
OK since you don't show it in use on your diagram.

Re: [Flashforth-devel] strange answer from UART

Dear Peter, is HSPLL actually for crytals and resonators? I use a
oszillator (clock) see link in the first mail. But of course this evening
I'll give it a try.

Re: [Flashforth-devel] strange answer from UART

Can you simply turn on the PLL (OSC = HSPLL) to get a 16MHz sys-clock 
frequency?  I've quite happily run a PIC18F2520 at 38400 baud with a 
4MHz crystal and the PLL active.

Hi,
I think 9600 baud should work.

Re: [Flashforth-devel] strange answer from UART

[Herman A. <exp...@vn...>]

Hi Thomas,

Maybe your problem comes from low Osc-frequency/baudrate ratio. Using 4MHz osc freq. the controller generates the 38400kbs with 10% error. Try to use higher osc freq. or lower baudrate. Otherwise I recommend you to use 18F26K22 or other xxk22 controllers. They have well configurable internal oscillator and have several further excellent features.

[Flashforth-devel] strange answer from UART

[Thomas B. <bus...@gm...>]

Dear Mikael and mailing listeners,

I desperated, I got some strange signs back from the PIC. In my despair - I
installed even MS Windows, to see whether my usb-2-serial adapter is broken
- but the program "Hyperterminal" shows the same results.

Here is my configuration:

PIC18F2620
4 MHz Oscillator Link to
Oszillator<http://www.reichelt.de/Oszillatoren/OSZI-4-000000/3//index.html?ACTION=3&GROUPID=3174&ARTICLE=13706&SHOW=1&OFFSET=500&>
MAX232
FD-USB2Serial-Adapter

The programing - process runs well with my PICKIT2. When the PIC gets power
its send the same strange signs, and if I blind input "1 2 3" (to the
stack) in the terminal, I got a answer - that could be the right one.
--snip--
38400 -  8 - N - 1
¦¬¡³¸¦¯²´¨ •Ž° °©£±˜ Š Š‘
¦¬¡³¸¦¯²´¨ •Ž° °©£±˜ Š Š‘
¦¬¡³¨¦¯²´¸ •Ž° °©£‘¸ Š Š‘
± ² ³ ± ² ³ Ÿ Š
--snip--
Here I restart 3 times the PIC and input "1 2 3" and get back "± ² ³ Ÿ Š".

I changed the baudrate, oszillator frequency, the oscillator selection bits
- without success.
I hope I do some configuration mistakes, so please help me.

The schematics for my hw-configuration, the (binary) log-file of the
terminal and my changed configurations-files you can find here as zip file.

Hi Thomas,
Christmas comes early this year :-)

FlashForth is a 16 bit implementation so ! always stores 16-bits.

: w! ! ;

And Forth is also extensible so here is hex.
