Hello all!

A few years later (life happened), but I can confirm that the 65SPI on the ATF1504 is working flawlessly at 8 MHz as well!

I have implemented it in my homebrew SBC and use SPI for all communication to the outside world (apart from a UART)
It now controls a sound device, WiFi modem, game ...

Found it, thanks!

Hi All!

Well, I converted that CMOS version for CA65 and it actually worked like a charm!
(no surprise there)
Very nice to have a no-IRQ/NMI version with a clean ZeroPage use!

Then I ported it to my full fledged system where I got the original issue and guess what...
AGAIN!

But, I found the ...

Actually, you are both right.
Even though I usually go the path of doing it myself as education, in this case it feels a bit superfluous to do that.
I may aswel write my own version of BASIC...

So, fair enough, I'll see if I can get your CMOS version running on my system.
(I would like to ...

Okay, I switched back to Klaus's original source.

Tested it again on a very basic serial connection and now it seems to behave correctly.
Thus, it might be that my kernal routines do mess up the zero page for EhBasic... *sigh*

Still, I do need some space on the ZP for my kernal, so I must get to ...

Maybe good to know that I went from J.G.Harston's version of EhBasic (2.22p5)

So, the actual program isn't corrupted and still runs normally, correct? It's just LIST that temporarily loses the ability to detokenize properly?

No, the program also fails.
It's not just the LISTing that produces the error.

The example line I gave (580 FOR I=1 TO 12: FOR J=1 TO 12: PRINT P$(I ...

Here is my ehbasic.asm file as-is:

Hi!

Thanks for your quick reply!

It has nothing to do with the Serial connection, as everything works regarding sending and receiving data.
It is also not a speed issue, it happens even when i am sending 1 character a second, so no RTS/CTS of buffer overrun issues.
(I even tried typing it that ...

Hello all,

I am implementing EhBasic on my 65C02 board, and all went well, until...
I hit a snag, of course.


After some testing, I found out that when I types somewhat longer lines of BASIC, weird stuff was happening.
A line like:
580 FOR I=1 TO 12: FOR J=1 TO 12: PRINT P$(I,J);: NEXT J
got ...

Thank you once again, people!
I got it to work.

Was indeed the order in which includes should be.
Thanks.

Hello fellow-coders!

I am using CC65/CA65 to code for my 65C02 machine.
Does anyone of you know if and how i could use Macro's in included files?

Example:
i have a main file that includes another file using:

.include "extrafile.s"

That extrafile.s file uses macro's:

.macro somefunction
bla ...

My pleasure testing it out, Daryl!

I programmed my ATF1504 after reading an Instructable by a guy called Doctek:
https://www.instructables.com/id/Ghetto-Programmable-Logic-CPLD-Development-Syste/

He points towards an easy to build version of Altera's ByteBlaster for old parallel ports, so i ...

In this case that's not a problem at all, since the ARMSID runs on its own (1 MHz) clock, which can be asynchronous
to the other bus signals.

Becoming quite the interesting topic here :)

I see what you mean, Jeff. Clever.
If i was to use this setup, as i understand it,. I would have to add another inverter to the now stretched /RDWR line, as the (ARM)SID normally uses the processors (combined) R/W line directly.
Should not be problematic ...
