Update PIC on Minimig

[TheDaddy]

>>Nice to see active people... if I can just get round to getting a shaver power adapter for my MiniMig...



Go on go and buy one, we need more developers (compatibility issues and adf writing), I am as active as I could possibly be with my case design, soon on a desk near you!  :-D

In my understanding VHDL is Verilog. There is also a HDL programming language. Xilinx Webpack can do both.

If you take a closer look to the .zip file, you will find this directory structure:

Minimig-29-05-2008
drwxr-xr-x 2 0 0 4,0K 29. Mai 02:24 build
-rwxr-xr-x 1 0 0  35K 22. Jul 2007  gpl.txt
-rwxr-xr-x 1 0 0  18K 29. Mai 14:03 Jumper.jpg
-rwxr-xr-x 1 0 0  320 29. Mai 14:34 readme_29-05-2008.txt
drwxr-xr-x 2 0 0 4,0K 29. Mai 14:30 source

So you can find the full FPGA sources AND binary inside the zip file.

OT.. but nice little minimig review!!

sorry if you all seen it before, at Retrothing

VHDL is not Verilog, but they are both HDLs.

Ah thanks :-)

[boing4000]

Sorry, there was an error in zip file! Linux zip could unpack it but Winzip or Windows internal function had problems.
Now I fixed it!

Any news on ADF writing and/or compatibility improvements? :-)

[boing4000]

Not by me, sorry. This compiler is too strange for me or I just don´t know the right steps.
Perhaps anyone else did some progress in this matter, it would be fine :-)

Thanks,

I got my minimig (Acube) to communicate with tiny.

Important is, that you press 'check pic' a few times right after you press 'pgm reset'. If i am to late, i get something like:

Connect COM1: ok
  Searching for PIC ...
  pic sending unknown data: "K" <> 2Ah=*
Check baudrate & Start Write while PIC is not sending serial data (e.g. in reset)
  ERROR!

When I am really late, I get:

Searching for PIC ...Not found,
  ERROR!


Proof: terminal window.

Is this a question or a statement?
The new PIC from ACube do have tiny-bootloader. If the timing you mentioned is right, this message will appear:

Code: [Select]


Connected to COM1 at 115200
 Searching for PIC ...
 Found: 18F 252o/452o

Flashing the PIC is already working here.
Handling this HITECH C-Compiler is my problem ;-) But I will not try further because C is really too strange for me.

[yaqube]

I can help you with the HI-TECH compiler. Send me a pm with your problem described.

PS. C isn't strange, it's only simple  :-D

[boing4000]

Thank you, here is the error message:

Code: [Select]


(500) undefined symbols:
        _sprintf (main.obj)_printf (main.obj)
(908) exit status = 1

Right now I don't have the time to learn C. To me it is not as simple as 68k assembly. Verilog is also more like C but more logical to me :-)

[yaqube]

Use STD not PRO edition. I don't know why but in PRO edition you cannot use sprintf and printf together.

[boing4000]

Very interesting! I will try that, thank you :-)
