I just wonder if anyone as implemented FlashForth on a dsPIC30F4011?
If not, what would be the necessary change to the source code.
Also, Is there any hardware interfacing diagram avaliable around for the ff4.6 (3012)
Regards

There should be no code changes needed.
Just update the configuration file, select dsPIC4011 in the MPLAB IDE compile and program your chip with
a programmer device (ICD2, pickit2, etc…).
You also need to connect the serial interface via a RS232 (MAX232 chip) to your computers serial port.

The board and PIC chip I have been using is the 16-BIT 28P STARTER DEMO BOARD DM300027 with dsPIC30F4012.
4.6 works well and I will be trying 4.7 on it soon.

Sorry I am not an expert with MPLAB, dsPIC4011 was selected.
MPLAB tells me that "BUILD SUCCEEDED" and that programming also succeeded .
But, there is no sing of activity on any uart port using the RS232 interface (38400, 1, N, XON/XOFF).
Triyng to program the chip with Pickit2 programmer (importing hex file) give me this warning:
"Some configuration words not in hex file…" ??
Thanks helping

Could you please give more information about your RS232 Interface and the actual serial port connection to the 4011?
On my DM300027 Demo Board, I added a Maxim MAX3221 uart chip for the RS232 communications to the U1RX and U1TX pins. I remove the PICkit 2 after programming and make sure the USB Communications is not selected.
I use a PICkit 2 here also and have seen that message but it was not a problem. I have had to program the 4012 twice occasionally and then cycle power with the PICkit 2 removed.
Make sure when compiling that the Alternate I/O selection is correct for your 4011 board.

Normand,
How does your ff30.inc look like ?
Is your oscillator oscillating
To which pins is your RS-232 level converter connected ?
Which linker file did you use ?
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
The exact frequency mesure on osc1 (13) is 15,980,032 Hz . Is this close enough ?
The level converter is a MAXIM max232CPE.
I have tryed pin 26 of dsPic(U1RX) on R2out pin 9 of max converter
and pin 25 of dsPic(U1RX) on T2in pin 10 of max converter
I have also tryed with U2 RX and TX
There was no change made to the original ff30.inc
And the linker file is p30f4011.gld

I just uploaded a new version of FF 4.6.
It has better default values on the configuration file.
- Normal serial I/O pin is default
- Internal FRC*PLL8 is default (58 MHZ clock)
- 38400 baud UART is still default
- Extra DEBUG data is not printed as default

Using the inc file from "pzawaski" give this result on the RS232 monitor:
-FlashForth V4.6 on dsPIC30F

But using the enter key result in an a repetition of the (i) code.
Resetting the dsPIC4011 and typing any character give this message
-a Compile Only
I will download the new version and let you know.

There must be someting wrong somewhere.
Using .equ XTFREQ, 16000000 with "pzawaski" INC file made FlashForth working properly.
To verify the programming procedure used I erased the chip and try to reprogram it with the exact same setup.
After many tries I can't make it work properly ??????????????????

FlashForth is Working perfectly on windows XP with the stadard COM port.
I was working on my portable Midows 7 pro witch have no RS232
It is not working using an RS232 to USB converter .Why ??

This for example one board that you could use.

Use pins 25/26 with setting
.equ USE_ALTERNATE_UART_PINS, 0
At least the baudrate is too high for 16 MHz clock.
Try with 9600 baud.
.equ BAUDRATE, 9600 ; Serial baudrate
Unfortunately the default baudrate configuration is wrong.
I need to fix that.
Here is the core of my .inc file for the 4012…..
This expects an external xtal.
