Anyone using these?

[Tem]

Just wondering, since there's only one thread. Are these relatively new product, or totally troublefree?

I wouldn't mind hearing your experiences with these boards.

Hello

These boards are quite new. They all work exactly as specified, and are very good value for money! I guess sales are still quite low because there are not as many different CPU and add on board options as there are for the our MicroX range of  boards. We will eventually also be expanding this range with additional boards, especially for interface converters. If you purchase any of these boards, and are not happy, you can return them within 15 days for a full refund.

Hello Tem,

While I realize that this reply is a bit late, perhaps it will help you in making future purchase decisions.

I am just about finished with a new project using the HC64 main board and am very pleased.

The only thing left to do in my project is to write code to use the RTC.  (Ref: DS1307)

I highly recommend this series!  You would be hard-pressed to find a better value...

Hi JohnD,

Good to hear about your project using this board.

If your project is not commercial sensitivity can you please tell us a bit more,
maybe a few pictures?

Thanks

Hello sk,

Yes, this project is a commercial project. 

I have built my own add-on board mated to the HC-64.
My code is using most of the program memory resident on the 18F6527.
This project uses the RS485 data bus with input data from my propriatary add-on board.
I may be expanding the memory, using the available 24LC512 which I purchased with the board.

This is my first C18 code using Microchip's compiler which I purchased.

OmarZ -> My compiler does not like the BYTE_VAL code in your structure.
              Also, do you have Main.h or Main.c code which makes the calls and defines the BYTE_VAL code.
              There must be a define such as using isdigit to define BYTE_VAL.

Thank you for your replies.   I do plan to release helpful technical information in the future after my code is stable.

Code:

typedef union _BYTE_VAL
{
    struct
    {
        unsigned int b0:1;
        unsigned int b1:1;
        unsigned int b2:1;
        unsigned int b3:1;
        unsigned int b4:1;
        unsigned int b5:1;
        unsigned int b6:1;
        unsigned int b7:1;
    } bits;
    BYTE Val;
} BYTE_VAL;

Thank you OmarZ for code segment (above).

I have searched for, but have not been able to find definitions for BYTE, i2cGetByte(), i2cPutByte(), etc...

These are not in any of the Modtronix i2c.h files I have found.  They are mentioned in several areas on the Modtronix site, however.  I realize I could revert back to the C18 Library routines with different names, however this is quite time consuming if I am going to use the functions you provided for the DS-1307 RTC chip.

Perhaps you could point me in the right direction.

i think you can download webserver code to see how implement i2c functions.

FYI: The definitions were found in websrv65_v306beta2\src\net\i2c.h & i2c.c

Thanks,
