Motor Mind project failing PLS explain

edited 2005-05-18 00:12 in General Discussion
My motor mind c board appears·to not·work.· The problem is that the TM (BS2 serial data to motor mind·c) and (FM motor mind c serial data to BS2).· TM works sending data, but the FM doesn't send back data.· If anyone can tell maybe why this is the case.

The code I use is the code is the datasheet (figure 6)which I·have changed just one part (IF IN14 = 1 THEN .........) to (IF IN7 = 1 THEN...........),· but motor mind still doesn't send data.

Maybe some·code is missing from the program?

    It will be much easier for members to help you if you post your code.

    Just upload the code you're opening in your editor. I'm sure the code in the docs is fine -- it's what's in your editor that has the problem. And do everyone a favor and upload it as a text file -- that way it can be viewed online.

    One problem I saw in Part 1 is that you're declaring a BS2p, but using the Baudmode parameter value·for the BS2 -- they are not the same and this will cause a communication issue. For the BS2p, the baudmode value for 38400 baud is 45.

    Time to use your template file with all the nifty definitions?

    I considered posting it with my response ... but, tragically, I seem to be the only one interested is taking advantage of conditional compilation....

    Perhaps the next IDE could have a check box option when creating a new file to insert commonly used conditional compilation definitions. I find most people's poor coding style is due either to inexperience or laziness. If a programmer could automatically incorporate the template via checking a box I think both of these classes of programmers would be more likely to adopt the practice. An ideal implemetation would have the template in a plain text file that the experienced programmer could edit to provide a custom template for thier own use.

    Hey Jon, I use your template all the time. I use three different stamps often and occasionally a fourth so it really comes in handy. But that's a good idea - how bout making it built into the editor!

    It can be -- you can set a file to use any time you select File\New. It's all done in the Preferences dialog.

    baud rate is not the issue stop. The code as I am using it with CON 84 debugs (setdc error) and sometimes turns the motor very slowly read the code I gave you again and use baud 84 with CARRIER BROAD REV3-MMC CONTROLLER REV4 (THE ONE WITHOUT THE HEATSINK)

    I have solved the issues I have had with MMC and I'm using a simply code, but still can't get AN700 to work

    Thank you all
