CrystalFontz CFA635 communication

This is a repost since I added it to an old thread that no one looked more...

Someone at - it more on the communication on the CrystalFontz 635 LCD screen? I used their 634 successfully.

I've been watching their 635_WinTest_1.0.exe while I'm trying to reproduce the orders using Visa, but he seems to lack the information (or I'm just not getting it). In their application Wintest, they have a package Viewer but she already formats the data so I do not see the raw format I need to send. I remember on the 634 needed «»

http://www.CrystalFontz.com/product/CFA635-TMF-KU1.html has the PDF on p19 says:

All packages have the following structure:

type is one octet and identifies the type and function of the package:
TTCC cccc
|||| |||| -Response code, error or report command, 0-63
|| -Type:
00 = normal command from the host to the CFA-635
01 = normal reaction of CFA - 635 to host
10 = normal ratio between CFA-635 to host (not in
direct response to a command from the host)
11 = error response to the host (a package of CFA - 635
with the valid structure but illegal content
was received by the CFA-635)

DATA_LENGTH specifies the number of bytes that will follow in the data field. The data_length valid range is from 0 to
22.
the data in the payload of the packet. Each type of package will have a specified data_length and the format of the data as
as well as algorithms for decoding data detailed below.
The CRC is a CRC 16 standard bit of all bytes in the package except the CRC itself. The CRC is sent first LSB. To the
port, the CRC immediately follows the last element used in data []. See ANNEX c: CALCULATION OF
CRC (PG.50) for more details.
he following C definition may be helpful in understanding the structure of the package.
typedef struct
{
unsigned char
command;
unsigned char
DATA_LENGTH;
unsigned char
data [MAX_DATA_LENGTH];
unsigned short
CRC;
} COMMAND_PACKET;

P23

0 (0x00): Ping command
The CFA-635 returns the ping to the host.
Type = 0 x 00 = 010
valid DATA_LENGTH is 0-16
Data [0-(data_length-1)] can be filled with arbitrary data
The return package is identical to the content of the package sent, except that the type will be 0 x 40 (normal, ping):
type = 0x40. 0x00 = 0 x 40 = 6410
DATA_LENGTH = (same as the received packet)
Data [0-(data_length-1)] = (same as the received packet)

Can any that describe the format (1) command that I can start with and build up from there? IE: using LV Visa to a Comm Port.

It would be much appreciated.

I found low level functions of LabView written by Joris Robijn and will try to post them here. They are Open Source license, so I'm not that it will be a problem. His web site is down and they were sent to me directly after doing some extensive Googling.

  • How to tell if someone answered me in the Apple community?

    Hi, I'm new to the community of Apple, and I just asked a few questions here. However, I have not received an email or notifications on all the answers to my messages. I checked my messages manually, then I discovered someone answered me. So, should I manually check my posts to see if anyone responded? What happens if someone answered me on my response to their questions? This seems very awkward for me.

    In addition, I checked my preference, there is no option on the e-mail responses to me.

    You should be automatically 'after' any thread you posted in; If this is not the case, for some reason, make sure to click on the 'monitoring' in the upper right:

    Once you follow the thread, check in your preferences that you have turned on email notifications. Click your name (upper-left), and then click Preferences. Make sure that everything you want to be alerted on is set on "on".

    Make sure yours is on (mine is off):

  • Is there a community Apple Time Machine or Family Tree Maker software by ancestry.com.au?

    I can't find the answer to my posted question, either right now or a few years ago, when I last tried.  Maybe I'm posting in the wrong community.

    My question is as above, because I can not restore a deleted of the software said using Time Machine.

    I could never do all the time when the software was originally installed on my old mac, and I can't do it after the transfer of all my system from the old to the new mac.  However, my new mac now tells me that it can't open the application, although it is on my Dock and works perfectly with some other trees it contains; He asks me to migrate.  He may not need migration because it works!  Any ideas?

    These forums are only on Apple Software and Hardware, so it will not be a forum for any form of third-party software.

    I don't see anything specific to Time Machine, but this Web site provides much useful information about Time Machine:

    http://pondini.org

    Can you explain exactly what you have restored?

    In addition, please explain how the application runs, but doesn't? I'm confused by your statement that it runs from the dock with other trees, but does not otherwise.

    In relation to this, you have restored an older version of the App, hoping that your old trees were stored in the app itself? If so, this isn't how everything works. Apps for does not store data in the application. They have separate data storage areas and that's what should be restored.

  • Why no Community iOS?

    If I missed somehow a 'community of iOS' please excuse me and direct me to it. I can't find a specific questions from the iOS in different research communities. I guess that there are others who also have questions about the operating system itself and not devices, applications etc. It would be a great place to go, for example when Apple released a new version of iOS, to get answers to questions about the stability and features. Or just general questions specific to the operating system. It would be much better than fighting through all the articles / comments that are out there.

    Thank you

    Because the version of iOS for iPhone, iPad and iPod Touch stand out enough that you would always need sub forums for each device. So, what is the point, when you already have forums for devices. There is really no questions on iPhones, iPads and iPod touches that do not address the operating system iOS on them in some form.

    If you have questions about iOS you can post it in the forum for the iOS device to perform on.
