I have a procedure that collects some data in a loop, and then sends that data
out the selected port. The data is standard ASCII with a leading STX character
and a closing ETX character. The port is either one of the serial ports or the
ethernet port. If the ethernet port is used, a CR/LF pair is added after the
ETX.
I haven't experienced any problems when using the serial ports. But when I use
the ethernet port, I don't get the full message. If I run the code under the
debugger, it won't fail. If I add a printf statement to send debug data out
another serial port, the problem won't manifest it self either. If I just format
a string using sprintf, and then throw the string away, the procedure works
fine. The ethernet connection is TCP/IP.
Does anyone have any other ideas on how I might troubleshoot this?
I'm using DC 9.25.

Hello,

I have a code that I need to modify.

the code runs on a rabbit 2200 module with ethernet.
it is a website that read some data from the board and transmit it to the
website.


I have there a const HttpSpec array called http_flashspec[] that is initialized
with many lines such as the following:

const HttpSpec http_flashspec[] =
{
  {HTTPSPEC_FILE,"/",index_html,  NULL, 0, NULL, NULL},
  {HTTPSPEC_FILE,"/index.html",index_html,  NULL, 0, NULL, NULL},
  {HTTPSPEC_FILE,"/SetIPpar.shtml",SetIPPar_shtml, NULL, 0, NULL, spr}
.
.
.
};

and more lines.

the problem I have is with the last line that has the spr var at at the end.

the spr is a variable of type "ServerPermissions", that should popup a
authentication popup before opening the "SetIpPar" page.
it used to be a "httprealm" variable because this software was compiled in a
7.25 dynamic C version. I was asked to modify the software so it can be compiled
in a 9.62 dynamic C compiler due to a problem that occured in that software when
they compiled it in the 7.25 ver.

so I saw that I need to change the httprealm to a ServerPermission in order to
adjust the software to the 9.62 compiler.

when I try to compile this I get an error:
"constant initializer expected"
and it points to the NULL before the spr var in that line.


I must mention that this is the first time I deal with a tcpip rabbit. (I have
many years of experience with rabbit 2020 with no TCPIP on it.)

can anybody see what is my mistake here? or give me a link to read more about
how to make the modification I want to do?

thanks in advanced.

Hi!

I have data being sent from a VB.net application via bluetooth to an RCM3100
with an eb506 module. The data is being echoed to the debug port, so I know that
the correct data is being received. What I would now like to do is, if the data
is correct in the debug window, redirect the data to be used in a decision
statement.

For example:
If the data in the debug port reads "ON", activate some pin high or low?

Can anyone assist with this?

Hi.

I would like to know if someone has ever made any board that could be used to
plug into what is the LCD header on the BL2100 for use as a 16 bit AD.  If so,
how many AD does it have (best if there is 2).  I would like to see if I can buy
this.

If not, depending on cost, is anyone interested in seeing if this is possible
for design etc?

Thanks.

Hi,

I'm designing a carrier board for a RCM5750 and am working from the RCM5700 Interface Board Schematic from Rabbit. I just noticed that the TX+ and TX- signals from the RJ45 jack (with integrated magnetics) go to the TX- and TX+ (flipped) on the Rabbit module in the schematic. I've been trying to examine the actual interface board but since it's surface mount with teeny tiny traces and small value resistors I'm not having much luck with either a multimeter or my eyes (with magnification). The RX+ and RX- go to their respective ports on the module (plus to plus and minus to minus). Just seems odd that the RX plus and minus match up but the TX plus and minus do not. Maybe since the signals are going through transformers (within the jack) it doesn't matter?

Thanks!

-- Jeff

I noticed this too when recently laying a board for RCM5700
Other documents from Rabbit show TX+ and TX- going to the pins you'd expect.

I did some experimenting and discovered that it's probably a mistake in the
drawing. In my design I connected TX+ to TX+ and TX- to TX- and it works
perfectly.

Please remember that you need to pull the ACT signalto +3v3 via 1K (and  led if
required) and the LINK light down to gnd via 1K (+led) or the PHY will come up
with the wrong address and wont work.

I would like to know how to place an xmem function with an absolute address? I'm
using DC 10.54 and an RCM5700. I tried #xcodorg but it gives:
line  353 : ERROR BOOTMANAGER.C   : "??????????" is deprecated.  Please
use "?`?`?`??" instead.
Don't have a clue what to use instead. lol

Thanks in advance.

On reset, the PHY chip used in the RCM57xx family samples the LED signals as
inputs to set the internal PHY address, then switches them to outputs.  That is
why the documented design for the RCM57xx Ethernet circuit (Tech Note 266) has
the 1K resistors on the ACT and LINK signals, and why we recommend that
customers follow our designs :v)  All you really need are the appropriate
pullup/downs on those two lines if you don't want actual LEDs.

That said, we _really_ should have documented that particular PHY functionality
since it is quite non-intuitive.  I've submitted documentation updates for the
RCM5700 User's Manual and TN266 already.

Hi Millar,

Yea, sorry I forgot mention the details,

I using RCM 4300 Development board,
So far I have tried and follow the sample from rabbit web documentation
And I have solved my problem (please see my code below: ZHTML CODE and C-CODE),
thanks for your respond.

But I have another problem,

Let say, the "led1" state on board is "ON" (bit PB.2=0) but on the web page (for
the first time access) there is no radio button checked, of course this is wrong
information for user.
So, I want the "form" lookup hardware condition first and then set which one
radio button should be checked.

Sorry if my English not well, can you help me how to do this?

Thanks.

Good call on the Grounding Issue!   I only had RX and TX from the rabbit to a
DB9 to a db9 to USB converter.  As soon as I attached pin 5 of the db9 to a
rabbit ground all is well.  That was exactly what the issue was.

I was fooled because of two reasons:

1) The DIAG port connects to the PC on its own USB connection, I would of
expected the other USB to be a floating ground regardless of the DIAG port
arrangement.

2) The documentation in STDIO_SERIAL.C /DC 10.56 for the Rabbit 4000 processors
expressly says you shouldn't use serial port A, so I jumped to the conclusion
that that is where the problem laid.

Meantime, so why does STDIO_SERIAL.C /DC 10.56/ rabbit 4000  say you can't use
serial port A?   It seems to work fine for me...

If I completely disconnect the Diag port connector so I don't have a connection to serial port A, it looks like the transmission portion of serial E is not working. My timed TX message that goes out on serial E is not being received by its hyper-terminal session unless I plug the 10-pin DIAG connector back into the 10-pin J1 header. I don't know if the receive portion of serial E is broken or not, and I know nothing of serial port F. It does appear that the rs485 port on Serial C TX is working and is not affected by serial port A 

I just spent 10 days and a few hundred quid trying to figure out why my Ethernet
interface wouldn't work on a board I designed for the RCM5700

Turns out that you HAVE to implement the ACT and LINK leds before the interface
will work - no idea why.

The ACT led must be connected from the ACT pin via 1K resistor then LED to +3v3

The LINK led must be connected from the LINK pin via 1K resistor then LED to
ground.

Any other combination and the interface won't come up!

Hi all. I am new to using rabbit controllers and I tried to post here before,
but I couldnā€™t find my post a few days later. I must have done it wrong.
Anyhow, Iā€™m working with a rabbit 3000 micro on an RCM3720 development board,
a GPS and satellite modem. Itā€™s a tracking device of sorts. I have the GPS
parsing lat/long to the STDIO window and am now trying to send this information
to the modem.

The modem is an Axonn STX2. Communication to it is by an asynchronous serial
bus, 9600bps, 8 bit, no parity, 1 stop. My serial comms experience is limited at
best and this is the first time I have used a rabbit micro, I usually use atmel
ones. So I have a few questions regarding this:

I will be sending 14 bytes to it via the serial port in hex format, I was
looking at using a ā€œchar stringā€ for this and loading the hex straight in.
Is that possible?
IE: char teststring [15] = 0XAA0100010203040506070809C0C0

Next I wondering how to send this to the modems UART from the rabbit.  Do I send
it character by character from the string?
IE:  Using a for loop, sending teststring[0], then teststring[1] ā€¦ā€¦ā€¦
teststring[14]

Or can I load it into a buffer in one hit and send it out in one go?  How would
I achieve this?

Any advice would help immensely, due to my ineptness using this micro (and in
general). Thanks, Glen.

For clarification, when I talk about the 10-pin J1 header I'm talking about the
target for the 10-pin PROG connector or the 10-pin DIAG connector.

It is documented that the  BL4S200 won't let me use the serial port A port as a
redirect for the stdio window as per the instruction detailed in
Samples/STDIO_SERIAL.C of the DC 10.56.That program wants me to redirect stdio
window to serial E or serial F.  Unfortunately, both of those ports are in use
for my application.

In the other single computer board I've tested the BL2600, I was allowed to use
the serial port A as per its stdio_serial.c program in the DC 9.62 samples
directory.  Using the following code:

#define STDIO_DEBUG_SERIAL SADR     //for run mode and the Diag port!!!
#define STDIO_DEBUG_BAUD  115200

By accident, I left these lines in my code when I ported over my program to the
BL4s200, and was pleasantly surprised that it did work, I was able to use the
serial port A in run mode, but here's the issue:

If I completely disconnect the Diag port connector so I don't have a connection
to serial port A, it looks like the transmission portion of serial E is not
working.   My timed TX message that goes out on serial E is not being received
by its hyper-terminal session unless I plug the 10-pin DIAG connector back into
the 10-pin J1 header.  I don't know if the receive portion of serial E is broken
or not, and I know nothing of serial port F.  It does appear that the rs485 port
on Serial C TX is working and is not affected by serial port A

I realize this is not documented functionality of the Serial port A, and it is
documented that I am not allowed to use the Serial port A on the BL4S200, but I
think we are just a lib fix away from getting it to work (very similar to the
previous issue we had with the serial ports interfering with each other.)  I'm
hoping that the engineers that were able to fix the dependency issues with the
ports can do something here as well.

The point is, it seems serial port A does in fact work, and the only issue is
that is can't suspend if for whatever reason if it does not see a connection on
the 10-pin J1 header.  For that matter, if I had a flag that I could check to
see if port A is either: 1) in debug mode, 2) in run mode but not connected or
3) in run mode but connected.  I think that is an effective workaround.

Alternately, if someone can tell me what is required to simulate a connection on
the 10-pin Diag connector I could work with that.  I've tested the program with
a hooked up cable to a pc with no software running to talk to serial port A,
(aka, I don't have a hyper-terminal session active )  and the I/O on serial port
E seems to be ok. This leads me to believe that this is a simple hardware issue
check for voltage on one of the pins of the 10-pin DIAG connector (RTS/CTS
high???) so If I put some circuitry between the 10-pin J1 header and the 10-pin
PROG/DIAG cable that supplied xxx voltage to pin yyy if there is none detected
on the real 10-pin DIAG connector that would work.  I hope I explained that ok.

My guess is that serial port A is using RTS, CTS in some fashion, and as a
result this makes for higgly-piggly (that's a technical term) when there is a
disconnect.  All I want is that TX fall to the floor (and any RX to go
unanswered).  If I could check a flag for RTS, CTS (or whatever is present if
and only if there is connectivity on the 10-pin J1 header) I can use that to
programmatically not use STDIO.

Ok, the serXrdUsed() was an ~~OK~~ workaround, as I no longer waited
indefinitely, but while one serial port was reading the other was still
suspended.

I spoke to Rabbit support about this and there is definitely an issue with their
library about it.  The were very helpful and have supplied me with an updated
RS232.LIB that resolves the issue.

Hi,

Some of my latest designs use the RCM5700 which has a 1M Flash
The program itself is pretty small, but it would be great if I could store the
system configuration in an unused portion of the 1M Flash - this would save me
having to add a serial flash to the board.

The whole data set I'm trying to save is less than 64K in size and very rarely
changes (so no write cycle worries).

I've seen some chatter on this group recently regarding reserving space in the
flash - but I didn't quite follow it all.

Is there anyway to use the unused areas of the 1M flash for this purpose?

I know I could use the 'user block' but it is only about 8K in size, and it
seems a waste to have all that extra flash memory just sitting about doing
nothing.

Thanks for the info. I just got an email telling me the RCM5750 and RCM5760 will
be coming soon. They both support RPU.

I'm wondering if anyone has developed a method of upgrading the firmware in the field through Ethernet on the RCM5700? 
Since the devices my company supplies are used outdoors and often at remote sites throughout the world, the RFU is not a reasonable solution for upgrading the firmware.
Just looking for what other people may have done to solve this problem.
