PIC Serial Sniffer

[Kabron]

This is the first version of the serial sniffer (may be Poor man Sniffer is more suitable) I hope it'll be as usefull for all as for me.
The device intersepts all serial trafic between any two devices and transmit it to any terminal @ constant speed (115200).

Features:
AutoBaudDetect in the range of 1200 - 115200
Data direction marking.
ASCI or HEX data presentation.
ANSI terminals support - color data direction indication.
Remember last setting.
No external power, powering from any port.
USB to Serial adapters compatible.

In the next version:
Change to PIC16F88,
More flexible AUTOBAUD,
Serial bootloader,
Ability to direct connection to each of device under monitoring.
May be some data filters...

In attached:
Proton source and hex,
Proteus schematic and simulation projects.

Nice one! It looks like an excellent little tool and would be very useful too.

I see you opted not to use the solder mask then.

What model of PDA is that ?

Does it have a standard serial port on it ?

On the photo it is Fujutsu-Siemens Loox 720, but any PC or PDA with serial port can be used. In case of port absence USB-to-RS232 works fine.

It use PIC hardware serial port for listening and one software(@115200) for transmitting to monitor terminal. All details in attacment.

Well done Kabron, really nice project. A simple to build but very useful tool.

In recognition of your donating this project to the community, we'd like to make the following offer. Send us your files for the PCB layout, and en panels for the D Type connectors and we'll produce and ship to you a prototype PCB free of charge and an Alucase with milled end panels and full colour printing of the end panels and top side.

Contact me for further info on file formats etc.

Thanks a lot Lester for your offer. There are not designs for PCB and panels yet, but I'll make it for the next version with PIC16F88.

How do you find the schematic if you dont have Proteus?

You can download the demo from labcenter

Kabron,


I am getting errors running your software through the ISIS 7.0

When I reply, I will post the errors messages.

I am sure it is something simple.

Thanks for making this Kabron.

Hi, sdrguy. Would you be kind to give some more details. What errors, etc.

Hi, thanks for posting this, it looked useful for a project I'm currently working on so I built one. Unfortunatly mine doesn't seem to work :-( I did make a few changes, I used an FTDI USB UART module for the comms to the PC and it also provides the power to the PIC rather than taking power from the RS232 ports, but that shouldn't make much difference. Can you confirm what it should do on power up? should LED's flash or should some "hello I'm here" text be sent to the PC? Also can you confirm what the fuse settings should be in case I've got them wrong ?

Regards.
Martin.

Hello mfx12
Using FTDI chip is the right solution which i also include in second version of the device. There are not any specific fuse settings and i flash the chip with the attached hex as is with the PICKit2 programmer. Pleas test that XTAL is generating. There are not 22pF capacitors in my schematic and everything works fine, but if your crystal have different parameters it may cause the problem.
After powerup you must see on the terminal(115200) current settings and after sending "h" - some help.
You can also fully simulate and test the device operation in Proteus. Demo version is quite well for it.

Kabron,


Are you still in the process of making the 2nd Generation of Pic Serial Sniffer?

Please inform me/us

Thank you

Hi Karbon,
I want to ask you what is the date of the release of your 2-nd version ComSniffer, i'm waiting it.

Best regards
