hi we developed our own RF protocol based on the free S.N.A.P i think is to big to fit in a pic it was designed to run on avr mega 323 and mega 128 the latter being for a pc link and the 323 used for a handheld monitor unit and a loadcell telemetry unit. it uses a low level hard ware driver so we could drop
I have used this PLM in the past. You can implement snap protocol to communicate the devices. In my case I used a HDLC implementation. Here I have attached a document about snap. Regards. Attachment deleted Look below ... /mikasi
I developed a wireless network to environment monitoring using snap... But I had to do few modifications to improve the performance of the entire system... I´ve chosen snap after looking many others protocols... Let me know your application and I can suggest something more... See ya Rafael
Take a look at the snap protocol (and source code) at HTH's On-Line Catalog - S.N.A.P
some info here : On same site snap protocol and some code exemples.
I want to do a RS485 network, based in snap protocol with PIC'S 16F84A. If somebody know could help with information, I'm agree. Thanks
I do, quite simply, by waiting a certain period of time to allow the line to settle. In my case the network consists of 32 units, all talking asyncronously. Take a look at snap protocol. It's free. I use my own protocol but snap looks good. trace
Have a look at ST7536,ST7537,ST7538 on ST website, you will also find app notes with schematics/source code. HTH have info about the snap protocol, commonly used in these analogue modems. I think ST are the only company left doing analogue modems, most are now looking at dsp based systems for higher data rates. I know ST are
Use RS485 at a physical level and the snap protocol to the application level. ( )
Use a RS485 network with the snap protocol URL HTH's On-Line Catalog - S.N.A.P
There can be S.N.A.P ? Look
Hello. I'm hesitating between the Modbus and the snap protocols. Which one is better and why? I personally prefer snap, because it looks easy to implement and it has lots of examples for BS1 and BS2, which can be easily adapted for Picbasic pro. But as I can see, most of the users in this forum are commenting Modbus. Are there any (...)

Hi The Linux Home Automation project is a bit of a misnomer. It's really meant for use under any Unix like operating system. We already have one gentleman who uses QNX so he'll keep me honest. :wink: I fully intend to keep the source code as portable as possible. And I'm working on getting a *BSD system up and running real soon. The initial inte
