Hello Anyone has used a TCP/IP on AVR?? I'm planning to build a system consisting of ATMega128 + external SRAM + RTL 8019. I'm thinking of use "uIP TCP/IP Stack". It will be sending about 200-500 bytes of data to the server on TCP, doing 8 A/C conversion, checking state of <=100 input datalines, and setting ~30 datalines each second. My question is: What will be performance of that system? Will AVR runing at ~15Mhz be able to do all this tasks? Any help will be appreciated Regards Marek Garwolinski SQ4GXO
AVR + Ethernet TCP - performance??

I'm thinking of use "uIP TCP/IP Stack".same here, i just didn't connect the sram,casued by error in chip select... fixed now... bot the project is cancled, due to another HC12 uC(only need transformer and RJ45 externaly) and FPGA http://rapzak.mine.nu (will do some debug on it today)> It will be sending about 200-500 bytes of data to the server on TCP, doing > 8 A/C conversion,you mean by this? checking state of <=100 input datalines, and> setting ~30 datalines each second. > My question is:> What will be performance of that system?

Hi, You may want to have a look at the protocol-on-chip solution by Wizne (see http://www.iinchip.com). The IIM7010A is a piggy-back modul containing the W3100 processor with TCP/IP stack, and the physical 10/10 Ethernet interface plus RJ45 connector. It can be connected to the hos AVR via TWI. This approach saves you a lot of headache, code space development time and licensing questions. Plus the achievable performance is far better compared to a software-onl solution. I used this module on our "AVR Playground" Experimental board (http:/ www.avrcard.com). Regards, Hans This message was sent using the comp.arch.embedded web interface o www.EmbeddedRelated.com
