Thanks Gavin and REB Yes, I am looking into USB to go above speed limitations of RS232. I didn't know that Atmel had USB-AVRs (AT90USB1287). Thanks! Still, I was hoping to go with a smaller and less expensive AVR like the Mega8. I think it'd be the same deal with trying an Ethern

I think the OP's question was about throughput, which would indicate the speed of RS-232 isn't fast enough. Aren't the FTDI chips still limited to those (RS-232) speeds? David, have you thought about some of the USB AVRs? I bought a couple of USBKEY development boards a while bac

Hi David, I have thought about going into USB comms, but it is really complicated, the easiest solution is to use an FTDI chip and communicates with it through RS232, visit: http://www.ftdichip.com/ Cheers, Gavin --- On Sun, 8/31/08, englsprogeny wrote: From: englsprogeny Subject

I have done projects that implement an RS232 interface. Now I want higher throughput. So...I am looking for a "library" or an AVR-USB driver or some other "something" that I can use to implement USB functionality on an AVR project. I've seen one from ObDev but I want to see if so

I posted my original question there, but I have gotten no response. Is the AVR32 so new that there isn't the community of users out there yet? It looks like the AVR32UC3 will do most anything you want with lots of headroom (MIPS, memory, etc.) and better bang for the buck. I coul

Steve, Interfacing to the keypad isn't a big deal; you can visit our www.pdksolutions.com for an example. However, the largest lcd display I've seen is 40x4; to get 8 lines you'll probably have to go with a graphical module. Again, not a big deal, just a bit more complicated of a

Chris, Have you seen this display: http://crystalfontz.com/products/2002z/index.html ? We get all our LCDs from them and have had wonderful service and quality. BTW, unless you're doing high volume (>10K month), noritake won't bother talking to you. The best place for low volume

2008-08-19 by Zack Widup
First off, what LCD display are you trying to use? Did you find the data sheet for it? Did you try to write a program according to the data sheet? I've succesfully used Optrex 16X2 LCD's for many applications. Pretty simple. I even wrote the code in assembler. Zack On Tue, 19 Aug

I need a programmer for a serial flash data chip such as the AT25/45 or SST25 8pin dip? These chips have an SPI interface. Can I simply use an off the shelf EEPROM programmer? Or perhaps my Kanda ISP programmer? I have few programmers available to me: Kanda ISP (with 5x2) socket.
