Hi Stefan, that looks very nice but do you know of something comparable for analog signals? I mean google will find plenty of selection and I know about http://www.bitscope.com/ but if someone has first hand experience with an analog/digital scope I'd like to hear about it. Sande

Ditto with respect to both AVRFreaks and the Mega3290. I did find the forum name to be a bit of a hurdle to get over, with overtones of hackerdom an all. But there are both hobby people and professional engineers there. It gets slightly wild at times (compiler wars, c vs asm vs a

Re: ez430 You keep the USB dongle connected to the MCU board and use it as one, I think there are maybe 4 I/O pins you can use on the small MCU board, you should check what kind. Cool thing is that you get another wireless MCU board so your sensor can be wireless :-D ------------

I just saw that their larger device doesn't do analog. That's a bummer. It would have been pretty spectacular to have a 75 MHz analog scope for $275 :) Thanks for the ant reference. Looks like you can't get it anymore but the newer units are also quite reasonable. http://www.bugb

What's the resolution on your logic analyzer? The other thing would be to look at how the time delay is implemented.

Hi Jeff, Thanks that's an interesting pointer. Advantage is that its ready made and basically plug&play. Then again that's it's drawback too. It's closed and I possibly can't reprogram it or add stuff like my temp & humidity sensor. And it doesn't have the 'I made this' factor. ;

I have used the FTDI FT232 part and nothing could be easier. You give it TTL serial data, it spews out over USB, and vice versa. Out of the box with no configuration or setup, it runs at only 9600 bps. You can add config memory and set it up for higher speeds. I'd highly recomend

There are a number of factors that determine the RS232's max speed [including cable length and processor clock speed]. I think I've seen that RS232 can get up to 230.4K baud. It's interesting what you said about the FTDI interface's top speed. I wonder if it's because you aren't
