Re: What Microcontroller Language do you prefer?

I'm surprised no one has mentioned Forth. I do a lot in assembly and some C on the "big" micros (like the big Arm boards I use). But Forth -- especially cross compiled -- is clean and efficient even on small processors. One of my "hobbies" is building custom CPUs in FPGAs. I have a very novel archit...

Re: Visual basic for linux

If you have the latest Ubuntu/Kubuntu (9.10) look up "quickly" (which is based on Python). Very VB-like. http://arstechnica.com/open-source/news/2009/08/quickly-new-rails-like-rapid-development-tools-for-ubuntu.ars I personally like Gambas.

Re: Ascii Circuit Drawing Program

I guess I like ASCII art because of all the pinups we use to print on the TTYs at our college ham station back in the um... well back in the day. Now as fond as I am of my own ASCIICad, I always thought this was probably the one to beat: http://www.jave.de (Apparently Germany likes ASCII art). They ...

Oh yeah, not ASCII, but my favorite for belting out a quick schematic for an email or whatnot is here:

Re: Ascii Circuit Drawing Program

Well I wrote it to draw schematics on the PIC List (long story) so all the examples are components. Of course, you can use it for anything and since anything you draw can be saved as a symbol.... But if you look at the bottom of the help page: Sample components: cap.txt - Capacitor opamp.txt - Opamp...

I looked at zbasic.net (usually use gcc which is great). Question is, can you use zbasic without the corresponding hardware? Or is it licensed or otherwise locked down to the zbasic hardware?

I don't disagree with anything said. However, consider this. If you have the capability to work with microcontrollers, why not use a cheap micro (like an AVR or a PIC) to do your debouncing and logic probing. You could add things to it like simple logic analysis, frequency counter, signal generation...

Yep its unlocked. Truth be told I liked my old street pilot a little better. The Mio maps seem to have more out of date/errors in them I miss it telling me what side of the street my destination is on. BUT for the money, the feature set is fantastic. The SirfIII chip set is amazing as someone else s...

Mine (a Mio) works fine. Although the speedometer goes crazy. Also it is best if you turn off the option that makes it keep your track on the street.

Personally, I prefer EagleCAD. See www.cadsoftusad.com. Takes a little learning but very powerful.

FreePCB is pretty good too.

Topic: FPGA vs Microcontroller
Replies: 3
Views: 2107

A microcontroller does a series of steps -- usually one at a time -- to complete some task. An FPGA is just a way to wire up logic circuits that "do something". Consider a simple example. Suppose we are working on, say, a rocket engine. We need to monitor 32 sensors and decide if any of two of them ...

I've had good luck with the Dremel with the drill press attachment. A regular drill press probably has too much run out unless you have a better press than I do. The carbide bits are a must. I got an assortment from someone on the Web (might have been Dan's) but I also have noticed $13 for 50 assort...
