Re: What Microcontroller Language do you prefer?

Late entry! :shock:

Given my druthers, I druther program in BASIC. Realistically, I find myself using C. I also look over the assembly for the micro, as well as the Programming Model to get a feel for the micro.

Re: Changing my religion- to linux

Hi again, ... I think i am just too lazy to look into Linux anymore since i have tried them and had too much trouble getting them to work. I guess i would have to ask more questions. This is what keeps me from Linux. I have used TRS-DOS, OS-9, Xenix, MS-DOS, Windows 3.1, 95, XP & XP-Pro, and have N...

DIP EPROMs

When the company I work for moved, I got to raid the dumpster. I have a number of EPROMs from various manufacturers. Most of them are UV-erasable, and most of them have been programmed. The price is roughly 1/2 of what Jameco charges as of this morning, and does NOT include shipping nor handling (pa...

Using used 805x chips

Do any of you use (recycle??) used 805x chips? That is, setting up an external parallel (E)EPROM and the support circuits for your project?

Re: This months Smiley's article

Smiley's article in this months is about makeing a Nav menu in C. He joked in the article saying that some users would probably laugh at his method of using a state machine and a ton of switch statements which made me wonder if theirs a better way to do it, even if it is more complex. There is. I j...

P.S. As an aside- under "Technical Specifications" in the Radio Shack data, "Miscellaneous Features"- "Supported Languages" - English. It's a digital voice recording module! ENGLISH? What, the thing won't work in German? Scheesh. Well, no. IT has a special feature (called "4/1") so it will not work...

Thanks to the both of you!

I suppose most people would not think of looking under "Back Issues" for the current issue, nor "4) Click on the image of the desired issue "

A-mazing!

THanks again,

Downloads -- Where are they hidden?

I am at my wits' end! Many articles in N&V say to visit the website to download code, yet I can not find any way to access said code! Is there a Deep Dark Secret Handshake that is needed? In fact, I can't see any way to contact the owners of the website: any contact button or tab leads me to a subsc...

An "answered" mark would be nice; some way of indicating at what point it was answered would be better, especially if clicking on the icon would bring you to the first answer after "the" answer. A FAQ section would be good, and the first entry to each thread could be links to reference threads, rath...

Topic: Circuit theory to reverse polarity of 12V, <1 amp
Replies: 10

I would use a "electronically-activated bipolar switching device with audio feedback" -- a DPDT relay for polarity selection, and an SPST relay for power control. Set the relay to the polarity you want, then apply power for as long as needed. Use something like a ULN-2003 for the drivers, and stick ...

Actually, the microcontrollers I've used most over the past few years have been Nat Semi's HPC and COP-8. Both are in the "we're only making these 'cause you and some other big companies are ordering millions of them" category. This is at work, of course. At home, I have a slew of 8051s, 8048's and ...

Electronic Frogs. Wow.

A few questions to help me understand what's going on here: When the frog is in a "resting" position -- that is, it is not moving -- what is the voltage between the + and - inputs? And the voltage when it's switching? Does the voltage remain the same after the motion is complete, or does it go to 0?...
