I second (or third) the motion for Arduino. Not only are they cheap, but there's a ton of user-created software libraries for every possible I/O device you can name,...
I'm more than a little surprised that no one has given you the obvious answer: GET AN ARDUINO UNO.They're cheap ... under $12 on Amazon, and under $5 for Arduino...
Ok, this changes EVERYTHING. If I understand you correctly, the transformer was buzzing even with no load connected to it. Then the circuit worked for a couple of...
I'm a little surprised that the design requires so many different voltages. I've never heard of a design needing two different HV supplies. I'm also confused that...
Kocsonya has reminded me that the 68000 used two stacks, the User stack and the Supervisor stack. This let folks writing operating systems separate user space...
Ok, thanks for the reminder. I must admit, I had forgotten about the User vs. Supervisor mode. Thanks for reminding me.One of the things I really admired about...
I'm a simple man, so I'm going to give you a simple answer: THERE IS ONLY ONE STACK.I see that other folks disagree, and that's OK. Apparently there are "odd" CPUs...
Jim, thanks so much for the extra details. I see that you & I have been down many of the same roads.I'm still a little confused about the dates, though. Are...
Jim, like you I'm a "seasoned" computer guy. Like you, I started writing code long before C was available. But I'm puzzled by your comment that you had to write...
Hi, ani! I've read your inquiry and the replies, and have a couple of bits of advice. Some of this is going to rub other folks the wrong way, and I apologize in...
Re: Is it reliable to use a macro to change the value of a global variable to be more readable in C?
Yep, it used to be almost the model for a "good" Fortran program, back in the day. And you're right: The excuse is usually performance. Thankfully, computer scientists...
Re: Is it reliable to use a macro to change the value of a global variable to be more readable in C?
I agree with bamos. You can't create a C++ class in C, but you can do the next best thing by putting the data item and the functions that operate on it in a separate...
Donvoth, you said "The harmonics are an integral part of the original signal."That sounds wrong to me. I thought you were building a tuner to let you tune the guitar...
If you are getting such strong second harmonics, it could be because the signal itself is highly nonlinear. Have you looked at the signal on a scope?Also, most...
No, the Arduino IDE _DOES_ use C++. It just doesn't look like it because the general structure -- the setup() and loop() functions. plus most of the built-in library...
Hi. I'm in pretty much the same situation. Was programming 8080's -- and even 4040's -- back in 1975, for use in embedded systems. I did a _LOT_ of software and...
Can't claim to be an expert; Like you I'm just getting into FPGAs, and for the same reasons. But I've ordered an Elbert V2, which has the Xilinx Spartan 3A chip:https://www.amazon.com/Numato-Lab-Elbert-V2-Develo...It's...
I guess I'll lose this competition because I'm not going to try to answer the question directly, but talk in more general terms.First of all, I reject any notion...
