Question first: What is your concern with driving the two steppers? Is it in keeping the two synchronized? Is the issue with having enough power to dr...

@thrandell Please don't spend any more time on my XOR gate question. Too late :) My interest is piqued now. Besides, I came across a major ...

@thrandell I have some code that may work, if you want to double up your encoder frequency. Again watch out for lost ticks if it runs too fast for you...

@robotbuilder If detected by software then the problem of missing a tick I may make it less than ideal to increase the pulse frequency? Yes t...

@thrandell That's it, exactly. Ticks are a distance, with no inherent direction. My SOP is: - set a distance to be traveled (n ticks) - set...

@thrandell I took the cheap and dirty road. I assume that the only way for the robot to move is under power. I know which way the wheels are turning, ...

@huckohio straight lines is the reason I went to PID. I was originally planning to "orient" ARDVARC by running a straight line (a la line following) a...

@byron very interesting. Many thanks. I'll be looking closer at that chip.

@huckohio there seems to be a number of libraries available. I'll try to put a list together, a little later. I'll also be looking at the match betwee...

@huckohio not too much to add. Doubling the encoder frequency is still working well for me, on ARDVARC. The only thing you need to keep an eye on is o...

@henrik_t7, the Arduino IDE is a great tool for most new programmers. It allows you to plow right into writing code for your projects. As you advance ...

I suppose it depends on the extensions you enable in VSC. I have been running PIO and Arduino IDE simultaneously for the past (at least) two years. I'...

Luckily PlatformIO does not steal the Arduino IDE extension (as I remember). No need to disable PIO.There is an issue with installing Arduino, if you ...

@VE1DX, Just gonna toss this into the stream, as I've seen similar way back-in-the-day... any chance that the serial buffer is over flowing? Not sur...

@jfabernathy Yep. We had it easy. When things got out of hand we plugged an HP logic analyzer between the CPU and the board. Then, after programming t...
