Re: One more time...controlling multiples motors with raspberry 3

Yes you can achieve your goal with a single RPi, you will need some external HW in between (mostly drivers, I recommend ULN2803's, and some form of buffers with enable lines to allow you to select sets on output), use PWM, and external power supply, and it is fairly simple to wire up. Just remember ...

I am strongly apposed to cloud based solutions, especially with patient critical information (like you are speaking).

Re: Can Anyone Suggest a desktop Linux for RPi

Once you do learn enough Linux, and have an SD Card to spare, it can be a fun exercise in learning to build your own Linux + clib + GNU Tools + X11 + WM + Desktop Environment + all the programs you want. Once you have done it completely from the ground up, starting from source, you get a better appr...

Structured Procedural BASIC, why not?

Since I am back I have to bring it up. What form? What about something like MS-QuickBASIC for the Macintosh, with some of the extensions from MS-BASIC PDS, and an implementation of pointers on top? I would implement the pointers in the same manner as they are implemented in BBC BASIC V (AKA ARM BASI...

Re: low cost or free assembler books / tutorials?

There are many good resources for learning ARM Assembly.
