1  Using Arduino / Project Guidance / Re: Word lookup table on: August 12, 2014, 01:27:43 pm
Haha, funny thoughts.
16-bit is to run four stepper motor with various speed at various time.
To Robin2, now I realize it is possible to run this with 304 pins just if I have many small microcontrollers connected pins the main Arduino DUE with 4-bit lookup table. Is that possible ? All the DUE card need to get are; aircraft position such as angle, compass degree, magnetic degree, , NAV, ADF, RSBN stations, XY coordinate, and all necessity information. Let me check.

In one sentence, one program as a traffic lights that run many microcontrollers.

Run this:
I'm not prepared to run something on my PC without knowing what it is.

Now I count necessity of pins in LibreOffice Calc. 304 pins without altitude, speed, temperature, and vertical speed indicator in the navigation panel.

Where do you propose to find 304 pins? Let's stay with the original question, which at least seems to be possible.

You need to explain what you are trying to make and what the 16-bit look-up table is for. I repeat my earlier question

Can you explain (or give an example of) how the data in one of your 16 bit words would be used.

Why have you decided on 16 pins, and what is each of them for?

...R
It is a navigation system for Il-62 that I will simulate with X-Plane 10 simulator.
Use many microcontrollers connect together. For example, two pins for eight pins for two stepper motor.
Now I realize that 16-bit with 65536 values lookup table is too much for the arduino card, so I use 8-bit instead which takes much, much less storage in the arduino card.
I will use some microcontrollers to run this navigation system. But actually I need to design a dedicated computer for that to connect with a common home computer.

But still I have to build fuel dump panel, main panel, engine startup panel, electric panel, throttle, autopilot, and other things.

Run this:

So I thinking to use 16-bit for each four stepper motor. Or what do you thinking?
6  Using Arduino / Project Guidance / Re: Word lookup table on: August 11, 2014, 09:32:09 pm
I forget to add that the four motors will run at various speed that can run faster and slower mixed.  Sometimes one motor run slow, other fast, one does not run, one run very fast; other time depends on situation. How much is 16 MHz able to run ?
7  Using Arduino / Project Guidance / Re: Word lookup table on: August 11, 2014, 09:26:07 pm
I have Arduino MEGA2560. How to I make lookup without eating a lot of 256kb ?
8  Using Arduino / Project Guidance / Word lookup table on: August 11, 2014, 09:20:36 pm
I am considering to use word (16-bit) lookup table to run four stepper motor, and to save program size.
I am thinking to use 16-bit for 16 pins. Is that possible ?
What do you think about it ?
9  Using Arduino / General Electronics / Re: on/off switches in resistor voltage divider on: July 04, 2014, 08:51:53 am
I have two pieces of 10 kOhm , shall I have 18 or 22 kOhm pull-down ?
Now I trying just one rotary encoder to practice, and additional one more to practice with two analog inputs. It is just for practice test.

See this http://caffeinatedaviator.com/2012/04/arduino-project-for-x-plane-10/ Arduino project for X-Plane 10, as you see, you have right that I need to program in arduino 256KB to let X-Plane SDK detect pins, right ?
11  Using Arduino / Interfacing w/ Software on the Computer / Re: X-Plane SDK with Arduino Card on: June 28, 2014, 11:31:53 am
Thus 256 KB is not a lot to put in for 52 pins.

Hi.
If I have an ethernet shield version to interface with X-Plane 10 SDK, is that enough to use UDP to send message to each pin so I do not need to programming any function in Arduino card but just let X-Plane 10 SDK send message directly to each pin ?
13  Using Arduino / Networking, Protocols, and Devices / X-Plane 10 SDK plugin direct to Arduino pins ? on: June 27, 2014, 07:13:34 pm
Is that possible to programming plugin in X-Plane 10 direct to Arduino pins through ethernet without need to programming something to Arduino ?
14  Using Arduino / General Electronics / Re: on/off switches in resistor voltage divider on: June 26, 2014, 10:08:36 am
Don't forget adressing size, instruction, memory space, etc.

A 8-bit microcontroller is enough to run some stepper motor at each. For example 3-bit is for instruction and such, 2-bit for pins to the stepper motor, 2-bit for stop the instruction set, and one additional bit for example with toggle switch. That should be enough with one 8-bit microcontroller for 6-8 stepper motors. Thus, I need 10 microcontrollers, which should support ethernet to share with ONE ethernet port in the main computer, to make it easier than USB and other options.

Or another solution is to have a lot of microcontrollers with ethernet support through switch to share with one computer?
15  Using Arduino / General Electronics / Re: on/off switches in resistor voltage divider on: June 26, 2014, 09:46:56 am
I think that I2C bus that run less than 100 kHz is too slow for the task I am find a solution for.
