The Great DIY Arduino Controller Project

Now i have all the gear needed, now to start coding it all together

Hi, looks good. Let me know if I can help or you need a second view on things.

 

[SmartAlecLights]

help is what i need now,
still trying to setup a bitbucket for the source codes of the different arduino's.
So there's lots of coding in different area's needed,
as im only using basic code i find (so things will be patchy)
im still also trying to draw a basic wiring diagram for it all..

Ive Learned one thing tonight, Github is so much easyer
https://github.com/smartaleciam/GreatDIYDimmer
So start your hacking..lol

 

[SmartAlecLights]

just working out how the lcd display will look when displaying the sliders an joysticks

This is all above my pay-grade

any update on this project Alec

Latest Update from 2017,

Hardware side :-
Still slowly milling out the plastic for the panel, got a perfect box from a xmas presant (i asked for) to be the roadie case for it.
Got the wrong leds, after i went against the voice in my head telling me to test a example first.. (thats the whole button matrix board to do) (16 rgb leds + pixel boards),

Coding side :-
'Clock Time' working,
'RFID' access working,
SD card access working (more work needed),
'Sliders + pots' values screen completed,
but with all that i lost the touch screen function (no great rush to fix yet)

So im getting there slowly..

Hi, I notice that the Pixel and DMX outputs are still empty in the github files. I have no idea how github works so offer these here.

DMX output on Nano / Mega Tx pin:

      //Send DMX on usart0



      UCSR0B = (1 << TXEN0); // Enable transmitter

      UCSR0A |= (1 << U2X0); // Double transmission speed

      while ( ! (UCSR0A & (1 << UDRE0)) );  // Wait for buffer to empty



      // Send break and mark after break



      UBRR0H = 0; UBRR0L = 17; // Set baud to 100,000bps @ 16Mhz clock

      UCSR0C = (3 << UCSZ00) | (2 << UPM00); // Set 8 data bits, E parity and 1 stop bit.

      UDR0 = 0x00; // load data into usart buffer and send

      UCSR0A |= (1 << TXC0); // Clear transmit complete flag

      while ( ! (UCSR0A & (1 << TXC0)) ); // Wait for transmit complete flag



      // Send start code 0x00



      UBRR0H = 0; UBRR0L = 7; // Set baud to 250,000bps @ 16Mhz clock

      UCSR0C = (1 << USBS0) | (3 << UCSZ00); // Set 8 data bits, no parity and 2 stop bits

      UDR0 = 0x00; // Load data into usart buffer and send



      // Send data



      for (int n = 126; n < 638; n++) { // Loop 512 times

        while ( ! (UCSR0A & (1 << UDRE0)) ); // Wait for buffer to empty

        UDR0 = data[n]; // load data into usart buffer and send

}

Pixel output on Nano / Mega Tx pin but is inverted (a fix later in this post):

      UCSR0C = 0xC0; // Set MSPI data mode 1.

      UCSR0B = (1 << TXEN0); // Enable transmitter

      UCSR0A |= (1 << U2X0); // Double transmission speed

      UBRR0H = 0; UBRR0L = 1; // Set baud to 4,000,000bps @ 16Mhz clock



      // Send data

      cli();

      for (int n = 126; n < 638; n++) { // Loop 512 times



        op1 = B01111011; // set values to zero pixel

        if (data[n] & B10000000) op1 &= B10011111; // mask as 1 if pixel data bit is a 1

        if (data[n] & B01000000) op1 &= B11111100; // mask as 1 if pixel data bit is a 1

        while ( ! (UCSR0A & (1 << UDRE0)) ); // Wait for buffer to empty

        UDR0 = op1; // write to output buffer



        op2 = B11011110; // set values to zero pixel

        if (data[n] & B00100000) op2 &= B11100111; // mask as 1 if pixel data bit is a 1

        while ( ! (UCSR0A & (1 << UDRE0)) ); // Wait for buffer to empty

        UDR0 = op2; // write to output buffer



        op3 = B11110111; // set values to zero pixel

        if (data[n] & B00010000) op3 &= B00111111; // mask as 1 if pixel data bit is a 1

        if (data[n] & B00001000) op3 &= B11111001; // mask as 1 if pixel data bit is a 1

        while ( ! (UCSR0A & (1 << UDRE0)) ); // Wait for buffer to empty

        UDR0 = op3; // write to output buffer



        op4 = B10111101; // set values to zero pixel

        if (data[n] & B00000100) op4 &= B11001111; // mask as 1 if pixel data bit is a 1

        if (data[n] & B00000010) op4 &= B11111110; // mask as 1 if pixel data bit is a 1

        while ( ! (UCSR0A & (1 << UDRE0)) ); // Wait for buffer to empty

        UDR0 = op4; // write to output buffer



        op5 = B11101111; // set values to zero pixel

        if (data[n] & B00000010) op5 &= B01111111; // mask as 1 if pixel data bit is a 1

        if (data[n] & B00000001) op5 &= B11110011; // mask as 1 if pixel data bit is a 1

        while ( ! (UCSR0A & (1 << UDRE0)) ); // Wait for buffer to empty

        UDR0 = op5; // write to output buffer

      }

      sei();

You can buffer and invert the Pixel output with an RS485 module it also has the advantage of offering the differential signal for DMX. I don't have a schematic in my dropbox at the moment, I'll clear some space next week.

What about using a raspberry Pi? In built support for LCD screens and inputs, no analog inputs though.
Richard

How many Rx/Tx in/outs can a rasp pi have?
as the sliders an buttons are both serial Rx/Tx lines

it would be great to have the processing power of a rasp pi,
but sadly i have no knowledge on how to design such a interface.

but if anyone is able to chip in.. it would be great to have 2 output versions going (arduino/rasp pi) for people to choose from

Latest update,
The Soft-touch Pixel Button Matrix section is completed,
It can now change the colour of the pixels an read the button inputs,
While sending the info over the Serial line to the main LCD Mega Controller

After 6hrs, of soldering,
I can now say the sliders are all soldered up
Im still cutting the plastic with the dremel.. (slow process without a CNC)

 

[bjpc2716]

it look great

getting there Alec

 

[SmartAlecLights]

Its slowly getting there.. now is the hard part of getting the arduino's to all talk nicely to each other..
