Example

Here is an example of a setup using both preset functions:

What I want to achieve:

  • The function multiFunction2Bit24() will use a 2-bit encoder and a 12-position switch (resistor ladder switch) together to make a 24-position complex. Basically the position of the 12-position switch determines the button numbers for the encoder, making it very valuable for setting up in-car adjustments and other things.

  • I want:

    • MultiFunction setup in presets 1-4

    • 12-position switch and incremental encoder separated in presets 5-8

    • Both switches work as incremental encoders in presets 9-11

    • Preset 12 is for rally, so I want my thumb encoders inactive in this preset. I tend to hit them when the wheel goes wild and I dont want any stray button presses. I want the 12 position switch back to a MultiFunction function, but now with two buttons instead of the encoder.

The first thought when setting this up would be on the button numbering. Lets say I reserve button numbers 1-24 for the MultiFunction. If the MultiFunction is not used, the 12 position switch only needs the first 12 button numbers, 1-12, and the remaining 13-24 are free. So the 12-position switch can use buttons 13+14 in incremental mode, and the encoder can use button numbers 15+16. The two buttons used in MultiFunction in preset 12 needs to be able to use in presets 1-4 as well, when the encoder is used in MultiFunction - so these buttons need numbers higher than 24.

Lets say for this example that:

  • 12-position switch is analog switch #1, wired to arduino pin A3

  • Encoder is wired to Row 1, Columns 4+5

  • The two buttons are on Row 3 Column 3 and Row 4 Column 2.

The 10_MatrixAndAnalog.ino might look a bit like this

//------------------------------
//-------MATRIX VARIABLES-------
//------------------------------

uint8_t row[] = {2, 3, 4, 6};
const uint8_t rowCount = sizeof(row) / sizeof(row[0]);

uint8_t col[] = {10, 15, 14, 16, 5};
const uint8_t colCount = sizeof(col) / sizeof(col[0]);

bool nonMatrixIncluded = false;

uint8_t nonMatrix[] = {0};
const uint8_t nonMatrixCount = sizeof(nonMatrix) / sizeof(nonMatrix[0]);

//---------------------------------------
//--------MATRIX DESCRIPTION-------------
//---------------------------------------

const uint8_t buttonNumber[rowCount][colCount] =
{
  {26, 27, 28, 14, 0},     //ROW 1
  {40, 35, 36, 37, 38},    //ROW 2
  {39, 29, 24, 30, 31},    //ROW 3
  {41, 25, 34, 32, 33}     //ROW 4
};

//---------------------------------------
//--------ANALOG DESCRIPTION-------------
//---------------------------------------

const uint8_t analogButtonNumber[10] =         //ANALOG BUTTONS 1
{ 0, 42, 0, 0, 0, 0, 0, 0, 0, 0 };

const uint8_t analogButtonNumberIncMode[10] =  //ANALOG BUTTONS 2
{ 12, 54, 0, 0, 0, 0, 0, 0, 0, 0 };

Now, for the setup in 30_Switches.ino, none of these 4 switches that will swap functions should be mentioned there. They should all be sorted out in 31_RunningPresets.ino, and each preset should handle these switches somehow. If the switches are also given a function in 30_Switches.ino, that will override anything written in 31_RunningPresets.ino.

31_RunningPresets.ino setup:

Note that to inactivate the encoder in preset 12, I just had to not call the encoder function.

Now that the correct switch functions are used in each presets, we'll have to use 32_Presets.ino to set the correct switch modes in each preset. When presets(int8_t presetNumber) is run, all switch modes are set to 0. So only the switches that needs to be in a mode other than 0 needs to be included. In this case that means only the 12-position switch in presets 9-11, where it will be in mode 1.
