GUISlice example ex40_ard_ctrls_small_seesaw.ino with ard-shld-adafruit_18_joy.h config works but not my own from GUIslice Builder does not

[Dowster64]

In the working example the focus/highlight can be seen, and it can be shifted by the use of the buttons (or the joystick as originally written). In my version I cannot see the focus shifting and I cannot select a button. I created a simple display with two GUI buttons (OK and QUIT) to test using buttons A, B and C.

From the generated code from the builder I manually added a copy of the mapping from the working example (ex40) for my buttons (in setup()) and also the max input in the header file as this is not generated by the builder:

#define MAX_INPUT_MAP       6
gslc_tsInputMap             m_asInputMap[MAX_INPUT_MAP];

I am using an Arduino Uno R4 Minima platform and Sloeber IDE. I can successfully run ex40_ard_ctrls_small_seesaw.ino.

I would really appreciate some help. I know there are some focus related functions but the example does not use them but works. So I am a little lost,
Thanks,

If any one else has the same issue the error was simple. The button mapping has to occur after function gslc_init() has been called. Here is the button mapping I used. If you put it in the arduino .ino file setup() function those lines go here (after the function defined in the auto generated header from builder) :

// ------------------------------------------------
  // Create graphic elements
  // ------------------------------------------------
  InitGUIslice_gen();

  gslc_InitInputMap(&m_gui, m_asInputMap, MAX_INPUT_MAP); 
  gslc_InputMapAdd(&m_gui, GSLC_INPUT_PIN_ASSERT,   GSLC_PIN_BTN_A,  GSLC_ACTION_FOCUS_PREV, 0);
  gslc_InputMapAdd(&m_gui, GSLC_INPUT_PIN_ASSERT,   GSLC_PIN_BTN_B,   GSLC_ACTION_PRESELECT, 0);
  gslc_InputMapAdd(&m_gui, GSLC_INPUT_PIN_DEASSERT, GSLC_PIN_BTN_B,   GSLC_ACTION_SELECT, 0);
  gslc_InputMapAdd(&m_gui, GSLC_INPUT_PIN_ASSERT,   GSLC_PIN_BTN_C, GSLC_ACTION_FOCUS_NEXT, 0);
  gslc_InputMapAdd(&m_gui, GSLC_INPUT_PIN_ASSERT,   GSLC_PIN_BTN_UP,    GSLC_ACTION_SET_REL, -10);
  gslc_InputMapAdd(&m_gui, GSLC_INPUT_PIN_ASSERT,   GSLC_PIN_BTN_DOWN,  GSLC_ACTION_SET_REL, +10);
 // etc etc

I have also tried adding those lines to the InitGUIslice_gen() function in the generated file after the gslc_init function call (it also works)

// ------------------------------------------------
// Create page elements
// ------------------------------------------------
void InitGUIslice_gen()
{
  gslc_tsElemRef* pElemRef = NULL;

  if (!gslc_Init(&m_gui,&m_drv,m_asPage,MAX_PAGE,m_asFont,MAX_FONT)) { return; }

  // Create the GUI input mapping (pin event to GUI action)
    // - The following is based on buttons that exist in the Adafruit Seesaw joystick shield
//    gslc_InitInputMap(&m_gui, m_asInputMap, MAX_INPUT_MAP);
// etc etc

@Dowster64 If you are doing a lot of work with this mcu combination you can make your life easier by editing the Builder's templates so thet it can inject your code automatically for any new projects.
Of course, if you are only doing one project with this mcu its no big deal.
The templates involved are all inside GUIsliceBuilder/templates
hdr.t and ino2.t

Just an FYI

Thanks @Pconti31, that was a really useful insight. It should help people with the Adafruit 1.8" Shield,
Thanks again.
