II'm not sure about pin 24.

I'm going to remove R10, i'll tell you if it works or not.

[Rhab 1]

Thank you very very much. Now my Display works as it should work.

Lesson: read the data-sheets!

[Rhab 1]

you're right... and not only the ti-datasheet, but also the manufacturer-datasheet too...

hi,

now i got a new problem.

what i want to do is switching between different "screens", which all show different measurement-data (as changing string). If i use only one "screen", there is no problem. But in the moment i draw a button (which should be used to switch "screen") the changing values can't be displayed correct (the value is only white pixel-bulk)

 

here you can see the value 2x (second character is changing in this moment) without button

 

here you can't see any value with button...

here is my code(the functionality of the button is not implemented yet, but this shouldn't be a problem...):

#include "Energia.h"
#include "SPI.h"
#include <LCD_graphics.h>
#include "LCD_GUI.h"

#define K35_SPI;
#include "Screen_K35_SPI.h"
Screen_K35_SPI myScreen;

// Define variables and constants
uint16_t value=0;
boolean increase=true;

uint16_t option=1;
// option 1 => Screen 1 
// option 2 => Screen 2
// option 3 => ...


//Define Buttons
button bRight;
//button bLeft;

void setup()
{
  Serial.begin(9600);
  Serial.println("begin... ");
  myScreen.begin();
  myScreen.setOrientation(1);
  myScreen.clear();
  //myScreen.dRectangle(myScreen.screenSizeX()-30, 0, 30, myScreen.screenSizeY(), myColours.red);
  bRight.dStringDefine(&myScreen, myScreen.screenSizeX()-30, 0, 20, 40, ">",   myColours.white, myColours.red);
  bRight.enable(true);
  bRight.draw(false);
}

void loop()
{
  switch(option){
  case 1:
    if(value==100){
      increase=false;
    }
    if(value==0){
      increase=true;
    }
    myScreen.setFontSize(myScreen.fontMax());
    myScreen.gText((myScreen.screenSizeX()-10*myScreen.fontSizeX())/2,
      (myScreen.screenSizeY()-myScreen.fontSizeY())/2, "   ", myColours.black);
    if(value<10){
      myScreen.gText((myScreen.screenSizeX()-10*myScreen.fontSizeX())/2,
      (myScreen.screenSizeY()-myScreen.fontSizeY())/2, "  " +
        String(value, DEC) , myColours.white);
    }               
    else if(value<99){
      myScreen.gText((myScreen.screenSizeX()-10*myScreen.fontSizeX())/2,
      (myScreen.screenSizeY()-myScreen.fontSizeY())/2, " " +
        String(value, DEC) , myColours.white);
    }
    else{
      myScreen.gText((myScreen.screenSizeX()-10*myScreen.fontSizeX())/2,
      (myScreen.screenSizeY()-myScreen.fontSizeY())/2,
      String(value, DEC) , myColours.white);
    }
    myScreen.gText((myScreen.screenSizeX()-2*myScreen.fontSizeX())/2,
    (myScreen.screenSizeY()-myScreen.fontSizeY())/2,
    "km/h" , myColours.white);
    if(increase){
      value++;
    }
    else{
      value--;
    }
    break;
  case 2:
    myScreen.gText((myScreen.screenSizeX()-10*myScreen.fontSizeX())/2,
    (myScreen.screenSizeY()-myScreen.fontSizeY())/2, 
    "Screen 2!" , myColours.white);
    break;
  }
}

solved my Problem... i forgot

 myScreen.setFontSolid(true);

now it works

There's no secret, Read the manual!

Hi!

 

I'm testing a EducationalBP MKII (board revision 1.1) which I adquired with the MSP432 launchpad. When running the MSP432 binary examples build in Code Composer, the display and all other things works. When I go to Energia and run a example, the compiler returns error 2 in the EduBPMKII_Screen libraries, saying the board isn't compatible...

 

When I tried to test the Energia examples using my Tiva C launchpad, all worked, except that use the screen. All examples compiles, the RGB led, joystick and buzzer works, but the screen stay blank... Running the LCD_protocol100 example, it returns in serial monitor data about the display, but it still blank.

 

I tested the examples in Energia 12, 14 and 16.

 

That can be a problem in the libraries or in my boosterpack? There are some other tests can I do to solve the problem?

 

Thanks in advance!

[Rei Vilo 695]

The library was developed some time ago, when the MSP432 wasn't available.

 

The sketches check the MCU, and the __MSP432P401R__ isn't listed.

#if defined(__MSP430F5529__)
#define ROWS 32 // max 80
#define COLS 32 // max 60
#elif defined(__LM4F120H5QR__)
#define ROWS 64 // max 80
#define COLS 64 // max 60
#else
#error Board not supported
#endif

For the LM4F120 / TM4C123, same answers as said previously. R9 and R10 shunts pin 23 to 14 and 24 to 15.

Thanks @@Rei Vilo ! I removed both resistors and the LCD worked!

[Rei Vilo 695]

You can use this excellent (Universal) Color LCD graphics library (2).

my kentec display is gathering dust  . No alternatives for  Kentec Screen_K35?

[Rei Vilo 695]

The library for the Kentec 3.5" SPI has been added to Energia, with the game of life as example.

 

See Energia/hardware/lm4f/Kentec_35_SPI.

Hi All,

I am currently trying to get a Kentec K35 Display working on the MSP432 Launchpad. Is there an example Library available to get the basics running, and does R9 need to be removed? It was shipped to me with R10 removed and R9 in place. Any thoughts or help would be greatly appreciated.

Thanks

Tom

[Rei Vilo 695]

There is no R9 on the MSP432 LaunchPad. The link posted before should work with minor adaptations.
