SOLVED

[Rei Vilo 695]

Hi,

 

I tried to port the (Universal) Color LCD graphics library for the Color LCD BoosterPack to Energia but didn't manage to get it work.

 

Any help?

I'm not familiar with Energia.. but more info would be nice.. compiler errors.. memory etc?

The first thing you should do is remove all Nokia related code, it will make things easier.

Hi!

 

Thanks for the tips. I've cleaned the original code, added a setup() and loop() functions.

 

Please find it attached:

colourLCD_main.zip

 

There's no error during compilation and upload.

 

When running, the screen remains white.

 

I logged the SPI channels:

colorLCD.logicdata.zip

[RobG 1,892]

Channel #1 looks like MOSI, not MISO

Channel #3 is D/C, not enable, right?

Were you able to get your LCD to work with my original library?

Also, removed more unnecessary stuff, see attached files.

colorLCD.cpp

colorLCD.h

[Rei Vilo 695]

Yes, you're right! Thanks!

 

I've included the updated .h and .cpp files and here are the new traces:

Do you have jumpers on the 2x2 header (horizontal)?

Can you do capture during readIDs()? You should see LCD response on MISO.

Try increasing delay before communicating with LCD to ~1s.

__delay_cycles(16000000); // wait before reading IDs

Thank you for your help.

No, I removed the jumpers for P1.0 and P1.6.

The MISO line is empty.

Could you please post the compiled .hex file so I can upload it with mspdebug and check my screen is fine?

mspdebug rf2500 --force-reset prog colourLCD_main.hex

 

I opened the issue :arrow: Color LCD Booster Pack Library on Energia at the Energia GitHub repository.

[RobG 1,892]

Thank you for your help.

No, I removed the jumpers for P1.0 and P1.6.

I was referring to J3 on the LCD board, see the picture on github

I am not using mspdebug or Energia, but I can test your code and report.

[RobG 1,892]

Code works as expected.

However, read functions do not work with JD-T, they were used for Nokia displays. I will fix them later on.

I didn't place the jumpers J3 correctly :oops: .

 

They are now horizontal and the screen works fine as expected!

 

The USI / USCI is rather confusing. I've faced the same mistake with the RX / TX jumpers.

 

Thank you so much for your help! :thumbup:

[RobG 1,892]

Nice! It's always the small things

 

USCI - output is on P1.7, input on P1.6

USI - output on P1.6, input on P1.7

 

On my next board, I will have USCI shorted by default.

 

Here's working readChar function that can be used to read RDID1, RDID2, and RDID3 for example.

char readChar(char command) {
 char a = 0;
 char c = 0;
 LCD_SELECT;
 P1OUT &= ~LCD_DC_PIN;
 while (c < 8) {
   (command & BIT7) ? (P1OUT |= LCD_SD_PIN) : (P1OUT &= ~LCD_SD_PIN);
   LCD_CLOCK;
   command <<= 1;
   c++;
 }
 P1DIR &= ~LCD_SD_PIN;

 while (c < 16) {
   a <<= 1;
   P1OUT |= LCD_SCLK_PIN;
   if (P1IN & LCD_SD_PIN)
     a |= BIT0;
   P1OUT &= ~LCD_SCLK_PIN;
   c++;
 }

 LCD_DESELECT;
 P1DIR |= LCD_SD_PIN;
 return a;
}

Please find the working library for Energia attached.

colourLCD_main.zip

 

 

One caveat however: nothing is displayed when Serial is used.

Just uncomment the lines to do the test.

// Serial.begin(9600);
// Serial.println("colorLCD");

I'm reporting it to :arrow: Color LCD Booster Pack Library on Energia on GitHub.

[Rickta59 589]

I think you are encountering a pin conflict. Serial uses P1.1 and P1.2. It looks like the color lcd code uses P1.2.

 

#define LCD_SCE_PIN BIT2

#define LCD_SELECT P1OUT &= ~LCD_SCE_PIN
#define LCD_DESELECT P1OUT |= LCD_SCE_PIN

 

You might try changing LCD_SCE_PIN to a different unused pin.

I am making changes to the newest version of my CLCD booster pack, so if you have suggestions or requests, now is the time
