I did the test again and now gave compile error.

I corrected this error by adding lines"_" the error that occurred, he stopped giving the error but still did not work.

He comes to flashing the LCD changing the background color the same color put back later.

still did not work here. Someone help me?

i try connect 

 

 

CS - P1.0

SCK - P1.5

DIO - P1.7

 

i solve the _delay_cycles problem but not working i see only dark blue screen.

 

damn

 

need help.

[pcesar12 0]

worked, now only thing I'm finding strange is that the screen light starts strong and  go weakening, will not give up almost to see

 

some information about light?

 

color problem

 

mbed version:

 

 

msp430 version:

 

 

why bad color in msp 430?

Hey i try put

 

setColor16(COLOR_16_GREEN);

    drawString(5, 5, "TESTE TESTE TESTE");

 

and i see RED COLOR IN LCD o.O OMG what is happening? 

 

Will the color mapping for the PCF8833 is wrong?

[RobG 1,892]

Use 8 bit color with PCF8833 (setColor(color).) I don't think I ever used other color depths on PCF8833 based displays, so you will have to figure out how to map them.

[pcesar12 0]

I managed to fix, I made a new configuration for the PCF8833 now he is running in 16-bit is much better colors, then step guidelines on how to do this.

[pcesar12 0]

To write the text I do drawString (x, y, "text")

but how do I write here instead of a text that I have a variable in the program after a calculation processing.

[pcesar12 0]

For Everyone:

 

To improve the performance of Sparkfun LCD BreakBoard color with Nokia 6100 (11062) with the controller PCF8833, you must change the operating mode to 16bits.

Below is some information with pictures of how to make this change and how to set PCF8833.

 

colorLCD.h

 

colorLCD.c:

 

Now you had a much better performance of colors, colors more vibrant and visible on the screen.

 

Have fun.

After searching:

 

Use:

 

 

 

#include <stdio.h> //require for sprintf

char buffer[];
value=50;

sprintf(buffer,"R:%ld",value);

drawString(x, y, buffer);

Then connect the pins as follows: CS - P1.0 SCK - P1.5 DIO - P1.7 RESET - not using reset, tie it to any available pin on your LaunchPad and add a piece of code to reset your LCD before configuring. Alternatively, you can just tie it to Vcc. You must also connect Vcc and GND.

// pins

#define LCD_SCLK_PIN BIT5             // SCK

#define LCD_SCLK_PORT P1OUT

#define LCD_SD_PIN BIT7                 // DIO

#define LCD_SD_PORT P1OUT

#define LCD_SD_PORT_IN P1IN

#define LCD_SD_DIR P1DIR

#define LCD_SCE_PIN BIT0               // CS

#define LCD_SCE_PORT P1OUT

#define LCD_DC_PIN BIT4                 //  ?  -   What is this? And do this for PCF8833?

#define LCD_DC_PORT P1OUT

[RobG 1,892]

DC is data/controll. PCF8833 uses 9 bit SPI so DC is not used (bit #9 is used for this.)

[Bujhm666 0]

Thanks. But it is used in the code, regardless of the type of controller:

 

 

// code duplication, but we are saving clock cycles by not passing dataCommand
void writeData(u_char data) {
    u_char c = 0;
    LCD_SELECT;
#ifdef SPI9BIT
    LCD_SD_OUT_HI;
    LCD_CLOCK;
#else
    LCD_DC_HI;
#endif
    while (c < 8) {
        (data & 0x80) ? (LCD_SD_OUT_HI) : (LCD_SD_OUT_LO);
        LCD_CLOCK;
        data <<= 1;
        c++;
    }
    LCD_DESELECT;
}
 
// code duplication, but we are saving clock cycles by not passing dataCommand
void writeCommand(u_char data) {
    u_char c = 0;
    LCD_SELECT;
#ifdef SPI9BIT
    LCD_SD_OUT_LO;
    LCD_CLOCK;
#else
    LCD_DC_LO;
#endif
    while (c < 8) {
        (data & 0x80) ? (LCD_SD_OUT_HI) : (LCD_SD_OUT_LO);
        LCD_CLOCK;
        data <<= 1;
        c++;
    }
    LCD_DESELECT;
}
 

[RobG 1,892]

When using PCF8833, you define SPI9BIT which is used in the conditional below.

#ifdef SPI9BIT
    LCD_SD_OUT_HI;
    LCD_CLOCK;
#else
    LCD_DC_HI;
#endif

9 bit SPI will set data pin and generate clock, 8 bit SPI will set DC pin.

Understood. Thank you again.

Rob- Can I copy your font_5x7.h?  Want to use it for my Okaya (ST7579) lib for my Renesas RX projects.  I'll keep your authorship info in the file.
