CCS/MSP430FR4133: LCD with MSP430FR4133

Hello,

If you don't have the structure of the LCD, I'm afraid that I can't help you.

Any ideas please,or software already wrote to LCD with these pins??!!!?

any sample for any LCD sample with this MSP430FR4133 controller.

If you're using the Launchpad, the LCD part number is probably in the BOM, in the Design Files (.zip) available on the product page. Launchpad User Guide (SLAU595A) Table 3 calls it a "FH-1138P".

http://www.ti.com/tool/MSP-EXP430FR4133

That zip file also apparently contains examples specific to the Launchpad, at least some of which presumably use the LCD. The  I think there are some wiring conventions for segment LCDs, so you might be able to use pieces of the Examples without a Launchpad.

There are also code examples, including for the LCDE, at:

hi,

i tried the example lcd_01.c and it did not work, the lcd start blanks and didn't show any thing, please help

Can you post a picture of your board?

FYI

Is there any marking on the board to indicate a part number. If you look at the IC really close, you might be able to use the part number to get a data sheet.

Example LCDE_01 expects to see a 32kHz crystal, and I don't see one of those on your board. The crystal is not actually required (on the FR4133). The first experiment might be to remove these lines:

#if 0
    // Configure XT1 oscillator
    P4SEL0 |= BIT1 | BIT2;                                     // P4.2~P4.1: crystal pins
    do
    {
        CSCTL7 &= ~(XT1OFFG | DCOFFG);                         // Clear XT1 and DCO fault flag
        SFRIFG1 &= ~OFIFG;
    }while (SFRIFG1 & OFIFG);                                  // Test oscillator fault flag
    CSCTL6 = (CSCTL6 & ~(XT1DRIVE_3)) | XT1DRIVE_2;            // Higher drive strengthr
#endif // 0

I looked at the whole board but I didn't find anything all I know that the board connected parallel to LCD pins, any tips to know LCD pins from LCD itself. I can try.

I will try try and feed you back.

Thank you

The LCD interface chip is probably a Hitachi HD44780. You can google the datasheet for that and see if the connections make sense.

it also did not work, when come to this line:
    LCDCTL0 |= LCD4MUX | LCDON; 

LCD  start blinking very fast and make sound. any another tips?

unfortunately  it is not Hitachi HD44780 i i think this lcd can write on it in arabic words.

Sorry, I missed this: 

> LCDCTL0 = LCDSSEL_0 | LCDDIV_7; // flcd ref freq is xtclk

LCDSSEL=0 is XT1CLK (the code you just removed since it didn't work). This should make it use ACLK (REFOCLK, an internal oscillator) instead:

> LCDCTL0 = LCDSSEL_1 | LCDDIV_7; // flcd ref freq is ACLK (REFOCLK)

-----------------

I'm hoping that gets rid of the squeal. If you still don't see anything, the next experiment I was going to suggest was writing 0xFFFF into all the segment memory. I did this on my Launchpad from the debugger (Registers->LCD_E->LCDM0W, LCDM2W, and so on). We don't know what the segment map is, but if we light up enough of them I'm hoping you'll see something.

-----------------

Arabic segments sounds pretty exotic. I hope you'll post a photo when you get there.
