MSP430FR4133: 8-MUX LCD Example

Sorry, we don't have such an example for 8 MUX LCD.

I think you can generate one by referring to our 4 MUX code example by changing LCDCSSELx

Hello, I am using the 48-pin DGG package, where there I have selected the pin from L0 to L3, L8 to L19 and L24 to L27 as LCD segment function and L28 to L35 as LCD common function. I am trying to turn on the LCD segments using the following positions corresponding to the segments: LCDM0 to LCDM3, LCDM8 to LCDM19, LCDM24 to LCDM27. Is this memory access mode correct? Thank you.

Yes. You are right, you can also refer to this picture.

Thanks for your comments. More some details:

For the LCD configuration, I am doing the following (observe that the segments are not continous, there is 2 gaps, one from L4 to L7 and L20 to L23):

LCDPCTL0 = 0xFF0F; 
LCDPCTL1 = 0xFF0F; 
LCDPCTL2 = 0x000F;

LCDCSSEL0 = 0x0000; 
LCDCSSEL1 = 0xF000; 
LCDCSSEL2 = 0x000F;

LCDM28 = 0x80; // L28 =  COM_7
LCDM29 = 0x40; // L29 =  COM_6
LCDM30 = 0x20; // L30 =  COM_5
LCDM31 = 0x10; // L31 =  COM_4
LCDM32 = 0x08; // L32 =  COM_3 
LCDM33 = 0x04; // L33 =  COM_2
LCDM34 = 0x02; // L34 =  COM_1
LCDM35 = 0x01; // L35 =  COM_0

and I am trying to turn on/off the LCD segments using the following positions corresponding to the segments: LCDM0 to LCDM3, LCDM8 to LCDM19, LCDM24 to LCDM27.

Is it correct? 

Or should it be this way, considering no gaps??

LCDPCTL0 = 0xFFFF; 
LCDPCTL1 = 0x0FFF; 
LCDPCTL2 = 0x0000;

Thanks for your comments.

LCDPCTL0 it is used to enable the pin. I advise you just enable the pin used by you.

I think you can try to by yourself to check if it is work.

My doubt is that I want to use 20 LCD segments starting from pin (L0 to L3, L8 to L19, L24 to L27) and pins L28(Com0) to L35(Com8) as common pins. As I told you, if you look at the datasheet of this MSP430FR4133 48-pin model, there are pin gaps L4 to L7 and L20 to L23. Considering this, how should I configure LCDPCTL0, LCDPCTL1, LCDPCTL02, LCDCSSEL0, LCDCSSEL1, LCDCSSEL2, LCDM28 to LCDM5 registers?

Considering these LCD segments, how can I write on each LCD segment memory? Should I considering the following positions corresponding to the segments: LCDM0 to LCDM3, LCDM8 to LCDM19, LCDM24 to LCDM27 ?

I am asking because I tried to put to workk and there is no success. I am looking forward to hearing from you.

Thanks a lot.

Sorry, I don't have a 8mux LCD in hand. 

Here is the document for you to refer https://www.ti.com/lit/an/slaa654a/slaa654a.pdf

My advice is that can you test the wave of these pins to check if they are all work.
