    I see couple of problems, I will comment once I get my coffee.
     
     
    OK, remove
    // setup USIB P1SEL |= LCD5110_SCLK_PIN + LCD5110_DN_PIN; P2SEL |= LCD5110_SCLK_PIN + LCD5110_DN_PIN;  
    Then change while in writeToLCD to
    while(!(USICTL1 & USIIFG)) ; You may also want to remove USIIE from config
    USICTL1 |= USICKPH + USICKPL;  
    I don't have access to 2231 right now, so this is all untested.

    You need to do 3 things to use USI
     
    1. remove USCI configuration and add USI config (here's an example)
    USICTL0 |= USIPE6 + USIPE5 + USIMST + USIOE; USICTL1 |= USICKPH + USICKPL + USIIE; USICKCTL = USIDIV_7 + USISSEL_2; USICTL0 &= ~USISWRST;  
    2. swap data pin from P1.7 to P1.6
    3. instead of writing to TX buffer, write to 2 registers below
    USISRL = data; USICNT |= 8;

    I wrote some code for the nokia lcd using spi a couple of months ago and after seeing Robs post I thought I'd post mine as well.

    sorry about the video quality I lost my good camera in a drift boat accident

    bitmap 2 LCD http://bitmap2lcd.com
    lcd assistant http://en.radzio.dxp.pl/bitmap_converter/

    The program stores the # of button press's in flash so when power is restored the count doesn't start over.
    Maybe this will help somebody. :thumbup:
    cheers
  4. Like
    tanh reacted to RobG in Nokia 5110 display   
    Here's the code I am using to control 5110. It uses USCIB (2553) but USI (2231) can also be use without any problem or major updates.
    There is still a lot of work to be done, but basic text and some graphics can be displayed with the current version.
