  1. It seems very weird. This project (5110 LCD) and the LCD 16x2 project, and also a 7-segment LED project I run successfully on Arduino. However using Tiva C with Energia it didn't work although I used the pin numbers instead of port names. Is there anything to do with the clock frequency that affects the timing (tiva C is much faster than Arduino?)
  2. I've change as what you suggested, but... no hope. #if defined(__MSP430G2553__) LCD_5110_SPI myScreen; #elif defined(__LM4F120H5QR__) LCD_5110_SPI myScreen(10, // Chip Select 11, // Data/Command 2, // Reset 9, // Backlight PUSH2); // Push Button 2 #endif boolean backlight = false; uint8_t k = 0; How about the Serial clock and Serial data? I connected them to PB_4 and PB_7 respectively.
  3. Thanks Velo, but I'm afraid I don't fully understand. Do you mean to change the following lines? (e.g. change PA_7, PA_2... into pin numbers) #if defined(__MSP430G2553__) LCD_5110_SPI myScreen; #elif defined(__LM4F120H5QR__) LCD_5110_SPI myScreen(PA_7, // Chip Select PA_2, // Data/Command PB_5, // Reset PA_6, // Backlight PUSH2); // Push Button 2 #endif As what I done I can still toggle the backlight after uploading the code. It means using port names didn't affect, isn't it?
  4. Hi all, I have some troubles with Nokia 5110 LCD to run on Tiva C using Energia. Here is my full code. I wire as below: PA_7, // Chip Select PA_2, // Data/Command PB_5, // Reset PA_6, // Backlight PB_4 = SCK (2) = Serial Clock PB_7 = MOSI (2) = Serial Data I'd done compiled and uploaded the code onto the chip but there was nothing displayed on the 5110 Screen. I still can toggle the backlight on/off by the push button, it means that the loop is running. I think there may be some issues with the SPI driver. Thank you a lot, For your easy reference, I post the main .ino code here for preliminary skimming: #include "Energia.h" // Core library for code-sense #if defined(WIRING) // Wiring specific #include "Wiring.h" #elif defined(MAPLE_IDE) // Maple specific #include "WProgram.h" #elif defined(MPIDE) // chipKIT specific #include "WProgram.h" #elif defined(ENERGIA) // LaunchPad, FraunchPad and StellarPad specific #include "Energia.h" #elif defined(CORE_TEENSY) // Teensy specific #include "WProgram.h" #elif defined(ARDUINO) && (ARDUINO >= 100) // Arduino 1.0 and 1.5 specific #include "Arduino.h" #elif defined(ARDUINO) && (ARDUINO < 100) // Arduino 23 specific #include "WProgram.h" #else // error #error Platform not defined #endif // Include application, user and local libraries #include "SPI.h" #include "LCD_5110_SPI.h" // Variables /// P._. / PB_4 = SCK (2) = Serial Clock /// P._. / PB_7 = MOSI (2) = Serial Data #if defined(__MSP430G2553__) LCD_5110_SPI myScreen; #elif defined(__LM4F120H5QR__) LCD_5110_SPI myScreen(PA_7, // Chip Select PA_2, // Data/Command PB_5, // Reset PA_6, // Backlight PUSH2); // Push Button 2 #endif boolean backlight = false; uint8_t k = 0; // Add setup code void setup() { #if defined(__MSP430G2553__) SPI.begin(); SPI.setClockDivider(SPI_CLOCK_DIV2); SPI.setBitOrder(MSBFIRST); SPI.setDataMode(SPI_MODE0); #elif defined(__LM4F120H5QR__) SPI.begin(); SPI.setClockDivider(SPI_CLOCK_DIV128); // for LM4F120H5QR DIV2 = 4 MHz ! #endif myScreen.begin(); myScreen.setBacklight(backlight); myScreen.text(0, 0, "Hello!"); delay(1000); myScreen.clear(); myScreen.text(0, 5, "Light off"); } // Add loop code void loop() { if (myScreen.getButton()) { backlight = (backlight==0); myScreen.setFont(0); myScreen.text(0, 5, backlight ?

"*" : " "); k ++; k %= 14; delay(200); } Nokia5110.rar
