  1. Hello everyone, My friends and I are very interested to use Energia in one of our university project. We are using the following hardware: MSP432P401R Educational BoosterPack MKII We tried first to use the Built-in examples that come with Energia, and all the examples worked perfectly except the examples that interact with the LCD ( Ex: LCD_Joystick and LCD_LifeGame). Therefore, please, could anyone tell me how I can fix this? I really appreciate your help and time. Thanks. The error message that we got. Energia: 1.6.10E18 (Mac OS X), Bo
  2. Hi, I'm trying send GPS (adafruit Ultimate GPS FeatherWing) coordinates to another location using XBees and then displaying GPS data on an LCD (Sharp 96 Booster Pack) using Energia. This involves 2 pairs of Xbees (4 total 2 different ranges), 3 MSP-EXP432P401R (Black Version), the GPS and the LCD. I wrote some code for the first MSP432 on getting GPS data and getting it to the XBee to transmit to another MSP432 (connected to 2 XBees). Although I haven't been able to test it (GPS and XBees aren't here yet) I feel like it will at least be close if not functional.GPStoXBEE.ino After
  3. Hello fellows, I made a code to interact the MSP430, with the LCD, but now I would like to have it interact with the MSP432. And I'm having some problems because I want to use specific pins, can anyone help me change the code? My difficulty is: the MSP430 I use PORT P1 and P2, the problem is in the MSP432 I need PORT P2, P5 and P6 This is my connections LCD->MSP432: EN -> (P2 + BIT3) RS -> (P6 + BIT7) D4 -> (P2 + BIT6) D5 -> (P2 + BIT4) D6 -> (P5 + BIT6) D7 ->(P6 + BIT6) lcd.c lcd.h main.c main.h
  4. Is there a way to use the SoftwareSerial library on the Stellaris Launchpad TM4C123GXL board? I am trying to connect a Sparkfun serial enabled LCD screen to the board but the SoftwareSerial library is only compatible with 20, 16, and 8 MHz processors, and the TM4C123GXL is an 80 MHz chip. How can I use this LCD screen with the Stellaris Launchpad over a UART connection? Do I need to use SoftwareSerial or can I do without it? I am programming in Energia 0101E0017 on Windows 7 64 bit. Any help is greatly appreciated, thanks!
  5. For my next project I have to use a Nokia 5110 LCD with a MSP430G2553. After searching for a while on the internet I came across RobG's SPI-based driver. It's a great driver, but the problem is that I'll be using a I2C chip in this project too, so I decided to create a bit-bang driver. The code is extremely well documented and you should easily be able to use it for anything you want. Here's the GitHub repo: msp430-nokia-5110.
  6. Hey all, I recently got a Nokia 5110 LCD working using the LCD_5110 lib from GitHub. Works great, so thanks to giants whose shoulders I stand atop! I moved my chip (G2553) directly to the board as I have done several times before (with a pullup resistor on RST), and I loaded a little demo program on it with my "loader" board (just TEST, RST, GND, and VCC hooked up to the emulation side of an LP). Program loads and runs fine, but when I remove the loader and cycled power (I was just changing battery sources from a 6V pack to a 9V battery -- they are dropped to 3.3V), the LCD does not i

  8. I have a Spikenzie Labs LCD screen with an interface (screen utilizes the HD44780 chipset). I have it connected to an MSP-EXP432P401R (Rev 1.0). I have finally got code working that allows me to write to the LCD screen through the serial monitor, however I can only write to the screen for a short but varying amount of time. Sometimes I can print to the screen for 5 seconds, sometimes only for 1 second before communication cuts out. Here is the code I am using: #include <Wire.h> #include <LiquidCrystal.h> #define addr 0x40 >> 1 void setup() { Wire.begin(); Serial.beg
  9. Hello, I'm trying to get a standard 1602 LCD (16x2 from Raystar) connected to MSP432 with the I2C interface. Are there any existing libraries which could help me out? I've found some I2C libraries for Arduino but naturally they're not compatible, and the only existing Energia examples deal with CogLCD which uses a SPI interface (emerging question: is there a way to make SPI and I2C compatible?) or standard 16 pin connection. MSP432 is still a relatively fresh chip, so I can't find any examples whatsoever. Thanks!
  10. As discussed in this thread, I took a first stab at a Booster Pack for the 1.35" SHARP Memory Display. As suggested by @@greeeg, I added two footprints: FPC connector (on the back) zebra strip connector (on the front) While the outline is for the 1.35" variants (LS013B4DN01, LS013B4DN02, LS013B4DN04). The 1.28" (LS013B7DH03) and 1.26" (LS013B7DH01) displays should work too as the FPC cables are of similar length and zebra footprints are identical. The smaller, circular displays might work, but the length of the FPC cable might be too short. The larger displays have the same FPC ca
  11. While searching for a font creator I found an interesting one here: http://www.mikrocontroller.net/topic/99701#865331 It creates fontdata that are bit aligned so was a bit tricky to render but I have managed to create code that does that. By default it generates proportional fonts (from True Type) and also includes the top bit set characters that I need for my radio library. So, here is my initial code for rendering fonts generated by this utility - please note it is cannot handle fonts higher than 24 pixes. Add as font.h or to graphics.h: #include <stdbool.h> typedef struct F
  12. hello all! why are energia wire lib don't work? I have connected my launchpad 430g2553 to PCF8576 LCD 10. P1_6 to SDL and P1_7 to SDA . I try to write some code to use Software I2C Library but it did't work in energia . But EAR lib for software i2c work correct way. what i can to do to connect LCD with energia ? no software no hardware energia code don't work what 's the reason?
  13. I have few questions for users of LCD BoosterPacks.
  14. New LCD BoosterPacks are here. Both are 2.4" 320x240, one with touch panel, one without. Both feature the same pinout as their "little" 2.2" brother, same configuration options and SD socket. Can be used with my graphics library without any changes! Available on Tindie 2.4 LCD BP v3.pdf 2.4 LCD BP v2.pdf

  16. Hello, I have being working on getting a 20x4 LCD (HD44780) working on the CC3200 launchpad and have not been able to get it working. I have found a few posts with partial code and partial libraries but have not been able to find an SPI or I2C example that works. Does anyone have a working implementation of the HD44780 on the CC3200 in either I2C, Serial or SPI mode? This is seems to be the closest I have found ( https://github.com/remixed123/CC3200-hd44780-lcd ) ... but I am unable to get it working. If anyone has been able to get this working, could you send me a simple "hello wor
  17. Hello, I have a Stellaris Launchpad LM4F120XL Board and I am trying to interface with an 16x2 LCD. My LCD requires 5V and my Stellaris Launchpad has 3.3V output power pin. I have 2 questions, 1) Would it be alright if I connected the LCD to an external 5V supply and connected the data pins (D0-D7) to the Stellaris Launchpad GPIOs or do I have to have an LCD that operates on 3.3V supply? 2) Will it work if I connected the LCD to the 3.3V output power pin of the Stellaris Launchpad and connected the data pins (D0-D7) to the Stellaris Launchpad GPIOs ? Thank You
  18. This project attempts to control a surplus LCD (http://www.goldmine-elec-products.com/prodinfo.asp?number=G18246) using a MSP430 and the Stellaris Launchpad. Brief Description: This project is designed to run a 320x240 monochrome LCD with minimal CPU overhead. A seprate controller board supplies the VEE for the display, controls the Backlight and has a MSP430G2542 running as a SPI Master. The MSP also controls the clocks for moving the data to the display. The Stellaris side sets up a 1BPP offscreen display for Grlib and also sets up a UDMA job that transfers the display buffer to th
  19. Hi Has anyone successfully connected two TFT LCD displays to Tiva-C Launchpad? How much work would be to modify the graphics libraries to do so? Would two different LCD models be easier to do? I am aware that parallel connection is probably not possible due to lack of pins. Thanks for any suggestions.
  20. Does anyone have a link to a library that will let me use the two row 1602 LCD display unit with the CC3200 Launchpad? thanks
  21. MSP430F5529 has two I2C interfaces, using P3.0/P3.1 (SDA/SCL) and P4.2/P4.1 (SCL/SDA) and two SPI interfaces using P3.0/P3.1/P3.2/P2.7 (MOSI/MISO/SCK/CS) and P4.2/P4.1/P4.3/P4.0 (MISO/MOSI/SCK/CS). How, or rather maybe, what is the best way to access the non-default I2C/SPI peripherals, without resorting to modifying the Energia core? For instance, I am using the LiquidCrystal_I2C library found here, and it works fine on the G2553 and F5529, but I'd like to move the LCD over to the other I2C peripheral so I can use those pins for an SPI device. On Tiva, one can do "Wire.setMod
  22. Hello guys, I'm building a Holter ECG, and would like put one symbol on the LCD. Need to inform the user the level of charge that the battery has. And I would put the battery symbol so that information was given. But I am not getting, someone can give me an example of how I can put a symbol in a particular line of lcd
  23. Hey all, just wanted to share some code and a sweet picture of a QR code that was generated on an msp430fr5739: I'm working on a larger project that needed this functionality so I thought a proof of concept before I got too far into this was in order. While the pixels on the LCD I'm using (Nokia 5110 / PCD8544) aren't quite square, this code scans fine on my phone (Nexus 4). Anyways it uses the qrduino library to generate the code and some pcd8544 library for the lcd display. I briefly attempted to get this running on a g2553 but didn't quite manage it. The code is at https://
  24. I have a MSP430FR5969 launchpad with the Sharp 96x96 LCD boosterpack. The out of the box application had a splash screen. I am aware that using CCS with the library, I could display .c images using the MSP430 image reformer that is included with the graphics library but I'm not really good at coding in C. I came from the Arduino, so I'm more familiar with the energia. Is there any way to display these .c image files on energia?
