I am having some problems initializing the LCD . µC I am using is LM3s6965. It has to be initialized in 4 bit mode, since 4 pins are only accesible. these are the ports PA6/I2CSCL - LCD_RW PA7/I2CSDA - LCD_RS PB2/I2C0SCL - LCD_D4_KEYB_F PB3/I2CSDA - LCD_D5_KEYB_E PB4/C0 - LCD_D6_KEYB_D PB5/C1 - LCD_D7 PB6/C0+ - LCD_E This problem is a big pain in the ass.. I would be very gratefull if anyone could find the error on why it is not working. I am of certain it just a minor thing, but i have my doubts.. LCD init code (1).zip

Hello people, I'm doing a clock with MSP430g2553 chip.I need to make the text blink, each time I try set the hours, minutes, etc.. Example: HH... blink until I click in a button to jump to minutes; MM... blink until I click in a button to jump to seconds; can someone help me. Tanks in advance

I'm looking for comments and suggestions to make this more generally useful. I have a pile of surplus character line LCDs based on the Hitachi HD44780 chipset. There are oodles of these available surplus, and really cheap, like $2 cheap. The probelm I see for most modern MCUs is that the LCDs are usually 5V I/O (at least for the surplus parts) parallel and chew up a lot of I/O slow so they require a bit of code to poll the display or timed delays to insure reliable operation. I'm not too motivated to reinvent the wheel, but all the options I've found seem to miss a lot. I've seen the Ad

Here's what has been keeping me busy (apart from my real job) since just after Christmas - a timed camera remote. It is mostly code complete, although could do with a few tweaks here and there. The hardware however isn't quite finished as I'm still waiting for a few parts to be delivered before I can finally finish it - the most critical of which is the 2.5mm stereo plug to go into the camera. Consequently it hasn't actually fired my camera yet, but I'm confident it will work correctly when the final parts arrive. Background Many moons ago, I created a serial port remote release for my S

Always a sucker for displays of any form and shape I ordered one of the 1.35 inch SHARP LS013B4DN02 memory LCD when it made the rounds last year. At $20 apiece it's quite expensive for its size, but it's sooo pretty I finally finished up the code and published everything on Github. https://github.com/a...-memory-display According to the datasheet, this display runs on less than 15uW. I was not able to measure current with my lowly multimeter, so I'm pretty positive that the MSP430 plus display use way below 1mA. If the display looks familiar, that's because it was featured i

Hi! I am new to here. Several months ago I got a Launchpad with two chips 2553 & 2452 inside the box. I am really enjoying it except one thing: They have no LCD driver. Considering an external LCD module will bring terrible power consumption, I wonder if I can drive a simple 3 1/2 digits 7 segments LCD with very little power consumption. After searching the internet I found Maxim's 4 digits decoder ICM7211 might be a choice, but it is hard to access and so expensive that I cannot accept. Another choice is to use BCD to 7 segments decoder, finally I found 4543 BCD to 7 segments decoder

Greetings, Where can I buy 160/320 segment LCD? Suggest me any online seller for the same. Thank you !!

Hello, I am trying to interface my MSP430G2553 launchpad with an LCD (http://www.winstar.com.tw/UserFiles/ProductImages/12523136510757108108.jpg) but my characters look weird. I am using http://www.fibidi.com/arduino-lcd-16x2-characters/ with one potentiometer , with changing ports like this: #include <LiquidCrystal.h> // initialize the library with the numbers of the interface pins //LiquidCrystal lcd(8,9,4,5,6,7); LiquidCrystal lcd(P2_4,P2_5,P2_0,P2_1,P2_2,P2_3); void setup() { lcd.begin(16,2); lcd.setCursor(0,0); lcd.print("Hel

Hello, I try to write my own library for the MSP430G2553 and and the 2.2" ILI9341 display. I know RobG has made one but this project is basically for learning about LCDs and SPI. I took the code from http://www.elecfreaks.com/wiki/index.php?title=2.2S%22_TFT_LCD:_TFT01-2.2S and modified it for the MSP430G2553. It worked fine but only as solftware SPI. Now I want to use the hardware SPI. Here ist my code: #include <msp430g2553.h> #define LCD_MISO BIT1 #define LCD_CLK BIT4 #define LCD_MOSI BIT2 #define LCD_DC BIT0 #define LCD_CS BIT3 #define LCD_REST BIT5 void LCD_Writ_Bus

This is a heart beat counter, which displays the result on an LCD, it amplifies the signal by a dual op amp IC, and passes it to msp, as an interupt to count the number of pulse for 15 secs, it uses internal clock, so its not so accurate, but it will give you a good precised result... i have given all the neccassary information, including the schematic, the video link, and the code, with the header file.. here is its video... see the instructions to build it at http://www.instructables.com/id/Heart-Beat-Counter-using-MSP430/ lcd.h main.c

I got myself a mini-STM32 development board with a nice LCD with a touch screen (from DX, SKU 157301). The main reason I ordered it was that I read a thread on somebody's experiments with that kit (or a very similar one), and I thought it would be fun to play with. I thought the thread was here on 43oh forums. But now I can't find it, which is a shame, because whoever wrote that thread had a lot of experiments and things tested, which would be a great starting point. Oh well, I should have bookmarked it.

I've built a wireless temperature monitor with the following features: Very low-power (7uA) sleep mode Dual 1-wire dallas temperature sensor inputs, to measure two temperature sensors at the same time. A 2-line LCD display that displays the current measurement for 15 seconds when a button is pushed. 2xAA battery supply, with charge pump to power the LCD, temperature sensors and 433Mhz wireless module. Uses VirtualWire to transmit the data to an MSP430-powered receiver module. This is all currently sitting outside, and the indoor rx unit is uploading the measured temperatures as well as the -
Hi everyone, I'm hoping I can get some advice about my senior project. For my part of my project I have to connect my MSP430G2553 to an LCD display so I can display stuff like internal temperature and battery charge. I should be able to figure out how to read the inputs on my own. But my problem is that I have no idea which LCD to use. Its clear that it can be done with MSP430 devices, but how do I know which display to use with mine? Thanks

Hi all, Just to show off a little something I did It's an LCD display of a "ball" rolling around on a spotted surface, and bouncing from the boundries. The direction and speed of rolling is determined by the tilt of the entire setup. The hardware is a Nokia 5110 LCD breakout and a cheap 3-axis accelerometer breakout, both hooked directly to the MSP430 Launchpad. Code was written in Energia. Here's the video: I don't consider the code clean enough to publish, however I'll be happy to answer any questions about it. Happy coding!

Hi Guys, I found these http://www.rapidonline.com/Electronic-Components/Chip-on-Glass-2x16-Negative-Mode-STN-White-on-Blue-I2C-40x8mm-57-2332 and have ordered a couple. The interface is I2C and they can run off 3 volts. Handy if you are running out of I/O pins. I thought the price was pretty good, I wonder if anyone else has used them. The data sheet is very comprehensive so it should not be too difficult to get the 430 to talk to it (I hope). Before anyone asks, I don't work for Rapid Electronics, but I do spend far too much money with them :-( Hope this helps, Steve

Using the DHT Lib and an LCD I am about to get correct values to display on the LCD for between 2 seconds and 10 seconds, then the characters disappear. In the DHT library I had to change return NAN to either return 0 or return ERR to get it to work. I also had to change cli() and sei() to noInterrupts() and interrupts() respectively. I am controlling the contrast on the LCD using PWM fed through a capacitor. I am using the MSP430g2452 chip in a Rev 1.5 Launchpad. (I am at work at the moment, or I would post all the code.) My question is pretty simple: In setup(), I ha
