  1. I've got a pretty simple project, connecting an LIS3DH accelerometer to an MSP430G2553 (using MSP-EXP430G2ET). Here's the code: #include <stdint.h> #include <msp430.h> #define SLAVE_ADDR 0x19 int main(void) { WDTCTL = WDTPW + WDTHOLD; // Stop WDT __disable_interrupt(); // Just polling for now // Set to 1 MHz operation BCSCTL1 = CALBC1_1MHZ; DCOCTL = CALDCO_1MHZ; // Configure P1.6 and P1.7 as I2C SCL and SDA respectively P1SEL = 0xc0; P1SEL2 = 0xc0; // This byte is signed for some reason. P1.3 is the button input. P1DIR = ~
  2. Nick Gammon published an interesting post on using SPI on 16 MHz Arduinos to run WS2812 LEDs (aka neopixels) at: http://gammon.com.au/forum/?id=13357. He also provides a link with a lot of information about the NRZ protocol used by the WS2812 and tolerances: https://wp.josh.com/2014/05/13/ws2812-neopixels-are-not-so-finicky-once-you-get-to-know-them/. The tolerances are actually quite a bit looser than what I previously believed. So, I set out to do something similar with Energia and LaunchPads running at different speeds. Spoiler alert: It works. The previously linked articles provid
  3. MSP430 based Nixie tube clock. I was looking for some nice Nixie tube digit images so I could add them to my EduKit library, but I couldn't find any usable ones. I decided to just buy few of them and photograph myself. Then I thought that it would be a horrible waste if they just sit in a drawer. So here it is, my first Nixie project since... 1987. This clock will be available as kit, but since this is v1, I will most likely make some adjustments. Any suggestions are welcome.
  4. Edit 09.12.2016: I added Arial_16x24.h and Arial_24x40 (really a 24x36, but I had to keep a multiple of 8), digits only, created with GLCD Font Creator (I had to edit the result slightly manually). See images below. So I can confirm that adding any further fonts created with GLCD Font Creator works (I run it on Linux on wine BTW) and is only limited by how much fits into the SSD1306_OLED_5x8_11x16_16x24_24x36_fonts.zip
  5. Hello! I've got a problem when I want to show the output on serial monitor of a GPS. When I put a basic example (fade example) and the TX of the GPS on the TX of MSP430 (P1_2 pin) the output shows good, without any problem. The baud rate was the stock one (9600). When I try to make the same thing on other pins (I've choosed RX of GPS to P1_3 and TX of GPS to P1_4) a scrambled output takes place on the serial monitor and I don't really know what to do. I'll attach the code, maybe it's a code issue. Thanks in advance! I'm new in this so take me easy p
  6. Hello, I found an Arduino library for tea5767 module. Has anyone tried to import it on Energia IDE or at least has an idea about how can I do this? I work with msp430g2553. Please help me!! https://github.com/andykarpov/TEA5767
  7. I have to ask if someone knows better. If I have MSP430G2553 controller but in CCS I forget to change the settings for controller and there was chosen the G2453, which is the 8KB version of the same controller..does this somehow damage the controller when I program them? They seem to work but I am not sure if this can cause some surprises or failures as it may happen accidentally when using different controllers??
  8. The goal of this project is to utilize an MSP430 to allow existing remote-controlled outlets to by controlled over Wi-Fi. As purchased, the outlets can be controlled with a provided remote control which uses 434 MHz radio signals. By programing the MSP430 to replicate the signals from this remote and hosting a web page with controls on the MSP430, the outlets can be able to be controlled from anywhere on the same Wi-Fi network. The completed project provides a web page that can both control each of three outlets individually or all three at once. This is done using an MSP430 as a controller wi
  9. Hi... So let me ask this straight. I have to run a 3phase BLDC Motor using a full bridge inverter. The PWM signals for the switches of the inverter need to be generated using a microcontroller. Which means I need 6 different PWM signals. Can this be achieved using an MSP430g2553 chip? I currently have the 20 pin version only. I happen to be a complete beginner in the matter of microcontrollers. So please be kind enough to overlook my dumbness if I've missed out something very obvious!
  10. Hi all. I have been working on a fingerprint based project using adafruit's fingerprint scanner from here http://www.adafruit.com/products/751 . I have been successfully using this with Arduino uno with the help of the following library provided by adafruit itself, from here: https://github.com/adafruit/Adafruit-Fingerprint-Sensor-Library Now, i have to switch from Arduino to Msp430g2553 LP. Can you'll please guide me with the following? : 1) How to port This library to Energia? I know the basic part is to replace Arduino.h and associated code with #include <energia.h
  11. I am trying (for quite long time) to write to EEPROM 64 bytes of data in 4 chunks (as EEPROM's page size is 16 bytes). Unfortunately, the MCU sends few extra bytes every time it transmits. For example, if I send 16 bytes, it transmits 22, with 6 last bytes being of unknown origin to me. For example, I send 15 text bytes within for(...) cycle xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx but see on the scope xx xx xx xx xx xx xx xx xx xx xx xx xx xx xx BF F6 FD D7 3A C0 I tried another approach: send 15 bytes + 00. My program stops at 00, then I try to replace 00 with wh
  12. So I'm working on a fingerprint scanner project with this repo written for arduino for the scanner I'm using. I am trying to make it work with an MSP430G2553 instead of the Arduino Uno. When I try using this library in Energia, it can't find the scanner despite being wired on the launchpad the same way that it is wired on the Arduino (External 5V source, Arduino pin 2 --> MSP430 pin 1.1, Arduino pin 3 --> MSP430 pin 1.2). The code compiles and the serial monitor outputs the test looking for the scanner, but it has yet to be able to find it. If anyone could give me any help with this, it
  13. Overview dAISy (do AIS yourself) is a very simple AIS receiver that I developed from scratch. It is built around the Silicon Labs EZRadioPRO Si4362 receiver, using a Texas Instruments MSP430G2553 MCU for processing and the MSP-EXP430G2 v1.5 LaunchPad as development platform. The complete project source code and schematics are available on GitHub: https://github.com/astuder/dAISy Update 5/18/2015: A finished, self-contained AIS receiver based on this project is now available for purchase in my web store. AIS, short for Automatic Identification System, is a standard for tracking ship
  14. Hello fellows, I need some help, i have get a code http://store.43oh.com/download/uploads/TheTerminal-OLEDDisplay/code/GWDeveloper-OLED_MSP430_USCI.zip. Now I have made some changes and I get the code working correctly, This display shows 4 lines of 8 pixels each, the code is implemented to work with a 6x8 font that is displayed correctly. I need to run a larger font, can anyone help me to rewrite the source code correctly that allows me to view a larger font correctly.
  15. Can anyone help me to transfer the data from msp430g2553 to CC3200? I want to know how to interface these two modules
  16. Hello. I have wrote an Energia program for digital potentiometer control. I want to save variable "counter" (it is an integer number from 0-255) in non-volatile memory using mspflash.h library in case of reset or power interrupt. But it doesn't saves. I am allmost sure there is something wrong with initialization of variables or pointers inside my code. Can anyone help? Any improvements in code? My code: #include <SPI.h> #include "MspFlash.h" #define outputA P2_1 #define outputB P2_2 #define flash SEGMENT_D int aState; int aLastState; const in
  17. Hi Guys! I have MSP430 EXP LauchPad for my course. I want to program this lauchpad on Linux Mint but I have some troubles about that. Firstly, I downloaded Code Composer Studio to work on it but I had a error about port FET. Now I decided to download Energia, it looks like arduino IDE that is why I know about cart and port settings. My trouble on Energia is on the picture:
  18. This is my first attempt with Energia. Sorry to ask so many questions. I need to know what state the G2553 is left in after whatever Energia does to it automatically so I know what I need to do, such as: Does it set the top of the stack? Does it set the clock to 1 MHz? 8 MHz? Does it disable the watchdog function? Does it return P2.6 and P2.7 to GPIO use? Does it leave all port pins as inputs with PU resistors? Does it set up a timer to generate interrupts for millis()? Also, where can I find this kind of information? I didn't have any luck searching for

  20. Hi, I am completely new to serial communication. I wish to use a high speed ADC from TI ADS 8361. I want to interface with msp430g2553 using energia IDE. Can I get some code to check the ADC functions.
  21. I believe to have all connections correct from the launchpad to my breadboard, but when I connect VCC to my board the LCD just flickers some vertical lines and then the LCD goes dark again. Anyone have an suggestions? /* The circuit: ================================= LCD pin Connect to --------------------------------- 01 - GND GND, pot 02 - VCC +5V, pot 03 - Contrast Pot wiper 04 - RS Pin8 (P2.0) 05 - R/W GND 06 - EN Pin9 (P2.1) 07 - DB0 GND 08 - DB1 GND 09 - DB2

    MSP430 GPS

    Hi, Is there any GPS library for energia that supports MSP430g2553? TinyGPS++ doesn't seem to work. Please help. Thank you.
  24. Hi, When doing offset calibration for pH sensor in Arduino we bring pH 7 to 2.5V as Arduino analog output is 5V. Does that mean when the same is done with msp430g2553 the voltage be adjusted to 1.5V as msp430g2553 analog pins output around 3V only? When I tried adjusting the pot I could only bring it to a minimum of 2.5V with msp430. Does anyone know why? Thanks.
