  1. Hello I'm doing a projet using a MSP430G2553, a humidity sensor and a GSM module Sim800L. In the moment that i'm trying to upload my code, it gives me the following errors: c:/.../energia-1.8.7e21/hardware/tools/msp430/bin/../lib/gcc/msp430/4.6.3\libcrt0.a(_copy_data.o): In function `__do_copy_data': /root/mspgcc-20120406/BUILD/gcc/gcc/../../../gcc-4.6.3/gcc/config/msp430/crt0.S:195: relocation truncated to fit: R_MSP430_16_BYTE against symbol `__data_load_start' defined in *ABS* section in C:\Users\...\Envio_GPRS.ino.elf GPRS.ino.cpp.o: In function `__
  2. I made a heart rate sensor, and prototyped it with the launchpad. The mcu reads BPM and displays it on an LCD. I now want to create a pcb without the launchpad. I've attached what I have so far. I'm powering everything from a 9V battery, so I have a 3.3V regulator which I will use to power the MSP430G2553. Can I just connect the the output of the regulator to the VCC pin, and connect all the other pins to the circuit as I did with the launchpad, or are there other considerations I need to account for? Also, how do I debug and edit the program while the microcontroller is on my custom pcb?
  3. Hello, I'm try to use msp-exp430g2553et launchpad with energia but the serial monitor doesn't work. I'm using the example code:(One Wire DS18X20_temperature) I found it need to change RXD TXD but I changed it display "no more addresses" please help, thanks!
  4. I've dabbled in a lot of languages, but never made it to C or C++. Now, in the course of helping my son pursue a CS degree, I find myself learning Java. What, if any, are the options for programming the TI LaunchPads in Java? Opinions? (other than the expected "Java sux" :-(
  5. Hi, I wrote an article (in Portuguese) about how to use the SD16 ADC of MSP43F2013, and to show one practical application I transformed the MSP430F2013 in an I2C 16-bit ADC, similar to ADS1115. In the example, I read the data using one Arduino Nano. Comparing the conversion of SD16 and ADS1115: More details about the project can be found in my Github: https://github.com/agaelema/msp430f20x3_as_i2c_16bit_adc The project is open to further improvements/optimizations and functions.
  6. If you appreciate late 90s vintage PCs you might be interested in this one. I decided to build a Pentium II machine on which I can play my favourite games from those times. Magic Carpet (Bullfrog Productions) is one of them, but it needs a joystick. I had good quality USB joysticks, but those games need old analog gameport-based controllers that are serviced by the sound cards of the time. This new project acts as a USB Host and provides the analog output that emulates a 4 axis + 4 button game controller. the prototype works absolutely great, it takes about 0.6ms to read data fr
  7. Hey, i will use infrared first time and i don't know which infrared transmitter-reciever pair should i use? also which protocol should i use? can you suggest me a protocol and recever-transmitter pair please?
  8. I am looking for a library for sim800 and i am using energia compiler. I am working on certain project on which i suppose to interface sim800c with msp430G2553. i am doing basic coding of tcp/ip and http as well in that interfacing part. please suggest if there is any library available.

    Compile error

    Hello guys, I need help. I trust to program one LED with three Buttons on an MSP430, but when I compile the programme it shows an error. I have no Idea. In the following document you can see the code and the error report. Thank you. int R1 = P2_1; // LED Rot int G1 = P2_0; // LED Grün int Blau1 = P1_5; // LED Blau int T1 = P1_4; // Taster 1 int T2 = P1_3; // Taster 2 int T3 = P1_2; // Taster 3 int Time = 300; // Variable 1 int Zeit = 100;
  10. I am working on a certain project in which i would like to know that is msp430F2617 is compatible with Energia compiler or should i use ccs?
  11. Hi, Can anyone provide me the links or code for basic read and write example on FRAM of MSP430FR6989 on energia?
  12. printf in the IAR simulator outputs to the Terminal I/O window. Does anyone know how to output a single character to the window with only assembly? I tried sending bytes to the UART but nothing shows up. Any ideas?
  13. If you have one of those 5050/WS2811 aka WS2812 strips and you want to "wear" it, I have a board for you. Here are the specs: 20pin MSP430G2xx3 5V power supply 0.05" programming header UART input (allows pixel or sequence control) 11mm wide (0.45") 25mm long (1") 32mm long (1.25") - version with memory optional SOIC SRAM or EEPROM 1mm thick There are 4 boards on the panel, 2 with memory option. Assembled boards Board in the sleeve Board attached to 30 LED strip (0.5m)
  14. CoRTOS is a Cooperative Real Time Operating System for bare-metal applications. Its advantages over other systems are that it is fully documented with a manual and examples, is easy to understand and use and is astonishingly simple: The kernel is just 16 lines of C. The CoRTOS module compiles to ~200 bytes of code. The system includes optional modules implementing delays, timers, messaging, mutexes and signaling. It is intended for smaller microprocessors, such as the MSP430, Cortex M0+, AVR and PIC24, and for smaller systems of maybe a dozen tasks. CoRTOS is not a task sched
  15. This is a start to a bigger project and will be expanded on. Temperurature sensor for Mash -- MSP430, LM75B, possible other sensors, thermal couple. (working on code and proof of concept) Temperurature sensor for fermentation -- TBD Specific gravity sensor -- TBD User Interface -- TBD automation of pumps gas lines and equipment -- Requirements: Food safe, easily cleaned. probes and sensors sealed...... What I want is mash temp monitoring and logging to help me improve my brew days and procedure and maybe add a heater to keep
  16. Hey guys, I'm having some problems with my G2553 Launchpad. For some time now, the UART functionality has not functioned. I'm now sending the character "a" through the HW UART (Jumpers are positioned correctly) and what I get on my computer is completely different. I tried this in Windows 10, W7, macOS Mojave, even through the physical P1.1 and P1.2 ports to a Raspberry Pi and the result is the same. https://imgur.com/a/yd90MIw I also tried receiving data from a GPS module via UART and the data I received was unusable (the length of data was as expected, but the characters were
  17. Announcing the release PRTOS, an open-source preemptive real time operating system kernel for bare-metal applications. You may find PRTOS a good choice if you want to learn about preemptive multitasking. The API, though having all the features of FreeRTOS or uC/OS, is much simpler and easier to learn. Additionally the system will fit into much smaller processors. PRTOS is released by Cleveland Engineering Design - the developer of the CoRTOS cooperative real time OS, also available on Sourceforge. PRTOS presently supports the MSP430 and AVR architectures. PRTOS is availab
  18. Hello everyone, I am trying to get Energia running on my machine (macOS 10.13.3) and I am having troubles getting my serial ports to show up in the IDE. I have tried following the installation guide on the website here: http://energia.nu/guide/guide_macosx/ But when I click the link for "MSP-EXP430G2 and MSP-EXP430FR5739 LaunchPad," I am greeted with this: I know my USB cable is fine as I have used it with CCS on the Windows machines at school. If someone either has these drivers handy or if a dev from Energia has an expected time as to when these drive
  19. @REI VILO i think the RXD and TXD signal are inverted on the Pin map from MSP430G2XXX: http://www.energia.nu/pinmaps/msp-exp430g2/ For me on the launchpad MSP430G2553 TXD output from the chip is on pin P1_2, not P1_1.
  20. I'm new into the world of microcomputers and my first idea was to use an Arduino Nano, but then I found out that MSP430 can be programmed in a similar way (Energia) consuming less power while being equipped with an LCD controller. My question is now which series/model fits my needs. I want to drive 2 LCDs (6 digits each either this [https://www.mouser.de/datasheet/2/244/LCD-S601C71TR-1132196.pdf] or this [https://www.mouser.de/datasheet/2/244/LCD-S601C71TF-1133344.pdf] model) and use some buttons (max 10). According to Wikipedia I could either use MSP430x1xx, MSP430x3xx, MSP430x4xx,
  21. I am trying to add MSP430FR6972 in Energia. So far i have edited board.txt , board.mk but the pin_energia.h seems alot complicated than the previous two. So i need some help in doing so. I think the way i am adding a new board in energia might be wrong so just point me in the right direction and i will do the rest.
  22. I am using this code to communicate to the Nokia 5110 LCD display: https://gist.github.com/DmitryMyadzelets/83b6e1384a1ee35a7f5f Looking at the waveforms on an oscilloscope, I saw that there are only 2 to 3 clock cycles per write. For instance, the attached screenshot is when I write 0x44. The top waveform is the clock, the middle is chip select, and the bottom is MOSI. That doesn't seem correct at all. Shouldn't there be 8 clock cycles for transmitting 8 bits?
  23. Has anyone heard about Energia supporting the newest G2 MSP board? I ordered it and tried it with the existing board profile and it didn't work. I was really trying to get the rev. 1.5 board because I am tired of switching the jumpers every time i want to use the serial monitor.
  24. Hello, I would like to interface USB push notification board (bought recently) https://store.ncd.io/product/4-channel-push-notification-contact-closure-input-over-usb/ with MSP430 and interface multi sensors in such a way that whenever the sensor range is disrupted then actuator assigned to sensor will be switch on and this message will be sent on smart phones, I am new to this kid work and also if this thing will successful then I would like to make the actuators like rely board function with these king push notification any suggestion regarding making these kind solution through embedded s
  25. I cannot get this led to dim. It will flash on and off but no PWM as far as I can see. I copied the code right from the website here. http://energia.nu/Tutorial_Fading.html and wired everything the way it should be. Using a 220Ohm resistor instead of the 10k they had in there BOM. What am I doing wrong? I am using the MSP430G2231 chip and have all my settings in energia set accordingly I really don't know what I am doing wrong or if I have a faulty chip? Looking for someone to point me in the right direction.
