  1. I am developing a timeout / soft timer library for the MSP43x and would like to share it with you. It's still in the initial version, but all the functions are working. I'm developing and testing on MSP430F6736, but it worked fine on launchpad EXP430F5529LP. The library uses a timer to periodically generate ticks. In the base version developed by Felipe Lavratti, the timer-tick occur every 1us through a 32-bit timer (ARM Cotex). To avoid overloading the CPU I modified the code to accept longer time intervals and also functions to automatically calculate the Capture / Compare value of
  2. Hello , I'am trying develop a data logger to send data to a device through bluetooth, but in my state machine i want make a state were I can verify if the bluetooth is paired with smartphone, does anyone can help me , i don't have idea how can I do this.
  3. Hi, I posted a question on e2e but I found interesting to ask here too. I'm trying to port the Adafruit MCP4725 library to MSP430 using the Driverlib. I'm testing with launchpad EXP43FR2433 running at 1MHz and I would not want to use interruption to keep the code more portable. The sequence to write some value on DAC is relatively simple. - Set address -> send start -> send write cmd -> send upper byte -> send lower byte -> send stop. Using the following code one byte of the value is lost. msp43x_I2C_setSlaveAddress(EUSCI_B0_BASE, _i2caddr); ms
  4. I am working on power factor and energy monitoring. I would like to know if there is any library available in energy monitoring for energia using MSP430. If exist please send.
  5. Hi all, I am trying to connect SPI flash (W25Q80DVSSIG-NDhttp://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/166/w25q80dv_5F00_revf_5F00_02112015.pdf) to MSP430g2553 launch pad. Here I made the connections as below P1.1 SOMI <---------- 2nd Pin DO P1.2 SIMO ----------->5th Pin DI P1.4 SCLK ----------->6th Pin CLK P2.0 SS ------------>1st Pin CS I tried to use example code from TI to get the manufacturer id and device id. But I am failing to receive the expected data. Please have a look into my code and
  6. Hello, I'm using energia 1.6.10E18 with the launchpad MSP430G2 and the MSPG2553 installed. So I saw that in another forum the library from cactus.io was used for the BME280. That library was for the I2C. Now I want to use the SPI library and they had one.(http://cactus.io/hookups/sensors/barometric/bme280/hookup-arduino-to-bme280-barometric-pressure-sensor-spi). So I installed the library changed it to hardware SPI with the cs pin on P2_1. And it compiled, but i'm only getting these results: 813.81 mb 100.00 % 0.00 *C 32.00 *F 813.81 mb 100.00 % 0.00 *C
  7. Hi All, I am trying to create a transmitting and receiving node. My setup is as follows My transmitting node #1 is mbed-K64F with cc1101.(working fine sending data) My transmitting node #2 is msp430g2553 with cc1101.(giving me challenges) My receiving node is mbed-lpc1768 with cc1101 (working fine and received data from node #1) my connection for msp430 are as follows: csn is at pin 8 sck is at pin 7 mosi is at pin14 miso is at pin 15 I just declare csn as output, the rest of the pins i assume gets configured when we call spi.begin()?
  8. Hello, I'm using IRremote library and IRrecvDemo is working perfectly, however IRsendDemo is not working. I've commented out these lines in IRremote.cpp //pinMode(TIMER_PWM_PIN, OUTPUT); //digitalWrite(TIMER_PWM_PIN, LOW); // When not sending PWM, we want it low and removed the if (Serial.read() != -1) condition, but it is still not working. Do you have any idea what might be the problem? Thanks.

  10. Hello ,I'm using MSP430F5131 Microcontroller of TI.I also use a MSP-FET Emulator in order to program that device.i have written a code in Code Composer Studio (Defined the properties of CCS's project to the devices im using).I compiled the program and no errors has found.Then i connected the MSP-FET to the board according to the datasheet SLA138H , page 26 . (The board supplies the 3.3V so i connected it to pin 4 in the JTAG connector of the MSP-FET). I didn't connect the TEST/VPP and didnt connect the the resistor R2 330Ohms as instructed in that datasheet coz i dont need to use the fuse blow
  11. Hi everyone, I am new here so please forgive if I am posting this in the wrong place. I am trying to develop a simple game (snake or tic tac toe) using the boosterpack mkii and MSP430FR6989 but I am having terrible hard time even getting started with the project. I would also like to know which libraries to download and etc. There are a lot of tutorials for boosterpack mkii but none of them use the FR6989 board. If someone could get me started and guide me the right way it would be really appreciated.
  12. In case you need to stock up on MSP430 dev boards, it's MSP430 week in the TI store. http://www.ti.com/store/featured/msp430week18.html
  13. Hello Guys Good Day for All, I just open the Mspflash example from energia example using MSP4305969LP board. But when I compile, it show error as below picture. Any one can help me? Thanks a lot. Best Regards, Lukman
  14. Hi All First, I would like to thank @Rei Vilo for providing the Library for the Kentec (BOOSTXL-k350qvg) library with Energia. I copied the code out of https://www.youtube.com/watch?v=XyeUpk6P4kA (as I didn't find the powerpoint or pdf) and got it to work with an MSP430F5529 launchpad. (Energia 18, Windows as the Mac version doesn't work atm). Then I compiled the same code on a MSP432P401R launchpad and it runs a lot slower than on the F5529 (I assume this is a known issue, due to slow SPI speed ( https://github.com/energia/msp432-core/issues/27 ) but also doesn't look the same, the
  15. Hi, I have an MSP430G2553 board that I need to work with. However, when using Energia, the program usually freezes or becomes extremely slow to the point that I just have to terminate the process and close it. I really doubt it's a code problem, since the only codes I've used have been from the Examples (Blink and AnalogReadSerial). I've tried a couple of things: uninstalling and re-installing drivers, following all the steps in the Windows guide for Energia, re-downloading Energia. But nothing works. The problem is most certainly a communication problem with the board since, upon un
  16. I just started playing with the MSP430 with the G2553 chip and am having problems with interrupts. I have the following code just for testing and sometimes pressing the button works and sometimes it doesn't. I thought maybe I had a bad board and replaced it but I still have the same problem. I am beginning to think I am just doing something wrong in the debugging or something. But, here is my code: #include <msp430g2553.h> #define LED1 BIT0 int main(void) { WDTCTL = WDTPW | WDTHOLD; // Stop watchdog timer BCSCTL1 = CALBC1_1MHZ; //Set DCO to 1Mhz DCOCTL = CAL
  17. Hello, I'm currently working on a project temperature data logger. Now I'm using mc: MSP430f5529 I integrated with sd card using the petit fatfs library. Due to some limitation, i cant use full functionality. so I'm planning to make it work on fatfs. but there is no footprint for that. can you help me to come out of this issue? Thank you, sir Limitations: 1. Cant create a file 2. while saving the data in the same file previous entries are all given garbage value at sometimes. because it is not an empty file filled with null.
  18. Hi! It's my first time using MSP430 and I'm a little bit lost . I want to connect a barcode scanner module with the MSP430. In order to do that, I need an USB port extra. I know that Arduino has a USB Host shield, but MSP430 doesn't have any shields, does it? So, how can I do it? Is there any way to use the USB Shield of Arduino for the MSP430? Thanks!
  19. Hi All, I need to compile and run c++ codes and .ino codes I have for my device. Since these codes interact with each other, I need to write a script to compile and run them from a terminal window rather than compiling and uploading my .ino code from the Arduino IDE ( Energia). Can someone help in this regard? I use Mac OS, but I am fine to switch to Windows if necessary. I use MSP430G223. Thanks Navid
  20. Hello, I hope this is the right forum to post in, I'm a new user here... So, I have been trying to get the RFM12b module to work with my MSP430F5529. The connections are as follows for transmission: VDD --> 3.3V GND--> GND SDO-->P6.5 nIRQ-->P3.4 nSEL-->P3.3 SCK-->P1.6 SDI-->P6.6 Now, I have the following code, in which I only configure the module and try to read its status register: #include "main.h" void WriteCMD(unsigned int CMD); void Write1(); void Write0(); int check_status(); void main()
  21. Hi , I am using MSP430FR4133LP , in energia the GPIO pins are predefined in the pins_energia.h for MSP430FR4133 LP based on the silkscreen on the board. I using this MSP430FR4133 chip for another project and in that i am not using a LCD so i thought that i can also use LCD pins as GPIO. For this purpose i need to add the pins in the pins_energia.h but i am not able to crack it. Can anyone help me with this ....? if i try to use any other pins other than the defined ones (say P2_2) ... it throws an error as " P2_2 not defined in the scope" // Pin names based on the silkscreen

  23. I worked on a new servicing routine for my kit oscilloscope's quadrature rotary encoder, and decided to write it all up and post it on Github. Included are routines for periodic polling and for pin-interrupt servicing. Hardware switch debouncing is not needed. The routines are for general use, but I wrote testing code for the MSP430G2231 installed on the Launchpad. The scope guys have used the "lookup table" state transition routine that most people use today, but it doesn't work very well on the scope, and I haven't found it to work very well generally. My routines are designed to avoid
  24. A while back @omnicron generously offered up some surplus boards sporting a MSP430F149 and a good mix of conditioned I/O on the board including a couple of 5.8psi pressure transducers. I feel that this, along with the programming header on the board, makes it a good all-around board for general purpose projects. The board also supports a standby NiMH battery (6v, 1800mAh) with charging/discharging capability and voltage monitoring all controlled by the MCU. The battery switches in via a relay upon primary power loss. One of the pushbuttons is configured in hardware to be used as a soft power
  25. I'm trying to replicate the project shown here http://www.mjlorton.com/forum/index.php?topic=284.0 but instead of the g2211 I'm using the g2152. I somewhat understand what the code is doing, however I'm having a hard time setting up the timers and capture compare registers. Additionally I'm not sure how the timer/ccr is being used to differentiate between a long or short button press (is it using nested interrupts?) The original code uses grace included configs which obviously aren't there,I'm trying to infer how things were set up originally. I have the gpio and wdt config figured out but not
