  1. Hello everyone, i was exporting a library from arduino when i realized i needed a sleepMicroseconds alternative for delayMicroseconds. is there one? Thank you.
  2. Hi, I am not familiar with CCS and a novice in TI Launchpads. I have written an Energia code and would like to burn it into CC3220SF launchpad Flash memory so I could execute the code while disconnected from PC USB. I looked at e2e.ti.com/.../2495478, but did not work for me. Could you please guide me achieve this? Thanks, Sam
  3. Hi Fellow Energians, I am developing a product using Energia connected to a CC3200 Launchpad. The ultimate product will not use a launchpad, but will use a CC3200 processor. How does one download from Energia to a custom board? Thanks, Paul
  4. Hello Group. Is there any way to change the color of comments in a sketch? The default grey color is very light and hard to read on my Acer computer and I would like to make it darker and maybe a different color. I tried changing to a different font and that helped a bit. Thanks for your help, Paul
  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 please //THE CODE https://pastebin.com/cjFyjHns #include <SoftwareSerial.h> static const int RXPin = P1_4, TXPin = P1_3; static const uint32_t GPSBaud = 9600; // The serial connection to the GPS device SoftwareSerial ss(RXPin, TXPin); void setup() { Serial.begin(115200); ss.begin(GPSBaud); } void loop() { // Output raw GPS data to the serial monitor while (ss.available() > 0){ Serial.write(ss.read()); // delay(10); } }
  6. I have found a very simple LCD display "DfRobot LCD for Arduino with rgb backlight". It seems like a good way to have a display with projects but the problem is that for some reason Energia cannot process the code. No matter how I try, i just get an error message: Error compiling for board MSP-EXP430G2ET w/ MSP430G2553. Is there any way to use such displays with Energia? the code is very simple #include <Wire.h> #include "DFRobot_RGBLCD.h" const int colorR = 255; const int colorG = 0; const int colorB = 0; DFRobot_RGBLCD lcd(16,2); //16 characters and 2 lines of show void setup() { // initialize lcd.init(); lcd.setRGB(colorR, colorG, colorB); // Print a message to the LCD. lcd.print("hello, world!"); delay(1000); } void loop() { // set the cursor to column 0, line 1 // (note: line 1 is the second row, since counting begins with 0): lcd.setCursor(0, 1); // print the number of seconds since reset: lcd.print(millis()/1000); delay(100); }
  7. Just installed in the latest Energia and then used the board manager to update my msp432r stuff to the latest 5.29.0. However, in: AppData\Local\Energia15\packages\energia\hardware\msp432r\5.29.0 the platform.txt file says: version=5.25.2 version.string=5252 Is 5.29.0 the same as 5.25.2?
  8. Hello I need help. I have to get it with an Energia programming that you have to press a button 5 seconds before the led tackles. Are there any programs or commands on how to get this?. Thank you for your help
  9. Hello, I am storing a sensor value in the Flash Memory in a Segment of MSP430F5529 board. Since the data from the sensor keeps changing i want the data to be overwritten so that not much of space in flash memory is used. Is there a simple way to achieve the overwrite feature in flash memory ? Also i have another doubt, i wanted to know if i keep writing continuously a data to flash memory, does the microcontroller gets caught in writing to the flash and slows the running program ? thank you for taking time to review my questions.
  10. Hello, Has there ever been a method developed for Energia that allows it to use an external crystal? I'd like to have the ability to enable a low frequency crystal as well as a high frequency crystal on the msp430fr5994. Does anyone have any recommendations for implementing this? Thanks,
  11. Hello, I'm trying to get some code to upload to my MSP-EXP430F5529LP board. Following this forum post (I'm on Mac OS Catalina), I installed a pre-release version of Energia, and I get this error: Energia: 1.8.10E22 (Mac OS X), Board: "MSP-EXP430F5529LP" Sketch uses 706 bytes (1%) of program storage space.

  12. Hello, I've been developing with the msp430fr5994 on energia and I seem to have come across an issue using the serial ports on 6.0 and 6.1 I have two of these processors connected together with the Tx/Rx connected respectively on 6.0 and 6.1. I have the first processor sending out a single number using the Serial1.write("1"); command. The second processor i set to respond by displaying data on it's TFT once it gets any kind of data. So far, I can't get anything to come out of the Serial1 ports. An oscilloscope shows that it's being held high and not sending any kind of data out. I've tried just about every combination of Serial1.print and Serial1.write commands and attempted single numbers, letters, phrases, ect. I read online from about a year ago that there was an issue getting Serial1 to work on this processor using energia, was there a fix for this? Thanks,
  13. Howdy, I'm having trouble programming my MSP430FR2433LP with Energia on my Mac. When I try to upload the program, it gives me this error: MSP430: Error initializing emulator: No USB FET was found. Strangely, I am able to program it with the online Code Composer Studio. I have made it blink red and green lights. Unfortunately, I'm not trying to become an embedded programmer (while that would be fun, I do not have the time) so I do not want to learn CCS, registers, and serial communications in pure C. Props to all you who can do this. I really want this to work with Energia - it will save me many hours down the road. I also tried this on my Windows Parallels desktop emulation software (which works pretty damn near perfectly like a true Windows OS), but I got the same error message! The board and USB cable are clearly working if I can program with CCS. So what is going on with Energia? Thanks, Another Mac-using engineer with problems
  14. I an using mspexp430g2 launchpad on energia with windows 10 OS.In this while compiling the inbulit "DigitalReadSerial" example code from energia IDE ,at that time it should print the output in the Serial Monitor screen . But it does not print anything.Please help me.
  15. I want know why my code isn't work, I used to use in TM4C129 and edit the code to used in TM4C123GXL, but it doesn't work. #include <stdint.h> #include "driverlib/sysctl.h" #include "driverlib/qei.h" int pos; void setup() { Serial.begin(9600); // Setup QEI Module SysCtlPeripheralEnable(SYSCTL_PERIPH_QEI0); GPIOPinConfigure(0x00031806); //GPIO_PD6_PHA0 GPIOPinConfigure(0x00031C06); //GPIO_PD7_PHB0 GPIOPinTypeQEI(GPIO_PORTL_BASE, GPIO_PIN_1 | GPIO_PIN_2); // Configure and Enable QEI QEIConfigure(QEI0_BASE, (QEI_CONFIG_CAPTURE_A_B | QEI_CONFIG_NO_RESET | QEI_CONFIG_QUADRATURE | QEI_CONFIG_NO_SWAP), 2147483648); QEIVelocityConfigure(QEI0_BASE, QEI_VELDIV_1, SysCtlClockGet()); // Divide by clock speed to get counts/sec QEIEnable(QEI0_BASE); QEIVelocityEnable(QEI0_BASE); } void loop() { // Report Position & Velocity of Encoder to Serial Terminal Serial.print(QEIPositionGet(QEI0_BASE)); Serial.print(','); Serial.println(QEIVelocityGet(QEI0_BASE)); delay(10); }
  16. With the 5.25.0 msp432pr board file update, my SPI stuff has stopped working. Some time back, there was an issue with spi modes 0/1 being switched. As such, that was the direction I was looking to try and figure out my current problem. While digging around I noticed this: 5.23.1\cores\msp432r\ti\runtime\wiring\SPI.h #define SPI_MODE0 SPI_POL0_PHA0 #define SPI_MODE1 SPI_POL0_PHA1 #define SPI_MODE2 SPI_POL1_PHA0 #define SPI_MODE3 SPI_POL1_PHA1 5.25.0\cores\msp432r\ti\runtime\wiring\SPI.h #define SPI_MODE0 SPI_POL0_PHA1 #define SPI_MODE1 SPI_POL0_PHA0 #define SPI_MODE2 SPI_POL1_PHA1 #define SPI_MODE3 SPI_POL1_PHA0 If I swap the definitions for SPI_MODE0 and SPI_MODE1 my code works again. So has the mode swapping problem re-appeared?
  17. Hello, I am playing around with msp432e401y launchpad in Energia and in my case analogWrite() does not work. I am not confident what this behavior is not related to my system, so I would like to get confirmation from other forum members. Thanks
  18. Hi, rank TI n00b here: I am a professional developer working a often in the Arduino IDE with Atmel, ESP, ARM, ATtiny and Kendryte processors among others. I am replicating a client design centered around an MSP430G2302 (14 pin TSSOP versus the apparently several different pin counts for this model) and thought the Launchpad MSP430GET would be a good programmer as it claims to support the MSP430G2302... and Energia is very familiar to me as it is essentially the Arduino IDE. I am finding no way to access the MSP430G2302 from Energia, nor any way to specify a 14 pin vs 16 pin package. Is this IC supported, and if so how do I use it? If this is one of those things where I'll get asked 'would YOU like to support it'; then I can assume it's unsupported despite what the literature claims. I am ready to pay the premium for using an ATMEGA328P-AU in order to be able to move on from trying to make this work to getting on with programming and designing this product. Thank you
  19. When installing energia on Linux Ubuntu the install runs successfully and produces a desktop icon and a menu item. The problem is that both launchers point to "/home/$USER/Downloads/energia-1.8.7E21/arduino" - but the file "arduino" does not exist in the energia directory so the app will not launch.
  20. I am using MSP432P401R and wanted to increase the I2C frequency from 100kHz(Standard) to 400kHz(Fast). In the Wire library for arduino, there is a function Wire.setclock(). Has anybody written such a function for energia? Because it is not there in energia. I went through the wire and twi libraries and found the following, In wire library, Wire.endTransmission calls a fucntion in twi library, twi_writeTo() which has the following line of code, UCBzCTL1 |= UCSSEL_2; // SMCLK Is this the line of code that sets the clock speed? Also in the twi.h library, the line of code, #define TWI_FREQ 100000L defines the frequency as 100kHz, but even if I changed it to 400000L, I don't see any change on hardware. Is this the right way? I'd appreciate if anyone can help me with this. Thanks
  21. Hi Everyone, I'm looking for ILI9340C library so that I can import that library in Energia and burn a program on TIVA C series. I read some of the forums on this websites but some people are using a different launchpad and some are using ILI9341 or some other LCD. I need to work with TIVA C launch pad and ILI9340. I'm using Energia. Before that I was Using Keil uVision to make some libraries for TIVA C Launchpad to work with ILI9340 but that were not that much efficient. I read some of you successfully made libraries to work with TIVA C launcpad and ILI9340 but links provided on those forums are not working or the content from those links have been removed. So please help me. Thanks.
  22. There's a problem in interfacing Neo-6m GPS module with CC3200 MCU. I have to interface with Neo-6m GPS module with CC3200 MCU for getting the coordinates of a particular location. GPS module works fine when I interface it with Arduino UNO/Mega/Nano. Before I bought my own CC3200 MCU, I had interfaced Neo-6m GPS module with CC3200 at an Industrial training Institute and it worked fine there. Now, when I'm trying to interface GPS module with same configuration, setup and program, it shows nothing on Energia's Serial Monitor. Please check video (attached). Please let me know whether jumpers and wires are connected correctly. VID-20190629-WA0002.mp4
  23. Hi, I am trying to use Energia with EK-TM4C1294XL, but I am unable to install the right LaunchPad board on Energia. I downloaded the proper driver usinghttp://energia.nu/guide/guide_windows/and downloaded Energia for Windows using http://energia.nu/download/. As a point of reference, my computer is Windows 64 bit. I then usedhttp://energia.nu/guide/boards/ to install the right LaunchPad board, but I am receiving the following error message shown below. I tried all troubleshooting suggestions on the links provided, but I can’t seem to find a solution to my problem. Can you help me determine the cause of this and help me resolve it?
  24. Hi, Does energia IDE support programming a MSP432 microcontroller on a custom board (by JTAG, SWD or UART) ? If not, what are the hardware modifications needed to support it? In the Energia website I can only see that the launchpads are supported https://energia.nu/guide/install/macos/ Regards and thank you
  25. I'm trying to get Energia21 working with my MSP432E (which I'm still struggling with) and ran into a problem. The platform.txt file references dslite 7.2.0.2096. However, to get this version of dslite, I must install the TivaC board...which installs this version of dslite in .../Energia15/packages/energia/tools/dslite. It seems like there is a mismatch between the dslite version that the v5.19.0 msp432e board is installing and the platform.txt file jrd PS FWIW, now that I fixed this, I get a "Frequency out of range error"...I tried other versions of dslite (6.2.1.1594, 8.0.0.1202, and 8.2.0.1400) to no avail.
