  1. For those who may not have seen it, the black LaunchPads with Rev B pre-release MCU are being phased out. New red LaunchPads with a revision C production device are replacing it. The announcement in e2e is located here. There is information on timing and compatibility with CCS located here. A quote from the second link: TI recommends that you update all hardware and software be updated to latest Revision C devices. Support for MSP432P401R on CCS cloud (dev.ti.com) and via MSP432Ware have been updated to match Revision C devices. Pre-production Revision C samples can be ordered online
  2. Has anyone been able to build an audio player with MSP432? I know there's a bunch of stuff for Arduino but it's all 8bit 19kHz stuff... I'd like to know if it's possible to build an audio player to play 16bit 44.1kHz wav files using an SD card and MSP432. Maybe someone has done it?? Or could something like this example for Arduino be ported to MSP? http://apcmag.com/arduino-project-5-digital-audio-player.htm/
  3. I noticed that if you use the TI arm compiler in CCS 6.x you can easily run code from ram. Unfortunately, it doesn't seem like they have implemented that for the arm-none-eabi-gcc compiler. Attached is a zip file project you can import into CCS. It is configured to run the msp432 at 48MHz using the high frequency crystal. It is also configured to generate small code using the nano.specs newlib configuration. In the default linker script, the data segment uses all the available ram starting at the base address of 0x20000000. The msp432 provides another bus address for SRAM at the base
  4. Hello everyone, I am a newbie here, just received my MSP432 launchpad few days ago and I'm willing to develop a wireless bluetooth communication between my MSP432+Bluefruit LE SPI and my computer. I downloaded the librairies from Adafruit that are designed for Arduino and I think I succeeded to convert a honest part of the code for Energia. Though, I still have an important problem that stops me to go forward. Indeed the Bluefruit LE SPI dongle communicate through some commands called ATCommand, and I don't succeed to transmit those commands through the dongle. As an example
  5. Hello Everyone, I am working with the MSP432 launchpad in Energia and I can't seem to use digitalRead() in and ISR? I'm hoping that someone can give me some indication as to why or find the bug in my code This is for a rotary encoder and the interrupts must fire on both Rising and Falling Edges. This Is why I try to determine the state of the pin that was just interrupted. The ISR's will be a bit more complex for the actual encoding but first I need to be able to read the state of the pins. Thanks Guys! const int encoder0PinA = 11; const int encoder0PinB = 31; volatile int
  6. Hello! I am having trouble getting the correct values from my MSP432 to my DAC. So basically my project setup is as follows: Transmitting: -Microphone connected to the A15 channel of my MSP432 -Xbee connected to the UART pins 3.2, 3.3 CODE Tx: const int MICAN = A15; // MIC in void setup() { Serial1.begin(9600); // baud rate setting } void loop() { Serial1.print(analogRead(MICAN));// send mic value over serial delay(100); // for testing } /////////////////////////////////////////////////////////////////////// Receiving: -MSP432 connected to my other Xbee d
  7. Hi, I am new to MSP432 and Xbee devices. I am trying to use the MSP432 and the Diji Xbee S1 to transmit and receive audio signals. However, I can't seem to transmit data over the Xbee. I just have the xbee module connected to pins: 3.3V, Ground, pin 3.3 transmitter and 3.2 receiver... I have confirmed that the Xbee's communicate using XCTU. Code: void setup() { Serial.begin(9600);// baud rate setting } void loop() { Serial.print("Failing");// send mic value over serial delay(100);// for testing } I can see the "Failing" showing up on the com port but not on the other
  8. I posted a blog entry about how I used the STM32L1 RTC (a few years ago) as a tickless, ultra-low-power timer for my RTOS. http://www.indigresso.com/_blog/?p=181 The MSP432 has a similar problem. Only the RTC and Watchdogs run in LPM3 and 3.5, no other timers do, but you want to use those LPMs for timed sleep! There is a workaround, and it is actually very fast thanks to the really great ALU in the CM3 and CM4 devices. My code is also implemented in bulletproof production firmware that I've shipped to various industries . Yes, the code is for STM32L1, but I think you should be able
  9. Hello, I'm trying to get a standard 1602 LCD (16x2 from Raystar) connected to MSP432 with the I2C interface. Are there any existing libraries which could help me out? I've found some I2C libraries for Arduino but naturally they're not compatible, and the only existing Energia examples deal with CogLCD which uses a SPI interface (emerging question: is there a way to make SPI and I2C compatible?) or standard 16 pin connection. MSP432 is still a relatively fresh chip, so I can't find any examples whatsoever. Thanks!
  10. Hello All, I've been visiting this site for a few days since embarking on using the MSP432 launch pad with the CC3100 booster pack. I'm really impressed with the energy and brain power of the folks here and hope to imbibe some of that smartness and in time help others that join here. I currently also use various Arduino and Netduino boards and having spent some time looking at the C/C++ source code I have come to realize (sadly) that my C/C++ skills (if one could call it that) are atrophied terribly. My interests lie in developing a bunch of "projects" using various MCUs and to eve
  11. Hi everyone. I am new to Energia, but I have used the Arduino IDE a bit. I am trying to use Energia to work with the MSP432 launchpads I just bought on sale, My environment is Ubuntu 14.04.3 LTS (trusty). I just downloaded the latest version of Energia from energia.nl (0101E0017). I ensured I have permission to access the serial ports. The only changes I've made is to select the tools -> serial port (when i had the MSP432 launchpad connected) and to select the tools -> board. I chose to run the example 'blink' code. When the MSP432 is selected I receive an error. When I chose a 4
  12. The TI nspire calculator is an advanced calculator which is expected to be the successor of TI-89. There are news on the web that a recent OS update (version 4.2) to the TI Nspire calculator added serial interface support to its programming environment. Before this OS release, the USB port is intended only for PC data connectivity (PC software for this calc is free with every purchase of the calc, and runs exactly the same as the real calculator on PC) and charging of calculator battery. Although this feature is not highlighted in the release notes, some calculator enthusiasts reported
  13. Hello i have to add an external memory card (sd card ) with my msp432 launchpad ..i am using energia..I have interfaced an environmental sensor and have showed the output via sharp lcd boosterpack..now i have to store the data which is temperature , pressure and humidity to the sd card ...I have no clue how to do it ...can anyone help ??
  14. While debugging my code this weekend I decided to step back and try to debug certain aspects of it. TI's Resource Explorer is a great tool with plenty of example code to look at and review. I was having issues with my WDT routine so I thought I would double check running one of the examples that was released, to be specific, I was interest in the WDT_02 example which can be seen here. The code was not working which really left me wondering since I assumed that any code published BY TI as an example MUST have been checked to see if it actually worked?! Well as it turns out the code does NOT
  15. Hello , my problem is , energia msp432 pin mapping allows 2 serial ports. Serial and Serial1. and msp432 have a 4 hardware serial ports. so i want to add one more serial port to the msp432 energia firmware. i open a topic e2e.ti.com but they didn't answer yet. so maybe somebody help me here. https://e2e.ti.com/support/microcontrollers/msp430/f/166/t/444248 in energia ide , msp432 hardware serial pins are p1_2,p1_3 and p3_2,p3_3. but msp432p401r also have a two more hardware serial ports. p2_2,p2_3 and p9_6,p9_7. if we look at the hardwareSerial.cpp file , last 2 lines HardwareSer
  16. Hi, Sorry for the repost, I save my preview topic in the wrong place I think (http://forum.43oh.com/topic/9286-msp432-servo-librairy-conflicting-with-pwm-analogwrite/, if someone can delete this one...). I am using an MSP432P401R launchpad Rev B with Energia 17 on Windows 10. I've recently got this issue: I can't control servomotors with the Servo.h librairy and at the same time send several PWM. As soon as I called the "attach" function from Servo, the others call to analogWrite in my code don't work anymore. I think it is due to some timer conflicts (both functions using A0 timer
  17. Hello I have interfaced Bosch BME 280 sensor via i2c with msp432p401r launchpad..and have displayed the output via 430 sharp96 lcd boosterpack..now I have to save the sensor output data to the internal memory...can anyone help ??
  18. I have interfaced Bosch BME 280 with my launchpad which is msp432 via i2c ..I am using energia ...I can see the output which is pressure, humidity and temperature through the serial monitor...now I have to show the output through this sharp lcd boosterpack...can anyone help ??
  19. I am having an issue with the ADC14 peripheral of the MSP432 on the MSP432 Launchpad using Energia. Background: I've used "ordinary" Arduinos in the past to get things up and running quickly for test fixtures or one-off devices, but for MSP432 and most everything else I do I prefer Assembly and C languages. I thought I would try my hand at doing something in Energia, to see how it compared. My test project was simply to characterize the ADC14 because it has decent resolution and that could be useful in other projects, so I started out with the basic AnalogReadSerial example and got it
  20. Hi, I just got a MSP432. I am working on Windows 7 64 bit. Upload to MSP430 does work, so I think Energia is o.k.. The problem are probably drivers. As upload did not work to MSP432, I updated to Energia 17, but this did not help. Then I updated drivers from: http://energia.nu/fi...110_drivers.zip This did not help either. I noticed that if I plug the MSP432, I get 2 virtual USB ports, not one as with MSP430, but this may be o.k.? From the utility xdfdsu -e I get following info about the drivers: ===================== VID: 0x0451 PID: 0xbef3 Device Name: XDS110 with CMSIS-DA
  21. I am trying to connect my MSP432 LP to a WIndows XP computer (having given up on using the Mac due to ongoing USB comms connection problems). I have downloaded and installed the driver package as instructed (XDS110_drivers.zip). The driver installation says it was succesful however when I plug in the LP for the first time, installation of the TI debug probes driver(s) fail. The comm ports drivers install correctly. During the driver installation these messages are shown: "Cannot Install the Hardware There was a problem installing this hardware: XDS110 ( with CMSIS-DAP
  22. Hello I have a msp432 launchpad and I have to interface it with Bosch BME 280 shuttleboard, I am not sure how to do it...ca anyone help please?? I have attached the shuttleboard flyer here...
  23. MSP432 Hi, For the MSP432, in the newer release of energia, is there a way to change from the internal clock to the high-frequency crystal oscillator? Or is there a way to set the DCO clock to different frequencies? (end goal is to use a reliable clock (to time up to 15 seconds) for interrupt control and spi communications) Thanks!
  24. MSP432P401R, Energia 16, Windows 7 64-bit Hi, I am using MSP432 in Energia and my analog input can only take a value between 0 and 1023 (10 bit) but the ADC should be 14 bit. How do I change this? In the MSP432 user manual table 20-1 shows different ADC14 Conversion Result Formats but I am struggling to convert this into Energia code. Thanks1
  25. This is a simple Energia library for the Texas Instrument TLC5615 Digital to Analog Converter, a 10 bit ADC. The TLC5615 library is located here. I recently took an online course based on the FR6989 and the C language that used this chip and thought I would implement in Energia. Here is a screenshot from my oscilloscope of the Energia version generating a sawtooth wave.
