  1. Hello people, I'am trying use a SDCARD only to regist data. All my project was made with "MSPClassic Registers", so I saw in the forum a Bluehash post, but was in CMSIS, in mode to satisfy my project I try to change some files. Now I have some problems to finish him there is someone who can help me?I need Something very simple, just confirm if the card is loaded or not and save data Conections: * P4.6 - CS (active low) * P1.6 - MOSI UCB0SIMO * P1.5 - CLK UCB0CLK * P1.7 - MISO UCB0SOMI FILES: spi.c lcd.c lcd.h main.c main.h
  2. Hi, I'm trying send GPS (adafruit Ultimate GPS FeatherWing) coordinates to another location using XBees and then displaying GPS data on an LCD (Sharp 96 Booster Pack) using Energia. This involves 2 pairs of Xbees (4 total 2 different ranges), 3 MSP-EXP432P401R (Black Version), the GPS and the LCD. I wrote some code for the first MSP432 on getting GPS data and getting it to the XBee to transmit to another MSP432 (connected to 2 XBees). Although I haven't been able to test it (GPS and XBees aren't here yet) I feel like it will at least be close if not functional.GPStoXBEE.ino After
  3. Hi I'm new to using both the MSP-EXP432P401R (Black Version) and Energia. I want to attach a GPS (adafruit Ultimate GPS FeatherWing https://www.adafruit.com/product/3133) and an XBee to the micro-controller so I can send GPS data to another MSP432 micro-controller with an XBee. I see I can attach the GPS or XBee to the hardware uart pins 3.2(Rx) and 3.3(Tx) their listed as pins 3 and 4 respectively on the Energia Pin Map (https://cloud.githubusercontent.com/assets/951776/15053945/5f47bac6-1305-11e6-9ab5-c71d425194ce.jpeg) but where can I find two other hardware pins for attaching a second
  4. Hello fellows, I need some help, with a situation, I want convert some analog signals to digital and send him by the UART communication, but I dont get how to solve this problem. my digital values is represented by "tempADC" variable, soo how can I get a buffer with values to the pc with UART communication. I try many things, but i dont understand how to put my output signal in the terminal in this format. temperature: 40º temperature: 41º temperature: 42º temperature: 43º can anyone help me?! my code: #include "uart_Tx.h" #include "stdio.h" void UART_TxConfig
  5. Hello guys, I have been trying to connect my MSP432R Launchpad with another device that requires 57600 bps on Serial1 and after hours trying to find an error in my code I decided to test the Serial1 port. Thus I uploaded the following test code and connected RX to TX (P3.2 <-> P3.3) : void setup() { Serial.begin(115200); Serial1.begin(115200); Serial.println("Starting..."); } void loop() { Serial1.write('A'); if (Serial1.available()) { int inByte = Serial1.read(); Serial.write(inByte); } delay(1000); } So far everything works as expected. Then I tr
  6. Hello! In my own automation system I have to encrypt data transferred between sensor and main controller (data transfers via twisted pair). For this reason, I need a special devices - encryption gateways (one gateaway installs on sensor-side, another on controller-side). These gateways realize following algorithm: Sensor-side: Receive some data from sensor (via discrete input); Encrypt data using AES; Transfer encrypted data to controller-side gateway. Controller-side: Receive encrypted data from sensor-side gateway; Decrypt data; Transfer

  8. Hello, I am having a problem using the the Wire examples in energia, master_writer and slave_receiver. I have not modified the code in the examples and just want it to transfer the information across, so that I can work on from there. The two boards are connected together with sda to sda and scl to scl, it shares a common ground and both boards have a 5V supply to the 5V pins However, every time i connect the boards and check the serial monitor on the slave board, all i see is weird unique characters. When i press reset button on the slave board, it will repeat and print the same
  9. Hi all, I'm currently doing a project consisting of msp 432 launchpad along with cc3100 BOOST. I need help in powering the msp and boosterpack from an external supply.I have a a 5v and 3.3 v regulator with me. Please help.
  10. Hello fellows, I made a code to interact the MSP430, with the LCD, but now I would like to have it interact with the MSP432. And I'm having some problems because I want to use specific pins, can anyone help me change the code? My difficulty is: the MSP430 I use PORT P1 and P2, the problem is in the MSP432 I need PORT P2, P5 and P6 This is my connections LCD->MSP432: EN -> (P2 + BIT3) RS -> (P6 + BIT7) D4 -> (P2 + BIT6) D5 -> (P2 + BIT4) D6 -> (P5 + BIT6) D7 ->(P6 + BIT6) lcd.c lcd.h main.c main.h
  11. Hello, I have recently bought cc3100 booster pack to use with msp432 and energia. I connected the boosterpack with the launchpad as shown in the attached pic below. I tried to run the sketch "SimpleWebServerWiFi" , as shown in the tutorial page of energia. I didn't press any switches on the boosterpack and simply connected it with the main board and powered it on and uploaded the example sketch after changing the ssid and password.But the serial monitor outputs nothing and the "http://192.168.1.64/L " page does not load . Please help.
  12. Hi all, I'm using MSP432 with energia. I'm getting weird symbols in the serial monitor instead of the values sent through the Serial.print() function.I have seen these happening when the baud rate specified in code and serial monitor is not same, but this is happening when they are same.Please see the attached image and provide help.
  13. Has anyone uncovered any news about upcoming MSP432 devices? I have some upcoming projects that don't quite fit the current offering. If they had something with USB or Ethernet onboard, it would be a good fit. Competitors already have such ARM devices, but I know the MSP line and could save time if I didn't have to start over with another device.
  14. Hi, I am trying to read ADC channel values from MCP3911 using MSP launchpad using SPI protocol. When i used Arduino Mega the protocol is working fine. But when i use any TI devices i am having a problem, it always gives me all 0'S or 1's. I am using energia for MSP devices. Any i have chosen the appropriate pins as defined in the enegia pin layout. msp430----- static const uint8_t SS = 8; /* P2.7 */ static const uint8_t SCK = 7; /* P3.2 */ static const uint8_t MOSI = 15; /* P3.0 */ static const uint8_t MISO = 14; /* P3.1 */ Can someone help me troubleshoot where i am goin
  15. There is an edX course coming up in September from the University of Texas in Austin - this time with MSP432 or TM4C123 LaunchPad. The parts list also includes the CC2650 and Educational BoosterPack MK-II. The syllabus includes BLE and RTOS. It is taught by Jonathan Valvano and Ramesh Yerraballi who have offered a course using the TM4C123 on edX in the past. https://www.edx.org/course/real-time-bluetooth-networks-shape-world-utaustinx-ut-rtbn-12-01x http://edx-org-utaustinx.s3.amazonaws.com/UT601x/RTOS.html edit: forgot to mention that these courses are free if you just audit th
  16. Hi I am trying to do a MC to MC communication using modbus. I assigned static IP's to both my MC's. WiFiServer MbServer(MB_PORT); WiFiClient client = MbServer.available(); if(client.available()) { ///Do something////// } My question here is, Is there are way I can check the senders IP address before reading modbus packed data in the loop. Because the receiver MC can be jammed with high data throughput as its a open connection (i.e anyone can send data to the MC by knowing its IP address). I want to read the senders IP before doing any data processing. I know using UDP
  17. Hi, I am trying to make a UART connection with a device from serial1 in MSP432. It isn't working as i cannot see anything printing on my serial monitor (I am trying to print the data stored in global variables using serial/USB). Wherein the same code works fine on MSP430 or TM4C1294 devices. I have double checked my wiring connections.. P3.2, P3.3 for RX, TX. Can anyone here help me resolve this issue or point out where im going wrong.. Please find the code below //----------------------------------------------------------------------------- // Microchip MCP39F501 Power Monitor
  18. My latest demo robot for a Automation club I belong too, thought people here might get some use out of it too - since I used a Launchpad MSP432 board :-) http://www.instructables.com/id/Obstacle-Avoidance-Robot-Using-TI-Launchpad-MSP432/
  19. Hi, I am using MSP432P401R to make a UART connection and talk to a board. I have found in the datasheet that MSP432 supports only one UART (RX-P3.2, TX-P3.3). In this case when I use serial to transmit and receive from the other board, Can there be a way i can view the data on serial monitor? How to realize this? I have read in other posts about software serial where GPIOs can be used as serial pins. Can someone brief it for me. My project basically is to read bytes from MCP39F501 onto MSP432P401R and then transmit that data using MODBUS TCP protocol with CC3100 boaster pack.
  20. Hi, I'm doing my Senior design for undergraduate school which is developing an open source medical device using a microcontroller (Arduino or MSP432) with attached ECG, etc. circuits. Also, I am planning of including a LCD touchscreen that will display the recorded ECG signal. The main goal of this project is developing an open source medical device such that the user can add circuits to the microcontroller following the specification that I will develop. The circuits will be built up on top of each other using assigned pins. So, for this kind of project which microcontroller you think

  25. Hello, I want to make a wireless thermometer using two microcontrollers. How do I write the code in Energia to transmit and receive a variable using a 433 Mhz RF module? Transmitter Setup: I have a TM4C123G connected to a RF transmitter using TX(3) pin 34 on the MCU. The TM4C123G is also connected to a LM34DZ Temp sensor. I need help to modify this working code to send the temperature variable using tx(3) pin 34 /*TM4C123G*/ //initializes/defines the output pin of the LM34 temperature sensor int outputpin= A11; // (pin # 2), use A11 analog input //---------------
