  1. CC3200 LAUNCHXL v4.1 ENERGIA 0101E0013 WINDOWS 7 Hi Guys, So I just got a few CC3200 Launchpads to do some prototyping on. Ultimately I would like to be able to connect onto the Launchpad without having to first go through my router. But I digress... I've been running the SImpleWebServerWIFI sketch from Energia. It works as expected when I have my computer with Chrome accessing it, But as soon as I connect with my Android phone(4.4.2) and chrome(v39.0.2171.59) and press a button the unit freezes up. Attempting to connect to Network named: WNL108 .. You're connected to the network Waiting for an ip address . IP Address obtained SSID: WNL108 IP Address: 192.168.1.11 signal strength (RSSI):0 dBm To see this page in action, open a browser to http://192.168.1.11 Starting webserver on port 80 Webserver started! new client GET / HTTP/1.1 Host: 192.168.1.11 Connection: keep-alive Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8 User-Agent: Mozilla/5.0 (Linux; Android 4.4.2; D6503 Build/17.1.2.A.0.314) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/39.0.2171.59 Mobile Safari/537.3 As I initially said I would like to be able to connect directly to my CC3200 device. Any help would be greatly appreciated
  2. Hi All, I'm excited to meet more of the makers in this forum. I've been playing with TI Launchpads for a couple of years now. Since my background is in wireless and AI, I've been connecting bluetooth and wi-fi radios to these things with some Android/iPhone applications. I've developed an open source virtual machine that enables programming via a simple pin oriented interpreted language(similar to wiring) from your smartphone and have started rolling out some application specific kits around this. You can checkout my projects on my blog. I'm joining this forum because I've been thinking about a new bluetooth motor control boosterpack and wanted to see what the interest level on this might be. BR, Leo
  3. Hi guys, I'm working in a project and I want to know how can i make an android application connect with JY-MCU (Bluetooth Module) and MSP430G2553. Could anybody send me an tutorial or something? Best regards, John
  4. I had been working on a compact health monitoring system which would have ECG, body temperature sensor, glucometer, and a pulse oximeter all put on one single PCB. So far I was successfully able to have ECG, temperature and the glucometer working. Having this was not sufficient, I wanted to send all this data onto an android phone. For this I used HC-06 bluetooth module and had an android app running on the phone to collect and display the data on to its screen. I made use of Amarino's library for communication between Arduino and Android. It was pretty easy to port Amarino from Android to Stellaris and it worked very well! I used Stellaris Launchpad in my project considering that I would be implementing signal processing in future and also it is quite inexpensive This is my entire unit fit in one box. I plan to having the processor on the same board and eliminating the use of bulky launchpad. Can anyone tell me how I could do that? I have never done such a thing before. Just showing off some photographs The step up converter that I used to power up all the circuits in that box. Takes 3.5 to 4V from Li-ion battery (NOKIA) and converts it to 5.1V. Pretty cheap module I found on some chinese website. This is my android app showing my ECG. I can enter my name in the text box and upload the ECG onto the online website. Note: I used Amarino's example SensorGraph and modified it to add the uploading functionality. You can view the database here : http://projectarogya.com/arogya/patients.php This is how my ECG looks online. The php script also does the task of calculating heart rate and putting a time stamp at the time of upload. I am using a simple LM35 temperature sensor. I had to build seperate app for temparature and glucometer. Note: I used Multicolorlamp app from Amarino's website and modified it. Now it is so much modified that its like a completely new app except that the name is still unchanged I have also uploaded a more detailed blog post on http://nuclearrambo.com/wordpress/android-based-wireless-ecg-monitoring-temperature-sensor-glucometer-included/ Because of some problem with ground, I am not able to get a clean output. It fluctuates a lot and hence does not give correct glucose readings. I will add in the explanation about how glucometer works if you people want to hear about it. PS: I had only been reading on this forum. This is my first post here and I thought I would share my project with you all. I am also hoping to produce and sell it once its complete. If anyone's interested in lending a helping hand with design and stuff are totally welcome

    guys how do i choose which platform to work on? Ångström Linux Android Ubuntu Cloud9 IDE I knw C/C++, JAVA lang....but i m ready to learn another if needed I want to build real time OCR project using BBB as processing device.....
  6. I was wondering, does anybody know of a good msp430 compiler like IAR for mobile devices? If not, I have some ideas if anybody is up for making one. Physically connecting to the phone is out of the question, so it would have to be bluetooth. An msp (preprogrammed) with a bluetooth transceiver may just be all that's needed to program another msp via spi-bi-wire, and possibly throw in an rx/tx port to transfer data back through the Bluetooth, just like the launchpad does with USB. Just tossing ideas out.
  7. Hi everyone, I wanted to connect a MSP430 to an Android device. In fact, my idea was to use the MSP430 launchpad as a low-cost GPIO board for an Android tablet. I did a little research, and first thought on the audio port for the communication ( http://robots-everywhere.com/re_wiki/index.php?title=Serial_on_Android_using_the_audio_port ) but then I remembered that the tablet supported USB OTG. So, I compiled the CDC_ACM module for the (Allwinner A10 based) tablet in order to emulate serial port over USB. Then, in the MSP430 Launchpad side, I needed a lib for using the serial port. I found MSP430-softuart by Stefan Wendler (https://github.com/wendlers/msp430-softuart) and used it for the bidirectional communication Android-Tablet<->MSP430-Launchpad. In order to make a demo, I modified the code of Open Source Vector Pinball (http://dozingcatsoftware.com/VectorPinball/index.html ), adding support for serial port access (using http://code.google.com/p/android-serialport-api/). This modified Vector Pinball has the flippers linked to MSP430 Launchpad buttons. When the buttons on P2.5 and P2.3 are pressed they flippers are activated. A LED is also connected on P1.6 in order to toggle it when receiving "toggle" command from the Android app. You can find the video demo here: This is the source code for the MSP430 (find it also attached to this post) #include <msp430.h> #include <stdint.h> #include "uart.h" #define LED1 BIT0 #define LED2 BIT6 #define BUTTON1 BIT5 #define BUTTON2 BIT3 static volatile bool r = false; static volatile bool l = false; int main(void) { WDTCTL = WDTPW + WDTHOLD; // Stop watchdog timer BCSCTL1 = CALBC1_1MHZ; // Initialize clock DCOCTL = CALDCO_1MHZ; P1DIR |= (LED1 + LED2); // Set BIT0 and BIT6 as output P1OUT &= ~(LED1 + LED2); // LEDs off P2REN |= (BUTTON1 + BUTTON2); // Select pull-up resitors por P2.3 and P2.5 P2IE |= (BUTTON1 + BUTTON2); // Enabling Button interrupts P2IFG &= ~(BUTTON1 + BUTTON2); // Clear interrupt flags for the buttons uart_init(); __enable_interrupt(); uint8_t c; while(1) { if(uart_getc(&c)) { if (c == 't') { P1OUT ^= (LED2); // Toggle LED2 } } if (l) { uart_putc('l'); // Send "left" command via UART l = false; } if (r) { uart_putc('r'); // Send "right" command via UART r = false; } } } // Port 2 interrupt service #pragma vector=PORT2_VECTOR __interrupt void Port_2(void) { if ((P2IFG & BUTTON2)) { P1OUT ^= LED1; // Toggle LED1 P2IFG &= ~BUTTON2; // Clear BUTTON2 interrupt flag P2IES ^= BUTTON2; // Interrupt called on High-to-Low and Low-to-High l = true; } if ((P2IFG & BUTTON1)) { P1OUT ^= LED1; // Toggle LED1 P2IFG &= ~BUTTON1; // Clear BUTTON1 Interrupt flag P2IES ^= BUTTON1; // Interupt called on High-to-Low and Low-to-High r = true; } } Later today, I will include the schematic and a guide with the steps for replicating the setup in case you want to build it. Do you find the project interesting? msp430-pinball.tar.gz
