  1. Hello, I am working on a project where I am trying to acquire ECG data for further analysis. Using AD8232 sensor I was able to get my raw data. So far I am using MSP430F5438A and my compiler is Code Composer Studio (CCS). I was asking if anyone did the next processing like filtering to remove noise and interference, at msp430. Can you please share your work (Analysis algorithm and Code)? Here in the attachment the graph of the raw data I am getting from my sensor (ADC values actually). Following is the link to AD8232 sensor datasheet: http://www.analog.com/media/en/technical-docu
  2. Hello, I'm trying to write to a file and then reading back from it. I'm using code composer studio. After execution, I can see a file is created but nothing is written in it (Didn't get any error). Below is the code. What is the possible issue here? I omit the reading part as I couldn't able to write. #include <msp430.h> #include <stdio.h> void main() { WDTCTL = WDTPW + WDTHOLD; // Stop WDT FILE *fread; fread= fopen("testing", "w"); // not sure if I should add the file extention here like testing.txt but I tried including
  3. Hello, I am trying to record my voice using MSP430F5438A onboard microphone. So as a starting point I am reading the microphone data(Channel 5, ADC12). I am sending the data directly to PC and observing the output at tera term. But I am confused seeing the ADC output. After a certain amount of data, the value saturates and actually doesn't change at all even if I speak or make a sound. I don't catch where I'm doing wrong. I'm attaching my code and the data output snapshot. Any suggestion is highly appreciated. #include <msp430.h> unsigned int voice; volatile unsigned char vo
  4. Hello, I am trying to collect data from the following optical dust sensor: https://www.sparkfun.com/datasheets/Sensors/gp2y1010au_e.pdf According to page 5 of the datasheet, I generated the correct PWM signal using timer A for input PIN 3 of the sensor and observed the signal in my oscilloscope. Now at the same page Figure 2, they talked about the output pulse sample timing. Anyone can help me understand how should I set up my ADC12 for this? Few queries regarding this: 1. Should my sample and hold time be 0.28ms? 2. If so then should I wait for next 0.04ms + 9.68ms t
  5. Hello, I am planning to analyze breathing pattern using a microphone. I have MSP430F5438A Experimental board. I found that the board itself has a microphone. I am looking for any documentation available about how to use the microphone from the board. I did a little bit of research but didn't find details other than the user guide for the board. I appreciate any recommendation. Thanks, Row
  6. Hello, I am trying to get RED, IR and GREEN led value in real time from MAX30101 sensor. I am using MSP430F5438A as my MCU. My IDE is CCS. The protocol required to communicate with the sensor is I2C. Now my problem is I am not any value except 0 in my read and write pointer (Indicated in the comment in my code). I am supposed to get some value in between 0 to 32. I'm attaching the link for the datasheet for the sensor: https://datasheets.maximintegrated.com/en/ds/MAX30101.pdf I know the datasheet is a whole lot. But I am referring page 17 which they have a pseudo code how to burs
  7. Trying to work with SPPDemo (MSP430F5438A+ CC2564B) according to the steps described at the link below: http://processors.wiki.ti.com/index.php/CC256x_TI_Bluetooth_Stack_SPPDemo_App I was able to open the server. But on the client side, I can't see the device list with DisplayInquiryList Command. I tried Inquiry command before it to initialize the process. Both the pictures of server and client are added.
  8. Hello, I am looking for a Bluetooth module which I can work with MSP430F5438A (Microcontroller). I am using Code Composer Studio (CCS) IDE. I searched Google a bit and also went through TI web pages about the possible module. I was wondering if anybody can suggest any module which I can work with that specific micro-controller? Other issue is please suggest a module which has enough documents and demo project (Possibly in CCS) to get started and go further. Thanks, Rowshon.
  9. Hello, Can anyone help me with the source code for the pulse oximeter of the MAX30100 sensor (I2C communication)? Following is the datasheet: https://datasheets.maximintegrated.com/en/ds/MAX30100.pdf I'm using MSP430F5438A. Thanks.
  10. I am trying a loopback test for msp430f5438a using interrupts. I have initialized the master and slave modules and have written their respective functions as interrupt service routines. The aim I to turn the LED off when the slave receives a character.However, the code is not working. Please tell me how to make it work --------------------------------------------------------------------------------------------------------------------------------- // To use interrupts to transmit and recieve text character(s) #include <msp430.h> /* * main.c */ ? ? void main(void) { WDTCTL = WD
  11. Hello, I am working on project to design sensor network. I want to send my data over internet. I read the TI manual (slaa 137a) regarding internet connectivity of MSP430. They have shown interfacing between MSP430F149 and CS8900A ethernet controller. I am working on MSP430F5438A. I want to know is it possible to interface MSP430F5438A with CS8900A as shown in manual. If it is possible then should I interface CS8900A with any general purpose port of MSP430F5438. Shall I need RTOS for MSP430F5438 to implement ethernet connectivity?
  12. Hi, I'm new to embedded programming, and I have to interface an MSP430F5438A with an Emmoco EDB-BLE Bluetooth Low Energy board, in order to send data to iOS devices. I am not sure how to proceed with this, as Emmoco directs you to write a driver for your particular board (http://dev2.emmoco.com:8090/display/em/Embedded+Platform+Support) and uses Eclipse to build their software (http://dev2.emmoco.com:8090/display/em/Install+Em-Builder). I believe I have correct code, but it seems Eclipse will not recognize my MSP-FET430UIF programmer and so the code never loads into the board. I get a "gma
