  1. UART using MSP430FR2311

    I am using a MSP430FR2311 launch pad and i am trying to send AT commands through RX and TX to SIM800 and Receive Response from the SIM800 module. But am not able to get the response and not able to use SoftwareSerial in Energia for MSP boards. Can Anyone help with this problem ? Thank you in advance. #include <String.h> void setup() { pinMode(RED_LED , OUTPUT); Serial.begin(9600); //Serial.print(F("AT\r")); while(Serial.available()==0); val1 = Serial.readString(); Serial.print(val1); Serial.print("\r"); delay(100); } void loop(){ //do nothing if(Serial.available()) { String val2 = Serial.readString(); line += String(val2); Serial.print(line); if (line.indexOf("OK") >= 0) { digitalWrite(RED_LED,HIGH); } } } Since we cant use both the Debugging UART (Serial Monitor) and Application UART (TX and RX) at the same time , I am checking the received Response for the string "OK" . and if OK is there the RED led goes high.
  2. Hi all, I need to import/upload data to my MSP432P401R to call upon in future programs. Since I want this data to exist and be saved when my MSP432 is offline/powered-off, I decided that saving it to flash is the way to go. However, I don't know how to do this. Can anyone offer guidance or suggestions? Or does anyone have a better way of doing this? I'm using Energia v18.
  3. Neural network code

    Hello there, I am new to this forum. I wanted a code which could help me create a neural network to correlate my sensor data and get the desired output. I am using MSP430G2553 micro-controller with Energia as the software. It will be a great help. Thanks in advance.
  4. Hello everyone, I have a problem with Energia and my MSP430F5529, this micro is enable to use 12bits ADC, but I can't find the way to make it enable that configuration because Energia runs my code in default 10bits ADC, some one can tell me how can I configure the ADC to use 12 bits resolution??, this is my code: #include <Servo.h> Servo servo; int potpin = 23; int volt, i; void setup() { servo.attach(19); } void loop() { volt=analogRead(potpin); i=volt/6; //I'ms using 6, because 1023/6 = aprox ? 180 steps that I need. I want to use 4095/23 ? 180 steps servo.write(i); delay(100); } My code is working, but is working with 10bits resolution, and I need 12bits.Thanks for attention to my post ^^
  5. Hi everybody fooling around with the MSP432 launchpad. Does anybody know how to properly and elegantly use bit banding? Could not find much on the web and in the examples... This does not work, does not even create an error message: // this does what you expect, a short pulse P1OUT |= BIT0; P1OUT &= ~BIT0; // this does nothing BITBAND_PERI(P1OUT,BIT0)=1; BITBAND_PERI(P1OUT,BIT0)=0; does anybody know what I am doing wrong here?
  6. Strategic advice for MSP presentation

    Hi everyone, I wanted some strategic advice from the Forum on an MSP event I'm organizing in Rome next week (everyone is invited, the link is at the end of the post). I'm trying to introduce the MSP hardware/software platform to an arduinocentric audience who is unaware of other - better in my opinion - options such as ours. For the hands-on part, I'm basically going to open up a sketch in Energia - which they will recognize as an "Arduino in red" - and then I want to migrate it into Code Composer Studio, in order to show them what a professional IDE is all about and what it offers. My idea is to focus on two - of the many - reasons to make the move: debugging and low-power-oriented coding. I have very little time and the group is diverse in that it will include complete newbies all the way to engineers. I'm a bit stuck with my C mindset to come up with a proper minimal Energia sketch that is meaningful to view in the debugger and possibly in the disassembly view too. The other issue I've encountered is that, once imported and run in CCS, the sketch forks in a maze of Wiring self-generated derivatives and routines that are hard to follow for a beginner. Showing them the low power modes in the register view is also a possibility, but it's perhaps a bit too advanced as it requires mentioning interrupts and ISRs. Bottom line, it has to be as simple as it gets because my goal is to get the audience interested, not to teach them. My initial idea was to show a modified Blink sketch with a couple of incrementing globals that can be tracked down in the debug view, both as expressions and in memory, but honestly it doesn't mean much to me. I would really appreciate any feedback or input from the brilliant 43oh collective mind on more creative - and yet simple - ways to get the message through... Link to free event (breakfast with organic pastries is offered) if you want to attend! http://ow.ly/LK01A Thanks Stefano
