Hi im new on energia and im trying to recieve data from bluetooth by a HC-06 module conected to my launchpad (HardwareSerial) but i dont recieve anything, this is my code and neither green led or red led are turning on when i send data to it by my laptop or my smartphone. hope somebody can help me thanks char incoming; void setup() { // Open serial communications Serial.begin(9600); pinMode(RED_LED,OUTPUT); digitalWrite(RED_LED,LOW); pinMode(GREEN_LED,OUTPUT); digitalWrite(GREEN_LED,LOW); } void loop() // run over and over { if (Serial.available()){ digital

thank you !! I'm working and understanding a lot more

hey thanks for the link.... I don't understand assembler I'm a beginner sorry... could some body traduce it to energia language ? please thanks

hey I'm a beginner on energia and I want to get the frequency of a signal but I don't know how to use interrupts and timers with launchpad or... other way to get it thanks

nop still not working

THANK YOU I UNDERSTAND NOW im going to fix it

yes it works, and matlab works with float too so it works fine and relatively faster because i use only 8 points but... i dont understand how to know the frecuencies of each point... or the range... thanks for the response

hey I finally found a Code to work with FFT on Energia, it is very simple, so I can understand it but, there is a thing that i Cant understand, and it is the frecuency because i get the amplitude but I dont know what the frecuency for every amplitude is... this is the code: #include <math.h> #define ANALOG_IN 0 void setup() { Serial.begin(9600); } void loop() { fourier(); } void fourier(){ int var = 0; while(var < 1){ /////------------------------------------------------------------------------g

thanks for the response.. but i think its going to be hard for me to export the library to energia since im a beginer... would you help me ? or.. any body has another choise to work with FFT? Thanks

I tried this, and when i conect the LP everything ok, run energia (keep the button pressed) it starts well and I can see the serial port enable and I can open the serial monitor but when i realese the button the serial port option gets disable and serial monitor doesnt works either... thanks for the reply

Hello to all! Im new using Launchpad and energia, and im trying to make a Spectrum analyzer, so to make it works i need to use the fast fourier transform, to change from time domine to frecuency domine, ok so.... I was looking for a library with the FFT but only found one for arduino... it is the FIX_FFT.H here: http://arduino.cc/forum/index.php/topic,38153.0.html but... this library uses another library the avr/pgmspace.h so I can not use this... anybody knows a FFT library for energia? or how to make it works without avr/pgmspace.h or with a replace.... or some code to

ok I added the rule to udev but still doesnt working... something weird is that when i use the jumpers rotated and run energia, when i select TOOLS from the menu it crash a bit and then it shows the TOOLS menu but serial port is disable... I dont know what is happening... Thanks for the replies

ok so this is what i got when i try this, and no i dont have a modem manager installed Jan 26 20:46:32 AOA150 kernel: [22173.352171] usb 2-1: USB disconnect, device number 2 Jan 26 20:46:44 AOA150 kernel: [22185.304124] usb 2-1: new full-speed USB device number 3 using uhci_hcd Jan 26 20:46:44 AOA150 kernel: [22185.518482] cdc_acm 2-1:1.0: This device cannot do calls on its own.

Thanks I'm going to try it
