  1. But it still does not answers the question why i see I2C device on every adress when nothing is wired ?
  2. Hi, i am having problem with running I2C on stellaris launchpad. I am using this code but i get message device found from each adress, can someone explain me how it works and how should i connect it ? Thanks. Here is the code : // -------------------------------------- // i2c_scanner // // Version 1 // This program (or code that looks like it) // can be found in many places. // For example on the Arduino.cc forum. // The original author is not know. // Version 2, Juni 2012, Using Arduino 1.0.1 // Adapted to be as simple as possible by Arduino.cc user Krodal // Version 3, Feb 26 2013 // V3 by louarnold // Version 4, March 3, 2013, Using Arduino 1.0.3 // by Arduino.cc user Krodal. // Changes by louarnold removed. // Scanning addresses changed from 0...127 to 1...119, // according to the i2c scanner by Nick Gammon // http://www.gammon.com.au/forum/?id=10896 // Version 5, March 28, 2013 // As version 4, but address scans now to 127. // A sensor seems to use address 120. // // // This sketch tests the standard 7-bit addresses // Devices with higher bit address might not be seen properly. // #include <Wire.h> void setup() { Wire.begin(); Wire.setModule(2); pinMode(5,INPUT_PULLUP); pinMode(6,INPUT_PULLUP); Serial.begin(9600); Serial.println("\nI2C Scanner"); } void loop() { byte error, address; int nDevices; Serial.println("Scanning..."); nDevices = 0; for(address = 1; address < 127; address++ ) { // The i2c_scanner uses the return value of // the Write.endTransmisstion to see if // a device did acknowledge to the address. Wire.beginTransmission(address); error = Wire.endTransmission(); if (error == 0) { Serial.print("I2C device found at address 0x"); if (address<16) Serial.print("0"); Serial.print(address,HEX); Serial.println(" !"); nDevices++; } else if (error==4) { Serial.print("Unknow error at address 0x"); if (address<16) Serial.print("0"); Serial.println(address,HEX); } } if (nDevices == 0) Serial.println("No I2C devices found\n"); else Serial.println("done\n"); delay(5000); // wait 5 seconds for next scan }
  3. Hello, i need help with running GY521 gyro on my Stellaris Launchpad with Energia. I found something about wiring GND -> GND 3,3V -> VCC Analog4 -> SDA Analog5 -> SCL and also read this topic at arduino http://playground.ar...c/Main/MPU-6050 there is a sketch but i dont know how to port it at Energia for stellaris launchpad. So i want to ask if there is anybody, who was playing with gyro and can help me understand the way it works. Thanks
  4. I was just wondering what options I have, I think i will do the same as you because i will also need 11,1V battery for running motors, so using regulator on 5V will be also my choice ... thanks for help
  5. Chypsylon What u use as power ? and how big voltage u let flew throught it ? i want to have as much info as possible also any tips are welcomed Thanks
  6. Hello, i wanted to ask what power options I have to power Stellaris Launchpad. I read on official site that i can use one of the micro USB ports but are there any others ways that i cant power it with baterries and make it more portable ? As i read in this article http://blog.psten.de/post/fuel-for-the-stellaris-rocket So does this mean I can connect 5V supply to VBUS on my board and power it from there without making any damage or having to cut the board as mentioned in article ? Thanks for reply
