1  Using Arduino / Programming Questions / Re: Can Arduino Playground code for an Arduino Uno be used for SainSmart Uno on: April 16, 2014, 08:57:36 am
There are no operational differences between a SainSmart Uno and a Arduino branded UNO.  Any 328 based Arduino clone will work the same. And Paul, this forum isn't just for Arduino Hardware, it's for Arduino software issues as well, so stop being a bigot :-)

Here is another example of viewing NEMA data in the serial monitor. LCD display is coming soon.

Here is my Neo-6m solution, should work fine for you:

How is your project going? Have you seen http://digitalcommons.calpoly.edu/cgi/viewcontent.cgi?article=1129&context=eesp ?

Still hoping Nick jumps in with some guidance.
10  Using Arduino / Displays / Nick Gammon VGA on: November 29, 2013, 09:38:34 am
I built a VGA co-processor per Nick's instructions at http://www.gammon.com.au/forum/?id=11608

I'm using the 8 color version and am successfully running the color test on my VGA enabled TV. I'm ready to move on to the host arduino sending commands over I2C, but I'm having difficulty reconciling the B/W sketch with communications with the 8 color sketch without communications. Nick, please help? Do you have the comms enabled sending sketch that works with a comms enabled 8 color receiving sketch handy?

11  Using Arduino / Networking, Protocols, and Devices / Re: Microcontroller-based switching of AT mode for HC-05 Bluetooth module? on: November 18, 2013, 05:44:48 pm
The HC-06 just needs a nice little sketch to go into AT mode (see below). The HC-05 requires pin 34 to be held high, and the power cycled (see http://www.instructables.com/id/Modify-The-HC-05-Bluetooth-Module-Defaults-Using-A/ )

Code:
// http://www.instructables.com/id/Success-Using-the-JY-MCU-linvor-Bluetooth-Module/

#include <SoftwareSerial.h>

SoftwareSerial mySerial(10, 11); // RX, TX
String command = ""; // Stores response of bluetooth device
                                     // which simply allows \n between each
                                     // response.
void setup()
{
   // Open serial communications and wait for port to open:
   Serial.begin(9600);
   Serial.println("Type AT commands!");
   // SoftwareSerial "com port" data rate. JY-MCU v1.03 defaults to 9600.
   mySerial.begin(9600);
}

void loop()
{
   // Read device output if available.
   if (mySerial.available()) {
     while(mySerial.available()) { // While there is more to be read, keep reading.
       command += (char)mySerial.read();
     }
     Serial.println(command);
     command = ""; // No repeats
   }
 
   // Read user input if available.
   if (Serial.available()){
       delay(10); // The DELAY!
       mySerial.write(Serial.read());
   }
}// END loop()
12  Using Arduino / Networking, Protocols, and Devices / OBD-II not working on: November 18, 2013, 09:24:32 am
I have the OBD-II Version 1.2 from http://www.arduinodev.com with the white data logging shield. I connected a HC-05 Blue tooth module to my arduino, and verified I can display data on my phone from the arduino. Then I attached the OBD-II shield, and connected the cables, green/white to IIC1, and the black/red/blue/yellow to the connector next to it. With the following code, I get no display on my phone. Thoughts?

Code:
#include <Arduino.h>
#include <Wire.h>
#include <OBD.h>

// OBD-II I2C Adapter
COBDI2C obd;
 
#include <SoftwareSerial.h>

SoftwareSerial mySerial(10, 11); // RX, TX

 
void setup()
{

  
    // set the data rate for the SoftwareSerial port
  mySerial.begin(9600);
  
 
  // start communication with OBD-II UART adapter
  obd.begin();
  // initiate OBD-II connection until success
  while (!obd.init());  

}
  
void loop()
{
  
    int rpm;
    int mph;
 obd.readSensor(PID_RPM, rpm);
 obd.readSensor(PID_SPEED, mph);
    


 mySerial.print(mph);
 mySerial.print(" ");
 mySerial.println("MPH");  
 mySerial.println(rpm);
 mySerial.print(" ");
 mySerial.println("RPM");
 
}

Here is a working example of the HC-05 using terraterm. I'm also displaying the data on my android phone using bluetooth terminal.

You can change the softserial ports to any available digital pins.
14  Using Arduino / Project Guidance / Re: Trouble shooting a bread-board Arduino on: November 10, 2013, 09:27:09 am
not only that, but the board type you use is dependent on which bootloader is installed. Some of my atmel 328's came with uno bootloaders, others with duemilanove. Many of the ftdi adpters have tx/rx reversed (have not used adafruit), so it's tx - tx and rx - rx. some use a .1uf on the rts, instead of the dtr. http://www.instructables.com/id/The-Embedded-Arduino-building-an-Arduino-into-a-p/
15  Using Arduino / Programming Questions / Re: disassembling incoming serial data on: October 08, 2013, 06:35:42 am
I'm receiving the data and assembling it into a variable, and able to print that variable. Now I just need to parse the data into the individual variables and data. I'll post the code later. Lightning took out my phone and internet Sunday, and it should be back up later today.
