Arduino Mega + WiFly

Wireless & IoT
1

To begin, excuse my dumbness. I am very new at this stuff :stuck_out_tongue:

I am working on a project involving driving an RC car using an iPhone over 802.11. I purchased the Arduino Mega 2560, WiFly shield, and Ardumoto. For now, I am simply looking to get some kind of test signal to the Arduino using my laptop, following this tutorial (http://www.sparkfun.com/tutorials/158).

  1. Since I am using the Mega as opposed to the Duemilanove, is the first section of bold code needed (starting with SPI_Uart_WriteByte(LCR,0x80); // 0x80 to program baudrate)?

  2. The second step involves imputing “$$$” into TeraTerm. However, I was unable to find anywhere to enter text here. What am I doing wrong?

  3. Is there any simple open source code out there to test a connection to the WiFly?

Any help would be greatly appreciated, as I am very new at this, and seem to have hit a wall very early on.

Thanks

I purchased the Arduino Mega 2560, WiFly shield, and Ardumoto.

Note that the WiFly and Ardumoto appear not to be compatible as according to http://shieldlist.org/sparkfun/ardumoto the Ardumoto uses pins 11, 12 & 13 for functionality other than SPI.

For now, I am simply looking to get some kind of test signal to the Arduino using my laptop, following this tutorial (http://www.sparkfun.com/tutorials/158).

I suggest you use the [WiFly Shield code library alpha 2 release instead. It documents how to connect a WiFly shield to an Arduino Mega in the “Arduino Mega support” section of [readme file.

  1. The second step involves imputing “$$$” into TeraTerm. However, I was unable to find anywhere to enter text here. What am I doing wrong?

Since the tutorial was written, line-ending configuration support was added to the Arduino IDE Serial Monitor. I suggest you try that rather than TeraTerm.

  1. Is there any simple open source code out there to test a connection to the WiFly?

Yes, check out the examples and tools supplied with the library.
