dflet 0:305844973572 14 * ( Yes I know they are for an Arduino, but some still do apply.)
dflet 0:305844973572 15 * Most important!
dflet 0:305844973572 16 * The mbed will not supply the current that the CC3000 requires, if you try it will

dflet 0:305844973572 30 To connect an mbed to the CC3000 you'll need to make these 6 connections

dflet 0:305844973572 37 exchange data with the CC3000. This is
dflet 0:305844973572 38 mbed pin 8, but any pin can be used. In this
dflet 0:305844973572 39 program it will be called cs.

dflet 0:305844973572 123
dflet 0:305844973572 124
dflet 0:305844973572 125 WARNING #1: The CC3000 runs at 3.6V maximum so you can't run it from your
dflet 0:305844973572 126 regular 5V Arduino power pin. Run it from 3.3V!
dflet 0:305844973572 127
dflet 0:305844973572 128
dflet 0:305844973572 129 WARNING #2: When transmitting the CC3000 will use up to 275mA current. Most
dflet 0:305844973572 130 Arduinos' 3.3V pins can only supply up to 50mA current, so you'll need a
dflet 0:305844973572 131 separate power supply for it (or a voltage regulator like the LD1117V33
dflet 0:305844973572 132 connected to your Arduino's 5V power pin).
dflet 0:305844973572 133
dflet 0:305844973572 134
dflet 0:305844973572 135 WARNING #3: The CC3000's IO pins are not 5V tolerant. If you're using a 5V
dflet 0:305844973572 136 Arduino you will need a level shifter to convert these signals to 3.3V
dflet 0:305844973572 137 so you don't blow up the module.
dflet 0:305844973572 138
dflet 0:305844973572 139 You'll need to shift the pins for WLAN_CS, MOSI, SCK, and WLAN_EN. The other
dflet 0:305844973572 140 2 pins (WLAN_IRQ and MISO) can be connected directly because they're input
dflet 0:305844973572 141 pins for the Arduino, and the Arduino can read 3.3V signals directly.
dflet 0:305844973572 142
dflet 0:305844973572 143 You can use a level shifter chip like the 74LVC245 or TXB0104 or you can use
dflet 0:305844973572 144 a pair of resistors to make a voltage divider like this:
dflet 0:305844973572 145
dflet 0:305844973572 146 Arduino pin -----> 560 Ohm -----> 1K Ohm -----> GND

dflet 0:305844973572 529 results - 4 bytes - 0=aged results, 1=results valid, 2=no results. Why TI
dflet 0:305844973572 530 used 32 bits to store something that could be done in 2,
dflet 0:305844973572 531 and how this field is different than isValid below, is
dflet 0:305844973572 532 a mystery to me so I just igore this field completely.
dflet 0:305844973572 533
dflet 0:305844973572 534 isValid & rssi - 1 byte - a packed structure. The top bit (isValid)
dflet 0:305844973572 535 indicates whether or not this structure has valid data,
dflet 0:305844973572 536 the bottom 7 bits (rssi) are the signal strength of this AP.
dflet 0:305844973572 537
dflet 0:305844973572 538 securityMode & ssidLength - 1 byte - another packed structure. The top 2
dflet 0:305844973572 539 bits (securityMode) show how the AP is configured:
dflet 0:305844973572 540 0 - open / no security
dflet 0:305844973572 541 1 - WEP
dflet 0:305844973572 542 2 - WPA
dflet 0:305844973572 543 3 - WPA2
dflet 0:305844973572 544 ssidLength is the lower 6 bytes and shows how many characters
dflet 0:305844973572 545 (up to 32) of the ssid_name field are valid
dflet 0:305844973572 546
dflet 0:305844973572 547 frameTime - 2 bytes - how long, in seconds, since the CC3000 saw this AP
dflet 0:305844973572 548 beacon
dflet 0:305844973572 549
dflet 0:305844973572 550 ssid_name - 32 bytes - The ssid name for this AP. Note that this isn't a
dflet 0:305844973572 551 regular null-terminated C string so you can't use it
dflet 0:305844973572 552 directly with a strcpy() or printf() etc. and you'll
dflet 0:305844973572 553 need a 33-byte string to store it (32 valid characters +
dflet 0:305844973572 554 null terminator)
dflet 0:305844973572 555
dflet 0:305844973572 556 bssid - 6 bytes - the MAC address of this AP
