5.2 WiFi
A very popular WiFi module (1) labeled as CC3100 allows WiFi connectivity.
This module is the complete WiFi solution on a chip: it is a powerful WiFi
network processor with the power management subsystem, offering the
TCP/IP stack, powerful crypto engine with 256-bit AES support, WPA2
security, SmartConfig
™
technology, and much more.
By offloading the WiFi and Internet handling tasks from the MCU, it allows
the host MCU to process more demanding graphical applications, thus
making it an ideal solution for adding WiFi connectivity to mikromedia 7.
It uses the SPI interface to communicate with the host MCU, along with
several additional GPIO pins used for the reset, hibernation, and for the
interrupt reporting.
An SMD jumper labeled as FORCE AP (2) is used to force the CC3100
module into an Access Point (AP) mode, or into a Station mode. However,
the operating mode of the CC3100 module can be overridden by the
software. This SMD jumper offers two choices:
0: the FORCE AP pin is pulled to a LOW logic level, forcing the CC3100
module into the STATION mode
1: the FORCE AP pin is pulled to a HIGH logic level, forcing the CC3100
module into the AP mode
There is a chip antenna (3) integrated on the PCB of the mikromedia 7, so
no additional hardware is required in order to establish the connection over
the WiFi network.
