WIZnet / Mbed 2 deprecated SerialPassthrough_GainspanModule_W7500

Gainspan module evaluation with WIZwiki-W7500 using SerialPassthrough.

Dependencies:   mbed

Fork of SerialPassthrough_GainspanModule_W7500 by Steve Kim

This is a serial-passthrough example using WIZwiki-W7500 and gainspan-WiFi-module.

With this example, I can issue at-command-sets to the WiFi module with WIZwiki-W7500's serial. UART data flow is shown as below.

[PC Serial Terminal] <=> [WIZwiki-W7500's UIART1/DAP] <=> [WIZwiki-W7500's UIART0] <=> [Gainspan WiFi module]

Connected pins between WIZwiki-W7500 and WiFi-module are only 4 pins. (3.3V, GND, UART-Tx, UART-Rx) And, here is a picture. /media/uploads/SteveKim/gainspan-w7500.jpg

And here is a captures of test logs. Red box is what I issued.

[PS] ASYNC_DEBUG is for internal-debugging like ISR. You can ignore it.
