CC3200/3100MOD Breakout Board

Energia supported CC3200 launchpad, and the upload method is using onboard FTDI chip

to do the reset, since I hate FTDI, I'm not going to use the same chip on my PCB.

but that makes this breakout can't auto reset.

So the upload process become an old Arduino, after uploading then press reset, and it will upload program to CC3200, but the debug stage will fail, I'm finding a way that when CC3200prog.exe send a break signal, CC3200 will auto reset, hope I can do it with passive components rather then some atmega16U2 as UART to USB.

So by using Uniflash to flash and energia to compile, I can now using CC3200.

but the PCB have to do some modification

first, adding a switch and two 2.7K resister to choose between UART Upload and Normal mode.

second, adding a tact switch for reset function.

the whole process is:

1. Switch to UART Upload mode

2. select the bin file

3. click program, and when it tells to reset, press the reset for about 3 sec

4. finish

here is the example of AP mode.

and Serial echo example in the SDK.
