CC3200: Connect three devices simultaneously

Hi,

Because CC3200 have only two UARTs you can communicate at on moment only with two devices. You will need multiplex one of the UARTs (UART will be shared). For this purpose you can use external MUX chip or use internal pinmux (see API PinTypeUART()).

Let say you want use UART0 with pins 55, 57 and 4, 3:

// use pins 4, 3 for RX, TX UART0
PinTypeUART(PIN_03, PIN_MODE_7);
PinTypeUART(PIN_04, PIN_MODE_7);

// use pins  57, 55 for RX, TX UART0
PinTypeUART(PIN_55, PIN_MODE_3);
PinTypeUART(PIN_57, PIN_MODE_3);
