Add Support for Second UART #68

Closed rei-vilo closed 5 years ago

rei-vilo commented 6 years ago

For example, only one UART eUSCI_A0 UART on LaunchPad pins 3=RX and 4=TX is implemented on the MSP430FR2433.

How to use the second hardware UART eUSCI_A1 UART on LaunchPad pins 14=RX and 15=TX?

Thank you!

For MSP430FR2433 the following definitions need to be added in pins_energia.h:

static const uint8_t AUX_UARTRXD = 14;  /* Receive  Data (RXD) at P2.5 */
static const uint8_t AUX_UARTTXD = 15;  /* Transmit Data (TXD) at P2.6 */
#define AUX_UARTRXD_SET_MODE (PORT_SELECTION0 | INPUT)
#define AUX_UARTTXD_SET_MODE (PORT_SELECTION0 | OUTPUT)
#define AUX_UART_MODULE_OFFSET 0x20
#define SERIAL1_AVAILABLE 1

Apart from clarifying that Serial1 and SPI can not be used at the same time.
