nRF24AP2 how to connect MSP430G2553?
(1)Asynchronous mode
(2)Synchronous mode      

I have a MSP430 development board(MCU:MSP430G2553). I want to know nRF24AP2 how to connect the MCU.
(1)Asynchronous mode
UART_RX---->P1.2 (right or wrong?)
UART_TX---->P1.1 (right or wrong?)
RTS----> ?
SLEEP----> ?
SUSPEND----> ?
(2)Synchronous mode
SIN---->P1.1 (right or wrong?)
SOUT---->P1.2 (right or wrong?)
SEN----> ?
MRDY----> ?
SCLK----> ?
SRDY----> ?

Thanks!      

Hi,

The ANT asynchronous serial interface is very similar to a standard UART interface, the TXD output on the AP2 should be connected to a UART receive pin on the MSP430 and the RXD input on the AP2 should be connected to a UART transmit pin on the MSP430. The flow control (RTS), sleep, and suspend pins can be connected to any general purpose digital IO pin.

If you haven't already, I would recommend looking into our ANT+ Embedded Reference Designs, our Getting Started with Embedded Systems thread, and associated documents such as our Interfacing with ANT General Purpose Chipsets and Modules.

Cheers
