Re: Using SPI mode to interface msp430 with RFtransciever&am
It is better to configure the STE line as GPIO and then use as CS. Because some of the SPI devices need CS to be active between consecutive transfers. If you use STE it will go into inactive state between continous transfers.

hi
I am also currently working on the same micro.
I cant see interrupt handler in your code.
When the timer generates and interrupt your micro needs to store all the current registers and PC into interrupt stack and then service the ISR. At the end of the ISR you need to...
