However, the 10 pin header has UART0 and I2C connections. Unfortunately all of these pins share USART0 so you will run into the same abritration problem described below. you should also get a copy of the TI data sheet for the msp430f1611 (the processor on the telosb) as well as the user's guide. In other words do your homework. UART0 and the Radio (SPI mode on USART0) both share the USART0 hardware. That is why they need to arbitrate for the h/w. This makes doing anything reasonable as far as receiving information via the UART very problematic if one is using the Radio too. It is one of the reasons we abondoned the telosb/1611 and went to the 5438a processor. > > Can you please guide me for this case? What interfaces can be used in > this case?
