low CC2430 Timer1 resolution

Hi,

I am developing a prototype using the CC2430 evaluation boards. I need to test the lowest time period that i can count using a timer. I set the CC2430 system clock to 32MHz, timer tick period = 32MHZ and am running Timer1 at 32MHz (prescaler = 0). The Lowest interval period i could acieve was about 1600ns.

I expected to get a much better resolution since TI specifies that most instructions are 1 cycle, and also the minimum interrupt delay is 7cycles. Since i have not enabled any other interrupts except timer1 Channel, i dont see why i shud compromise with 1.6us.

Thanks in advance for your time advice.

Cheers,
Lewis

Plz: I am using IAR embedded workbench

Hi,

Thanks for replying.

I am trying to implement a simple solution for counter with a resolution of 1us or better without the complexity of managing my software counter in addition to timer ticks.

Thanks in advance for your time and advice
