running the NRF51822 @ 1MHz

[wogisha]

how can i run the NRF51822 at 1MHz so that I save the power consumption? the data sheet talks of 275 μA/MHz I want to have it consume only 275 μA

You can't. The 275uA/MHz is just a measure of the cortex processor's efficiency in general, not an indication that you can pick the processor clock speed. You can only run it at 16MHz. Of course running it at 16MHz means you only need power it for 1/16th of the time you would at 1MHz and properly written applications will spend most of their time in sleep mode where the processor is consuming almost no power at all.

thank you, its good idea
