Other Parts Discussed in Thread: CC2640

Hi all,

I can map 32768Hz LF Clk to CC2640 IO as below link. Now need to output a high frequency clk, around 3MHz, as a clock source. would you please kindly suggest how to generate and output 1M~10MHz Clock, is it possible to map HF clock to IO? Thanks a lot.

Hi Lina,

You can do this with a PWM output. We will have an official driver in the TI RTOS december release. Until then you can use the example in the below link with PWM_DIV_FACTOR = 16 for 3 MHz.

Svend,
Thanks a lot for your kindly help. :) Will new TI RTOS can be used for BLE stack2.1 or release a new Rev. stack? Thanks.

BR,
Lina
