https://devzone.nordicsemi.com/f/nordic-q-a/69863/generating-the-frequency-of-1mhz-on-nrf52832Hello, I want to learn how we generate the frequency on nrf52832. I simply take a Blinky led example and on that blinking the led. i want 1MHZ frequency . so how should i proceed for???en-USTelligent Community 13Mon, 28 Dec 2020 17:59:09 GMThttps://devzone.nordicsemi.com/thread/286765?ContentTypeID=1Mon, 28 Dec 2020 17:59:09 GMT137ad170-7792-4731-bb38-c0d22fbe4515:242c54fb-99b0-47ce-804b-d453e49d7e2cCharlie<p>Hi Sunil,</p> <p>There are at least three ways to satisfy your need. I assume that you need a 1MHZ 50%duty PWM wave.</p> <p>1. GPIO toggle + 0.5us dealy, basically like the blinky led example, but the delay function is not accurate, it is hard to achieve 1MHz accurately.</p> <p>2. GPIOE + PPI + Timer, nrf52DK examples\peripheral\gpiote shows exactly how to do this. Just modify the following lines.</p> <p><pre class="ui-code" data-mode="text">... nrf_drv_timer_extended_compare(&amp;timer, (nrf_timer_cc_channel_t)0, 1, NRF_TIMER_SHORT_COMPARE0_CLEAR_MASK, false); ... nrf_drv_timer_config_t timer_cfg = NRF_DRV_TIMER_DEFAULT_CONFIG; timer_cfg.frequency = NRF_TIMER_FREQ_2MHz; ... </pre></p> <p>3. using PWM peripheral. See the example&nbsp;examples\peripheral\pwm_driver.</p> <p>Best regards,</p> <p>Charlie</p><div style="clear:both;"></div>
