How does the peripherals (SPI, ADC, I2C) effects on the current consumption?https://devzone.nordicsemi.com/f/nordic-q-a/84860/how-does-the-peripherals-spi-adc-i2c-effects-on-the-current-consumptionHi, I found the online power profiler for BLE ( Online Power Profiler for Bluetooth LE - opp - Online Power Profiler - Nordic DevZone (nordicsemi.com) ), it helped me to get an overall idea about the average current for the ble application and alsoen-USTelligent Community 13Fri, 18 Mar 2022 09:11:28 GMTRE: How does the peripherals (SPI, ADC, I2C) effects on the current consumption?https://devzone.nordicsemi.com/thread/358797?ContentTypeID=1Fri, 18 Mar 2022 09:11:28 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1e9ec550-9d51-4854-b3aa-cb4cd4733d63Sreejith Sundh<p>Hi,</p> <p>Many thanks for your response.</p><div style="clear:both;"></div>RE: How does the peripherals (SPI, ADC, I2C) effects on the current consumption?https://devzone.nordicsemi.com/thread/356566?ContentTypeID=1Mon, 07 Mar 2022 12:10:07 GMT137ad170-7792-4731-bb38-c0d22fbe4515:50a0a2d0-4fa0-4335-879c-09dde468c5d3Stian R&#248;ed Hafskjold<p>Hi, the overall run current for the different peripherals are similar, so the total energy consumption usually depends most on the length of the peripheral active time. I would say that SPI with a high transmission speed would be the best choice. The peripheral can be turned off completely when there is no data transfer. And since the transmission is completed very fast, the total energy consumption will be very low. Depending on what type of sensor you are using, usually the transaction will take place only when there is data ready on the external sensor using interrupts. So no need for polling.</p> <p>Best regards,<br />Stian</p><div style="clear:both;"></div>
