Arduino megaAVR ADC Oversampling, e.g. Nano Every ATmega4809

The megaAVR 0-series MCU ADC sample accumulation … ↓↓↓ Complete description, time index and links below ↓↓↓ I’ve already done eight videos about the Arduino Nano Every, its ATmega4809 MCU and the Microchip megaAVR 0-series family of MCUs in general. This time I want to have a look at the accumulation feature of the ADC and oversampling. First we choose a signal source (internal temperature sensor). Then we have a look at the datasheet and implement sampling with 64x accumulation. Finally we go over the principle and math of oversampling and implement that too. 00:00 Intro – megaAVR 0-series ADC accumulation 00:51 Signal – temperature sensor of the ATmega4809 04:00 Datasheet – ADC, CTRLB register, SAMPNUM parameter 07:15 Accumulating – averaging samples to decrease noise 11:07 Oversampling – the principle and the math 16:46 Increasing resolution – with oversampling of course 24:08 Experimenting – just fooling around with the results 28:10 Wrap-up – maybe you can guess what’s next, bye Tutorials    • Tutorials   Arduino Nano Every: The Better Nano? – Tests and Shootout with Nano v3    • Arduino Nano Every: The Better Nano? – Tes...   Arduino Nano Every – Power Supply Architecture and Brownouts    • Arduino Nano Every – Power Supply Architec...   Arduino Nano Every: Four Hardware Serial Ports – Without Additional Hardware    • Arduino Nano Every: Four Hardware Serial P...   Arduino megaAVR Watchdog & Resets, e.g. Nano Every ATmega4809    • Arduino megaAVR Watchdog & Resets, e.g. Na...   Arduino megaAVR Watchdog & Resets, e.g. Nano Every ATmega4809 – Errata    • Arduino megaAVR Watchdog & Resets, e.g. Na...   Arduino megaAVR Brownout Detector, e.g. Nano Every ATmega4809 – First Look    • Arduino megaAVR Brownout Detector, e.g. Na...   Arduino megaAVR Analog Comparator, e.g. Nano Every ATmega4809    • Arduino megaAVR Analog Comparator, e.g. Na...   Arduino megaAVR Temperature Sensor (& ADC), e.g. Nano Every ATmega4809    • Arduino megaAVR Temperature Sensor (& ADC)...   Full Fly-by-Wire Electric Outboard (9): Voltage Measurement Circuit & Code    • Full Fly-by-Wire Electric Outboard (9): Vo...   My code https://drive.google.com/drive/folder... #arduino #arduinonano #avr #adc #tutorials #tutorial #how-to #robertssmorgasbord
