WebTo check that it is oscillating you need a high impedance probe (eg. oscilloscope probe on x10 position) connected to pin 16 of the ATmega. You should see a sine wave with peak-to-peak amplitude of at least 2V. If you just see a DC level of around 1~2V then the crystal is not oscillating, either because it is faulty or not connected.
Crystal not oscillating
Did you know?
WebAdsorption can produce soft, or viscoelastic films and the resulting layer may not fully couple to the oscillating crystal. This can lead to dampening, or energy loss, of the oscillation. The mass of such films cannot be determined accurately by measuring the frequency change alone. WebJun 14, 2024 · The external oscillator has the advantage of providing a low-power highly accurate clock source needed for real-time clock (RTC), clock/calendar, and other timing functions. The HSE and LSE can be provided from an external source using the OSC_IN and OSC32_IN pins (bypass mode) or a crystal/ceramic resonator.
