Web6 mei 2024 · To a large extent, the choice of crystal frequency is pretty arbitrary. I bought a large quantity of 13.5MHz crystals once, because they were cheap. (however, this was stupid. Because a crystal is cheap, anyway.) The Arduino probably uses 16MHz because that was the maximum frequency for the ATmega8 chip used on the first Arduino. WebWhich mode to be select, it all depends upon the desired output configuration. LP: Selects the lowest gain setting for the internal inverter- amplifier. Lowest current consumption of the three modes. Designed to …
