So push aside your thoughts as to why I'm doing this, and why I'm not doing it via any other fancy method. from two to three AA batteries). And because the default value of bit 7 of the Fuse Low Byte is 0, division of the clock rate by 8 is enabled. Contrary to what the name suggests, the fuses configuration is reversible. (ATmega328p-PU) isn’t listed as being changed. Hello everyone, In this post I'm going to show you how to use a Atmega328p-PU as standalone i. These little devices are bread-board friendly (0. The internal RC oscillator frequency can in most AVRs be calibrated to within +/-1% of the frequency specified in the datasheet for the device. The various special features of Port B are elaborated in "Alternate Functions of Port B" on page 76 and "System Clock and Clock Options" on page 26. Includes 16MHz crystal oscillator. The ATmega328P will still work under this voltage, but only at 8MHz (which is the frequency of the Arduino Pro Mini 3. Runs up to 20MHz with external crystal. :-( That's weird, because pretty much every other ATmega supports running the timer crystal while in power-save mode. If it oscillates and the LED is lightening up, this means that the crystal is functioning. Details on using an ATmega328P-PU in a standalone mode are presented in Standalone ATmega328P-PU w Reset Button and LED tutorial.
