WebMar 6, 2024 · Sorted by: 3. If you open up the chip datasheet, the maximum frequency of Atmega328P is 20 MHz. It will need at least 4.5V tor run at that speed. And if you want it to run at 20MHz with a 20MHz clock, the clock divider needs to be 1 so it does not run on slower clock than 20MHz. You can't change the clock speed by changing F_CPU. WebFeb 21, 2024 · No, you cannot set 6.4MHz on SPI with a default hardware arrangement. On the ATMega series of chips the SPI clock is generated by dividing the system clock (8 or 16MHz depending on if you have a 3.3 or 5V board) by one of: 2, 4, 8, 16, 32, 64 or 128.
