Hello,
I would like to set the CPU frequency of my ESP32 custom board under 80Mhz for lowering power consumption. I'm using the PlatformIO IDE with Arduino framework.
I tried the setCpuFrequencyMhz() function but getCpuFrequencyMhz() always returns 240Mhz whatever I set with setCpuFrequencyMhz().
But by using board_build.f_cpu = 80000000L, it is working. However, the board crashes with board_build.f_cpu = 40000000L (40Mhz). Is there a way to lower the frequency under 80Mhz ?
Have a nice day
CPU frequency under 80Mhz
Re: CPU frequency under 80Mhz
Is your code using wifi or bt/ble? Because in this case 80MHz is minimum you can go.AyubowanPro wrote: ↑Wed Aug 03, 2022 9:23 amBut by using board_build.f_cpu = 80000000L, it is working.
