frequency can be displayed in Hz. The value is 700000. The best method is: Vcgencmd get_config arm_freq The running result is as follows: Arm_freq= 700 * Note: It may also display arm_freq = 0. I have seen such an output, but ignore it. The benchmark frequency shown here is 700 Mhz, which is also the Default Frequency of Raspberry Pi, but can it be faster? How to overclock Raspberry Pi You can use software to overclock Raspberry Pi, but some warning

Go to a script written in Python that outputs the various states and data of the Raspberry Pi, including CPU temperature, CPU usage, memory usage, and hard disk usage. Article from: Raspberry Pi Lab First, create a script: sudo nano get.py Second, paste the following code: Bash Import OS # Return CPU temperature as a character string Def getcputemperature (): res = Os.popen (' Vcgencmd measure_temp '). ReadLine () Return (Res.replace ("temp="
