How do i monitor freq and temp on OP+ (H3)

Vlad

Here is my bash script, namely sensors.sh:

1. #/bin/bash
   
2. while (true); do
   
3.     cpu_cur=$(( `cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq` / 1000 ))
   
4.     cpu_max=$(( `cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq` / 1000 ))
   
5.     cpu_min=$(( `cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq` / 1000 ))
   
6.     cpu_cur="$(printf "%4s" $cpu_cur)"
   
7.     cpu_max="$(printf "%4s" $cpu_max)"
   
8.     cpu_min="$(printf "%4s" $cpu_min)"
   
9.     tempr=`cat /sys/devices/virtual/hwmon/hwmon1/temp1_input`
   
10.     tempr="$(printf "%3s" $tempr)"
    
11.     ddr_cur=$(( `cat /sys/devices/platform/sunxi-ddrfreq/devfreq/sunxi-ddrfreq/cur_freq` / 1000 ))
    
12.     ddr_max=$(( `cat /sys/devices/platform/sunxi-ddrfreq/devfreq/sunxi-ddrfreq/max_freq` / 1000 ))
    
13.     ddr_min=$(( `cat /sys/devices/platform/sunxi-ddrfreq/devfreq/sunxi-ddrfreq/min_freq` / 1000 ))
    
14.     ddr_cur="$(printf "%4s" $ddr_cur)"
    
15.     ddr_max="$(printf "%4s" $ddr_max)"
    
16.     ddr_min="$(printf "%4s" $ddr_min)"
    
17.     echo -ne "  CPU (MHz): $cpu_cur (min $cpu_min, max $cpu_max)  TEMPERATURE: $tempr  MEMORY (MHz): $ddr_cur (min $ddr_min, max $ddr_max)   "\\r
    
18.     sleep 0.2
    
19. done
    

Copy code

It was designed by reverse engenering. is there docs by officials?
