Pol Isidor Posted December 8, 2019 Posted December 8, 2019 I need to change this port, couse it is in conflict with DS18B20 temperature sensor. I'm connected sensor on pin 37 (PA=20) with: Linux orangepipc 5.3.13-sunxi #19.11.3 SMP Fri Dec 6 14:09:51 CET 2019 armv7l GNU/Linux Linux orangepipc 5.3.13-sunxi #19.11.3 SMP Fri Dec 6 14:09:51 CET 2019 armv7l GNU/Linux but in this case I have a conflict when I type: root@orangepipc:~# armbianmonitor -m Stop monitoring using [ctrl]-[c] Time CPU load %cpu %sys %usr %nice %io %irq CPU C.St. 05:29:18: 1368MHz 0.49 27% 8% 13% 0% 4% 0% 21.5°C 0/8 05:29:23: 1368MHz 0.45 7% 3% 3% 0% 0% 0% 21.5°C 0/8 05:29:29: 1368MHz 0.38 6% 2% 3% 0% 0% 0% 21.5°C 0/8 05:29:35: 1368MHz 0.43 7% 3% 3% 0% 0% 0% 21.5°C 0/8^C It is exchanged (overwriten) the cpu temp sensor. How I did this? I edited the file: root@orangepipc:~# cat /boot/armbianEnv.txt verbosity=1 logo=disabled console=both disp_mode=1920x1080p60 overlay_prefix=sun8i-h3 rootdev=UUID=303f1c61-31c2-4d19-b229-300667548666 rootfstype=ext4 overlays=i2c0 i2c1 w1-gpio param_w1_pin=PA20 usbstoragequirks=0x2537:0x1066:u,0x2537:0x1068:u root@orangepipc:~# and add line: param_w1_pin=PA20 to force PIN 37. Why I'm doing this? On armbian with kernel v3.xxx what will be my already used backup system I'm already used pin 37 (PA20) Because if I need to go back to kernel version v3.xxx (I won't be physically home) I can ask just to change the backup SD card and not even cabel from PIN. On kernel v3.xxx I have not this conflict. I know that correct wiring on Kernel v5.xxx would be PIN 12 (PD14) without conflict with cpu sensor, but in that case I can not use on kernel v3.xxx I tried same to put those two lins in: /boot/armbianEnv.txt overlays=i2c0 i2c1 w1-gpio param_w1_pin=PA20 to force it but it do not "see" because result give next line: root@orangepipc:~# dmesg|grep w1 [ 9.913536] W1_SUNXI: Added w1-gpio on GPIO-20 on kernel v3.xxx How can I solve this conflict? Thx EDIT: Interesting is that command htop showing me the correct temperature of cpu sensor, but when I login to ssh it showing me on welcome screen temperature of DS18B20 sensor.

Yes I realised, that worked in that way that I enterd next values in file: cat /etc/modules w1-sunxi w1-gpio w1-therm I'm thinking is it posible to change/edit in the welcome screen and armbianmonitor -m the pointer to the cpu sensor? Because htop showing the right value.

Pol Isidor Posted December 8, 2019 Author Posted December 8, 2019 Hmm I do not know what to do with that file, I mean there is just one number inside: root@orangepipc:~# cat /sys/devices/virtual/thermal/thermal_zone0/temp 57027 root@orangepipc:~# cat /sys/devices/virtual/thermal/thermal_zone0/temp 57027 What is the meaning?
martinayotte Posted December 8, 2019 Posted December 8, 2019 Just now, Pol Isidor said: What is the meaning? This is CPU temp sensor. 57027 means 57.027 Celsius. So, maybe it is possible to change that symbolic link to another readout, the one from DS18B20 driver ... Although I didn't try it out, a script that would translate DS18B20 result found here : cat /sys/bus/w1/devices/28-000003ebdd28/w1_slave 56 01 4b 46 7f ff 0a 10 d1 : crc=d1 YES 56 01 4b 46 7f ff 0a 10 d1 t=21375 The 21375 is ambient temp 21.375 Celsius ...
Pol Isidor Posted December 8, 2019 Author Posted December 8, 2019 Yes but how to change in welcome screen for example to how me the real cpu temp and not from DS18B20 sensor? At me it showing: root@orangepipc:~# cat /sys/bus/w1/devices/28-0118674344ff/w1_slave 3e 01 4b 46 7f ff 0c 10 b0 : crc=b0 YES 3e 01 4b 46 7f ff 0c 10 b0 t=19875
