Found here somebody that claims it should be possible, by adding a bitmask parameter to the command:
vcgencmd get_throttled 0x7
I understand this from his explanation:
- There are two persistent values stored in the Raspberry:
- Value A: Keep track whether the Raspberry has been throttled since reboot.
- Value B: Keep track whether the Raspberry has been since the bitmask has been used.
- You can get hold of both of these values:
- Get value A by calling the command without bitmask.
- Get value B by calling the command with bitmask.
If it works like this, then I think I should implement it in my node like this:
- Add a checkbox in my config screen "reset throttling status at every measurement".
- Apply the bitmask when the checkbox is selected.
- Add a warning in my readme file that only a single node-red-contrib-vcgencmd node is allowed to have this option. Indeed there is only 1 value B available in your Raspberry so the nodes would start resetting each others value B ...
Is there anybody that could check whether this theory is valid?
Not sure how I could 'easily' throttle my Raspberry temporarily to experiment with this.
