Gab, I have a xprotolab and xprotolab portable, both with v2.25 of the firmware. ?I noticed that there are times when pressing MENU to turn off the scope, it will not do so UNLESS the scope is triggered.
So, if there is not trigger condition, I cannot turn off the scope, no mapper how long I hold the MENU key.
Any thoughts?

Yes, that is how it is currently implemented. I will try to find an alternative way to solve this.
The reason is that when the device is not being triggered, the firmware is on a very tight loop waiting for the trigger event./\r\n/If I enable a timer interrupt to check if the button is still being pressed, then there would be increased trigger jitter if the trigger event happens to occur at the same time of the interrupt.

Well, at least I know I'm not crazy! I appreciate you looking into it./\r\n//\r\n/
