GM328 component tester problem - powers itself off too quickly, firmware 1.49m

[seanspotatobusiness]

I had a problem with the old original firmware on my GM328 component tester where, after booting, it would not let me select an item on the menu; it would move past the menu and say "Battery OK. Vext = 0mv" (with the Vext = 0mv part flashing) and I'd be unable to turn the unit off except by removing the power. I compiled 1.49m with the following settings and uploaded it to a different 328P chip:

Makefile (pastebin: https://pastebin.com/9N1VtdBH)
config.h (attached)
config_328.h (attached)

The problem now is that it switches off after less than a second following identification of a component, not giving enough time to read the screen. Video: https://youtube.com/shorts/xzoZdjnmPno - Anyone have any idea what could cause that?

The most relevant setting I know is #define POWER_OFF_TIMEOUT     60 which shouldn't power the unit off until 60 seconds have elapsed.

I don't know if this is your issue but worth a look. take a peek at ur config.h

see ur 60 sec timeout, great. But notice the comment about how it applies to "auto-hold" only...

Code: [Select]

/*
 *  Automatic power-off when no button is pressed for a while (in s).
 *  - applies to auto-hold mode only
 *  - uncomment to enable, also adjust timeout (in s)
 */

#define POWER_OFF_TIMEOUT     60
But these 'auto-hold' related settings are commented out... Should they be?

Code: [Select]

/*
 *  C/L monitors: auto hold
 *  - requires display with more than two text lines
 *  - uncomment to enable (one or more)
 */

//#define SW_MONITOR_HOLD_ESR   /* auto-hold ESR (C monitor) */
//#define SW_MONITOR_HOLD_L     /* auto-hold L (L monitor) */

/*
 *  Set the default operation mode to auto-hold.
 *  - instead of continous mode
 *  - uncomment to enable
 */

//#define UI_AUTOHOLD

I would give it a good clean.   Sometimes mine does that.
