Re: [ts-7000] Re: TS-7800 wake from sleep using dio_04 (interrupt)

Hello,

  We have had similar issues with the wake up interrupt, but hadnât found any way to get it working and without a new AVR firmware this wonât work. TS know about the problem and they told us that they will work on it. A relay solution might work

Hello?
Is there a different group for the TS-7800; there seems to be alot of 7200 & 7400 questions?

I've attempted to contact TS for the past few days about this issue to no avail. Just wondering if anyone has had similar experience and possibly a work around for interrupt driven wake-up for TS-7800

I'm now looking into the ATMEGA48V AVR_RESET# (PC6) signal; or possibly some io driven relay controlling the pwr directly...

Unfortunate when the documentation says it supports such a feature :[

thanks

This causes the ATMEGA48V micro to cut power to the ARM, and sleep in a very low power mode ~200uA. It works great... well the sleep does. The details described from this post here:

The current draw ramps back up, the board GRN LED blinks, but the board does not reboot; it just prints a single garbage character out to serial COM1 and hangs.
