9x Exit button size.

Hi friends. A friend of mine has the exit button damaged. It needs to be replaced. Could you tell me the size? I guess it is a SMD switch, 4.5mm? How long?
Thanks!

Re: Voltage drop in 9x

Easy to add the extra build, so I've posted a '128 version for the Green processor created by doing a full build of all versions, so it will be updated and released with all the other versions. Please could you check it out. It has the software watchdog, extended to 350mS, with the actual hardware ...

Re: Voltage drop in 9x

I'll think on what to do permanently. Maybe I need to build a '128 version specifically for the Green processor. I think that will be the easiest solution since I don't like the idea of adding the 300mS software watchdog to the standard '128 version as that would increase the watchdog timeout to 0....

Re: Voltage drop in 9x

I'm wondering if the Green chip is clocking the watchdog faster, and using some unused bits in the configuration register to set up the longer timeouts. Either that, or the watchdog is just not working properly. I've just posted a new test version that includes a 300mS software driven watchdog, whi...

Re: Voltage drop in 9x

I think this GREEN chip thingy might not be an 100% clone of the m128, and that might be the problem. João That is what I think...

Re: Voltage drop in 9x

I've just posted a special test version, for the '128, with the watchdog set to 2 seconds instead of the normal 0.5 seconds. I've done this in case the "Green" processor watchdog is running fast, causing a watchdog reboot when it shouldn't happen. Mike Flashed! I think we might be on the ...

Re: Voltage drop in 9x

Sounds like you may be getting a watchdog reboot. On a normal start, the battery voltage is read, then new values displayed are the average of the current value and the new value. On a watchdog reboot, the voltage is likely left at 0, so the first average is half the battery voltage (5.2?), and wil...

Re: Voltage drop in 9x

The voltage drop happens like once of every 10-15 times or so I go to the mixer menu or radio/model setup menu. Sometimes I even see the splash screen for a fraction of second.
