Finally figured it out :lol:
Time and date was set, machine was powered down, and the time and date was still there when powered backup 8-)

If you look at my RTC guide and instructions there is a link to disk images with FGMC2 software on it.

I did look, but only saw the zip which is posted in the software section anyway.rubber_jonnie wrote: 13 Apr 2019 11:02 If you look at my RTC guide and instructions there is a link to disk images with FGMC2 software on it.

Hmm, I know I had an acc that put the time up on the menu bar, I thought it was on the disk. Will need to think about where I may have put it.

Re: ST RTC EXTERNAL BETA - WIP
How many people are interested in a kit ? Price will be about 25.. I may take some pre-orders for it as I don't want to invest in £12 a pop for a item for a stock item.

Re: ST RTC EXTERNAL BETA - WIP
Back to the plot...
I will build up maybe 5 of these this week and give them a test.. Then I will add them to my store.. I am not going to keep a large stock of these because of the price of the chips. I have not currently got many PCBs made anyway..

New chips from Farnell come... Still not having any luck...
The purple board was one of the older prototypes, that one was working until I changed the chip.. It hasn't worked since..
The middle one was the one I built up yesterday with the socket, I have not had this working at all yet..
The bottom one was the one I made up a few weeks ago which was working, until I change the chip, and it has not worked since.
Each of those boards as a new Farnell chip in it...So I do not know what the problem is :(

Re: ST RTC EXTERNAL BETA - WIP
Can you build the circuit on a breadboard to rule out any inconsistencies with PCBs?
And I know it's obvious but have you tried a different ST, in case its the ST that's killing the chips? Just a thought.

If it ain't broke, test it to Destruction.
