A project log for T962A Controller with 5"/7" Touch TFT (*STM32*)

Alright!  

Schematic/Board design is finally complete.  I still have some notes/comments/etc to cleanup in the eagle schematic file, but wanted to post it so at least anyone interested can at least get an idea of the size... I haven't done the BOM yet, that will take some time.

So EAGLE files are posted, along with a link to the initial Github repo, which currrently just has the eagle files, and a jpg of the schematic, and also the OshPark link for the board I had made.  I'm *SURE* you can get this board made cheaper somewhere else, I am just happy with Osh and their reliability, but $200 for this board is very very steep, i'm sure other places can do much much cheaper. 

You'll notice the odd 'L-shaped' board, but that is so it can mount cleanly on the 6 mounting posts already there on the inside of that cover for the oven, and when the LCD is mounted on the outside, you dremel a slot where the LcD connectors pass through and connect up to the board.  (I'll post some pics shortly of how this looks)

Just built the final version, using 64MB SDRAM, and all other fixes, and it's working without issues, everything looks great.

I'm currently working on the touch screen menus and things using the STemWin Graphics IO package, which is working great.

Hopefully within the next month or less I will have a first working version and will have the initial software repo to post... hoping that will happen!

But definitely not too far away, that is for sure, as I have many of the LCD screens already working, just trying to design some decent first drafts, and then get an actual run going.
