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

T962A Controller Drop-In (using *STM32H7*) This is a drop-in replacement controller board for the T962A reflow oven, using the STM32H7

Finally got the 7.0" TFT working, wow does it look awesome, but it's big!  There was a discrepancy between the TFT datasheet and STMicro's datasheet, still not sure whom is right.. but whatever... it works..

Since the 7.0" looks so good, and works the same, I decided to see how to best make the board easy to switch between one or the other, so I had to slide the connectors around a tiny bit... plus since I was making a change I added a socket for 'ML2032' (rechargable CR2032 battery), and changed out the RTC clock to a true low-power crystal like the STM32 eval boards use.

This allows the board to have true battery backup for the Running Clock, so the thing can actually have a true time clock/calendar that doesn't lose it's settings :)

Just a nice extra I wanted to make work.

I'm cleaning up some more bugs and edge-cases that I identified, so will put up an initial software version prob. next week now, as I want to test it out some more, and possibly get that board revision back next week to test out..
