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

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

FYI, it is MUCH MUCH nicer when using the NON-BRACKETED LCD screen, you can just use super-sticky adhesive tape on the back of the screen, to stick it right to the oven front panel.

I updated the pic in the project with how it looks, only a small bit of the lcd ribbon cable sticks out through the slot with it mounted in this fashion.

Now the only bad part is my oven has 4 ugly drilled holes from my mounting experiments, LOL.. oh well, I'll fill them in with some gray caulk to try and make it not so ugly.

i.e. definitely get this version of the TFT, ie without the mounting bracket:

(it's also in the BOM)

*** Also ****

It looks like it would be fairly easy to drop in the 7.0" TFT versus the 5.0", same resolution 800x480, but gives you a bit larger display..

I may indeed grab one of these and try it out, would require a simple change out of the two resistors that setup the voltage for the LCD display driver, as the 5.0" requires approx. 19.0VDC for the backlight, whereas the 7.0" only takes 9.6V..

I'll give it a try after I get an initial version of code working for this project
