The Envision kit comes with a Newhaven NHD-4.3-480272EF-ATXL#-CTP. I'm trying it out with an EastRising? SH500J15Z. It's pin-compatible with the original display, just a little taller. 5" instead of 4.3".
Programs I wrote for the original work right away on the new display. Except for touch. It doesn't have a capacitive touch front pane. I ordered one. Hopefully it fits and is compatible with the RX65N graphics layer ...
For posterity, I'm posting the settings of the Renesas QE Display tuning app, that give good results:
Not the most interesting post. But it took a good day to get everything working. And may help someone that's trying to hook a similar display to the RX65N. (or myself in a few weeks when I forgot all of this).
