    Thanks for testing. My 5 inch RA8875 arrived yesterday. Looks like it has a different pinout, so I'm going to put off testing it for a while. I'm feeling pretty good about RS8875 - certainly good...

    I'm wrapping up 1.53 now. Let's wait just a day or two, then ask Ivan to take a look at why it's not compiling on PlatformIO.

    Probably not for 1.53. I did bring in NativeEthernet and did some testing with it today.

    I have 3 issues remaining on my list, all involving the installer. Was planning to package up 1.53-beta3...

    Let's wait to change the SPI initialization, until after 1.53. Committing a late change to the empty end() function doesn't seem risky, but changing how the hardware it initialized is more risk than...

    Looking at the "Kurts_ILI9488_t3n_FB_and_clip_tests" example, I don't understand why it's including extRAM_t4.h. It creates an "ext_mem" object which seems to be only used once for...

    We're only a matter of days away from a non-beta release. The last thing I'm going to do right now is make changes in that critically important code, no matter how trivial they may seem.

    Well, maybe I have a flaky Buydisplay? I'm running the mangGauges_800x480 example on Adafruit's RA8875 (which measures about 5 inches) . It works fine with Teensy 4.0 at 600 MHz or even overclocked...

    I don't think it's the SPI clock speed. I edited the code to increase to 22 MHz, and I used my scope to check it really was 21.8 MHz. At 528 MHz and 21,8 MHz SPI clock, it runs reliably. But with...

    Looks like we may have timing issues. This mangGauges_800x480 example works with Teensy 4.0 when the CPU speed is set to 528 MHz or slower, but fails if 600 MHz or faster.

    I found a 7 inch Buydisplay RS8875 and wired it up. Looks like "tft.GPIOX(true);" has no effect. It should probably be in all the examples with a comment that it's needed for Adafruit's RA8875.
