    @Paul, don't know when you plan to release a non-beta TD version.. we have to take a look at the audio-lib, first. Looks like I have added some bugs for T3 :-( Mainly a different sequence of code lines, which i...

    Got it working with two Teensy 3.6, and TD 1.45, but did not find the bug in the new version so far. Well, at least I can say I have a way to test it, and can confirm, the T3.x does not need MCLK in slave mode and...

    @defragster: Tried with a newer compiler? Anyway, we have to live with the old 5.4, so we should try to find a workaround.

    The Teensy is the problem, not the Audio Shield. The 3.6's I2S device does not like the overclocking and has hefty problems creating the cock signals > 192MHz. So, I don't think that it works better with the PT8211.

    @Bob, DD4WH's Software can do FM (80-108 MHz), the SGTL5000 gets overclocked to 234KHz in this mode - have you tried to overclock the WM8731?

    The code is: unsigned freq = 15000000; //15MHz or any other.. works up to F_BUS_ACTUAL / 2 = 75MHz (without overclocked F_BUS) TMR3_CMPLD10 = F_BUS_ACTUAL / 2 / freq - 1; Edit: Verified with my scope. It...

    Hm, I think I have an Idea what the problem is.. I think, I can repair it tomorrow or on wednesday. In addition, for T4, the I2S Slave-code is still a TODO. Unfortunately, next week, I'm on a short vacation, and...

    Hi Kurt, I modified now your graphicstest (attached to this post). Apart form the cache-issue (which is not really an issue, because we know how to solve it!), it stops/hangs: ILI9341 Test! After TFT Begin 13...

    Not sure.. I'll try to compare the versions before and after t4.. I don't have hardware for slave-mode. Maybe a T3.2 as master, connected to a second 3.2 or 3.6 as slave? If that works, I can test the T4, too.

    Thank you Kurt, I'll try that when I'm back home. I was pretty sure that it was no caching issue, but maybe I was wrong.

    @Kurt, I'm having problem, getting updateScreenAsync(true) to work, with your ILI9341_t3n library. Is the "master" branch the right one? Does it work, or am I doing something wrong? It's not the cache - it just...
