Thanks for the actual numbers. Appreciate that.
Probably none that are spec'd that fast in my possession at the moment. Best I can do is try to drive an ILI9341 faster and see what happens. I have one installed on a PCB I can try.
Thanks for that. This is a helpful table.
The question somewhat remains - how fast can it really go? I'd think the actual I/O drivers on the outputs wouldn't be able to drive 120MHz without...
@KurtE, thanks for the tables. How are the QSPI memories supported ? Or the SD card on the T4.1? Some specialized driver?
If I wanted a QSPI ADC, yeah, I'd have to search for one. Probably...
I'd like to know the maximum SPI clock that a Teensy4 can support. Wading through some of the NXP documents (which is painful), the normal LPSPI clock is limited to f_peripheralclock/2. Can't seem...
