## ESP32 Interupt Issues
* ESP32 Thread I started: https://esp32.com/viewtopic.php?f=12&t=21855
* " Consider 74ls373 to latch the value to be processed by software."
* It might also be worth trying ESP32's assembly high-level interrupts. I've never used them personally, but they can allegedly give interrupt latencies that are significantly lower than the ~2us for regular ESP32 C interrupts.
* See: https://esp32.com/viewtopic.php?t=422
