…smission. The protocol has to be continuous therefore next buffer filling is time critical. This is now below (high freq) times for capacitive touch and display and will compete with the (6 byte rx buffer nRF52) uart and pin interrupts. On plus side there are only a handful of interrupts per use of neopixel_send_buffer(). lancaster-university#475

This is a small change in terms of code with interrupt priority increase by a numerical decrease from 3 to 2 for
PWM2_IRQnused for the code under theneopixellibrary. This could have large implications for MicroPython so is worthy of a thorough review by someone with substanital knowledge of the internals including CODAL.Partner PRs:
