1. UART: ported to ASF4. Allow rx-only and tx-only. Add .baudrate r/w property. 2. Make NeoPixel timing deterministic by turning off caches during NeoPixel writes. 3. Incorporate asf4 updates: a. async USART driver b. bringing Atmel START configuration closer to what we use c. Clock initialization order now specified by CIRCUITPY_GCLK_INIT_1ST and _LAST. 4. supervisor/port.c: Move commented-out clock-test pin setting to correct location. |
