samd: Add new port to Microchip SAMDxx microcontrollers. Initially supporting SAMD21 and SAMD51. 2019-06-22 09:03:41 -04:00			`#define MICROPY_HW_BOARD_NAME "ItsyBitsy M4 Express"`
			`#define MICROPY_HW_MCU_NAME "SAMD51G19A"`
samd/clock_config: Add HW_DFLL_USB_SYNC and HW_MCU_OSC32KULP extensions. Two new compile flags are: MICROPY_HW_DFLL_USB_SYNC: Effective only if DFLL48 does not run from the crystal. It will synchronize the DFLL48M clock with the USB's SOF pulse. If no USB is connected, it will fall back to open loop mode. The DFLL48M clock is then pretty precise, but with a higher clock jitter at SAMD51 devices. MICROPY_HW_MCU_OSC32KULP: Effective only if the devics uses a crystal as clock source. Run the MCU clock from the ULP 32kHz oszillator instead of the crystal. This flag was added to cater for a interference problem of the crystal and Neopixel/Debug pins at Adafruit FEATHER Mx boards, which causes the board to crash. Drawback: ticks_ms() and time.time() vs. than ticks_us() and the peripherals like PWM run at not synchronous clocks. 2022-06-15 12:58:02 -04:00

samd/samd_qspiflash: Add QSPI flash driver and configure it accordingly. The QSPI driver provides the interface for using an on-board QSPI flash for the filesystem. It provides the same methods as the driver for the internal flash and uses the same name. Therefore, only one of the drivers for internal flash, SPI flash and QSPI flash must be enabled at a time.
