UART.repl_uart(), e.g. : change baud rate to 1.5M:from machine import UART
repl = UART.repl_uart()
repl.init(1500000, 8, None, 1, read_buf_len=2048)
UART.set_repl_uart(obj), the obj is UART object, the old one will be delete automatically(default REPL UART is UARTHS)clock module, move clock.clock() to time module, remove clock.sleep() function, you MUST use time.sleep_ms(n) to sleep n ms, time.sleep(n) means sleep n s， It's different with OpenMV's!sensor.run(0)
boot.py in _boot.py when BOOT key pushed down on power upBoard_Info object as var board_info in board.py, use it by:from board import board_info
print(board.BOOT_KEY)
the same as fpioa_manager
from fpioa_manager import fm
fm.register(board_info.LED_R, fm.fpioa.GPIOHS0)
or just import from fpioa_manager
from fpioa_manager import fm, board_info
print(board.BOOT_KEY)
fm.register(board_info.LED_R, fm.fpioa.GPIOHS0)
UART.any() 函数UART.repl_uart()， 比如：修改波特率位 1.5M：from machine import UART
repl = UART.repl_uart()
repl.init(1500000, 8, None, 1, read_buf_len=2048)
UART.set_repl_uart(obj) 来修改，obj 参数 是一个 UART对象，旧的使用在 REPL 上的串口对象将会被自动销毁（开机 REPL默认使用的串口是 UARTHS)clock 模块，因为它看起来比较奇怪，把 clock.clock() 函数移到了 time 模块，删除了 clock.sleep() 函数， 如果需要延时 n 毫秒请使用 time.sleep_ms(n) ， time.sleep(n) 只用来延时 n 秒， 注意这是和 OpenMV 不同的地方sensor.run(1)，当然可以调用
sensor.run(0) 来停止运行boot.py 的功能board.py 中新建了一个 Board_Info 对象： board_info，所以使用它如下：from board import board_info
print(board.BOOT_KEY)
fpioa_manager 也一样
from fpioa_manager import fm
fm.register(board_info.LED_R, fm.fpioa.GPIOHS0)
或者从 fpioa_manager 导入他们
from fpioa_manager import fm, board_info
print(board.BOOT_KEY)
fm.register(board_info.LED_R, fm.fpioa.GPIOHS0)
