v0.3.0

24cd401

v0.3.0 Pre-release

Pre-release

New Features

Adapt for OpenMV IDE( Can not use the original version, in order to adapt MaixPy, there are modifications to the IDE source code)
Add UART.any()
Add get REPL UART object by 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)

Add set REPL UART, by UART.set_repl_uart(obj), the obj is UART object, the old one will be delete automatically(default REPL UART is UARTHS)

API Changes

Remove 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!
Auto run sensor after sensor reset, you can stop sensor by sensor.run(0)
Remove : rewrite boot.py in _boot.py when BOOT key pushed down on power up
Create Board_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)

Fix

Fix touchscreen module compile error when not select it in makefile

Docs

新特性

适配 OpenMV IDE （OpenMVP官方IDE不能使用，为了适配 MaixPy 对 IDE 源码有修改）
添加UART.any() 函数
增加获取交互串口对象（REPL UART object）的方法： 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)

增加重新设置串口对象的接口，通过 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)

API 改动

移除了 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
在摄像头初始化后（sensor.reset) 会自动启动运行，不需要再调用 sensor.run(1)，当然可以调用
sensor.run(0) 来停止运行
删除了开机按下 BOOT 键会重新刷写 boot.py 的功能
在 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)

修复

修复在 Makefile 选择不使用 touchscreen 模块时编译出错的问题
