Allocate size bytes of RAM for the emergency exception buffer (a good size is around 100 bytes). The buffer is used to create exceptions in cases when normal RAM allocation would fail (eg within an interrupt handler) and therefore give useful traceback information in these situations. A good...
5. micropython.stack_use() 函数说明: 返回一个整数,表示正在使用的堆栈的当前量。示例: 代码语言:javascript 复制 >>>micropython.stack_use() 720 6. micropython.alloc_emergency_exception_buf(size) 函数说明: 设置紧急情况下的(栈溢出,普通RAM不足等)保险RAM分配,使在紧急情况下仍有RAM可用。

令牌化(Tokenize),即词法分析器(lexer)将Micropython语句拆分成令牌(Token)。 解析器(parser)根据令牌生成解析树(Parse Tree)。 解析过程由mp_parse函数(py/parse.c)实现。 3.1 令牌化 Micropython语句的令牌化由词法分析器完成,它从Micropython语句中逐个读取令牌并分类。令牌通常包括如下类别: ...
