针对你的问题“segger_rtt_printf打印浮点数”,我将按照提供的提示进行回答: 确认segger_rtt_printf函数是否原生支持浮点数打印: SEGGER RTT(Real-Time Transfer)是一个高效的实时数据传输机制,通常用于嵌入式系统的调试。segger_rtt_printf是SEGGER RTT提供的一个类似于标准printf的函数,用于向主机发送格式化字符串。
它以非常高的性能结合了 SWO 和半主机的优势。但是在笔者使用时(RTT v758版本),其暂时不支持浮点数打印的功能。我们可以通过修改源码添加该功能。 跳转到RTT>SEGGER_RTT_printf.c>SEGGER_RTT_vprintf(unsigned, const char*, va_list*)函数中。 找到原代码中判断输出类型的部分,是使用switch-case判断类型的。 /...
