Passing a C array, string or otherwise, into a non-template function effectively devolves the array to a pointer so the function doesn't know what the size of the array unless passed as a separate parameter. std::fixed_string would "remember" its size, just as std::array does. ...
I have a problem with the example code BLE_OTA_FixedStack_Bootloader/Bootloadable. I program on the CY8CKIT-042-BLE with a CYBLE-022001-Eval plug I just modified P2.7 to P3.5 and P2.6 to P3.4 to connect the switch and the Led. So I follows the PDF and the bootloader and the b...
CAsyncAlgo { public: using Data_t = size_t; private: static constexpr size_t mNbData = 1024; size_t mWorkingIndex = 1; size_t mBufferIndex = 0; // type of data buffer using DataBuffer_t = std::array<Data_t, mNbData>; size_t...
这一设计使得SmallVector在元素数量较少时，性能表现更佳。此外，SmallVector通过减少频繁的内存分配与释放操作，进一步提升了性能。在项目中，如果存在较多的小容器，使用SmallVector能有效提升整体性能。SmallVector的核心实现包括一个VectorView模板类，用于提供通用方法，如data()、size()等，并通过一个buffer_s...
data(); buffer_capacity = N; } private: size_t buffer_capacity = 0; AlignedBuffer<T, N> stack_storage; } 可以看到SmallVector的构造函数中首先是将ptr指向了stack_storage所在的内存。当然在后续的往SmallVector塞入数据的时候会重新动态分配对应的内存。在这补充reserve()的实现,应该会方便你理解这个再...

This eliminates the possibility of conflict between message buffer and operating heap memory since std::array alloctes on stack. See writeup on Using CCM Memory. Eg instantiating a queue with:constexpr size_t queueSizeMaxChars = 30000; fssb::FixedSizeStringBuffer<queueSizeMaxChars> cmdHistory;...
Hi, first post here, I've also raised thisquestion on stack overflow. I'm getting crashes from a fixed size array even though I thought I'd protected the index from going out of range. The array updates in a loop, like a ring buffer. ...
