stm32中字符串拼接

在STM32中进行字符串拼接可以使用sprintf函数。该函数可以将多个字符串或者变量拼接成一个字符串。你可以使用该函数来将多个字符串或变量拼接成一个字符串，并将结果保存在一个字符数组中。比如，你可以使用以下代码进行字符串拼接：

#define u8 unsigned char
#define u32 unsigned int
#define u16 unsigned short int

u8 Rx_data3=0x00, Rx_data2=0x8D, Rx_data1=0x2C;
char spiBuf<span class="em">1</span><span class="em">2</span><span class="em">3</span>
