usart_sendbyte 函数是用于通过指定的 USART(通用同步异步接收发射器)发送一个字节数据的函数。下面是对该函数的详细解释: 用途: 该函数的主要用途是通过 USART 发送一个字节的数据。这在与外设或上位机进行通信时非常常见,比如发送控制命令或数据包。 函数参数 usart_typedef * pusartx 的含义:
USART_StopBits:停止位设置,可选0.5 个、1 个、1.5 个和2 个停止位,它设定USART_CR2寄存器的STOP[1:0] 位的值,一般我们选择1 个停止位。 USART_Parity:奇偶校验控制选择,可选USART_Parity_No(无校验)、USART_Parity_Even(偶校验) 以及SART_Parity_Odd(奇校验),它设定USART_CR1 寄存器的PCE 位和PS 位的...

定义和声明用是否有extern来区分,有extern的是声明,多次出现也无所谓;没有extern的是定义,这个只能出现一次!切记。..\OUTPUT\USART_RX.axf: Error: L6200E: Symbol send_waterlevel0 multiply defined (by waterlevel.o and main.o).这个错误怎么解决啊?
