更改UART 硬件的波特率。 语法 C++复制 UART_SET_BAUD UartSetBaud;BOOLEANUartSetBaud( [_Inout_] PCPPORT Port, ULONG Rate ){...} 参数 [_Inout_] Port 指向_CPPORT结构的指针,该结构包含描述 UART 硬件的端口对象的地址。 Rate 要以位/秒为单位设置的波特率。
材料准备 AmebaD [ AMB23 / AMB21 / AMB22 / BW16 / AW-CU488 Thing Plus / AMB25 ] x 1 USB-TTL 适配器 x 1 范例说明 介绍 这个例子展示了如何为UART通信设置一个回调函数来处理UART数据。本例需要一个USB到TTL的适配器。确保已安装驱动程序并如图将其连接到Ameba板上。 流程...
I need to invert TXD line of the UART. This used to be achieved by uart_set_line_inverse(n, UART_INVERSE_TXD); But UART_INVERSE_TXD is not defined anymore in the new IDF. The doucmentation is also unclear: Choose the wires that need to b...

uart_set_pin(EX_UART_NUM, 17, 16, UART_PIN_NO_CHANGE, UART_PIN_NO_CHANGE); // works Ok so the documentation for uart_set_pin and UART_PIN_NO_CHANGE is a little confusing: "UART ** pin GPIO number, if set to UART_PIN_NO_CHANGE, use the current pin. " and my wild guess wa...
No need to. You can pass UART_PIN_NO_CHANGE as the pin number for the pins you do not want to use, and the uart code will not claim a GPIO for those. raoloka Posts:2 Joined:Mon Feb 11, 2019 11:22 pm Re: uart uart_set_pin forces me to set rts and cts, how to avoid losi...
这是C语言的宏定义, 跟STM32没有关系。 按正常的C语言来理解就可以了。具体含义确实如你所想,是实现 P31=n;命令
