APT32F110x 系列串口功能強(qiáng)大：?可以完成STM32串口功能，驅(qū)動AT 物聯(lián)網(wǎng)模組不在話下。

資源串行通信接口：1 × I2C，3 x UART，1 x USART，1 x SPI，1 x SIO

通用異步收發(fā)器（UART）

(相關(guān)資料圖)

? 3個通道

? 8位數(shù)據(jù)長度，支持校驗(yàn)位(奇偶校驗(yàn)，0/1校驗(yàn))

? 單獨(dú)的8x8位收發(fā)FIFO?

? 可編程的波特率

同步異步收發(fā)器（USART）

? 1個通道

? 支持5、6、7和8位數(shù)據(jù)長度?

? 單獨(dú)的8x8位收發(fā)FIFO

花式打印表白啊，程序員哄女孩子的利器！！

先上圖案：

代碼實(shí)現(xiàn)很簡單，?printf打印就可以了：

//start_system();

system_init();

board_init();

csi_pin_set_mux(PB02, PB02_OUTPUT); //PA06 output

csi_pin_set_high(PB02); //PA06 output high;
