APT32F110X 系列串口功能强大: 可以完成STM32串口功能,驱动AT物联网模组不在话下。
资源串行通信接口:1 × I2C,3 x UART,1 x USART,1 x SPI,1 x SIO
通用异步收发器(UART)
3个通道
8位数据长度,支持校验位(奇偶校验,0/1校验)
单独的8x8位收发FIFO
可编程的波特率
同步异步收发器(USART)
编程实践:
时钟配置
void system_init(void)
{
CK_CPU_DISALLNORMALIRQ;
csi_iwdt_close();//close iwdt
csi_sysclk_config();//sysclk config
csi_get_sclk_freq();
csi_get_pclk_freq();
csi_tick_init();
csi_clk_calib();
CK_CPU_ENALLNORMALIRQ;
}
串口配置:115200波特率

花式打印表白啊,程序员哄女孩子的利器!!
先上图案:
代码实现很简单, printf打印就可以了:
int main()
{
//start_system();
system_init();
board_init();
csi_pin_set_mux(PB02, PB02_OUTPUT); //PA06 output
csi_pin_set_high(PB02); //PA06 output high;
