【上海航芯ACM32F403开发板首发试用】UART2使用

本次试用的上海航芯ACM32F403[开发板]板载一款ACM32F403RET7 MCU。该系列MCU具有非常丰富片上外设，并且具有较高的系统频率180MHz，[ARM]v8-M 架构同时支持Cortex-M33 和Cortex-M4F 指令集，192KB SRAM 512KB eFlash的片上存储资源，性能非常强悍！

串口配置如下：
#define UART_BAUD_RATE 9600

UART_HandleTypeDef UART2_Handle;

void Uart_Init(void)

{

UART2_Handle.Instance = UART2;

UART2_Handle.Init.BaudRate = UART_BAUD_RATE;

UART2_Handle.Init.WordLength = UART_WORDLENGTH_8B;

UART2_Handle.Init.StopBits = UART_STOPBITS_1;

UART2_Handle.Init.Parity = UART_PARITY_NONE;

UART2_Handle.Init.Mode = UART_MODE_TX_RX_DEBUG;

UART2_Handle.Init.HwFlowCtl = UART_HWCONTROL_NONE;

HAL_UART_Init(&UART2_Handle);     
/* ENABLE FIFO */ 
HAL_UART_Enable_Disable_FIFO(&UART2_Handle,FUNC_ENABLE); 

  printfS("This is UART2  \r\n");  
/* UART_DEBUG_ENABLE control printfS */     
printfS("MCU is running, HCLK=%dHz, PCLK=%dHz\n", System_Get_SystemClock(), System_Get_APBClock());       
	printfS("Please enter any String/Data \r\n");

}

while(1)
{
HAL_UART_Receive_IT(&UART2_Handle, gu8_RxBuffer, sizeof(gu8_RxBuffer), UART_RX_FIFO_1_2); <= sizeof(gu8_RxBuffer)

while(1)  
			{
				while (!gu32_RxCpltStatus2);
			
				gu32_RxCpltStatus2=false;
			
				memcpy(gu8_TxBuffer, gu8_RxBuffer, UART2_Handle.lu32_RxCount);
			
				HAL_UART_Transmit_IT(&UART2_Handle, gu8_TxBuffer, UART2_Handle.lu32_RxCount, UART_TX_FIFO_1_2); 
			
				while (!gu32_TxCpltStatus2);  
			
				gu32_TxCpltStatus2 =false;
			
				break;		   
			}
		}
	}

然和打开串口监视工具波特率设置9600；发送string“hellow ACM32F403

”mcu收到并回复收到的字符。
