【东软载波ESF0654 PDS开发板活动】+串口通讯
1，考虑到板子上串口2和ES-LINKII的串口转USB有现成的连接：只要跳线就OK。
2，那就用这个接口。
3，接口IO为PD２　TX2 PC 12 RX2
4,采用例子\ES-PDS-ES32F0654\ES32_SDK_V1.04\Projects\ES32F065x\Examples_MD\UART
5，修改如下：
main.h:
#define UART2_TX_PORT       GPIOC
#define UART2_TX_PIN       MD_GPIO_PIN_12
#define UART2_RX_PORT       GPIOD
#define UART2_RX_PIN       MD_GPIO_PIN_2
main.c:
md_uart_init_t init;
uint8_t tx_buf[64];
uint8_t rx_buf[64];

void uart_pin_init(void)
{
      md_gpio_init_t x;

      /* Initialize tx pin */
      x.mode = GPIO_MODE_OUTPUT;
      x.odos = GPIO_PUSH_PULL;
      x.pupd = GPIO_PUSH_UP;
      x.odrv = GPIO_OUT_DRIVE_NORMAL;
      x.flt  = GPIO_FILTER_DISABLE;
      x.type = GPIO_TYPE_TTL;
      x.func = GPIO_FUNC_5;
      md_gpio_init(UART2_TX_PORT, UART2_TX_PIN, &x);

      /* Initialize rx pin */
      x.mode = GPIO_MODE_INPUT;
      x.odos = GPIO_PUSH_PULL;
      x.pupd = GPIO_PUSH_UP;
      x.odrv = GPIO_OUT_DRIVE_NORMAL;
      x.flt  = GPIO_FILTER_DISABLE;
      x.type = GPIO_TYPE_TTL;
      x.func = GPIO_FUNC_5;
      md_gpio_init(UART2_RX_PORT, UART2_RX_PIN, &x);

      return;
}

/**

int main()
{

      md_init_1ms_tick();

      /* clear md_uart_init_t structure */
      memset(&init, 0x0, sizeof(md_uart_init_t));

      init.parity    = MD_UART_PARITY_NONE;
      init.fctl       = MD_UART_FLOW_CTL_DISABLE;
      md_uart_init(UART2, &init);

      /* Send a message */
      md_uart_send_data8(UART2, tx_buf[0]);
      /* Receive a message */
      rx_buf[0] = (uint8_t)md_uart_recv_data8(UART2);

      while (1) {
            uint8_t index=0;
            if(index >=64)
                     index  =0;
            /* Send a message */
            /* Receive a message */
            rx_buf[index] = (uint8_t)md_uart_recv_data8(UART2);
            tx_buf[index]= rx_buf[index];
            md_uart_send_data8(UART2, tx_buf[index]);
            index++;

      }
