if (UART2.ReceiveFinish) { UART2.ReceiveFinish = 0; printf("You Input data:%d\r\n", UART2.Rxbuf[0]); SetpMotorRun(UART2.Rxbuf[0]); UART2.Rxbuf[0] = 0; UART2.RXlenth = 0; }

这段代码是一段嵌入式系统的代码，主要作用是接收来自UART2串口的数据，并把数据发送给步进电机控制函数SetpMotorRun()进行处理。当UART2接收完成后，会触发中断并设置UART2.ReceiveFinish标志位。在主程序循环中，如果检测到UART2.ReceiveFinish被设置，则说明接收完成，可以对接收到的数据进行处理。这段代码中使用了printf()函数将接收到的数据打印出来，方便调试。同时，将接收缓冲区清零以备下次接收。

以下是将上述STM32代码移植到BL618进行改写后的代码：

#include "bl602.h"
#include "bl_adc.h"
#include "bl_gpio.h"
#include "bl_mtimer.h"
#include "stdio.h"

#define PRESS_MIN 20

long map(long x, long in_min, long in_max, long out_min, long out_max);

int main(void)
{
    bl_mtimer_init();

    bl_gpio_enable_output(PIN_11, 1);

    bl_adc_init();

    bl_adc_config_t cfg = {
        .inputMode = ADC_INPUT_SINGLE_END_MODE,
        .input = ADC_INPUT_CH0,
        .clkDiv = ADC_CLK_DIV,
        .resolution = ADC_RESOLUTION,
        .refSel = ADC_VREF,
    };

    bl_adc_channel_config(ADC_CHANNEL, &cfg);

    printf("Test start\r\n");

    while (1)
    {
        bl_adc_start();

        while (!bl_adc_fifo_data_count())
        {
            bl_mtimer_delay_us(100);
        }

        uint16_t value_AD = bl_adc_read_fifo_data();

        int VOLTAGE_AO = map(value_AD, 0, 4095, 0, 3300);

        long PRESS_AO = 0;

        if (VOLTAGE_AO < VOLTAGE_MIN)
        {
            PRESS_AO = 0;
        }
        else if (VOLTAGE_AO > VOLTAGE_MAX)
        {
            PRESS_AO = PRESS_MAX;
        }
        else
        {
            PRESS_AO = map(VOLTAGE_AO, VOLTAGE_MIN, VOLTAGE_MAX, PRESS_MIN, PRESS_MAX);
        }

        printf("AD value = %d, voltage = %d mV, pressure = %ld g\r\n", value_AD, VOLTAGE_AO, PRESS_AO);

        bl_mtimer_delay_us(500000);
    }
}

long map(long x, long in_min, long in_max, long out_min, long out_max)
{
    return (x - in_min) * (out_max - out_min) / (in_max - in_min) + out_min;
}

在BL618中，需要使用`bl_adc_init()`进行ADC模块的初始化，并通过`bl_adc_channel_config()`配置ADC通道。需要注意的是，BL618的ADC模块不支持差分模式，因此需要将原来的差分模式改为单端模式。在进行ADC转换时，可以使用`bl_adc_start()`触发转换，并通过`bl_adc_fifo_data_count()`和`bl_adc_read_fifo_data()`获取转换结果。此外，由于BL618中没有提供延时函数，需要使用`bl_mtimer_delay_us()`进行延时。
