How use Grove Doppler Radar (BGT24LTR11) on Md

Hello, someone can help me to convert this code in arduino to mbed?

#include “GBT24LTR11.h”

#ifdef AVR
#include <SoftwareSerial.h>
SoftwareSerial SSerial(2, 3); // RX, TX
#define COMSerial SSerial
#define ShowSerial Serial

GBT24LTR11<SoftwareSerial> GBT;

#endif

#ifdef ARDUINO_SAMD_VARIANT_COMPLIANCE
#define COMSerial Serial1
#define ShowSerial SerialUSB

GBT24LTR11<Uart> GBT;

#endif

#ifdef ARDUINO_ARCH_STM32F4
#define COMSerial Serial
#define ShowSerial SerialUSB

GBT24LTR11<HardwareSerial> GBT;

#endif

void setup() {
// put your setup code here, to run once:
ShowSerial.begin(9600);
COMSerial.begin(115200);
GBT.init(COMSerial);
while (!ShowSerial)
;
while (!COMSerial)
;
/*
MODE 0 -->detection target mode
MODE 1 -->I/Q ADC mode
*/
while (!GBT.setMode(0))
;
}

void loop() {
// put your main code here, to run repeatedly:
uint16_t state = 0;
ShowSerial.print(“target speed:”);
ShowSerial.println(GBT.getSpeed());
state = GBT.getTargetState();
//2 → target approach
//1 → target leave
//0 → Not Found target
if (state == 2) {
ShowSerial.println(“target approach”);
} else if (state == 1) {
ShowSerial.println(“target leave”);
}
delay(200);
}
