The mbed_TM1640 example code on the component page here should get you started. Here is a very basic version of the example code:

#include "mbed.h"
#include "TM1640.h"
 
Serial pc(USBTX, USBRX);

//TM1640_LM1640 declaration
TM1640_LM1640 LM1640(p5,p7);

int main() {   
    pc.printf("Hello World\r\n"); //    
    
    LM1640.cls(); 
    LM1640.setBrightness(TM1640_BRT3);    
 
    for (int cnt=0; cnt<=0xF; cnt++) {
       LM1640.locate(0);
       LM1640.printf("%02x", cnt);
      wait(0.2);
    }  
}
