Is there any way to switch between configure_in_port_strobed

Post by brucekuo »

I want to use StartKIT to simulate a SRAM, so I will use input OE, input WE, input Clock, and bi-direction Data pin.

Diagrammatic Sketch as below:

i.MX6 (MCU)<----->StartKIT (SRAM)

Now, I can simulate SRAM Reception and SRAM Transmission respectively, mean that there are two programs,

one is SRAM Reception, the other is SRAM Transmission.

And then, I use configure_in_port_strobed_slave() to do SRAM Reception, and use configure_out_port_strobed_slave()

to do SRAM Transmission.

Now I have a problem, is there any way to switch between configure_in_port_strobed_slave() setting and configure_out_port_strobed_slave setting in the run time?

My Reception and Transmission Function as below:

void Reception Function(in port p_WE_Valid, buffered port:32 p_Data, clock clk, in port p_In_Clock, unsigned short * DataBuf)

{

        configure_clock_src(clk, p_In_Clock);
        configure_in_port_strobed_slave(p_Data, p_WE_Valid, clk);
        set_port_inv(p_WE_Valid);
 
        clearbuf(p_Data);
 
        start_clock(clk);
 
        for (int i = 0; i < MAX_DATA_SIZE; i++)
       {
              p_Data :> value;
 
              DataBuf[inidx] = value;
 
              inidx++;
 
       }
       inidx *= (inidx < MAX_DATA_SIZE);
}

void Transmission Function(in port p_OE_Valid, buffered port:32 p_Data, clock clk, in port p_In_Clock, unsigned short * DataBuf)

{

        configure_clock_src(clk, p_In_Clock);
        configure_in_port(p_OE_Valid , clk);
        configure_out_port_strobed_slave(p_Data, p_OE_Valid, clk, 1);
 
        set_port_inv(p_OE_Valid);
        set_port_inv(p_In_Clock);
 
        clearbuf(p_Data);
 
        start_clock(clk);
 
        for (int i = 0; i < MAX_DATA_SIZE; i++)
       {
              p_Data <: DataBuf;
       }
}

Any help is appreciated,

Best Regards,
