How do I connect "Ika-shouyu-poppoyaki” to LPC1114FBD48/302?

<Sorry, my English grammar is not good.>

Hi, everyone.

I have a LPC1114FBD48/302 SMD chip with converter board. And have a blue mbed LPC1768 for a writer. I want to write the sample program made by online mbed compiler like the below.

include the mbed library with this snippet

#include "mbed.h"
DigitalOut myled(xLED1);
int main() {
    while(1) {
        myled = 1;
        wait(0.2);
        myled = 0;
        wait(0.2);
    }
}

I write the code with reference to this figure. I try to connect the below pins. https://developer.mbed.org/media/uploads/ytsuboi/pinout_xpresso-20130816-o.png https://developer.mbed.org/media/uploads/okano/isp_connection_dip28.png

  • blue mbed LPC1768(Writer) -> LPC1114FBD48/302(Target)
  • GND -> Vss
  • VOUT -> Vdd
  • p28(TXD) -> PIO1_6(RXD)
  • p27(RXD) -> PIO1_7(TXD)
  • p26 -> PIO0_0(/RESET)
  • p25 -> ???

So I write the bin file by "Ika-shouyu-poppoyaki(I often use this)". https://developer.mbed.org/users/okano/code/ika_shouyu_poppoyaki/wiki/Homepage Cloud you tell me the may to connect the p25 of blue mbed. And my method is possible?
