Information

This page is for GR-PEACH rev.E and GR-PEACH rev.C.
If your GR-PEACH is rev.B, go to Information of GR-PEACH rev.B. To identify GR-PEACH revision, see here.

Preparation

Install the USB serial communication driver

Only for Windows(R) user:

  1. Connect GR-PEACH and PC with USB cable which is closer to push switch.
  2. After the mount GR-PEACH as "MBED" volume label, install this driver.

Register GR-PEACH as your target board

  1. Check if the root folder of GR-PEACH mass storage drive has "mbed.htm" .
  2. Open "mbed.htm".
  3. Click "Add to your compiler" button in "mbed.htm".

Build and Run

  1. Click "import" button of "mbed_blinky" below.

    Import programmbed_blinky

    The example program for mbed pin-compatible platforms

    Last commit 08 Apr 2019 by Mbed

  2. Check "Update all libraries to the latest version".
  3. Get the source code by clicking "Import" button.
  4. Select "mbed" library and delete it as shown below.
    __Since "mbed lib" was updated from rev.B to rev.C on 2015 Apr 14th, this procedure is not needed now.__

  5. Import mbed-src rev.C library.
    __Since "mbed lib" was updated from rev.B to rev.C on 2015 Apr 14th, this procedure is not needed now.__

    Import librarymbed-src_GR-PEACH_rev_c

    Please use mbed-src instead of this library.mbed-src supports GR-PEACH rev.C. mbed-srcライブラリをご利用ください。mbed-srcはGR-PEACH rev.Cに対応しています。
