FRK-RX62N (16) printf (4) KPIT GNURX Newlib: SYSLAB blog

[画像]
前回の続き「KPIT GNURX で printf を使う」
副題として、［SYSLAB blog 読者限定公開第二弾 GNURX printf の使い方 Newlib 編］
前回同様中身は無いに等しい。 Renesas のサンプルと WINARM のサンプルをコピーするだけだ。

それでは始めよう。
１．KPIT GNURX で新規プロジェクトを作成する。
２．前回作成した hardware_setup.c を新規プロジェクトの中にコピーする。
３．main を新規プロジェクトの中にコピーする。
４．ソースの中の stdint.h をローカルから読み込むようにする。
　　#include "stdint.h"
　　もちろん stdint.h はプロジェクトディレクトリにコピーしておく。そうでなければ stdint.h をinclude しないようにして uint32_t などを unsigned int と書き直せばよい。
５．serial_printf.c をプロジェクトにコピーする。
