ロボット用の FRAM 用のドライバーを作成していますが、突然次のエラーが発生し始めました。

何が原因なのかはわかりませんが、コード内に複数の定義を見つけることができませんでした。ヘッダーファイルは次のとおりです。

最後に、テストベンチ ファイルは次のとおりです。
#include "FRAM_driver.h"
#define FRAM_SCL_PIN 28
#define FRAM_SDA_PIN 29
static FRAM_driver_type fram_obj;
int main() {
const unsigned char* data = 2;
FRAM_driver_setup(&fram_obj, FRAM_SCL_PIN, FRAM_SDA_PIN, 0);
FRAM_log_data(data , &fram_obj);
FRAM_read_data(&fram_obj);
}
どんな助けでも大歓迎です。また、Propeller マイクロコントローラ用に simpleIDE と simpletools ライブラリを使用しています。
