实验环境 硬件:STM32板 (STM32F207 ) LCD12864 模块 (ST7565) USB转串口模块 TTL ST-Link V2 调试 软件:MDK Keil v5.12 PortHelper.exe 串口调试助手 实验目的 在嵌入式平台上生成QR Code,LCD显示 实验步骤:
/* Define to 1 if you have the `strdup' function. */ #define HAVE_STRDUP 0
/* Major version number */ #define MAJOR_VERSION 3 /* Micro version number */ #define MICRO_VERSION 0 /* Minor version number */ #define MINOR_VERSION 9
/* Define to the version of this package. */ #define PACKAGE_VERSION '3.9.0'
/* Version number of package */ //#define VERSION '3.9.0' #define LIBQRENCODE_VERSION '3.9.0'
/* Define to empty if `const' does not conform to ANSI C. */ /* #undef const */
/* Define to `__inline__' or `__inline' if that's what the C compiler calls it, or to nothing if 'inline' is not supported under any name. */ #ifndef __cplusplus /* #undef inline */ #endif
/* Define to 'static' if no test programs will be compiled. */ #define __STATIC #define WITH_TESTS 1
