利用Eclipse IDE for C/C++ Developers和GNU Tools ARM Embedded編譯器

ID:77367 · 發表于 2015-4-19 00:57

工作環境說明:

1.硬件平臺: DX開發板主板 + DX103核心板

2.硬件平臺: Eclipse IDE for C/C++ Developers + GNU Tools ARM Embedded
  (1) IDE: Eclipse IDE for C/C++ Developers
  (2) 編譯器: GNU Tools ARM Embedded編譯器，支持STM32F407最新的HAL驅動庫

用Eclipse IDE for C/C++ Developers新建一個C工程模板，主函數代碼如下：

// STM32F4 led blink sample (trace via ITM).
//
// In debug configurations, demonstrate how to print a greeting message
// on the trace device. In release configurations the message is
// simply discarded.
//
// To demonstrate POSIX retargetting, reroute the STDOUT a.n.d STDERR to the
// trace device a.n.d display messages on both of them.
//
// Then demonstrates how to blink a led with 1Hz, using a
// continuous loop a.n.d SysTick delays.
//
// On DEBUG, the uptime in seconds is also displayed on the trace device.
//
// Trace support is enabled by adding the TRACE macro definition.
// By default the trace messages are forwarded to the ITM output,
// but can be rerouted to any device o.r completely suppressed, by
// changing the definitions required in system/src/diag/trace_impl.c
// (currently OS_USE_TRACE_ITM, OS_USE_TRACE_SEMIHOSTING_DEBUG/_STDOUT).
