RVB2601开发板到手有一段时间了，断断续续的测试集成开发环境的使用，这期间发现了很多的问题。经过摸索，在原先的演示程序的基础上修改了OLed的基本驱动，添加了可以打印汉字及英文字符串的一系列函数。将原先的测试需要操作系统的去除，直接裸奔，实现了，oled显示字符串，及定时器，按键测试。板子上面的 KEY1 压下，oled 显示KEY1。KEY2按下oled显示KEY2。
1，先说说CDK的一些问题及应对解决方法。CDK编译当前工程后，不能 点击 Debug 菜单下面的 Start/Stop Debug正确运行，一定要手动点击 Flash 菜单 下面Download将编译通过的程序写入RVB2601，然后，再点击Debug菜单下面 Start/Stop Debug的启动程序这样才能正确进入调试 。
2，如果，停止，调试后，无法再次进入调试，无论点击 Start/Stop Debug 还是 Start/Stop Debug Without Dowmload 都是无法正确调试的。必须再次Flash菜单再次Download才能再次进入调试 3， vsprintf 函数有问题，在其他开发环境正确的程序CDK编译出结果是不正确的，现象是 转换英文字符串，没有错误，转换汉字字符正确的 应该转换出2个BYTES，实际出来占用3BYTES。我的解决方案是直接调整指针。具体，可以参看我的oled 的驱动函数。
