Question

我想在Linux下为AVR MCU使用一个简单的汇编程序编译器。我通常不喜欢MCU的完整开发环境（比如AtmelStudio胜利）。例如：我在Linux下编写了一个小型C程序通过并行端口将字节发送到AVR芯片的闪存和eeprom存储器在ISP模式下。现在我想在Linux下找到一个简单的汇编程序我不会像C编译器或Atmelstudio那样喜欢任何解决方法在Linux下的win或虚拟机下。现在我在新鲜的lubuntu下尝试了avra。

所以看起来Intel Hex输出是在没有任何错误的情况下生成的。我不知道这只是与PRAGMA指令有关的警告，我可以使用这个编译器适用于任何更复杂的源码，或者我必须找到其他的 Linux下的AVR mcu汇编程序？以下是设备def文件中的一些有问题的行：＆＃34; /usr/share/avra/tn45def.inc"。：

我尝试了解AVRFREAKS链接中的内容： http://www.avrfreaks.net/forum/problems-attiny261-v2-or-avra-130-osx-update 看起来Atmel的包含文件可能是编译器可以理解的更新版本。什么可以是Linux下的简单AVR汇编程序？

解决方案是gavrasm（最新和开源，工作正常）。

avra汇编程序 - pragma？
