正在编写STM32_EASY库

虽然STM32的官方库已经做得非常EASY了，但是对于经常手抽的小白们来说，还是要输入太多的字符，所以，我仿照了Arduino的格式做了一个库叫做：STM32_EASY!

还没做完，做个预览撒：

:o有啥功能？

lyili 发表于 2013-9-23 22:05:30

好好，支持完善～

这个要支持。。。对于刚开始使用STM32的吾等小白来说。。。STM32太复杂了。。。。

likunyang 发表于 2013-9-24 19:16:46

嗯不错我也不喜欢STM32的库，函数名太复杂了

不过做STM32 Arduino适配的有很多

例如leaflabs等，建议楼主参考一下，别做太多无用功

FoieDEEEE_仲敬 发表于 2013-9-24 20:41:04

谢谢支持，我主要是做关于液晶屏等外设操作的函数库
