自从使用STM32芯以后,就对此芯非常关注,从经典STM32F1XX到现在的STM32F4XX都给我带来了不秒的满足感!记得以前有很长一段时间开机第一就会打开ST官方论坛,寻找各种由此芯创造的新事物。邮箱中也经常会收到一新产品展示的推送,对于求知欲非常强的我来说,这可真是如鱼得水般的兴奋。好了,这里首先非常感谢ST中国社区版主沐紫,让我有429这款芯片实战体现机会。也对在过去一月中未能及时发贴而感到非常抱歉。 首先先介绍这款《STM32F429套件》硬件做一个简单的介绍。 ![]() 图1 ![]() 图2 4 l Q& ]+ ]# R, w/ y$ v STM32F429ZIT6 microcontroller featuring 2 MB of Flash memory, 256 KB of RAM in ) j0 v& I4 d% G& ~- xan LQFP144 package " S1 r. |!
