试MSP432 launchpad有感 [复制链接]

昨天拿到TI的MSP432 launchpad实验板，随便搞了一个例程，无法使用，后来在TI官网下载一个有关MSP的
软件还是无法使用，再后来，更新了我的keil5 for ARM，可以运行TI的例程。
再再后来，我重新安装了CCS6.1软件，只选择了MSP430，勾选MSP432选项，这个默认是非选中的。
涛声依旧。

* MSP432 GPIO - Input Interrupt
*
* Description: This example demonstrates a very simple use case of the
* DriverLib GPIO APIs. P1.1 (which has a switch connected to it) is configured
* as an input with interrupts enabled and P1.0 (which has an LED connected)
* is configured as an output. When the switch is pressed, the LED output
* is toggled.

是通过TI store购买的吗？

如果是可以来这里晒单：
购买TI store MSP432P401R LaunchPad 晒单就送礼！

呵呵，TI送的，从这个例程可看出，现在的MSP432和过去的MSP430的
开发模式已经不同了，这个也和TM4C123G的固件库也有差别
看来我又得翻译MSP432的固件库函数了。

还有，MSP432已经不是单片机而是 ARM Cortex M4F内核了。
我发这个帖子可能对刚刚接触MSP432的坛友有点启发，
过去已经按照CCS6的坛友，如果不重新安装CCS6是不能
使用MSP432 launchpad实验板的。
