TI中文支持网麻烦提供一个FR4133的串口通讯程序呢，谢谢，ti给的两个都不管用，想在32768kz下，9600通讯就行，低功耗3模式
ti的两个都没有接收到
同时感觉不是低功耗的例子，
以前的其他430通讯程序不管用了
谢谢
xiaolong wei：
我自己写了个试了试也不行：
UCA0CTLW0 =0X20
UCA0BR0=0X3
UCA0MCTLW = 0X9200
我直接写入 txbuf 一个数据 pc没有接到
pc发 单片机也没有收到

不好意思
刚才试了 msp430fr413x_euscia0_uart_01.c
这个能通讯的，但是耗电量太大了 20ua以上！！
怎么才能低功耗呢
是不是只有时钟降低？
麻烦帮忙给个低功耗的例子程序，谢谢

问题是
关于串口的两个时钟源 UCLK MODCLK 究竟是啥
ACLK怎么才能用上，32768的晶体频率怎么用于串口通讯
是不是不能用？？？?？

楼主你好。你的问题解决了吗？
我看了这个例程，里面用的就是ACLK = 32768Hz，不过是用的片上的RC振荡器。MCLK 和SMCLK 配置为了8MHz。

楼主你的那个可以正常通信的大电量c程序在哪找的啊？

见附件。
TI 官网下载 MSP430Ware 里面包含 所有的示例代码。

你好，
MSP430FR4133的寄存器和MSP43F,G都略有区别。
你可以下载MSP430WARE，里面有千千万万的例程供你参考。
我把相应例程粘贴出来供你参考。
