MSP430FR2311 燒錄 & 功耗設計問題協助

Other Parts Discussed in Thread: MSP430FR2311, MSP-GANG

1: MSP430FR2311带电烧写不能自启动,只能重新上电或者通过SBW发送reset(但这个也不稳定),这个是否还有解决方案?

我要自制一个固件量产烧录工具这方面也请给予指导;或是提供相關文件檔.

2,目前功耗离理论差距较大,需要指导低功耗的相关配置,如2311是否有LPM3.5模式,GPIO的内部结构图能否给出,时钟DCO.MCK,SMCK的相关配置。

謝謝!

  • 1、楼主现在用的什么烧写工具?相关电路是怎么样的?官网的烧写工具,在烧写完都是自动复位的。

    2、推荐用官网的批量烧写工具msp-gang

    3、楼主说的功耗是单独mcu的功耗吗,还是带外围电路?mcu的功耗和具体的配置及代码有关,建议提供下现在的源代码。

    4、这个mcu偶LPM3.5的。GPID的结构以及DCO.MCK,SMCK可以参考数据手册

  • 谢谢楼上的详细解答!

    补充一下

    MSP430FR2311是有LPM3.5的,可以参考数据手册 www.ti.com/.../msp430fr2311.pdf

    • Optimized Low-Power Modes (at 3 V)
    – Active Mode: 126 µA/MHz
    – Standby: Real-Time Clock (RTC) Counter
    (LPM3.5 With 32768-Hz Crystal): 0.71 µA
    – Shutdown (LPM4.5): 32 nA Without SVS

    关于LPM,我们是有相关例程的,您可以参考一下

    您可以下载MSPWARE获取,默认路径为

    msp430fr231x_LPM3_01.c Enters LPM3 with ACLK = XT1CLK = 32768Hz.
    msp430fr231x_LPM3_02.c Configure MCLK and SMCLK up and down to adapt LPM3.
    msp430fr231x_lpm3_5_01.c LPM3.5, device enter LPM3.5 and toggles P1.0 with RTC interrupt handling every 1s
    msp430fr231x_lpm4_5_01.c LPM4.5, Device enters LPM4.5 waiting for a port interrupt on P1.2
    msp430fr231x_lpm4_5_02.c LPM4.5, Device enters LPM4.5 waiting for a port interrupt on P1.2 with SVS disabled
