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!

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
C:\ti\msp430ware_3_80_04_05__win\msp430ware_3_80_04_05\examples\devices\MSP430FR2xx_4xx\MSP430FR231x_Code_Examples\C
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
