Hello all,
如題，如何修改MSP430F5529 跑 TI-RTOS的時鐘(clock)從內部晶振改成外部晶振呢?
謝謝。
请看一下相关工程师的回复：
1. For setting up the device, ignore TI-RTOS. That is for running specific tasks once the device is setup. Use this code example for setting up a LF xtal: https://dev.ti.com/tirex/explore/node?node=A__ALDSyPuzciqGUqasjmxBaQ__msp430ware__IOGqZri__LATEST
Keep in mind, your setup may vary from what's in the code depending on your hardware setup. In particular the load capacitance needed for the device. If you have external load caps, then you shouldn't enable the internal ones available for this device. For details on external load caps and balancing them for your crystal please see section 2.1 of the following app note: MSP 32-kHz Oscillators.
The while loop checking the DCO flags is what ensure the xtal is stable until it moves on. You can enable the interrupts associated with the xtals to be able to get informed if xtal failed and switched to REFO.
My advice is to setup the device first w/o TI-RTOS integration and make sure you got the device operating how you want it, then integrate that setup in your TI-RTOS project.
2. Of course, Ti-RTOS expects a particular frequency, though you should be able to change it. I imagine you need to dive into the configuration file:
Hi Yale,
能否順便請教一下UART BSL，手上有一個MSP430F5529 Rev E的，這版本再進入UART BSL好像有問題，請問該如何解決?
謝謝
