Generally, yes you can store data in the OTP but keep in mind that OTP stands for One Time Programmable, thus you can’t erase and re-write the OTP multiple times, but you can only flip the bits that are still set to 0 and turn them to 1. This means that if you store your data, you cannot change them in the specific addresses.
嗨，马克，
我很好，谢谢。希望你做得很好了。也感谢你的问题。
什么样的数据，你想保存？
DA14585不包括片上SPI闪存 - 所述DA14586包括闪存。
但是，您可以使用外部SPI闪存和存储数据。你有没有在你的设计中这个选项？

嗨PM_Dialog，
我想存储的数据大约是1Kbytes。如果我去DA14586在我的设计，我可以使用内置闪光灯来存储数据。是否有任何代码来读/写DA14586内部闪存的数据？
问候，

嗨，马克，
SDK的spi_flash例如可以作为参考。这个例子是在6.0.14.1114 \项目\ target_apps \ peripheral_examples \ SPI \ spi_flash \ Keil_5 SDK路径，应该是建立DA14586配置。在user_periph_setup.h / .C，你会发现GPIO配置应该用于DA14586内部闪存，因为它是标准的引脚。对于使用闪光灯进行交互，应使用SPI闪存（spi_flash.c）驱动程序。
谢谢，PM_Dialog
