Arduino的：轻量级COM pression算法存储在EEPROM中的数据 [英] Arduino: Lightweight compression algorithm to store data in EEPROM

问题描述

我要存储大量数据，到我的Arduino与 ATmega168的 / ATmega328 的微控制器，但遗憾的是只有256＆NBSP; KB / 512＆NBSP; EEPROM存储KB。

I want to store a large amount of data onto my Arduino with a ATmega168/ATmega328 microcontroller, but unfortunately there's only 256 KB / 512 KB of EEPROM storage.

我的想法是利用一个COM pression算法来剥离下来的大小。但是好了，我的COM pression算法知识是相当低的，我的搜索​​准备好使用的库失败。

My idea is to make use of an compression algorithm to strip down the size. But well, my knowledge on compression algorithms is quite low and my search for ready-to-use libraries failed.

那么，有没有优化存储容量的好方法？

So, is there a good way to optimize the storage size?

推荐答案

您可能有一个看 LZO 算法，该算法被设计为轻量级。我不知道是否有实现的AVR系统，但它可能是一个你可以实现你自己。​​

You might have a look at the LZO algorithm, which is designed to be lightweight. I don't know whether there are any implementations for the AVR system, but it might be something you could implement yourself.

您可能是有关存储在EEPROM中的筹码，虽然可用的数量有所误导;根据数据表我有EEPROM大小：

You may be somewhat misinformed about the amount of storage available in EEPROM on your chip though; according to the datasheet I have the EEPROM sizes are:

ATmega48P：256
ATmega88P：512
ATmega168P：512
ATmega256P：1024

ATmega48P: 256
ATmega88P: 512
ATmega168P: 512
ATmega256P: 1024

请注意，这些值是的字节的，你提到你的问题不是KB。这不是由任何措施，一个shitload

Note that those values are in bytes, not KB as you mention in your question. This is not, by any measure, a "shitload".
