| Mar 16, 2020 at 7:01 | comment | added | user2268171 | How come Arduino compiles the code fine? I tested with the long switch statement of 16384 cases and it says it uses only 1000 bytes. I'll edit my question to include this. | |

| Mar 15, 2020 at 23:09 | comment | added | Majenko | What is it you're doing that needs such a huge lookup table? | |
| Mar 15, 2020 at 23:07 | comment | added | user2268171 | I might be able to compress the array in some way. There's a lot of duplicates in the array so the amount of unique values is a lot less than 16384. | |
