v3.2 seems slow

Post by Macumazahn »

I updated my DM42 from the original shipping firmware to new version 3.2, and the result is a slowdown of about 7%.
Wondering if I can go back to v3.0? Only v3.1 is visible on the download page for earlier versions.

I guess the slowdown is due to the C/C++ compiler optimization level being turned down a notch for the v3.2 firmware to work around the problem of the calculator hanging when running some user programs.

I speculate that there might be some issue in the source code that only manifests as a problem at the higher optimization level, but very few people have seen the source code (apart from the imported Free42 code).
