| Summary | 0000053: Add Important Variables Into Structs And Refactor Placement Of Existing Ones | |||||||||||
| Description |
Some variables are in places that they do not belong. Many variables don't exist yet. I should go through them in conjunction with the datalog thread and tidy them up a bunch. If the other issue turns out to be a goer and the format changes, it would be a good opportunity to place them in order into separate memory regions such that a direct copy from RAM Is possible with minimal CPU overhead. |

To clarify what I meant by separate RAM region : Set aside a piece of global RAM and pre init it with header data. After the header data block would be the various structs placed sequentially such that when a datalog needs to be sent it is a single memcpy() call of maximal efficiency only. | header | struct 1 | struct 2 | struct n -1 | struct n | normal RAM .... then the memcpy call can just take the configured length and it is single stage with no excessive ifs etc. Once it is in the serial buffer a normal checksum and send call can be made. |
