# Betaflight 4.5 `USE_` defines This is simply the search results for `USE_` statements in betaflight code. Some may not be viable custom defines. In fact, many do indeed break (error) cloud-building. To use them as custom define, exclude the `USE_` and type the remainder of the text. *_updated May 9 2024_ against master at commit `d1ffa46aa` ``` USE_64BIT_TIME USE_ABSOLUTE_CONTROL USE_ACC
