WeFax rx ext app (#2566)
* wf3
* Ookbrute (#2354)
* Revert "Ookbrute (#2354)"
This reverts commit abb8143eec.
* fix
* test edition
* re enable ble
* re enable ert
* steal amfm stuff
* something happens
* save bmp on start btn
* kinda works
* exit crash fixed
* redline, remove some hardcoded
* removed cpu killer red line, and some fixes
* simplify #1
* seems ok. time to improve
* added hidden freq offset to receiver model, so wefax can be set to the "correct" freq without users needs to substract 300 hz
* badly implemented sync detection, and disabled it.
* fix for fix
* fixes
* fix offset to real life off
* no line on freq enter
* fixes

TODOS LATER:
|
||||
- add load data from wav file (maybe to a separate app, not this)
|
||||
- AGC?!?
|
||||
- fix and enable sync detection
|
||||
- auto start / stop bmp save on each image
