# WARNING
This application *__currently__* requires a patch to the Flipper exports to make it work as a FAP ...An issue has been raised: https://github.com/flipperdevices/flipperzero-firmware/issues/1747 ...It has been acknowledged on Discord, and expected to be resolved before FAP v1.0 is officially released.
WORKAROUND:
* EITHER: edit `firmware/targets/f7/api_symbols.csv` and:
* for `calloc` change:
* `Function,-,calloc,void*,"size_t, size_t"` to
* `Function,+,calloc,void*,"size_t, size_t"`
* for `LL_TIM_DeInit` change:
* `Function,-,LL_TIM_DeInit,ErrorStatus,TIM_TypeDef*` to
* `Function,+,LL_TIM_DeInit,ErrorStatus,TIM_TypeDef*`
* OR: paste these commands to edit the file inline
* `sed -i 's/\(Function,\)-\(,calloc,.*\)/\1+\2/' firmware/targets/f7/api_symbols.csv`
* `sed -i 's/\(Function,\)-\(,LL_TIM_DeInit,.*\)/\1+\2/' firmware/targets/f7/api_symbols.csv`
* THEN: Update the firmware on the Flipper
* `cd /path/to/flipper/`
* `./fbt flash_usb`

# FlipperZero PWM Demo (FAP)
This will allow you to configure a PWM timer {Frequency, Duty Cycle, Duty Scaling Curve} and attach it to a GPIO Pin.
You can currently select from:
* PB8 - Internal Speaker
* PB9 - Internal IR LED Array
* PB3 - External GPIO Pin
Internal LED, and Brightness scaling are currently not written.
