# flipperzero-chronometer
⏱️⏱️ A chronometer application for the Flipper Zero ⏱️⏱️
This chronometer is accurate to the millisecond. **TIM2** internal timer of the **STM32** MCU is used to generate a 64 MHz clock signal. This signal is used to count elapsed time.
## Gallery
**Note:** Chronometer stops after 99 hours, 59 minutes and 59 seconds
## Build the program
Assuming the toolchain is already installed, copy **flipper_chronometer** directory to **applications_user**
Plug your **Flipper Zero** and build the chronometer:
```
./fbt launch_app APPSRC=applications_user/flipper_chronometer
```
The program will automatically be launched after compilation
**Button assignments**:
button | function
------------- | -------------
**Ok** *[short press]* | Start/stop the chronometer
**Ok** *[long press]* | Reset the chronometer
**Back** *[long press]* | Exit
If you don't want to build this application, just simply copy **flipper_chronometer.fap** on your **Flipper Zero**
Build has been made with official toolchain, **API Mismatch** error may appear if you are using custom firmware. You can bypass this error but the program may crash.
