# CUSTOM FlightController-H743
The repo contains flight controller target files, PCB Gerber files, and the schematic.
## NOTE the spi lines length has a mismach that needs to be corrected
## FC notes
Nickel-H473 is inspired from MAMBAH743_V4 FC
However custom pin can be used unless their usage is not compromised , STM programmer IDE can be a great help in case assigning pins.
## FIRMWARE SETUP
ARDUPILOT : **https://github.com/ArduPilot/ardupilot**
Target Files :`libraries/AP_HAL_ChibiOS/hwdef/`
Environment setup : https://ardupilot.org/dev/docs/building-the-code.html
Build cmd :
```bash
./waf distclean
./Tools/scripts/build_bootloaders.py Nickel407 # Builds bootloader (outputs to Tools/bootloaders/)
./waf configure --board FlyingMoon407
./waf plane
```
bin/hex file are stored in build directory
It is recommended to go through ardupilot documentation First
## Target Files
There are two primary target files ` hwdef-bl.dat (responsible for building bootloader)
hwdef.dat (for main firmware)`
Checkout this HW files for reference example : https://github.com/ArduPilot/ardupilot/tree/master/libraries/AP_HAL_ChibiOS/hwdef/fmuv3
## Schematic & PCB
Check schematic folder
The pcb is 2 layer 47 * 60 mm

## STM programmer IDE
- Pin Selection :
- For clocks use 8,16,24,32 MHz crystal (odd multiples causes issues)
