## Servo update rate
If you want a higher servo update rate (because of digital servos), it is probably better to set the scheduler loop rate to the frequency you want, and enable ONESHOT (assuming you have a BLHeli ESC):
```js
SCHED_LOOP_RATE=100 # As above.
SERVO_BLH_OTYPE=1 # For ONESHOT.
```
With no BLHeli ESCs, change your `SERVO_RATE`:
```js
SERVO_RATE=100
```

# DJI FPV configuration
If you're using the DJI FPV system, here's the relevant configuration you need to set:
1. Set `OSD_TYPE=3`.
2. Set `SERIALn_PROTOCOL=33 SERIALn_BAUD=115 SERIALn_OPTIONS=0` (DJI FPV).
3. Create a text file called `naco.txt` on the SD card of the Air Unit with the text `1` in it [to unlock full power](https://oscarliang.com/dji-fpv-system-fcc-700mw/).
4. Create a text file called `naco_pwr.txt` on the SD card of the goggles with the text `pwr_2` in it [to unlock more full power](https://oscarliang.com/dji-fpv-system-1200mw-output/).
5. Set "Custom OSD" to "on" in the goggles menu.
6. Arrange your OSD elements how you like them.
That's it!

## DJI FPV configuration
If you got some DJI goggles, here's the relevant configuration you need to make:
1. Set `OSD_TYPE=3`.
2. Set `SERIALn_PROTOCOL=33 SERIALn_BAUD=115 SERIALn_OPTIONS=0` (DJI FPV).

## DMA on the Matek F405-Wing
If you want to get DMA on UART3 of the Matek F405-Wing FC (or, more relatedly, the Racerstar F405, because UART1 is Bluetooth there), you can open `libraries/AP_HAL_ChibiOS/hwdef/MatekF405-Wing/hwdef.dat` and comment out line 92ish, where PA15 is defined.
@ -24,6 +11,6 @@ That will enable DMA on UART3, at the expense of disabling the LED pad.
