UART Mapping
|
||
|
|
============
|
||
|
|
|
||
|
|
- SERIAL0 -> console (primary mavlink, usually USB)
|
||
|
|
- SERIAL1 -> USART2 (telem1, DMA-enabled)
|
||
|
|
- SERIAL2 -> USART3 (Telem2, DMA-enabled)
|
||
|
|
- SERIAL3 -> UART4 (GPS1)
|
||
|
|
- SERIAL4 -> UART8 (GPS2, DMA-enabled)
|
||
|
|
- SERIAL5 -> UART7 (USER)
|
||

RC Input
|
||
|
|
--------
|
||
|
|
|
||
|
|
All compatible RC protocols can be decoded by attaching the Receiver's output to the SBUS input pin next to the Servo/Output VCC input connector. Note that some protocols such as CRSF or FPort including telemetry, require connection to, and setup of, one of the UARTs instead of this pin.
|
||
|
|
|
||
|
|
PWM Output
|
||
|
|
----------
|
||
|
|
|
||
|
|
The PixPilot-V3 supports up to 14 PWM outputs. First first 8 outputs (labelled S1 to S8) are controlled by a dedicated STM32F103 IO controller. These 8
|
||
|
|
outputs support all PWM output formats, but not DShot.
|
||
|
|
|
||
|
|
The remaining 6 outputs (labelled AUX1 to AUX6) are the "auxiliary"
|
||
|
|
outputs. These are directly attached to the STM32F427 and support all
|
||
|
|
PWM protocols as well as DShot.
|
||
|
|
|
||
|
|
All 14 PWM outputs have GND on the top row, 5V on the middle row and
|
||
|
|
signal on the bottom row.
|
||
|
|
|
||
|
|
The 8 main PWM outputs are in 3 groups:
|
||
|
|
|
||
|
|
- PWM 1 and 2 in group1
|
||
|
|
- PWM 3 and 4 in group2
|
||
|
|
- PWM 5, 6, 7 and 8 in group3
|
||
|
|
|
||
|
|
The 6 auxiliary PWM outputs are in 2 groups:
|
||
|
|
|
||
|
|
- PWM 1, 2, 3 and 4 in group1
|
||
|
|
- PWM 5 and 6 in group2
|
||
|
|
|
||
|
|
Channels within the same group need to use the same output rate. If
|
||
|
|
any channel in a group uses DShot then all channels in the group need
|
||
|
|
to use DShot.
|
||
|
|
|
||
|
|
Battery Monitor Settings
|
||
|
|
========================
|
||
|
|
|
||
|
|
These should already be set by default. However, if lost or changed:
|
||
|
|
|
||
|
|
Enable Battery monitor with these parameter settings :
|
||
|
|
|
||
|
|
:ref:`BATT_MONITOR<BATT_MONITOR>` =4
|
||
|
|
|
||
|
|
Then reboot.

||
|
|

||
|

|
||
|

|
||
|
|
|
||
|
|
DroneCAN capability
|
||
|
|
===================
|
||
|
|
There are 2 CAN ports which allow connecting two independant CAN bus outputs. Each of these can have multiple CAN peripheral devices connected.
|
||
|
|
|
||
|
