PX4-OmnibusF4v3 code ( modify from PX4-OmnibusF4SD )

PX4 Autopilot

Hi friends,

I’m new PX4 user of Taiwan, and try to make porting for OmnibusF4v3 base on OmnibusF4SD’s code last few months. It is seem work, even it’s not perfect. But, I hope share it to you.

If you have any problem, let me know please. I’ll try to solve these troubles, under my bad english.

Please reference to following issues:

RC-in support PPM only.

serial ports

TEL1 : /dev/ttyS0 → UART1 of STM32F4

RC_PORT : /dev/ttyS1 (No show in QGC and H/W.)

TEL2 : /edv/ttyS2 → USART4 of STM32F4

URT6 : /dev/ttyS3 → UASRT6 of STM32F4 (Needs inverter of H/W, if you want to use it. )

Hey, I’ve Omnibus F4v3 (non Pro) with F4SD PX4 firmware and it works when tested on the ground.
What are the differences in your firmware?
The only thing missing for me is PWM 5 & 6.

  1. Add AK8963 Driver

It has compass built in or its for external?

Your firmware doesn’t support SBUS?

Hi,

My answer as the following.

What are the differences in your firmware? → The circuit diagram was differences between F4v3 and F4SD.

The only thing missing for me is PWM 5 & 6. → PX4 has not support PWM 5 & 6 under this version.

It has compass built in or its for external? → You can add AK8963 by external I2C bus.

Your firmware doesn’t support SBUS? → You must disable UART6, if you want to use SBUS.

Could you share your file timer_config.cpp?
