Feature cut for F411 and F722 boards

[DzikuVx]

This removed the support for following features on F411 and F722:

• Furious FPV 2.4GHz VTX
• Virtual Pitot
• PCA9685 servo driver
• SUMD RX protocol
• SUMH RX protocol
• XBUS RX protocol
• HOTT telemetry

Hi Pawel, in your message I read that support is dropped for the PCA9685 servo driver. Does this mean we can't use servo's in combination with an F722? Or can we still use a "PWM port" to control the servo(s).

This means exactly what was written: PCA9685 servo driver was removed from F722 and F411. Nothing more and nothing less

Alright, thank you for your response. I looked up the PCA9685 chip (probably should have done that before asking this question) and found an article describing the functionality. My conclusion is that we can still use Servo's on a F722 as long as we only use the available PWM (motor) output pins available on the FC. The PCA9685 is used to gain (16?) additional PWM outputs directed over I2C. Thanks!

Martin.. It means you can't use the 16 channel i2c servo expansion board. It's not needed for what most of us are using the older flight controllers for. It was more than likely removed to free up memory to prevent issues. I'd rather reduce some features than risk a crash.
