STM32F411CEU6 Board Firmware

Responsibility and resource

This is the unofficial target for INAV( Original source: https://github.com/iNavFlight/inav). Provides support for flight control boards that do not have official INAV support for the STM32F411CEU6 board. Whether or not to use this firmware is the user's responsibility and is free to do so. INAV developer link : https://github.com/iNavFlight/inav/tree/master/docs/development You can find all the details for firmware development here.

STM32F411CEU6 INAV Firmware

STM32F411CEU6 Board Firmware First, let's connect the board and the computer.

Download INAV Configurator

https://github.com/iNavFlight/inav-configurator/releases

Windows

Download Configurator for Windows platform (win32 or win64 is present) Extract ZIP archive Run INAV Configurator app from unpacked folder Configurator is not signed, so you have to allow Windows to run untrusted application. There might be a monit for it during first run

Install DFU Drivers (DFU mode)

ImpulseRC Driver Fixer

https://impulserc.blob.core.windows.net/utilities/ImpulseRC_Driver_Fixer.exe

• Start ImpluseRC Driver Fixer
• Connect the FC USB to the PC While holding the boot button in. (DO NOT power on FC via external 5V or Vbat)
• The ImpulseRC Driver Fixer should then see and load the proper driver
• Start INAV configurator
• Connect the FC USB to the PC while holding the boot button in.
• INAV configurator should show it’s connected in DFU mode in the top right corner (DO NOT click the CONNECT button)
• Choose the latest hex file for your FC and then “Load Firmware local”. Once loaded, click “Flash Firmware”.

Calibration for ESC

Instructions for setting throttle calibration for ESC high and low signal input:

1. Connect the ESC with the motor, connect the signal lead to the board according to the pin and motor port according to the diagram. You should do this for all of the motors you are going to use.
2. Open the INAV Configurator and connect to the flight control hub.
3. Adjust the gyroscope / accelerometer and magnometer calibration settings.
4. Turn on the remote control and enable the receiver protocol in the Receiver section.
5. Go to the Output field and set the ESC output protocol according to you. We describe the setup for the STANDARD protocol. 6.To calibrate ESCs, make sure the propellers are off, flick on the “I understand” toggle, raise Master to full value, and plug in your battery.
6. The ESCs will go through their tones.
7. When the double beeping sound is heard (the highest point of the throttle is confirmed), move the throttle to the lowest point.
8. ESC calibration is considered done when three beeps mean OK.
9. Now unplug, plug in again, and raise Master very slowly until the motors are spinning comfortably.

SBUS Signal Inverter

The inverter is easy to make, only requires 2 resistors (10K ohm and 4.7K ohm), 1 transistor (BC547b), and one servo cable. These are all very cheap and easy to find.
