JHEMCU F4-openlogger high-speed serial port black box

Many pilots have become accustomed to using various black box data analysis software to adjust PID and filter parameters.
At present, many flight controllers do not have large-capacity black boxes, and the onboard ones are only 8-32MB, especially for
many AIOs because of space constraints. It is impossible to place a large-capacity black box, so the open source F4-openlogger
high-speed serial port black box appeared.

Open source address: https://github.com/d-ronin/openlager

Power supply: +5V
Interface: UART

Prepare your own Micro SD card. Connect the F4-openlogger module and the flight controller correctly. Refer to the wiring diagram
for the connection method. The BetaFlight ground station sets the port function of the external black box. Here, UART7 is used as a
demonstration, and Blackbox logging is selected, and the baud rate is 2000000. Enter the black box interface, select Serial Port, 2KHZ,
GYRO_SCALED, (Black logging rate/mode are selected according to their actual needs). After each setting is completed, click the
Save and Restart button.

Indicator meaning:

Red light: power is normal
Blue light off: SD card detected, ready to work
Blue light flashes slowly: no SD card
Blue light flashes quickly: it will only appear after the remote control is unlocked, and the black box normally writes the data returned
by the flight controller

Reading of black box files:

Export the LOG000 file of the SD card to the computer (the file serial number is automatically incremented by 1 each time the power
is turned on), where the CFG file is the black box configuration file, which can be exported. LOG000 is the log file generated after
unlocking this time. It can be opened with Betaflight Blackbox Explorer software and the recorded flight data can be seen.
