OpenNaze Naze32

#OpenNaze/Naze32 Tau Labs now offers basic support for the OpenNaze rev. 4 (Naze32 compatible). More features will be implemented in future. ##Supported Features

• PWM and PPM receivers
• PWM outputs on motor pins and receiver pins
• GCS telemetry on USB/UART1
• SyncPWM and FastPWM (Oneshot)
• Autotune
• UART on receiver pins
• Serial receivers
• ADC

##Currently Unsupported

• GCS flashing
• Barometer
• Magnetometer

##GCS Connection GCS can be connected using the USB port. The Naze uses an SILabs CP2102 USB->UART chip to connect the USB port to UART1, which presents as a virtual serial port on the host OS. For Windows users this will require a driver. Linux users will need to be in the dialout group, acomplished using this command (change user to your username):

usermod -a -G dialout user

##Flashing ###Entering Bootloader Mode ####Tau Labs Already On Board Connect the board to GCS, go to the Firmware tab and click halt. The board will enter bootloader mode (all three LEDs on solid). See the Flashing Firmware instructions below. ####Initial Tau Labs Flash To flash Tau Labs initially you will need to put it into bootloader mode by another method, either by shorting the "Boot" pads on startup, or sending the character "R" via serial if Baseflight is loaded (on *nix echo -n "R" > /dev/ttyUSB0). ###Flashing Firmware ####Building firmware from source

> make fw_naze32

####Flash firmware and erase settings:

> ./tools/stm32flash/stm32flash -w ./build/fw_naze32/fw_naze32.tlfw -b 115200 -v -g 0x0 /dev/ttyUSB0

Note:

• You will need stm32flash in your tools directory, this can be done using the command make stm32flash_install.
• Replace /dev/ttyUSB0 with the appropriate port, on Windows this will be COMn where n is a number.
