TMR-FC : Top Multi-Rotor Flight Controller

TMR-6A

Descriptions

  • TMR-FC is built for my graduation project, It's designed to control a multi-rotor copter for research,

    It's supposed to not for sale, but if you are interested, you can build it by your self, I can provide

    a empty PCB to you.

  • V1.0

TMRFC-T TMRFC-B

  • V2.0 ( Work stand alone or became a daughter board of Raspberry Pi with camera board for flow application )

TMRFC-PI

  • Raspberry Pi

Will use OpenCV, ROS, MAVLink ... etc
Offical Website : http://www.raspberrypi.org/

TMRFC-RPI

  • Camera Module For Raspberry Pi

PI-CAM

Hardware Features

  • CPU :

    V1.0
    
        STM32f405RG
        
    V2.0
    
        STM32f407VG
    
  • Sensors :

    V1.0
    
        I2C : MPU6050, HMC5883, MS5611
        
    V2.0
    
        I2C : HMC5983, MPL3115A2 ( or MS5611 )
        SPI : MPU6000, *LSM303DLM, *L3G4200D
        ADC : *ADXRS652 x 3
        
        * Marked are optional item. In some applications, all sensors can be sharing
          to Raspberry Pi for applications to use.
    
  • Features :

    V1.0
    
        12 channels PWM output, one PPM input and one Futaba S.BUS input,
        Built-in 10 DOF, 5 LEDs ( controlled by PCA9533/9536), GPS port ( UART / I2C),
        Auxiliary SPI and  GPIO, RF port (APC230 or BT), LiPo Voltage measure via ADC,
        Beeper for tone alarm, SWD port, SONAR, USB VCP and MSC, Micro SD ( can be read via USB),
        Light Bar LED control, Internal FLASH EEPROM emulation using sector 1, 2 and 3 ( 16KB x 3 ),
        RTC ( power keep by 3V CR1220 ), USB OTG,
        ....... etc
    
    V2.0
    
        + CAN transceiver IC ( TJA1050 or MAX3051 )
        
        This version is under construction. I think that using Raspberry Pi to as a brain to control
        a copter is a good ideas, but I do not have money to do so, :( , If you want 
        co-work with me or any idea on V2.0, please email me, or you want to donate to TMR V2.0.

  • Stress Test VB scripts :

    Auto re-boot loop test, tone alarm loop test, ..... etc
    
  • Support PX4 Qupgrade tool :

Firmware update steps

Update bootloader

  • Optinn 1 : Using "dfu-util" ( Recommend )

     sudo dfu-util -a 0 -d 0x0483:0xdf11 --dfuse-address 0x08000000 -D tmrfc_bl.bin
    
  • Optinn 2 : Using "Segger J-Link"

Update OS image

  • Optinn 1 : Using "dfu-util"

     sudo dfu-util -a 0 -d 0x0483:0xdf11 --dfuse-address 0x08004000 -D tmrfc-v1_default.bin
    
  • Option 2 : Using "QUpgrade" ( Recommend )

     Note :  To using "QUpgrade" if you have " tmrfc_bl.bin" been pre-flashed !!! 
    
     1. Get the tool :  (https://pixhawk.ethz.ch/px4/downloads)<br />
     2. Open "QUpgrade" tool
     3. Select "Advanced"
     4. Select your "tmrfc-v1_default.px4"
     5. Click "Flash"
     6. Connect your TMRFC board via USB, OR click "RESET" key on TMRFC board
    
  • Optinn 3 : Using "Segger J-Link"
