TMR-FC : Top Multi-Rotor Flight Controller

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

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

• Raspberry Pi

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

• Camera Module For Raspberry Pi

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"

  Segger J-Link EDU official website

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"
