I made the MK4 first and had an old FC that had wires all over so I redid the stack with new IS30 and F4 (HD) version with specific included cables to link the controller and flight unit. * The (UNO) circuit: Green TX White RX Red +5V Black Gnd * Uno RX is digital pin 10 (connect to TX of TF Mini) * Uno TX is digital pin 11 (connect to RX of TF Mini) */ #include #include 'TFMini.I have (had) two working quads with the DJI FPV setup, HD1 prebuilt from rotor riot and a GepRC MK4 pretty much same setup 5 inch. I am facing error when i connect 2 tf mini lidar to arduino the output gets stuck and it does not work. Dist_L = ser.read() #Byte3 Dist_H = ser.read() #Byte4īy multiplying Dist_H by 256, the binary data is shifted by 8 to the left (equivalent to ' = 9): Distance data is divided into two 8-bit packets, Dist_L (Byte3) - Lower 8bits and Dist_H (Byte4) - Higher 8bits. Once the header frame is read, the next two bytes, carrying distance data, could be read. They can be read and used to identify the start of the UART message. First two Bytes are frame header having a value of hex 0x59 (character 'Y'). The chart provided in the data-sheet gives us the 'breakdown' of 9-Byte UART message.

Even though RPi runs the same version of Python but there is a slight change in syntax as RPi does not accept data other than binary. To receive data, you need to forward the certain command to TFmini LiDAR (part of initialization process). The code can be divided into two parts, writing and receiving. Ser = serial.Serial('/dev/ttyUSB1',115200,timeout = 1) #Raspberry Pi The code can be divided into three parts:Īfter importing necessary header files, we estabilish connection to our TFmini LiDAR by stating its COM port, Baud-rate and connection timeout ser = serial.Serial('COM7',115200,timeout = 1) #PC Python programming for Raspberry Pi (optional).C/C++ programming for Arduino (optional).Reading schematics and connection diagrams.Hand tools like wire cutters and strippers.This instructable requires that you are familiar with the following: Communication Protocol: UART (Baud rate: 115200).

The built-in algorithm adapted to indoor and outdoor environments can guarantee an excellent ranging performance at a low cost and in a tiny volume, which highly expands the application fields and scenarios of LiDAR and lays a solid foundation for future “eyes” in the smart era. The product possesses three major advantages: low cost, tiny volume and low power consumption. The Benewake TFMINI Micro LIDAR Module has its unique optical, structural, and electronic designs.
