To the left is a picture of the talon SRX (our current talon model). The SRX has 4 main wires coming out of its ends: one red, one black, one white, and one green. The red and black will be used for inputting the necessary power to run the talon. The green and white will be used for sending power directly to the motor. To connect these best, it's recommended that you fit the end of each wire with an Anderson powerpole connector. Lastly, there are two smaller wires, which are green and yellow and extrude near the black power wire. These wires will be responsible for receiving pwm signal inputs from the raspberrypi, which will alternate the speed of the motors. To read up about pwm signals click here.
After you've completed all the wiring and plugged the pwm signal wire into your raspberrypi's pins, you are ready for calibration. To begin the process, first clone this repository, which includes code for calibrating and sending pwm signals to the talon. After you've cloned the repository, access it in terminal and run the calibration code. If you are having trouble finding the calibration button referenced in the code, it is the white box pictured in the photo to the top left. Once the talons have blinked green and are fully calibrated, run the Servo_PWM code. This code will allow you to run the motor in reverse, forwards, and in neutral.
To the left are some helpful blink codes that you may come across, while working with the talons. They will tell you if the talons are functioning properly, calibrated correctly, or even broken.
