My project involves developing a compact radar system for vital sign tracking, utilizing the TMC5272 motor control technology to ensure precise radar movement for continuous and uninterrupted measurements. To enhance portability, I plan to power the motor using a battery. The first step is to conduct a simple experiment to verify whether the stepper motor can operate reliably with a 9V battery.
Make sure to set the resistor to 15k and amp to .4 in the current setting
For this experiment , I use velocity mode with the setting below to move the stepper motor
Next Step
The next step is to use the Raspberry Pi 5 to communicate with the TMC5272 and remotely control the motor.
