# Pico Serial Motor Control Integration
|
|
|
|
This project enables a Raspberry Pi Pico to be controlled via serial commands from a TypeScript backend. The Pico firmware parses commands received over serial and controls a stepper motor accordingly, while also sending log/status messages back.
|
|
|
|
## Serial Commands Supported
|
|
- `STEP <steps> <direction>`: Move the motor by the specified number of steps. Direction: 1 for forward, 0 for reverse.
|
|
- `SPEED <delay_us>`: Set the motor speed (delay in microseconds between steps).
|
|
- `LOG <message>`: Print a log message to serial.
|
|
|
|
## Firmware Files
|
|
- `src/main.cpp`: Main firmware logic, serial command parsing, motor control, logging.
|
|
- `src/ULN2003Stepper.h`, `src/Stepper.h`: Stepper motor driver classes.
|
|
|
|
## How to Extend
|
|
- Add new serial commands by updating the parser in `main.cpp`.
|
|
- Implement additional motor features or logging as needed.
|
|
- Ensure any new global variables are only defined in one source file, and declared as `extern` elsewhere.
|
|
|
|
## TypeScript Backend
|
|
- Use a library like `serialport` to communicate with the Pico.
|
|
- Send commands as plain text terminated by `\n`.
|
|
- Read and process log/status messages from serial.
|
|
|
|
## Example Serial Session
|
|
```
|
|
SPEED 3000
|
|
STEP 4096 1
|
|
LOG Motor moved
|
|
```
|
|
|
|
## Build & Upload
|
|
Use PlatformIO to build and upload the firmware to the Pico.
