seeed-python-reterminal

Python Library for reTerminal

This is a Python library which enables you to use the onboard hardware on the reTerminal. Currently the accelerometer, user LEDs, user buttons and buzzer can be accessed using this Python library.

Usage

User LEDs Test

import seeed_python_reterminal.core as rt
import time

print("STA ON, USR OFF")
rt.sta_led = True
rt.usr_led = False
time.sleep(1)

print("STA OFF, USR ON")
rt.sta_led = False
rt.usr_led = True
time.sleep(1)

print("STA RED, USR OFF")
rt.sta_led_green = False
rt.sta_led_red = True
rt.usr_led = False
time.sleep(1)

print("STA OFF, USR OFF")
rt.sta_led = False
rt.usr_led = False

Buzzer Test

import seeed_python_reterminal.core as rt
import time

print("BUZZER ON")
rt.buzzer = True
time.sleep(1)

print("BUZZER OFF")
rt.buzzer = False

User Buttons Test

import seeed_python_reterminal.core as rt
import seeed_python_reterminal.button as rt_btn


device = rt.get_button_device()
while True:
    for event in device.read_loop():
        buttonEvent = rt_btn.ButtonEvent(event)
        if buttonEvent.name != None:
            print(f"name={str(buttonEvent.name)} value={buttonEvent.value}")

Accelerometer Test

import seeed_python_reterminal.core as rt
import seeed_python_reterminal.acceleration as rt_accel


device = rt.get_acceleration_device()
while True:
    for event in device.read_loop():
        accelEvent = rt_accel.AccelerationEvent(event)
        if accelEvent.name != None:
            print(f"name={str(accelEvent.name)} value={accelEvent.value}")

Accelerometer and Buttons Test

import asyncio
import seeed_python_reterminal.core as rt
import seeed_python_reterminal.acceleration as rt_accel
import seeed_python_reterminal.button as rt_btn


async def accel_coroutine(device):
    async for event in device.async_read_loop():
        accelEvent = rt_accel.AccelerationEvent(event)
        if accelEvent.name != None:
            print(f"accel name={str(accelEvent.name)} value={accelEvent.value}")


async def btn_coroutine(device):
    async for event in device.async_read_loop():
        buttonEvent = rt_btn.ButtonEvent(event)
        if buttonEvent.name != None:
            print(f"name={str(buttonEvent.name)} value={buttonEvent.value}")


accel_device = rt.get_acceleration_device()
btn_device = rt.get_button_device()

asyncio.ensure_future(accel_coroutine(accel_device))
asyncio.ensure_future(btn_coroutine(btn_device))

loop = asyncio.get_event_loop()
loop.run_forever()

API Reference

• usr_led: Turn on/off green USR LED

rt.usr_led = True #Turn on green USR LED
rt.usr_led = False #Turn off green USR LED

• sta_led_red: Turn on/off red STA LED

rt.sta_led_red = True #Turn on red STA LED
rt.sta_led_red = False #Turn off red STA LED

• sta_led_green: Turn on/off green STA LED

rt.sta_led_green = True #Turn on green STA LED
rt.sta_led_green = False #Turn off green STA LED

Note: If red STA LED is on during this time, the green STA LED will turn on over the red STA LED

• sta_led: Turn on/off green STA LED

rt.sta_led = True #Turn on green STA LED
rt.sta_led = False #Turn off green STA LED

Note: If red STA LED is on during this time, the green STA LED will turn on and the red STA LED will turn off

• buzzer : Turn on/off buzzer

rt.buzzer = True #Turn on buzzer
rt.buzzer = False #Turn off buzzer

• get_button_device(): Obtain information about the buttons including all the events supported by them

device = rt.get_button_device()

• ButtonEvent(): Calls the ButtonEvent() and returns the EVENT

buttonEvent = rt_btn.ButtonEvent(event)

• get_acceleration_device(): Obtain information about the accelerometer including all the events supported by it

device = rt.get_acceleration_device()

• AccelerationEvent(): Calls the AccelerationEvent() and returns the EVENT

accelEvent = rt_accel.AccelerationEvent(event)
