Unit ASR

Example

Send Hello voice command, execute Print program

from m5stack import *
from m5ui import *
from uiflow import *
import unit

setScreenColor(0x222222)
asr_0 = unit.get(unit.ASR, unit.PORTC)

def asr_0_hello_event(args):
  # global params
  print('I am Fine')

asr_0.init(2)
asr_0.add_command_word(0x32, 'hello', asr_0_hello_event)
print((str('raw message:') + str((asr_0.get_current_raw_message()))))
while True:
  asr_0.handler()
  wait_ms(2)

API

asr_0.init(2)

• Initialize Unit

def asr_0_hello_event(args):
  # global params
  pass

• Callback function triggered when Unit ASR recognizes a command word

print((str('current command handler state:') + str((asr_0.get_command_handler()))))

• Check if the current command has an associated handler

print((str('current command list:') + str((asr_0.get_command_list()))))

• Get a list of all commands and their associated handlers

print((str('current command num:') + str((asr_0.get_current_command_num()))))

• Get the current command number

print((str('current command word:') + str((asr_0.get_current_command_word()))))

• Get the command word corresponding to the current command number

asr_0.add_command_word(0x32, 'hello', _)

• Register custom commands and handlers

print((str('current raw message:') + str((asr_0.get_current_raw_message()))))

• Get the raw message received in hexadecimal format

print((str('receive message:') + str((asr_0.get_received_status()))))

• Get the message reception status

asr_0.remove_command_word('hello')

• Remove command words from the command list by word

print((str('command word:') + str((asr_0.search_command_num('')))))

• Search for the command number associated with a command word

print((str('command word(hex):') + str((asr_0.search_command_word(0x32)))))

• Search for the command word associated with a command number

asr_0.send_message(0xFE)

• Send a command via UART

asr_0.handler()

• Update function
