智能马桶是个好东西，上面有各种各样舒服的功能，通常配有一个遥控器，为了以防遥控器哪天坏掉又没法单独配，利用M5StickC来提前做一个遥控器备份。由于M5StickC只具备IR发射功能，因此使用IR unit先来对遥控器编码进行读取，通过IRremote8266这个库找到IRrecvDumpV2这个示例，先按示例获取到遥控码，再通过sendRaw进行发送。
运行环境准备：
M5StickC马桶型号
遥控信号
以下信号数据是对实际遥控信号的分析。按下按钮时，每个信号重复发送3次。
[td]
注1：“ 臀洗 / 轻柔 /冲洗/ 停止”按钮输出两种信号：“ Move On / Off”和“ Wash”。注2：实际的遥控器处于一种状态，如果在洗涤停止时按“臀洗/轻柔/冲洗”，则仅发送信号2（洗涤），而在洗涤时按信号，则发送信号1（“移动开/关”）。信号2（清洁）都被发送，并且由于该实施方式没有实际问题，所以信号1和信号2都总是被发送。
注3：遥控器还具有干燥状态，如果在干燥过程中再次按下“干燥”按钮，将发送与“停止”相同的信号。
实例
连接了连接到M5StickC的IR REMOTE单元以进行遥控器的红外信号分析，使用接收针脚编号33执行IRrecvDumpV2
远程控制程序将发送信号作为菜单显示在屏幕上，并通过按钮操作进行选择和发送。
使用按钮B /电源按钮前进/返回菜单项
使用按钮A发送选择的信号

遥控信号分析程序
该程序分析IRrecvDumpV2采集的原始数据，并将其转换为信号数据。我用Python编写了它，然后在Mac上运行了它，但是看起来像这样，因此可以将其合并到IRrecvDumpV2中。在不确认规格等的情况下，根据实际值调整值范围的判断值。
[mw_shl_code=python,true]import re
import fileinput
HDR_MARK = 6000
HDR_SPACE = 3000
BIT_MARK = 600
ZERO_SPACE = 600
ONE_SPACE = 1600
GAP = 40000
for line in fileinput.input():
line = line.strip()
if len(line) == 0:
continue
m = re.match('uint16_t rawData\[\d+\] = {([^}]+)};', line)
if m:
print(line)
print()
raw = list(map(lambda x: int(x), m.group(1).split(',')))
while len(raw) >= 2:
mark = raw.pop(0) # Skip Header Mark
space = raw.pop(0) # Skip Header Space
data = 0
bit_length = 0
while len(raw) >= 2:
mark = raw.pop(0)
space = raw.pop(0)
if (BIT_MARK-200) <= mark <= (BIT_MARK+200):
if (ZERO_SPACE-200) <= space <= (ZERO_SPACE+200):
print('0', end='')
data = data << 1
bit_length += 1
elif (ONE_SPACE-200) <= space <= (ONE_SPACE+200):
print('1', end='')
data = data << 1 | 1
bit_length += 1
elif (GAP-10000) < space < (GAP+10000):
break
else:
print()
print('Space Error:', space)
else:
print()
print('BitMark Error:', mark)
print(' 0x{:X} {:d} bit'.format(data, bit_length))
print()[/mw_shl_code]
这是通过使用上述程序处理“马桶盖打开/关闭”按钮的原始数据来确认输出3次0x2008000E0E信号的示例。
