Command (m for help): p Disk /dev/mmcblk0: 7.3 GiB, 7820279808 bytes, 15273984 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0x15ae16d5

  Install

• Download the image from the URLIOT-House_old_pc_xx.7z
• Unzip the downloaded file, IOT-House_old_pc_xx.7z, and write IOT-House_old_pc_xx.img to flash memory, for example dd command

  1	dd if=IOT-House_old_pc_xx.img of=/dev/sdb bs=100M

  After installing the flash memory and MM-CP2112A to the USB of the laptop computer, turn on the power, it may take about 5 minutes to start up.

Setting

• When the login screen appears, log in with user: remote, password: hand

• Set the network settings according to each environment. By default, the preferred LAN and host name iot000

• From another PC, log in with user: remote, password: hand at http://iot000.local

• Set when the Control panel is displayed

• Once the network settings are complete, you can shorten the startup time without the following command GUI.

  1	sudo systemctl set-default multi-user.target

  
  

• The setting method is the same as IOT-House of raspberry pi

What is CP2112?

• USB<->I2C conversion chip (Silicon Laboratories Single-Chip HID USB to SMBus Master Bridg) for Linux and Windows USB You can use 8 GPIOs and I2C from, here we are using the module board of Sunhayato’s MM-CP2122A.

• MM-CP2122A Selling phraseI2C connection sensor and GPIO (8 pin) can be controlled directly from a PC application without programming the microcomputer. is a difficult task, and programming requires an understanding of the HIDAPI and CP2112 interface specifications below.

  • Hidapi Reference
  • CP2112 Reference AN495: CP2112 Interface Specification
  • I2C connection device verified this time BME680 hardware data

• When I connect to the USB of my lubuntu lts 18.04 Linux machine, the driver is loaded as shown below and the HID device is recognized.

• Programming example, SMBus Devices operation only Extract from source and explain only important parts, check the source for others. (Experience shows that GPIO needs to be operated in multiple processes, so there is a considerable amount using semaphore.)

  • CP2112’s I2C connection device BME680 sets the I2C address, required commands, data, and byte counter in the buffer, sends it with hid_send_feature_report, and waits for a response to the command if necessary.
  • The BME680 write sets the command(CP2112_DATA_WRITE), register address, data, and number of bytes and writes it to the device.

What is serial communication software epicon?

• epicon is a Linux serial communication software.

• In practice IOT House uses the thermo-hygrometer AM2321 sensor and AI/DIO for control with TOCOS TWE-Lite via serial communication from the USB connection ToCoStick of Raspberry Pi.

• I think that network devices such as Switch and Router that can be configured with serial ports and console PCs can be used regardless of manufacturer or model.

• When automating the settings, Cisco Switch and Router copy and paste the text data created in advance and fill in the config.
  At this time, it is important to send delay of characters and line breaks to prevent the config data from being missed.

• epicon supports the transmission delay of important characters and line breaks as this serial console, and you can copy and paste the config with confidence.

• In addition, file transfer software such as simple telnet and zmodem, shell, macro, start of external software, etc. CUI, but it is multifunctional and compact.

Make a simple illuminometer with a solar panel of a one dolloar calculator

• Measure the generated voltage of the solar panel with the analog input of TWELITE DIP

• Graph the analog input voltage, correct the variation of the generated voltage depending on the measurement location with the slice voltage, and digitize it as high/low

• Detect sunrise and sunset at high/low, turn on/off the entrance lamp
  • Do not simply turn the entrance lamp on and off at high/low (sunset/sunrise)
  • Turns off for 30 seconds (30000ms) every 5 minutes in consideration of crime prevention and energy saving.
  • Specific settings are done in Auto Process Tab
    • Every 5 minutes from 17:00 to 24:00, outdoor illuminance=low is judged and entrance lamp->low(30seconds)30 seconds after turning off, it lights for about 4 and a half minutes.
    • Every 5 minutes from 0 to 6 o’clock, Outdoor illuminance=low is judged and Entrance lamp->low(30seconds)
    • Every 5 minutes from 5 to 7 o’clock, Outdoor illuminance=high is judged and entrance lamp->low The lamp turns off after sunrise

What is pepogpioctld

• It is a daemon that quantifies the air quality based on the input / output control of gpio and the data of the environmental gas sensor BME680.

• When the BME680 sensor is connected, the gas resistance value is 50 counts every 5 minutes from the 2021/02/04/17:22: 23,10.2,43.0,1018.9,3436 value created by pepobme680. Based on the average value of 80%, temperature of 10%, and humidity of 10%, the following air quality: IAQ (indoor air quality) is calculated and added.

• IAQ is Sample 0(Good) to 500(Hazardous) Temperature(17-28℃):10% Humidity(40-70%):10% Gas(Gas±Gas_base/Gas_base):80%
