Connecting Raspberry Pi UART to control peripherals

Configure the system serial port

1) Enter the terminal and execute:

sudo nano /boot/cmdline.txt

put the following line: 

wc_otg.lpm_enable=0 console=ttyAMA0,115200 kgdboc=ttyAMA0,115200 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline rootwait

Change it to the following line: 

dwc_otg.lpm_enable=0 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4
elevator=deadline rootwait

Press Ctrl+X and select Y to save. 2) Execute: 

sudo nano /etc/inittab

find the following line: 

#Spawn a getty on Raspberry Pi serial line
T0:23:respawn:/sbin/getty -L ttyAMA0 115200 vt100

change to 

#Spawn a getty on Raspberry Pi serial line
#T0:23:respawn:/sbin/getty -L ttyAMA0 115200 vt100

Press Ctrl+X, select Y to save
3) Execute:

sudo reboot

After executing this command and restarting the Raspberry Pi, you will not be able to enter the Raspberry Pi terminal from the serial port. At this time, if the user wants to enter the terminal, he must use SSH or connect the Raspberry Pi to an external monitor and enter the LX terminal. (If you want the serial port to be used as the debug output of the Raspberry Pi serial port again, you can restart after restoring the changes, so it is best to back up before making changes)

Serial data display

1. Set the jumpers on the ARPI600: connect CP_RX to P_TX, and CP_TX to CP_RX.
2. Start the PuTTY serial debugging software to configure following parameters:

  • Serial line: it is used to select corresponding serial port.
  • Speed: it is used to set the Baud rate: 9600 (Notices: the parameter Speed in here is set to 9600, differently from the configuration shown in the figure).
  • Connection type: this option should be set to Serial.

3. Copy the file program/Xbee/send into the Raspbian, and enter the folder send, then, execute the following code:

sudo make
sudo ./serialTest

The terminal will display the data as

  4. Click the button Write to download the configured parameters into the XBee-A module

Configuring XBee-B module

  1. Configure the XBee-B module according to the processes described in the Section 3.1 and the Section 0. However, there is something different. In configuring XBee-B, you should select the option ZIBGEE COORDINATOR AT under the pull-down menu Function Set:
    Selecting the option ZIBGEE COORDINATOR AT under Function Set
    ARPI600-UserManual-12.jpg

  3. Click the button Write to download the configured parameters into the XBee-B module.
  4. To implement a simple P2P network, please configure XBee-A and XBee-B according to the processes described above. Start two X-CTU tools, and select different COM interfaces in the option PC Settings to control Group A and Group B respectively.
  5. Input the data to be transmitted in the X-CTU Terminal of XBee-A, then, you can find that the inputted data will be sent to XBee-B automatically, and displayed in the X-CTU Terminal of XBee-B. In the X-CTU, data in blue is the data to be sent, and data in red is the received data.
    Data transmission and receive

  6. This Figure shows the normal operating state of the XBee module.

Raspberry Pi transmits data wirelessly via XBee

After making sure that the wireless transmission network of 2 XBee is normal, now the Raspberry Pi can transmit data wirelessly through XBee.
1) Set the ARPI600 jumper:
Connect the two Raspberry Pi serial ports for sending and receiving to the XBee serial port, and the ARPI600 expansion board jumpers according to the red frame in the figure below.

  • XB_RX connects to P_TX
  • XB_TX connects to P_RX

XBTX.png
2) Test the Raspberry Pi serial port:
Execute: 

cd /Xbee/getdata
sudo make
sudo ./serialTest

The serial terminal prints out the following
Cd.png
Run the sender code again, copy program/Xbee/send to the sender Raspberry Pi system, enter the send folder, and execute.
sudo make sudo ./serialTest Then the receiver will print the received data:
Xbee2.png

RTC clock

  1. Set the jumpers on RTC JMP of the ARPI600.
  2. Open the LXTerminal on the desktop of Raspbian, and input the code:
    i2cdetect -y 1
  3. Then, you will see the device address of PCF8563 connected to Raspberry Pi. Here, the device address of PCF8563 is 51, which means the PCF8563 is identified by Raspberry Pi.
    The device address of PCF8563 connected to Raspberry Pi
    ARPI600-UserManual-17.jpg
  4. Enter LXTerminal, and run:
modprobe i2c-dev
echo pcf8563 0x51 > /sys/class/i2c-adapter/i2c-1/new_device
hwclock -r# (time to read the connected I2C hardware RTC)

LXTerminal will print out the PCF8563 time, which is different from the system time.

  1. Execute in LXTerminal
hwclock -w # (write the time of the Raspberry Pi system to PCF8563)
hwclock -r # (The time of the Raspberry Pi system is synchronized to the PCF8563)
hwclock -s # (set the system time to synchronize with the hardware's RCT clock)

AD conversion (ARPI600 on-board chip TLC1543)

Configuring Pin A0 to Pin AD

  1. Please make sure you have installed relative libraries (refer to the Section 2.2: Installing relative libraries).
  2. Set the jumpers to select reference voltage:
    • Connect REF to 5V, which means the AD conversion reference voltage is 5V (connecting to 5V is a default setting).
    • Connect REF to 3V3, which means the AD conversion reference voltage is 3.3V.
    Notices: REF can only be connected to one reference voltage at a time.
    Setting AD reference voltage
    ARPI600-UserManual-18.jpg
  3. Copy the file program/AD_TLC1543 in to Raspbian. Then, enter the folder AD_TLC1543, and execute the following code under the terminal:
    sudo make
    sudo ./tlc1543
  4. Terminal will display relative AD conversion value. By default, the displayed conversion value comes from Pin AD0 on TLC1543 (Pin T_A0 on ARPI600).
  5. Connect the jumpers T_A0 to A0, then the Pin A0 on the Arduino interface can serve as an AD conversion pin, as shown.
    connecting Pin T_A0 to Pin A0
    ARPI600-UserManual-19.jpg

Configuring as other AD pins

  1. If you want to display the conversion value from other AD pins on TLC1543, please enter the terminal and edit the file tlc1543.c:
    sudo nano tlc1543.c
    Find out the following line:
    re=ADCSelChannel(0);
    Modify the "0" in the line into the number corresponding to the other AD pins (For example, modify to "1" for testing the conversion value from Pin AD1 (Pin T_A1), and modify to "2" for testing the conversion value from Pin AD2 (Pin T_A2), and so on, until to "10" for testing the conversion value from Pin AD10 (T_A10)).
    After completing the operation described above, press the keys Ctrl+X, and select the option Y to save the modification.
  2. Execute the following code under the terminal:
    sudo make
    sudo ./tlc1543
    Now, the modification is in effect.


Interface description

Interface overview

The default relationship between Arduino digital control pins and Raspberry Pi IOs is shown in the table. The relationship between Arduino digital control pins and Raspberry Pi IOs

The jumper pins D11, D12 and D13 on the module are used for configuring the ARPI600. And these pins should be shorted by the 0Ω resistances.

Configuring the jumpers D11, D12 and D13
ARPI600-UserManual-20.jpg

In factory settings, the jumpers are set as follows:

  • Connect SCK to D13
  • Connect MISO to D12
  • Connect MOSI to D11

The following settings are connecting pins D11, D12, and D13 to the general IO control pins of the Raspberry Pi board.

  • Connect D13 to P26
  • Connect D12 to IO_SD
  • Connect D11 to IO_SC

Notices: Users can modify the settings of these jumpers as required. In this operation, welding is required. Any changes under no guidance from Waveshare will be considered as a waiver of warranty.

The pins A0-A5 of ARPI600 can also be configured as IO pins or ADC pins.

configuring Pins A0-A5
ARPI600-UserManual-21.jpg

a) When the pins A0-A5 are connected to 1, they will sever as IO control pins. The relationship between the pins A0-A5 and the pins of the Raspberry Pi board is as the table shows.

b) When the pins A0-A5 are connected to 3, they will sever as ADC pins.

You can also connect the pin A4 to P_SCL, and the pin A5 to P_SDA (as the figure shows), to make them serve as I2C control pins of the Raspberry Pi board. However, in default settings, the pins A4 and P_SCL are disconnected, and so are the pins A5 and P_SDA.

Notices: Users can modify the settings of these jumpers as required. In this operation, welding is required. Any changes under no guidance from Waveshare will be considered as a waiver of warranty.

In which:

  • The pins on A are connected to the ADC pins A6-A10 of TLC1543;
