* `Extra Wiki information <https://wiki.dfrobot.com/Gravity%3A%20IIC%20to%20Dual%20UART%20Module%20SKU%3A%20DFR0627>`_
Dependencies
=============
This driver depends on:
* `Adafruit CircuitPython <https://github.com/adafruit/circuitpython>`_
* `Bus Device <https://github.com/adafruit/Adafruit_CircuitPython_BusDevice>`_
* `DFROBOT Gravity: I2C to Dual UART Module Hardware <https://www.dfrobot.com/product-2001.html>`_
Please ensure all dependencies are available on the CircuitPython filesystem.
This is easily achieved by downloading
`the Adafruit library and driver bundle <https://circuitpython.org/libraries>`_
or individual libraries can be installed using
`circup <https://github.com/adafruit/circup>`_.
Installing from PyPI
=====================
On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally `from
PyPI <https://pypi.org/project/CircuitPython_DFRobot_Gravity_DRF0627_I2C_Dual_Uart/>`_.
To install for current user:
.. code-block:: shell
pip3 install CircuitPython_DFRobot_Gravity_DRF0627_I2C_Dual_Uart
To install system-wide (this may be required in some cases):
.. code-block:: shell
sudo pip3 install CircuitPython_DFRobot_Gravity_DRF0627_I2C_Dual_Uart
To install in a virtual environment in your current project:
.. code-block:: shell
mkdir project-name && cd project-name
python3 -m venv .env
source .env/bin/activate
pip3 install CircuitPython_DFRobot_Gravity_DRF0627_I2C_Dual_Uart
Installing to a Connected CircuitPython Device with Circup
==========================================================
Make sure that you have ``circup`` installed in your Python environment.
Install it with the following command if necessary:
.. code-block:: shell
pip3 install circup
With ``circup`` installed and your CircuitPython device connected use the
following command to install:
.. code-block:: shell
circup install CircuitPython_DFRobot_Gravity_DRF0627_I2C_Dual_Uart
Or the following command to update an existing version:
.. code-block:: shell
circup update
Usage Example
=============
.. code-block::
import time
import board
import CircuitPython_DFRobot_Gravity_DRF0627_I2C_Dual_Uart as DualUart
i2c = board.I2C()
iic_uart1 = DualUart.DFRobot_IIC_Serial(
i2c,
sub_uart_channel=DualUart.DFRobot_IIC_Serial.SUBUART_CHANNEL_1,
IA1=1,
IA0=1,
)
iic_uart2 = DualUart.DFRobot_IIC_Serial(
i2c,
sub_uart_channel=DualUart.DFRobot_IIC_Serial.SUBUART_CHANNEL_2,
IA1=1,
IA0=1,
)
try:
iic_uart1.begin(baud=9600, format=iic_uart1.IIC_Serial_8N1)
print("Opened: UART 1 ")
except Exception as e:
iic_uart1 = None
print("Error: Could not open UART 1 Exception: " + str(e))
try:
iic_uart2.begin(baud=9600, format=iic_uart2.IIC_Serial_8N1)
print("Opened: UART 2")
except Exception as e:
iic_uart2 = None
print("Error: Could not open UART 2 Exception: " + str(e))
sendID = 1
sendDelayCount = 1
while True:
time.sleep(.3)
sendDelayCount -= 1
if sendDelayCount <= 0:
sendDelayCount = 10
iic_uart1.write("From1:" + str(sendID))
iic_uart2.write("From2:" + str(sendID))
if iic_uart1 is not None:
if iic_uart1.available():
s = ""
while iic_uart1.available():
b = iic_uart1.read(1)
s += chr(b[0])
print("<1:" + s + " len:" + str(len(s)) + ">")
if iic_uart2 is not None:
if iic_uart2.available():
s = ""
while iic_uart2.available():
b = (iic_uart2.read(1))
s += chr(b[0])
print("<2:" + s + " len:" + str(len(s)) + ">")
Additional connection information
=================================
The DRF0627 comes with a cable that allows for connection to the CircuitPython hardware using a
SparkFun STEMMA QT / Qwiic Breadboard Breakout Adapter Product ID: 4527 https://www.adafruit.com/product/4527
.. image:: https://user-images.githubusercontent.com/70548834/187724117-4660a9b5-e877-4bf8-8dbe-a0c5a8d7ca6e.jpg

:target: https://www.adafruit.com/product/4527
:alt: SparkFun STEMMA QT / Qwiic Breadboard Breakout Adapter
Connections:
************
.. code-block::
Black wire -> Stemma Ground
Red wire -> Stemma 3.3 V
Green wire -> Stemma SDA
Blue wire -> Stemma SCA
To test the connection the "t" and "R" pins can be connected together. If you tie the "T" and "R" pins between the same UART the data will echo back to you on the same port. If you tie the "T" and "R" pins from UART1 to UART 2 data will be send between the two ports.
If RS485 is desired you can use a RS485 adapter such as the "SCM TTL to RS-485 Interface Module"
