CircuitPython helper library for working with CSV files

This driver depends on:

• Adafruit CircuitPython
• MicroPython's regular expression library (re)

You can find which Adafruit boards have the re library here.

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle or individual libraries can be installed using circup.

Make sure that you have circup installed in your Python environment. Install it with the following command if necessary:

pip3 install circup

With circup installed and your CircuitPython device connected use the following command to install:

circup install circuitpython-csv

Or the following command to update an existing version:

circup update

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:

pip3 install circuitpython-csv

To install system-wide (this may be required in some cases):

sudo pip3 install circuitpython-csv

To install in a virtual environment in your current project:

mkdir project-name && cd project-name python3 -m venv .venv source .venv/bin/activate pip3 install circuitpython-csv

import board import sdcardio import storage import circuitpython_csv as csv # Initialize SD card spi = board.SPI() sdcard = sdcardio.SDCard(spi, board.D10) vfs = storage.VfsFat(sdcard) storage.mount(vfs, "/sd") # Write the CSV file! with open("/sd/testwrite.csv", mode="w", encoding="utf-8") as writablefile: csvwriter = csv.writer(writablefile) csvwriter.writerow(["I", "love", "CircuitPython", "!"]) csvwriter.writerow(["Spam"] * 3)
