A pythonic way to access the teensytoany board
* See: https://github.com/ramonaoptics/teensy-to-any
To program the teensy to any devices you will need the following additional dependencies:
* `click`
* `appdirs`
* `requests`
You can install them with:
```bash
conda install click appdirs requests
# or
pip install click appdirs requests
```

# History
## 0.11.1 (2025-07-18)
* Provide an ability to define the device name at initialization time.
## 0.11.0 (2025-06-14)
* Try to automatically connect to devices with Manufacturer TeensyToAny. This
requires firmware version 0.13.0 and up.
## 0.10.2 (2025-06-02)
* Fix I2C scanning command line utility by absorping the errors when no device
is detected on the bus. Tested with a Teensy 4.0 and Sparkfun ISM330DHCX
QWIIC board.
## 0.10.1 (2025-05-27)
* Attempt to fix i2c command line utility by correctly initializing the I2C bus.
## 0.10.0 (2025-05-26)
* Provide an i2c scan capabilities through the python api as well as a command
line utility: `teensytoany_i2c_scan`.
## 0.9.0 (2025-05-16)
* Provide capabilities to program devices with board specific firmwares. #38
## 0.8.0 (2025-04-10)
* Automatically increase the timeout when issuing pulse commands to enable
longer pulse durations.
## 0.7.0 (2025-03-12)
* Add support for Wire1 I2C interface.
## 0.6.0 (2025-03-09)
* Provide a method to control LEDs through FastLED.
## 0.5.0 (2024-11-10)
* Provide control over the startup and demo commands.
* Ensure that potentially undefined variable is defined.
## 0.4.0 (2024-04-05)
* Provide functions to fetch local and remote firmware versions.
* Provide a static method to program the latest firmware version and a CLI to
do so from the terminal.
## 0.3.0 (2024-04-02)
* Add a `timeout` property to the functions that deal with updating the firmware.
## 0.2.0 (2023-11-07)
* Add a `timeout` property to simplify modifying the command timeout.
## 0.1.0 (2023-09-29)
* Provide access the new `mcu` command that reveals the microcontroller used at
the time of firmware programming.
* Provide an internal method that can be used by developers to update to the
latest firmware.
## 0.0.34 (2023-08-26)
* Small fixup in how reading the Teensy's registers is done to ensure better
forward compatibility.
## 0.0.33 (2023-08-26)
The following features require teensy-to-any version 0.0.23 or greater
* Add support for `gpio_digital_pulse`.
* Add support for `analog_pulse`.
* Add support for new `value` parameter for `gpio_pin_mode`.
* Add support to read the data returned from `spi_transfer_bulk`.
## 0.0.32 (2023-08-30)
* Address bugs in reading the values from Teensy's registers.
## 0.0.31 (2023-08-21)
* Add the ability to read and write to the teensy's registers.
## 0.0.30 (2023-04-03)
* Increase default timeout to 0.2 seconds from 0.1. This helps receive error
messages from missed I2C communications.
* Return an error if no response is returned from a standard command indicating
a timeout.
## 0.0.29 (2023-03-06)
* Try to avoid racy conditions in version reading
* Flush buffers upon startup to help with crash recovery.
## 0.0.28 (2023-03-04)
* Make the error message when no device is found more human friendly.
## 0.0.27 (2022-10-16)
* Use packaging instead of distutils for version identification
## 0.0.26 (2021-09-13)
* added function `spi_read_byte` enabling the user to read SPI register.
## 0.0.25 (2021-07-14)
* added function `analog_read` enabling the user to read analog signals.
## 0.0.24 (2021-06-03)
* added `i2c_read_payload and` `i2c_write_payload functions` which allows users to read and write a contiguous payload of bytes
## 0.0.23 (2021-02-13)
* Ensure compatibility with pyserial 3.X
* Power a ``start_poweroff`` parameter to ``TeensyPower`` to start the device
in the on state.
* Added the ability to close and open the device without deleting the python
object.
## 0.0.22 (2020-06-18)
* Added the ability to control a power switch that is connected to the
nominally on port.
## 0.0.20 (2019-12-14)
* Added capabilities for SPI and Analog functions
## 0.0.16 (2019-11-30)
* `TeensyPower` destructor will not raise an error when the device had failed
to open.
## 0.0.15 (2019-11-29)
* `TeensyPower` devices will automatically poweroff the output when
closed.
## 0.0.14 (2019-11-29)
* Added the specialized `TeensyPower` driver.
## 0.0.13 (2019-11-20)
* Added a few more serial numbers to the `teensytoany.known_devices`
## 0.0.1 (2019-11-07)
* First release on PyPI.
