Implements support for the TI TCAL6416 16-bit I2C I/O expander with the following features: - 16 GPIO pins (2 banks of 8) - Bidirectional I/O with configurable input/output modes - Support for inverted pins - Compatible with ESP32, ESP8266, and RP2040 platforms - I2C interface with configurable address (default: 0x20) The TCAL6416 provides higher current latched outputs suitable for directly driving LEDs or keypads. It operates at voltages from 1.08V to 3.6V and supports I2C speeds up to 1MHz. Addresses: https://github.com/orgs/esphome/discussions/3233
Tests for ESPHome
This directory contains some tests for ESPHome.
At the moment, all the tests only work by simply executing
esphome over some YAML files that are made to test
whether the yaml gets converted to the proper C++ code.
Of course this is all just very high-level and things like unit tests would be much better. So if you have time and know how to set up a unit testing framework for python, please do give it a try.
When adding entries in test_.yaml files we usually need only
one file updated, unless conflicting code is generated for
different configurations, e.g. wifi and ethernet cannot
be tested on the same device.
Current test_.yaml file contents.
