Library for esp-open-rtos SDK to manage inputs from built-in GPIOs and MCP23017 interfaces.
When MCP23017 is used, GPIOs must be declared with this:
adv_button_create(GPIO + (MCP_Index * 100), I2C Bus, Inverted, MCP Address);
Where MCP_Index is the number from 1
to enumerate all MCP boards, in case that several boards are used.
Requirements:
- Timers Helper: https://github.com/RavenSystem/timers-helper
- Advanced I2C: https://github.com/RavenSystem/adv-i2c
