MCP23017 Port Expander

The MCP23017 digital port expander allows you to expand the number of system inputs/outputs. Each expander can add an additional 16 ports to the system. The connection is made via the I2C bus using SDA and SCL control signals.You can connect up to 4 modules, thereby expanding the number of system ports to 64 digital inputs/outputs.For proper operation of the system, you need to connect the SDA and SCL, they must be connected to the power supply on the module, if this is not the case, then pull them up … Read more

Pin control button (relay control)

One of the simplest modules. Designed to control the Gpio configured as an output. Created by selecting the appropriate item in the menu. Next, fill in the Gpio number and, if necessary, turn on the output inversion. This determines which High or Low signal will be on the given Gpio when it is activated.

Button (physically connected)

This module is used to describe the input button. This is about a Gpio configured as an input. Int-not used yet Pin-Gpio number for this input pinMode-can be INPUT_PULLUP INPUT_PULLDOWN INPUTdebounceDelay — bounce processing timeexeclevel — trigger level High or LowfixState-input behavior, triggered on transition or on level fixation (trigger mode) For understanding … Read more
