The WREN SDK uses both ESP-12S GPIO and I2C GPIO Expander (MCP23017). to control and monitor the board functionality. For this reason, it is important to ensure your development supports the I2C Expander MCP23017. An example from Tasmota is MCP23017 GPIO Expander
This is a living (Work in Progress), document. Basics The heart of the WREN SDK is an ESP-12S, which is a small package variation to the industry standard ESP8266, so enabling a vast range of support from many IoT developers. Standard ESP8266 firmware will run on the WREN SDK, after simple assignment of ports to […]
The below PCB overview uses the beta version of the board.
The WREN 12S SDK V2 example code below is used for Board Bring Up and Test Input / Output Ports. This Arduino IDE example (Settings. Board: ESP8266 12S Dev Module), basically exercises the RGB LED, Temperature Sensor, Voltage Sensor, Safety Circuit, Inputs and DC Motor Outputs. You can also refer to Wiki for ESP-12S GPIO […]
Following the success of the original WREN SDK, the new DitroniX WREN 12S SDK v2, based on an Ai-Thinker ESP-12S (ESP8266), has been developed. DitroniX WREN, is an IoT Linear Motor Controller SDK. It was initially designed to easily, and safely, retrofit (plug and play), to industry standard Electric Reclining Chairs, with continued use of […]
The new DitroniX WREN 1 Consumer Edition has been designed to easily, and safely, retrofit to industry standard Electric Reclining Chairs. WREN could also be used for a range of other DC controlled applications. The principle function of WREN, is to interface to existing electric recliner push buttons (or remote hand controller), and provide both […]
The new DitroniX WREN is both a Consumer Product, and also a Developers SDK. It has been designed to easily, and safely, retrofit to industry standard Electric Reclining Chairs. WREN could also be used for a range of other DC controlled applications. A detailed comparison table is provided here The principle function of the DitroniX […]
