How to use TM1637 Display Module?
As mentioned earlier the module communication can only be done using the two pins ‘DIO’ and ’CLK’ respectively. The data is sent to the module or received from the module though these two pins. So the characters to be displayed are sent in the form of serial data through this interface. A typical circuit diagram of display module interface to a controller is shown below.
The module can work on +5V regulated power and any higher voltage may lead to permanent damage. The interface is established as shown in figure. All you need to do is connect DIO and CLK to any of GPIO (General Purpose Input Output) pins of controller and establish serial data exchange through programming.
This serial data transmission between controller and module is really complex. So we will be using libraries which are written for the module to help with data transmission. All you need to do is download these libraries which are available in various websites and call them in application programs. Once the header file is included, the controller performs the communication by itself and required display characters will be sent to module.
The TM1637 IC on the module receives the serial data sent by the controller. The chip drives the 4 display segments according to the code. The segments light up to display the desired character.
