Crate tm1637_gpio_driver 

Generic GPIO driver for TM1637. With this driver you can control for example the 4-digit 7-segment display from AZ-Delivery. This is not dependent on a specific GPIO library. This library was tested on a Raspberry Pi with its GPIO interface. Feel free to contribute. :)

Modules

fourdigit7segdis

Utility functions on top of the TM1637 driver to display content on the 4-digit 7-segment display by AZDelivery. You can use them but you don’t have to. They show how the driver works/could be used.

gpio_api

Provides ready to use setup functions for concrete GPIO libraries/drivers. You may use them but it is not required. You can learn from the code and write setup functions by yourself!

mappings

Provides mappings from symbols to their bit representation on a 7-segment display.

Structs

TM1637Adapter

Adapter between your code and the TM1637 via GPIO interface. You can use the GPIO interface/library that you want. Just provide the corresponding “glue” functions so that this adapter can access GPIO.

Enums

Brightness

The level of brightness. The TM1637 “DisplayControl”-command transports the brightness information in bits 0 to 2.

DisplayState

Whether the display is on or off. The TM1637 “DisplayControl”-command transports the display on/off information in the third bit (2^3) of the command.

GpioPinValue

The value of a GPIO pin.

ISA

The “ISA”/Commands of the TM1637. See data sheet for more information. This is only a subset of the possible values.

Constants

DISPLAY_REGISTERS_COUNT

According to the data sheet the TM1637 can address 6 display registers. Note that not all devices using it do as well. For example the 4-digit 7-segment display from AzDelivery only uses 4.
