TM1637 is a kind of LED (light-emitting diode display) drive control special circuit with keyboard scan interface and it's internally integrated with MCU digital interface, data latch, LED high pressure drive and keyboard scan. This product is in DIP20/SOP20 package type with excellent performance and high quality, which is mainly applicable to the display drive of induction cooker, micro-wave oven and small household electrical appliance.
LibDriver TM1637 is the full function driver of TM1637 launched by LibDriver. LibDriver TM1637 provides digital tube display, keypad scanning and other functions. LibDriver is MISRA compliant.
/src includes LibDriver TM1637 source files.
/interface includes LibDriver TM1637 IIC platform independent template.
/test includes LibDriver TM1637 driver test code and this code can test the chip necessary function simply.
/example includes LibDriver TM1637 sample code.
/doc includes LibDriver TM1637 offline document.
/datasheet includes TM1637 datasheet.
/project includes the common Linux and MCU development board sample code. All projects use the shell script to debug the driver and the detail instruction can be found in each project's README.md.
