4-Digit Seven Segment Display TM1637 (STM32F103C8T6)

TM1367 is a LED drive and keyboard scan controller but in this application it is uses for driving 4 digits seven segment display. There are 4 wires connecting the display and the microcontroller:

Display : MCU 
GND     - GND
VCC     - 5V
DIO     - Port A1
CLK     - Port A0


It communicate with I2C protocol that's why the code has below procedures:
- TM1637Start(void);
- TM1637Stop(void);
- TM1637ReadAck(void);

The example code init the mcu, init the TM1367 and then display integer counting from 0-9999 repeatedly. Get the code https://drive.google.com.

P10 Module x2 Running Text (STM32F103C8T6)

Interested to build a running text display made of two P10 modules? The text looks shaky on video but actually not, recording quality ...
