  • I2C/I2C_Master/I2C_Master.uvoptx MDK5 project options file
  • I2C/I2C_Master/JLinkSettings.ini Jlink settings file
  • I2C/I2C_Master/main.c Main program
Hardware and Software environment
  • Hardware environment
    • The chip pins are connected as follows:
      • UART1 (PD5, PD6) is connected to PC serial port
      • I2C (PC3, PC4) is connected to eeprom 24c02
How to use it ?

In order to make the program work, you must do the following :
