/** @page I2C_Interrupt I2C data transfer in interrupt mode @par Example description This example provides a short description of how to: - Transfer a data byte to a second I2C using interrupts. - In this example the code is written for a master I2C as we generate a START. - To perform the example in slave mode, just remove the START command line in the code. - The communication is configured in 7bit addressing mode with a clock speed set to 100KHz. - The event and buffer interrupts are enabled for the I2C. - Once the start signal is generated the interrupt function detects each interrupt and sequentially sends data till the STOP. - In case of Slave I2C, the start is not generated. This example runs on STM8S-128K and STM8S-32K products @par Directory contents - main.c Main file containing the "main" function - stm8s_conf.h Library Configuration file - stm8s_it.c Interrupt routines source - stm8s_it.h Interrupt routines declaration - stm8_interrupt_vector.c Interrupt vectors table @par Hardware environment 2 solutions: - Connect the STM8S I2C to a second I2C - SDA pin -> SDA pin. - SCL pin -> SCL pin. - On SDA & SCL pins do not forget pull-up resistors (4.7k ohms). - Do not forget to power up the EEPROM (VDD =5V). - Set the second I2C board with address 0xA0, frequency 100KHz. - Connect the STM8S I2C to an Aardvark I2C/SPI module - SDA pin -> SDA pin. - SCL pin -> SCL pin. - On SDA & SCL pins do not forget pull-up resistors (4.7k ohms). - Pull-up is integrated by default in the Aardvark module. - Set the Aardvark module as slave. In the graphical interface set address 0x50(=0xA0) in 100KHz. - Use same setting (add & frequency) if you use Aardvark in master mode (and your I2C device in slave mode). @par How to use it ? In order to make the program work, you must do the following : - Create a project and setup all project configuration - Compile the directory content files and required Library files : + stm8s_i2c.c + stm8s_gpio.c - Rebuild all files: Project->Rebuild all. - Load project image: Debug->Start/Stop Debug Session - In case where Aardvark is slave enable it as slave. - In case where Aardvark is master, run the program first then send the data with Aardvark interface. - Run program: Debug->Run (F5). - The buffer will be filled up with number of data you decided to capture. - The four LEDs will blink at the end of I2C communication sequence. Go to main file: I2C_Interrupt\main.c */ /******************* (C) COPYRIGHT 2008 STMicroelectronics *****END OF FILE****/
