The I2C1 is configured in Master transmitter during transmission phase and in Master receiver during receive phase. However, I2C0 is configured as Slave receiver during transmission phase and as slave transmitter during receive phase. The Own I2C0 address is defined to 0xA0. The speed is set to the maximum frequency of 400kHz for both I2Cs. In the first part, the Master send the I2C1_Buffer_Tx to be received by the Slave. Then data read by the I2C0 peripheral and stored in the I2C0_Buffer_Rx is compared with the expected values of transmitted buffer. The result of this comparison is stored in the "TransferStatus1" variable. In the second part, The Slave send the I2C0_Buffer_Tx to be received by the Master Then data read by the I2C1 peripheral and stored in the I2C1_Buffer_Rx is compared with the expected values of transmitted buffer. The result of this comparison is stored in the "TransferStatus2" variable. Directory contents ================== 91x_conf.h Library Configuration file 91x_it.c Interrupt handlers 91x_it.h Interrupt handlers header file main.c Main program readme.txt This file Hardware environment ==================== Connect both I2C0 and I2C01 pins as following: - Connect I2C0_CLKOUT(P2.0) to I2C1_CLKOUT(P2.2). - Connect I2C0_DOUT(P2.1) to I2C1_DOUT(P2.3). - Connect a pull-up resistor to both CLKOUT and DOUT lines How to use it ============= In order to make the program work, you must do the following : - Create a project and setup all your toolchain's start-up files - Compile the directory content files and required Library files : + 91x_lib.c + 91x_i2c.c + 91x_gpio.c + 91x_scu.c + 91x_vic.c + 91x_fmi.c - Link all compiled files and load your image into Flash - Run the example ******************* (C) COPYRIGHT 2007 STMicroelectronics *****END OF FILE****
