CMSIS-Driver defines generic peripheral driver interfaces for middleware making it reusable across a wide range of supported microcontroller devices. The API connects microcontroller peripherals with middleware that implements for example communication stacks, file systems, or graphic user interfaces. More information and usage methord please refer to http://www.keil.com/pack/doc/cmsis/Driver/html/index.html.The cmsis_i2c_dma_b2b_transfer_slave example shows how to use i2c driver as slave to do board to board transfer with a DMA master:In this example, one i2c instance as slave and another i2c instance on the other board as master. Master sends a piece of data to slave, and receive a piece of data from slave. This example checks if the data received from slave is correct.

More information and usage methord please refer to http://www.keil.com/pack/doc/cmsis/Driver/html/index.html.The cmsis_i2c_read_accel_value example shows how to use CMSIS I2C driver to communicate with an i2c device: 1. How to use the i2c driver to read a i2c device who_am_I register. 2. How to use the i2c driver to write/read the device registers.In this example, the values of three-axis accelerometer print to the serial terminal on PC throughthe virtual serial port on board.
