I2c_ds1307_rtc example

This example demonstrates use of the i2c driver (Inter-Integrated Circuit) in KasperskyOS.

In this example, the I2cClient program uses the i2c driver interface.

The client library of the i2c driver is statically linked to the I2cClient program. The i2c driver implementation uses a BSP (Board Support Platform) subsystem for configuring clock frequencies (Clocks) and pins multiplexing (PinMux). Therefore, to ensure correct operation of the driver, you need to do the following:

  • Link the I2cClient program to the i2c_CLIENT_LIB client library.
  • Link the I2cClient program to the bsp_CLIENT_LIB client library.
  • Create an IPC channel between the I2cClient program and the kl.drivers.I2C driver.
  • Create an IPC channel between the I2cClient program and the kl.drivers.BSP driver.

The CMake system, which is included with KasperskyOS Community Edition, is used to build and run the example.

Example files

The code of the example and build scripts are available at the following path:

/opt/KasperskyOS-Community-Edition-<version>/examples/i2c_ds1307_rtc

Building and running example

This example is intended to run only on Raspberry Pi. For the example to work correctly, you must connect a DS1307Z real-time clock module to the i2c port.

See Building and running examples section.
