i2c_bm8563_rtc example
i2c_bm8563_rtc example
This example demonstrates use of the i2c driver (Inter-Integrated Circuit) in KasperskyOS.
In this example, the Bm8563 program uses the i2c driver interface.
The client library of the i2c driver is statically linked to the Bm8563 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
Bm8563program to thei2c_CLIENT_LIBclient library. - Link the
Bm8563program to thebsp_CLIENT_LIBclient library. - Create an IPC channel between the
Bm8563program and thekl.drivers.I2Cdriver. - Create an IPC channel between the
Bm8563program and thekl.drivers.BSPdriver.
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_bm8563_rtc
Building and running the example
This example is intended to run only on Radxa ROCK 3A.
See Building and running examples section.
