KAIstack and PIC24FJ -
basis for your KNX-application

Embedded system designs that employ KAIstack and the micro controller from Microchip gain access to the powerful, yet easy-to-use technology platform KAI (KNX Advanced Interface) for KNX enabled bus devices.
The PIC24F microcontroller family features cost effective, 16 MIPS 16-bit MCU performance and many devices with Microchip's eXtreme Low Power Technology. The PIC24F families incorporate USB-OTG, to act as a USB Device or Host, a Charge Time Measurement Unit (CTMU) that allows precision time measurement, capacitive measurement for mTouch™ applications and an integrated graphics controller to implement a graphical display interface what makes it easy to create modern KNX applications.
KAIstack is the main software component of KAI and provides the complete functionality needed for KNX devices.
KAIstack contains all elements required by the KNX standard and is certified in several different configurations. KAIstack is implemented in close dependence on the ISO/OSI reference model. The clear structure separates between application relevant parts, modular communication stack internal parts, media dependent parts and target CPU related issues. Advanced implementation methods allow highly efficient coding that leads to optimized resource usage.
This is shown in a small footprint and moderate resources needed. An application development with KAIstack relieves the burden of early decisions in the design process by simple configurability of the stack. It helps increase system reliability and improves device stability.
Hardware and software components of KAI can be adapted according to given conditions. KAIstack is KNX certified. 

Evaluation board for KAIstack with PIC24FJ

The evaluation boards for KAIstack with PIC24FJ MCU provides everything necessary to develop efficient KNX devices. The introduction of “Media-modules” gives the possibility to change the communication media used, during product development or even later. For the supported media KNX-TP, KNX-RF and KNX-IP we offer several different modules per media:TP: TP-UART, TP-UART galvanic isolation ,TPUART2, E981.03, NCN5110, KAIphys RF: SX1211 others in preparation.
Pushbuttons, LEDs and all MCU signals routed on pin header with standardized connections to “Media-modules”, provide an excellent development and test platform.
