The STM8AF board can perform both CAN and LIN communications with the MCU powered at 5 V and is ready to be connected into a network with its integrated transceiver. The STM8AL board manages LIN slave communication through its transceiver and uses a 4- digit alphanumeric LCD display with the MCU powered at 3.3 V, offering low energy power modes. Both STM8AF and STM8AL boards include push buttons, LEDs, external connectors and allow various configurations to take advantage of the numerous capabilities of the microcontrollers. 2 System requirements Windows PC (XP, Vista, 7) USB cable (dual type A to mini-B) - included 3 Development toolchains IAR: EWSTM8 STMicroelectronics: STVD 4 Demonstration software The demonstration software is preloaded in the board Flash memory. It uses the trimmer and the USER push buttons placed on the STM8AF board to switch via the LIN bus the LCD and the LEDs of the STM8AL board. The latest versions of the demonstration source code and associated documentation can be downloaded on the ST website. 2/4 Doc ID 023712 Rev 1
