For more details please refer to the evaluation board user manual. - IrDA transceiver (U6) is used, make sure that JP5 jumper is in IrDA position. - LED1..4 - Joystick - STM8L1526-EVAL Set-up - Make sure that the LCD glass daughter board is mounted in IO position. For more details please refer to the evaluation board user manual. - IrDA transceiver (U2) is used, make sure that JP5 jumper is in IrDA position. - LED1..4 - Joystick @par How to use it ? In order to make the program work, you must do the following : - Copy all source files from this example folder to the template folder under Project\STM8L15x_StdPeriph_Template - Open your preferred toolchain - Add the required file: - stm8_eval.c (under Utilities\STM8_EVAL) - In main.c file select if the board will act as - transmitter (USART_IrDA_TRANSMIT define enabled) - or receiver (USART_IrDA_RECEIVE define enabled ) - Rebuild all files and load your image into target memory - Run the example *
