The first step consists in displaying "STM8L" string on LCD glass in scrolling mode. Then, "LP MODE" string is blinking on LCD glass before entering in HALT mode, When the MCU enters in Halt mode the " HALT " string is displayed on LCD glass. After 10 seconds the MCU wakes up from HALT mode (by RTC wakeup interrupt and continues processing. These Steps are repeated in infinite loop. On the STM8L1528-EVAL, In addition to the text zone the LCD Glass embeds more features(Matrix zone, Temperature indicator, Sign, ST Logo... all these predefined characters are permanently displayed during the execution. The LCD is configured as follow: - clock source = LSE (32.768 KHz) - Voltage source = Internal - Prescaler = 2 - Divider = 18 (16 + 2 - Mode = 1/4 Duty, 1/3 Bias - LCD frequency = (clock source * Duty) / (Prescaler * Divider) = 228 Hz ==> Frame frequency = 57 Hz @par Directory contents - LCD/LCD_SegmentsDrive/main.c Main file containing the "main" function - LCD/LCD_SegmentsDrive/stm8l15x_conf.h Library Configuration file - LCD/LCD_SegmentsDrive/stm8l15x_it.c Interrupt routines source - LCD/LCD_SegmentsDrive/stm8l15x_it.h Interrupt routines declaration @par Hardware and Software environment - This example runs on STM8L15x High-Density, Medium-Density Plus and Medium-Density Devices. - This example has been tested with STMicroelectronics STM8L1528-EVAL (STM8L15x High-Density devices) and STM8L1526-EVAL (STM8L15x Medium-Density devices) evaluation boards and can be easily tailored to any other development board. - STM8L1528-EVAL Set-up - LCD glass daughter board (MB905) - Make sure that the LCD glass daughter board (MB905) is mounted in LCD position. For more details please refer to the evaluation board user manual. - STM8L1526-EVAL Set-up - LCD glass daughter board (MB821) - Make sure that the LCD glass daughter board (MB821) is mounted in LCD position. For more details please refer to evaluation board user manual. @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 files : - stm8_eval.c (under Utilities\STM8_EVAL) - stm8l1528_eval_glass_lcd.c (if STM8L1528-EVAL is used, this file is under Utilities/STM8_EVAL/STM8L1528_EVAL or stm8l1526_eval_glass_lcd.c (if STM8L1526-EVAL is used, this file is under Utilities/STM8_EVAL/STM8L1526_EVAL - Rebuild all files and load your image into target memory - Run the example *
