Device:
Evaluation Board:
Complier:
Tasks:
| task_init |
initialize the target board's resources, and create the majority of tasks, and then delete itself and exit the scheduling |
| lcd_display_adc |
display the current value of ADC on LCD1602 |
| uart_print |
print the current AD value of ADC by serial port |
| led_blink |
control the flashing of LEDs |
| time_display |
display time, the format likes xx:xx:xx |
| time_set |
set time |
| lcd_blink |

Descriptions:
1. This example simulates a real-time clock on LCD1602 which users can set time freely:
Press WKUP(S2) button to choose the hour, minute or second that you want to set, at the same time as set of exit(when press it the fourth time);
Press TAMP(S3) button to increase the hour,minute or second which was choosed to set by 1.
2. System samples the value of AD at regular intervals and show it by histogram on LCD1602, at the same time the serial port prints the value of AD.
You can adjust the input voltage of AD by the regulation resistance on board, and you could see the change on LCD1602 or through the serial print.
3. The 8 LEDs on board keep flickering by the style that set.
