The board resources:
1. Turn CP2102 USB serial port to update the program (USBBOOT)
2. The TF card, the file system
3. Independent LED display CPU working condition
4. Reset circuit, the reset button
5. 8 m system crystal by PLL chip within 32 m Hz frequency doubling to high speed
6. PDI program download interface
7. All the IO lead
 
Basic programming examples:
1. The ADC sampling routine (including query mode and interrupt mode)
2. The analog comparator routines (query mode and window interrupt mode)
3. Guide the programming routines (via a serial port to load the application)
4. A 128 - bit key DES encryption engine routines
5. The clock system routines (internal)
6. 12 DAC output routines
7. The DMA controller operation routines
8. Internal EEPROM read and write routines
9. The event system operating routines
10. The application of the interrupt controller routines
11. IO interface input reads and interrupt routines
12. The internal real time clock RTC routines
13. The SPI interface to read and write routines
14. The timer routines

1) general timer interrupt
2) the input acquisition function
3) the signal frequency and duty ratio measurement
4) to produce PWM signal, adjustable duty ratio
5) event counter
6) will be combined into a two 16 bit timer 32-bit timers

15. TWI interface from the host machine routines
16. USART serial interface routines (query mode and window interrupt mode)
17. The watchdog routines (normal mode and window mode)
18. The FAT file system based on TF card
The inadequacy of UCOS operating system applications
