Pms150c Yingguang MCU development case

PMS150C Yingguang MCU development case

    The price of Yingguang single chip microcomputer is beautiful , High cost performance ,mini-c To use , Suitable for consumer electronics development . But the case demo It's too short , In order to facilitate everyone to get started quickly . A classic is posted here PMS150C Lighting program code . No Hello world！ That kind of , It's the kind that favors the actual product .

There are many contents involved , It should include: PMS150C:

1. Port I / O configuration

2.Tmr16 Interrupt configuration （systick）, count down

3. Key detection , Including anti shake , It can be used for long key detection

4. low power consumption , Sleep configuration

5. Wake up the

6. System clock configuration , System clock switching

7. Watchdog application

8. State machine application

Others like PMS152,PMS132 The settings are similar , Hope you enjoy it ！
