                                样例使用说明
                             Sample Description
================================================================================
功能描述：
此样例实现了定时器的互补输出功能，三组互补共六路pwm输出，此样例没有实现死区功能
CH1   ->  PB12
CH1N  ->  PB13
CH2   ->  PC13
CH2N  ->  PC11
CH3   ->  PC05
CH3N  ->  PC06

Function descriptions:
This sample demonstrates complementary output function of the timer,Three sets 
of complementary outputs total six pwm outputs, this example does not implement 
the dead zone function

测试环境：
测试用板：PY32T090_STK
MDK版本： 5.28
IAR版本： 9.20
GCC版本：GNU Arm Embedded Toolchain 10.3-2021.10

Test environment:
Test board: PY32T090_STK
MDK Version: 5.28
IAR Version: 9.20
GCC Version: GNU Arm Embedded Toolchain 10.3-2021.10
================================================================================
使用步骤：
1. 下载并运行程序
2. 通过逻辑分析仪捕捉上述六通道的电平，判断pwm输出信号是否正确

Example execution steps:
1. compile and download the program to MCU and run it;
2. Capture the level of the above six channels through the logic analyzer to 
determine whether the pwm output signal is correct
================================================================================
注意事项：
通过USB转TTL模块连接PC与STK板,STK板与USB转TTL模块的连线方式如下；
@PrintfConfigStart
STK板        USB转TTL模块
PB9(TX)   -->  RX
PB8(RX)   -->  TX
GND       -->  GND
UART配置为波特率115200，数据位8，停止位1，校验位None
@PrintfConfigEnd

Notes:
Connect the PC to the STK board through the USB to TTL module, and the connection
method between the STK board and the USB to TTL module is as follows:
@PrintfConfigStart
STK board USB to TTL module
PB9(TX)   -->  RX
PB8(RX)   -->  TX
GND       -->  GND
UART is configured as BaudRate 115200, data bit 8, stop bit 1, and parity None.
@PrintfConfigEnd
