功能描述：
|
|
|
此样例演示了TIM1的编码器接口模式。TIM1配置为编码器接口模式3，PA8和PA9配置为通道1
|
|
|
和通道2,当PA8输入信号的上升沿在前，PA9输入信号上升沿在后时TIM1向上计数，反之向下
|
|
|
计数。开启通道1和通道2的捕获中断，在中断中打印当前CNT值。

Function descriptions:
|
|
|
This sample demonstrates the encoder interface mode of TIM1. TIM1 is configured
|
|
|
in encoder interface mode 3, with PA8 and PA9 configured as channel 1 and
|
|
|
channel 2, respectively. When the rising edge of the input signal on PA8 occurs
|
|
|
before the rising edge of the input signal on PA9, TIM1 counts up; otherwise,
|
|
|
it counts down. The capture interrupts for channel 1 and channel 2 are enabled,
|
|
|
and the current CNT value is printed in the interrupt.

测试环境：
|
|
|
测试用板：PY32F403_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: PY32F403_STK
|
|
|

|
|
使用步骤：
|
|
|
1. 编译下载程序到MCU，并运行
|
|
|
2. 在PA8和PA9输入相位不同的脉冲
|
|
|
3. 连接串口打印当前计数值（不断累加或递减，由输入脉冲时序决定）
|
|
|
|
|
|
Example execution steps:
|
|
|
1.Compile and download the program to the MCU, and then run it.
|
|
|
2.Input pulse signals with different phases on PA8 and PA9.
|
|
|
3.Connect a serial port to print the current count value (it will increment
|
|
|
or decrement based on the timing of the input pulses).
