Hi j wang,
感谢你对NXP MIMXRT 芯片的关注与支持，下面由我为你提供技术解答。
回答你的几个问题：
1.哪里可以下载到各个外设的库函数和例程？
答： 官方提供了完整的MIMXRT1060 SDK驱动以及例程，具体下载链接：
Welcome | MCUXpresso SDK Builder
点击select development board，然后在board里面选择EVK-RT1060，点击右边的build，
然后下载代码。
下载之后，你可以在压缩包里面看到一个doc文件夹，里面有具体教你怎么使用官方的SDK代码。
2.脉冲输出可以输出有相位差的脉冲吗？如何精确控制脉冲输出的个数？1个TIM或者PWM，可以在2个不同的引脚，分时输出脉冲吗？
答：这个完全是可以实现的，可以通过代码去配置相应的模块，具体输出多少个数，也完全可以通过代码去实现。
3.计数器支持脉冲+方向输入吗？1个TIM，可以在2个不同的引脚，1个对脉冲进行加计数，另1个对脉冲进行减计数吗？
答： quad Timer的counter可以实现count up/down， 具体你可以查看我们RT芯片的参考手册。关键还是结合手册上面硬件配置。
4.计数器一共有多少个，可以有外部时钟的有多少个？
答: RT芯片有很多的定时器，所以计数器也有很多，就以quad timer模块为例，就有4个16位counter，从手册中可以大致看到下面定时器的一些特性：
50.1 Overview
The following timers are supported in this chip:
• General Purpose Timer (GPT): A 32-bit up-counter with 12-bit pre-scaler
• Periodic Interrupt Timer (PIT): A 32-bit counter timer that features programmable
count modulus, clock division features etc.
• Quad Timer (TMR): It provides four timer channels with variety of controls for
individual and multi-channel features
• Quadrature Encoder/Decoder (ENC): It provides interfacing capability to position/
speed sensors
• Enhanced FlexPWM: It contains PWM submodules each of which is set up to control
a single half bridge power stage
• Watchdog Timer (WDOG1,2): The WDOG1 and WDOG2 protect against system
failures by providing a method by which to escape from unexpected events or
programming errors
• Watchdog timer (RTWDOG/WDOG3): It is a high reliability independent timer that
is available for system use
• External Watchdog Monitor (EWM): It is designed to monitor external circuits, as
well as the MCU software flow
可以支持的外部时钟的模块也比较多，具体你需要多少呢？可以根据你的具体要求选择具体的模块，然后再看具体的模块是否支持外部时钟，一般都是支持的，具体请查看下我们的手册。
如果还有任何问题，欢迎继续交流。
Have a great day,
Kerry
