我现在Jetson Orin Nano 上面开发ppm驱动但是遇到了很多源码上面的错误请问官方有没有标准的PPM驱动？
Hi jingyi.Li,
Sorry that I’m not aware of ppm driver.
Could you elaborate on this and what’s your use case?
Or are you asking for PPS?
If so, have you connected a PPS source?
Linux系统中，PPM（Pulse Position Modulation）信号通常用于测量电机的转速或进行FOC（Field-Oriented Control）控制。
PPM信号把多路PWM信号调制到一路通道上，发送到接收机后再由接收机还原成多路PWM从各个通道输出。
PPS和PPM驱动是不同的我已经适配了PPS驱动。
这篇帖子和我问题一样。
May I know what’s your use case for PPM?
Do you want to control the fan speed through PWM?
or you have connected any module on Orin Nano?
If so, please provide more details about your use case.
我想使用ppm控制无刷电机。不是控制风扇我已经适配了pwm和pps驱动，现在只是想要适配ppm驱动。
Please share the the block diagram of your connection with the motor.
And we need more details about “ppm” driver so that we can find if it exists in upstream linux. (ppm.c?)
