How to Use FlexPwm PWMX Channel for RT1170 Output pwm，The configuration of PWMX is not supported in fsl_pwm. c. How should I go about it。

Hi @lkls ,

Thanks for your interest in NXP MIMXRT series!

There is a detailed post on driver support for PWMX channels in this thread, please refer to it: https://community.nxp.com/t5/i-MX-Processors/imxrt1024-flexpwm-PWM-X/td-p/1283963

But the good news is that our colleague implemented a register-based PWMX example using the board RT1170-EVKB, and I'm attaching the project here for your reference.

Note:
1. RT1170-EVKB J26 pin2 is the PWM2_X0 output.
2. RT1170 all FlexPWM interface can support the PWM_X output.
3. To one PWM, the PWMA, B X should use the same frequency.

Best regards,
Gavin
