Please refer to this post:&nbsp;<A href="https://community.nxp.com/t5/i-MX-RT-Crossover-MCUs/i-MX-RT1052-Is-it-possible-to-create-a-32bit-PWM-module-using-2/m-p/1428671" target="_blank">已解决: i.MX.RT1052 - Is it possible to create a 32bit PWM module using 2 quad timers? - NXP Community</A><BR /><BR />Maybe you can design the software to realize, eg, when the counter 16 bit is overflowed, then in the overflowed interrupt, you use a software count flag to record it. when the 16 bit overflow 0xffff times, it means the counter 32 bit is reached.<BR />Besides this, actually, PIT is the 32bit counter, maybe you can use the PIT associate with the GPIO to realize the PWM generation.<BR />Wish it helps you!</P> <P>Best regards,<BR />Gavin</P> Mon, 08 Jul 2024 08:07:44 GMT https://community.nxp.com/t5/i-MX-RT-Crossover-MCUs/imxrt1052-32bit-pwm/m-p/1901922#M31155 Gavin_Jia 2024-07-08T08:07:44Z https://community.nxp.com/t5/i-MX-RT-Crossover-MCUs/imxrt1052-32bit-pwm/m-p/2018140#M32972 <P>最终使用了pit来模拟pwm，中断中翻转IO，中断频率为pwm频率的2倍，占空比为百分50</P> Sat, 21 Dec 2024 09:29:07 GMT https://community.nxp.com/t5/i-MX-RT-Crossover-MCUs/imxrt1052-32bit-pwm/m-p/2018140#M32972 ccc_clive 2024-12-21T09:29:07Z
