Then timer will generate interrupt every 0.01ms. In timer interrupt service routing, you put a new DAC output value.</P> <P>&nbsp;</P> <P>Regards,</P> <P>Jing</P> Thu, 28 Apr 2022 08:47:31 GMT https://community.nxp.com/t5/Processor-Expert-Software/KL25z-sawtooth-wave/m-p/1450557#M5081 jingpan 2022-04-28T08:47:31Z
