programming of lpc 1758 pwm ?

ashrinshaikh — Thu, 09 Feb 2017 06:43:58 GMT

I have a lidar sensor there output is PWM and i want to give there pwm output as a input to lpc1758 and read the output and want to give the six pwm input at a time. Currently i am working with LPC 1758 .I didnot get the exactly link and peripheral about this. please help me for any suggestions or example code?

Hi Ashrin Shaikh,

Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.

I'd highly recommend you to refer to the PWM demo in the LPC175x_6x CMSIS-Compliant Standard Peripheral Firmware Driver Library whose link is below.

which given in the mail by you. i saw the examples from that i refer the

Ashrin,

attached is my PWM module (4 outputs and 4 inputs using CAP signals). This is for 1759, but it should be equal/very close to 1758. Hope code is understandable (I also found a couple of errors, again, in LPCOpen during the exercise)
