Hello,

Actually I am working on brushless dc motor control by KEIL MCB4357 Development Board. I want to generate four PWM signal with MCB4357 Board. Each signal must have these basic parameters :

- Frequency : 400 Hz

- Duty Cycle : 40 %

- Amplitude : 3.3V

I read all datasheet about PWM Signal for KEIL MCB4357 but i found nothing about this. Can anyone help me to write a program which can generate these PWM signal with all parameter.

Thanks You

Hi,
There in an example to generate PWM using SCT. Please download CMSIS package from
http://www.lpcware.com/content/nxpfile/lpc4350apdlzip
Run example using Keil IDE from folder ..\lpc43xx-2013-09-04\lpc43xx\Examples\SCT\Sct_pwm\Keil

Hi imroun1992,
I saw only one error. Please define KEIL_BOARD or HITEX_BOARD in your header file.
