I would like to use the MCPWM as a normal PWM output, because the mbed pwm is already in use. Can somebody help me what I should configure to control p1.19? I tried already this, but on the scope I get a DC value 0f 2.36V: Power up MCPWM LPC_SC->PCONP |= 1<<17; PCLK = CCLK (100MHz in our case) LPC_SC->PCLKSEL0 |= 1<<30; Configuring P1.19 = 33 as MC0A LPC_PINCON->PINSEL3 |= (1<<6); Set the Limit register (MCLIM0-2 is named as MCPER0-2 in CMSIS source file) LPC_MCPWM->MCPER0 = 5555; Start MCPWM channels 0 LPC_MCPWM->MCCON_CLR = 0xffffffff; LPC_MCPWM->MCCON_SET = (1<<0); LPC_MCPWM->MCPW0 = 2777; My idea is to get a frequency of 180 Hz and a duty cycle of 50%. Thanks in advance.
