PWM Channel N

[dquy05]

Hi !

I need to use PWM of STM32F4, mode Channel N,
ex : PWM_TIM1_Start(_PWM_CHANNEL1, &_GPIO_MODULE_TIM1_CH1N_PE8); // setup channel N
But Mikroc don't support !

Can you help me !
Thanks!

Hello,

Which MCU are you using?

Hi !

I used STM32F407VGT6,
Mikroc can't creat a PWM channel N,
PWM_TIM1_Start(_PWM_CHANNEL1, &_GPIO_MODULE_TIM1_CH1N_PA7); // note CH1N

Thanks !

You have to enable the CCxNE bit in the TIMx_CCER register prior to calling the PWM_TIMx_Start() function.
In this case, add TIM1_CCER.B2 = 1; before your PWM_TIM1_Start(_PWM_CHANNEL1, &_GPIO_MODULE_TIM1_CH1N_PA7);

Also, I assume you added the _GPIO_MODULE_TIM1_CH1N_PA7 structure yourself? In case this doesn't work, please zip and attach your __Lib_GPIO_32F4xx_Defs.c file for inspection. It's located in:
C:\Users\Public\Documents\Mikroelektronika\mikroC PRO for ARM\Uses\ST M4
