Pulse wide modulator generator with up to 3 channels.
Connection
Every channels needs a port.
At the moment none of the standard boards has a pin configuration already implemented. It would not make much sense, because you would have to adapt it anyway.
So here a example you can modify and copy to the configuration of the board used:
ifdef(`conf_PWM', `dnl #ifdef CH_A_PWM_GENERAL_SUPPORT pin(CHANNEL_A_PWM, PC0, OUTPUT) #endif /* CH_A_PWM_GENERAL_SUPPORT */ #ifdef CH_B_PWM_GENERAL_SUPPORT pin(CHANNEL_B_PWM, PC1, OUTPUT) #endif /* CH_B_PWM_GENERAL_SUPPORT */ #ifdef CH_C_PWM_GENERAL_SUPPORT pin(CHANNEL_C_PWM, PC2, OUTPUT) #endif /* CH_C_PWM_GENERAL_SUPPORT */ ')
