arduino-softpwm | Software PWM library for Arduino

arduino-softpwm is a C++ library typically used in Internet of Things (IoT), Arduino applications. arduino-softpwm has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

software pwm library for [arduino] and other compatible avr boards. avr microcontrollers provide hardware pwm on some pins but if you need pwm on other pins then it must be implemented in software. this library provides easy and efficient software pwm on any pin. each channel can be set to a different pwm duty cycle. this library is licensed under [bsd3] see file > examples > arduino-softpwm > softpwm_example for demonstration of library usage. everything in this library except for preprocessor defines are wrapped in namespace palatis {}, so if your compiler blames you about symbol not found, try add palatis:: before that thing. for example, palatis::softpwm.size(). alternatively, you can add using namespace palatis; at the top of the source file to import everything under the palatis namespace, this might be convenient if you’re using my other libraries. #define softpwm_output_delay - add this line above #include for a 1 pwm clock cycle delay between outputs to prevent large in-rush currents. softpwm_define_channel(channel, pmode, port, bit) - configure a pin for software pwm use. consult the datasheet for your microcontroller for the appropriate port and bit values for the physical pin. this information is shown in the pinout diagram, for example: [atmega328p
