Language:C 0khoih-prog / Dx_Slow_PWM
This library enables you to use ISR-based PWM channels on Arduino AVRDx-based boards (AVR128Dx, AVR64Dx, AVR32Dx, etc.), using DxCore, to create and output PWM any GPIO pin. It now supports up to 64 ISR-based PWM channels, while consuming only 1 Hardware Timer. PWM channel interval can be very long (ulong microsecs / millisecs). The most important feature is they're ISR-based PWM channels, supporting lower PWM frequencies with suitable accuracy. Their executions are not blocked by bad-behaving functions or tasks. This important feature is absolutely necessary for mission-critical tasks. These ISR-based PWMs, still work even if other software functions are blocking. Moreover, they are much more precise (certainly depending on clock frequency accuracy) than other software-based PWM using millis() or micros(). That's necessary if you need to control devices requiring high precision. Now you can change the PWM settings on-the-fly.
Language:C 0This library enables you to use Interrupt from Hardware Timers on Arduino AVRDx-based boards (AVR128Dx, AVR64Dx, AVR32Dx, etc.) using DxCore. These AVRDx Hardware Timers, using Interrupt, still work even if other functions are blocking. Moreover, they are much more precise (certainly depending on clock frequency accuracy) than other software timers using millis() or micros(). That is mandatory if you need to measure some data requiring better accuracy. It now supports 16 ISR-based Timers, while consuming only 1 Hardware Timer. Timers interval is very long (ulong millisecs). The most important feature is they are ISR-based Timers. Therefore, their executions are not blocked by bad-behaving functions or tasks. This important feature is absolutely necessary for mission-critical tasks
