khoih-prog / RP2040_PWM
This library enables you to use Hardware-based PWM channels on RP2040-based boards, such as Nano_RP2040_Connect, RASPBERRY_PI_PICO, with either Arduino-mbed (mbed_nano or mbed_rp2040) or arduino-pico core to create and output PWM any GPIO pin. The most important feature is they're purely hardware-based PWM channels, supporting very high PWM frequencies. Therefore, their executions are not blocked by bad-behaving functions or tasks. This important feature is absolutely necessary for mission-critical tasks. These hardware-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 ISR, millis() or micros(). That's necessary if you need to control devices requiring high precision. New efficient setPWM_manual function to facilitate waveform creation using PWM
Language:C++ 61This library enables you to use RTC from RP2040-based boards such as Nano_RP2040_Connect, RASPBERRY_PI_PICO. This RP2040-based RTC, using Interrupt, has no battery backup. Time will be lost when powered down. To need NTP-client to update RTC every start-up.
Language:C++ 22Wrapper of LittleFS for Arduino MBED RP2040 boards. This library facilitates your usage of LittleFS for the onboard flash. LittleFS supports power fail safety and high performance
Language:C++ 20This library enables you to use 1 Hardware Timer on RP2040-based board, such as Nano_RP2040_Connect, RASPBERRY_PI_PICO, to control up to 16 or more servo motors. Now permitting using servos with different pulse ranges simultaneously.
Language:C 16This library enables you to use Interrupt from Hardware Timers on RP2040-based boards such as Nano_RP2040_Connect, RASPBERRY_PI_PICO. These MBED_RPI_PICO_TimerInterrupt 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's 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're 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.
Language:C 10This library enables you to use Hardware Timers on RP2040-based RP2040 board to create and output PWM to pins. These PWM channels, using RP2040 Hardware-PWM channels, still work even if other functions are blocking. Moreover, they are much more precise (certainly depending on clock frequency accuracy) than other software ISR-based PWM, using millis(), micros() or Timer Interrupt. This important feature is absolutely necessary for mission-critical tasks. You can start, stop, change and restore the settings of any PWM channel on-the-fly
Language:C 3This library enables you to use ISR-based PWM channels on RP2040-based boards, such as Nano_RP2040_Connect, RASPBERRY_PI_PICO, with Arduino-mbed (mbed_nano or mbed_rp2040) core to create and output PWM any GPIO pin. 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
