Bresser 5-in-1/6-in-1/7-in-1 868 MHz Weather Sensor Radio Receiver for Arduino based on CC1101, SX1276/RFM95W, SX1262 or LR1121

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 freq…

This library enables you to use SPI SD cards with RP2040-based boards such as Nano_RP2040_Connect, RASPBERRY_PI_PICO using either RP2040 Arduino-mbed or arduino-pico core. This SD-Fat v2 can support FAT16, FAT32, exFAT file systems. exFAT supports files larger than 4GB by using uint64_t as file offset.

This library enables you to use Interrupt from Hardware Timers on RP2040-based boards such as RASPBERRY_PI_PICO. These 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 m…

This 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.
