rmptxf/NeoController
A project that uses the nRF52 to control a neopixel (ws2812b) over BLE using a custom mobile app built using the ionic framework.
khoih-prog/nRF52_PWM
This library enables you to use Hardware-based PWM channels on nRF52-based boards to create and output PWM to pins. Using the same functions as other FastPWM libraries to enable you to port PWM code easily between platforms.
patrickmoffitt/zephyr_ble_sensor
Bluetooth Low Energy Environmental Sensor for Adafruit nRF52840 Express and Adafruit BME680.
jeff-winn/nemesis-mod
Just a little project to mod a Nerf blaster with Arduino compatible hardware and Bluetooth support.
khoih-prog/nRF52_Slow_PWM
This library enables you to use ISR-based PWM channels on an nRF52-based board using Adafruit_nRF52_Arduino core such as Itsy-Bitsy nRF52840 to create and output PWM any GPIO pin. It now supports 16 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
