Raspberry Pi Pico Clock Shields

This is a collection of very versatile clocks due to its different feature sets and sizes, the RGB capabilities and additional buttons and sensors. Nearly all displays comes with a special LED controller wired over GPIO or other standard serial buses up to the Raspberry Pi Pico. Additional momentary push buttons or joysticks and a small buzzer are wired up over simple GPIO lines. Some shield provide also a simple temperature sensor or Real-Time-Clock, mostly wired over a dedicated I2C bus.

Utilization

This shields can be used with any development board, shield, or snippet that provides a Devicetree node with the raspberrypi,pico-header-r3 property for the compatibility. In particular, the I2C1 bus on pins 9 to 10 and some GPIO signals on pins 4 to 5, 14 to 22, 24 and 29 of this edge connector must be free for communication with the buttons, buzzer, LEDs, RTC and sensors on the shields. The ADC channel 0 on pin 31 must also be free for communication with the on-shield LDR (photoresistor). The shields also provide the special Devicetree labels &rpipico_i2c_rtc, &clock_rtc, &rpipico_pwm_buzzers and &clock_buzzer for this purpose.
