MIKROE 10x10 RGB Click is a matrix of 100 "intelligent" RGB elements, forming a 10x10 display screen. These LED elements feature internal logic, which allows them to communicate directly with the MCU. These intelligent LEDs are meant to be cascaded: the elements communicate by a single line with the host MCU and they feature a signal reshaping section, so the data gets to the adjacent element with no losses or distortion.
10x10 RGB Click is supported by a mikroSDK compliant library, which includes functions that simplify software development.
The WS2812 is an intelligent control LED light source, its exterior adopts the latest MOLDING packaging technology, the control circuit and RGB chips are integrated in a package of 2020 component. Its internal includes intelligent digital port data latch and signal reshaping amplification drive circuit. Also include a precision internal oscillator and a voltage programmable constant current control part, effectively ensuring the pixel point light colour height consistent.
The data transfer protocol use single NZR communication mode. After the pixel power-on reset, the DIN port receive data from controller, the first pixel collect initial 24bit data then sent to the internal data latch, the other data which reshaping by the internal signal reshaping amplification circuit sent to the next cascade pixel through the DO port. After transmission for each pixel, the signal to reduce 24bit. pixel adopt auto reshaping transmit technology, making the pixel cascade number is not limited the signal transmission, only depend on the speed of signal transmission.
RESET time >280μs , it won't cause wrong reset while interruption, it supports the lower frequency and inexpensive MCU.
Refresh Frequency updates to 2KHz, Low Frame Frequency and No Flicker appear in HD Video Camera, it improve excellent display effect.
LED with low driving voltage, environmental protection and energy saving, high brightness, large scattering angle, good consistency, low power, long life and other advantages. The control chip integrated in LED above becoming more simple circuit, small volume, convenient installation. 10x10 RGB Click can be used in many applications, like full-colour module, full colour soft lights a lamp strip, LED decorative lighting, indoor/outdoor LED irregular screen, game machine and amusement equipment etc.
The INT pin of the mikroBUS™, which is labelled as DO on this Click board™, allows cascading of multiple 10x10 RGB click devices. It simply routes the data line back to the mikroBUS™, allowing it to be re-used for the next 10x10 RGB click, and so on. The length of the whole chain is limited only by the communication speed, required to scan through all the LED devices, in order to maintain a reasonable refresh speed.
This Click board™ is designed to be operated only with 5V logic level. A proper logic voltage level conversion should be performed before the Click board™ is used with MCUs with logic levels of 3V3.
