Overview
2024.03.15 AVR SCORE BOARD TX v2 is an open-source printed circuit board by jarwyg, from the jarwyg/WS2811_SCORE_BOARD repository on GitHub, published under the MIT licence. It is a 2-layer board with 47 parts on 54 nets, routed with 516 tracks and 38 vias.
It is built around the ATMEGA328P-PU, NRF24L01 and BC817. Its parts include 12 switches, 6 resistors, 5 capacitors, 5 ICs and 4 connectors. It belongs with the AVR (ATmega, ATtiny) boards of this library.

README
README.mdWS2811_SCORE_BOARD
W 2017 wraz z znajomym z roku stworzyliśmy tablicę wyników zbudowaną z wykorzystaniem pasków LED WS2811.
W 2024 projekt został ulepszony pod względem hardware oraz firmware. Aktualnie jest opublikownay jako open-source (MIT License)
Firmware
Firmware jest napisany w jęzku c. Projekt był stworzony w Eclipse z AVR plugin (kompilator avr-gcc). Katalog Release zawiera pliki makefile więc można projekt skompliować z poziomu terminala. Gotowe pliki binarne można znaleźć poniżej
Receiver
Odbiornik działa na mikrokontrolerze Atmega88/168/328 (16MHz - zawnętrzny oscylator). Czas jest brany z RTC PCF8563. Płytka powinna mieć wgrany bootloader z arduino UNO. Dzięki temu po podłączeniu przejściówki USB-UART łatwiej będzie wgrać aktualizację/zobaczyć debug podczas pracy układu. Tablica prawdopodobnie będzie w niedostępnym miejscu więc zalecam zostawienie długiego przewodu USB/RS232
PCB
Transmitter
Pilot działa na mikrokontrolerze Atmega88/168/328 (8MHz - wewnętrzny oscylator) Domyślnie jest w trybie uśpienia i pownien pobierać mniej niż 70uA. Komunikacja z odbiornikiem odbywa się tylko w jedną stronę.
