Seven-segment displays are controlled by additional drivers and their intensity is adjustable by a potentiometer on the back panel. Chassis was custom made by SSI Schäfer, s.r.o. \u003cbr\u003e\nAll Cirucit Boards are single-side printed: \u003cbr\u003e\nLK01-16 - The seven-segment dispalys. \u003cbr\u003e\nLK02-16 - The main board embeding microcontroller i8051 and Epson real-time chip \u003cb\u003eRTC72421\u003c/b\u003e\u003cbr\u003e\nLK03-16 - The board contains switches for time setting and a potentiometer for adjusting brigthness of the dispaly.\n\n\u003cb\u003eSoftware\u003c/b\u003e\nSoftware is developed in an assembly language for Intel microcontrolers series i8051/MSC-51. \nInsturction set and manuals are available at: \u003ca href='http://web.mit.edu/6.115/www/document/8051.pdf'\u003e http://web.mit.edu/6.115/www/document/8051.pdf \u003c/a\u003e\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fkopeckylukas%2Fdigital-clock-lkdesign","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fkopeckylukas%2Fdigital-clock-lkdesign","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fkopeckylukas%2Fdigital-clock-lkdesign/lists"}
