Display by Nokia 5110

Posted by: Alvin Jin , March 15, 2014

[vc_row][vc_column][vc_column_text]I ported NOKia5110 program to pcDuino, by using IO simulation to achieve., but I2C protocol is also possible, in this version has not been achieved. A total of three files LCD5110.cpp LCD5110.h LCD5110_Test.c, using c_environment routine.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column width=”1/1″][vc_tour][vc_tab title=”LCD5110.cpp” tab_id=”1394878312-1-61″][vc_column_text]
