Display 7 Segments Different This 7-segment display, model TOD-5202PBG-B28/BS4, has two digits and 8 multiplexed pins. Does anyone know what style of multiplexing this is? I couldn't find its datasheet, so I made a truth table of the segment activations and used it to build this circuit. Pins 1 to 4 only accept 0V, while pins 5 to 8 only activate with +Vcc (5Vdc). Can anyone program a counter from 00 to 99 using a PIC16F628A, for example, and this display? Esse display de 7 segmentos modelo TOD-5202PBG-B28/BS4 tem dois dígitos e 8 pinos multiplexado. Alguém sabe que estilo é essa de multiplexação? Eu não consegui achar o seu datasheet, então fiz a tabela verdade de acionamentos de seus segmentos e através dela fiz esse circuito. Os pinos de 1 a 4 só aceita 0v, enquanto os pinos de 5 a 8 só aceiona com +vcc( 5Vdc). Alguém consegue programar um contador de 00 a 99 usando um pic16f628A por exemplo e esse display?
