Request/Problem:
i am trying to use this chip with Bs2p40 of PARALLAX, I don't have problem
to comunicate and configurate this chip by I2C, But I have a problem with
Display... Because, I am trying to use this chip with sixteen (16)
7-segment and each of segment is construcction by me by four (4) led
(Vd=0,8Vdc)... When a put in the MAX6955 this display.. I don't see
anywere, but If i put only two (2) led per segment I can see the
numbers..... I don't understand this because I can see in your datasheet
that if possible to put segment od (Vd max =V+ - 0,8)... Can you help me
about this requierement, I need to put this plataform in funtion with four
(4) led per segment...
I appreciate your prompt response
