I have a BS2p40 conecting with MAX6955 into pin 6 (SDA) and Pin7 (SCL) and
the MAX6955 have adress 00 (%11000000 (write) or %11000001 (read)). then,
in fact, i put AD0 and AD1 to gnd.... I don't know, why don't my Bs2p40
conect to MAX6955? When I try to read, in the variable, you can see
%11111111 and I sure that my parallax isn't write the MAX6955, because I
tried to put MAX6955 in Dysplay TEST.. ANd I don't know, What is the
Problem?
THe MAX6955 is the 2-wire, 2,7V to 5.5V LED DISPLAY DRIVER with I/O
Expander and Key Scan.. This is the new chip to MAXIM...
Anyone, help me?
