Dot matrix display using MAX 6953 & PIC 16F877A

[rinshadbasheer]

Hello Everybody,

I am new to embedded field. I am trying to design a dot matrix display using 4 units of 5*7 dot matrix's. I have chosen MAX 6953 for driving the matrix's and the controller I am using is PIC 16F877A. I have completed a simulation circuit in Proteus. I am using Hi Tech C for coding. I don't know the code for interfacing PIC 16F877A with MAX 6953. I didn't understood programming Idea from Application note of MAXIM. So please help me in coding. Full code is not necessary. I want to know how to send data to MAX6953 from PIC 16F877A or any controller with SPI interface.

The MAX6953 has a IIC (I2C) interface, the MAX6952 uses SPI.

Have a look at the Microchip application notes, there will be one for writing to I2C EEPROMs which you can modify for your needs. If I remember right, the MAX6953 required two bytes to be sent, one data and one control.

You are lucky Proteus has these display drivers, I used a 6952 in a project and it was before Proteus supported it .
