I recieved some very good help form jonathan.  He sent me this information to talk to the Max chip form (i believe) a pic.
 

Init_Display:
i2cout dispSDA,dispSCL,dispDev,$01,[$FF,$FF] ' Set Intensity
i2cout dispSDA,dispSCL,dispDev,$03,[$01] ' Show all 4 chars
i2cout dispSDA,dispSCL,dispDev,$04,[%00001001]' Config Byte
i2cout dispSDA,dispSCL,dispDev,$60,[" "," "," "," "]' Clear display
i2cout dispSDA,dispSCL,dispDev,$60,["INIT"]',fail
pause 1000
i2cout dispSDA,dispSCL,dispDev,$60,[" "," "," "," "]' Clear display

Note that line 5 is the one that displays the word "INIT" using the internal font. Lines 1 -3 init the display. 

Hope this helps. If you have any other questions, mail directly to jpeakall@madlabs.info, I will respond faster that way.

So i wrote mine like this.

 

 


[code]
Start: 
' Max6953 I2C Initialization 
I2CStart SDA 'Set Intensity 
I2CSend SDA, TopSlaveID 'Addresses the top Max Chip 
I2CSend SDA, $01 
I2CSend SDA, [$FF,$FF] 
I2CStop SDA 
I2CStart SDA 'Show all 4 characters 
I2CSend SDA, TopSlaveID 
I2CSend SDA, $03 
I2CSend SDA, $01 
I2CStop SDA 
I2CStart SDA 'Config Byte 
I2CSend SDA, TopSlaveID 
I2CSend SDA, $04 
I2CSend SDA, %00001001 
I2CStop SDA 
I2CStart SDA 'Clear Screen 
I2CSend SDA, $60 
I2CSend SDA, [" "," "," "," "] 
I2CStop SDA 
[/code]

 

I cant get past the 



[code]
I2CSend SDA, [$FF,$FF]  
[/code]
in the debug window.  Is i because i need to do a seperate entry for each item.  ie..
 

'

[code]
Max6953 I2C Initialization 
I2CStart SDA 'Set Intensity 
I2CSend SDA, TopSlaveID 'Addresses the top Max Chip 
I2CSend SDA, $01 
I2CSend SDA, $FF 
I2CSend SDA, $FF 
I2CStop SDA  
[/code]
Will that make it work and does it mean the same thing as the samlpe pic code sent to me?
