hello everyone....

here's the final code that works for my MAX7318 Switch and LED application....

void see_switch()
{
while ( 1 )
{
i2c_start( ...

by the way, here is the schematic diagram...i hope this link works....

thanks, PCM Programmer....

i already tried that one but it's not working on my case. that would have made things quite easier....i don't know what is wrong but it just won't work. Crying or Very sad

are the ...

it worked! Very Happy

here is the final code that can successfully display the bytes (in read mode) of MAX7318 in the LCD display.

byte setme[5]={0xFE,0xFD,0xFB,0xF ...

really? how come i can't compile a simple code as that? Crying or Very sad

it always halts with the same error..

by read-only you do mean that everything is lost on a power failure, am i right? but i n ...

sorry for the delayed response...

i will try that code right away, sir Very Happy

and be back in a few minutes with good news, i hope Very Happy

thank you very much.

tried inserting that line:

#device *=16

but still can't create a 2x50-sized array...

how about migrating the code to some PIC18 chip? would that be too troublesome or not at all.............? ...

ooops....

i think i have a little problem posting my scanned schematic diagram....

sorry but how do i post a JPEG picture in this forum?

really sorry....the "insert image" did not w ...

tried that a few minutes ago...

i created two separate programs. here are the results:

the MAX7318 of the LED is working fine. i can successfully write to it as to which LEDs will be turned ON o ...

i2c_start();
I noticed another problem. These MAX7318 chips power-up with all
the i/o pins configured as input pins. You have to write to a config
register, to turn them into output pins. You ...

On the 16 chips, arrays _must_ fit into a single bank. On the 16F877, there are no 'full size' banks. Instead, it has 96 bytes in the first bank, 80 bytes in the second, and 96 bytes each, in the thir ...

i have a simple question.....

how can i create a 10x10 byte matrix? my compiler does not allow me to create an array with that size and instead goes into error that says:

NOT ENOUGH RAM AVAILA ...

in our project we used a TCXO from Maxim which is the DS32kHz. perhaps you are only using an ordinary crystal oscillator which may not be stable at all times. the DS32kHz is temperature-compensated so ...

Here are the pin connections:

APPLICATION TYPE SLAVE ADDRESS AD0 AD1 AD2

LED indicator output 0x32 SDA SCL GND

Switch input 0xA0 ...

edited the code with a few modifications...

BYTE byte1, byte2;
do
{
i2c_start();
i2c_write(0xA0);
i2c_write(0x02);
i2c_start(); ...
