Hi:

I can provide some help with the MAX7219 if this thread is still active.

I have used this chip in most of my 7 segment project since it is quite flexible.

Let me know

Hi:

I did some rewiring as I have found in the past that a particular type of 8 pin socket that seems to be the only kind I can get has caused me problems. I wired an 18Pin socket of the type I...

Hi Steve:

Thanks for the suggestions and the code. I am just building my proto type board, and so far, I have the LCD working and 2 dual segment 7 segment displays running off a MAX7219. That is...

Hi Steve:

Thanks for posting the code. How long should this take to complete? I can see that it is cycling through addresses 0 to $FFFF. I put in a line between the next and GOTO Start to light...

Hi Steve:

I am sitting here watching the program run on the ICD. I wish they went faster.

I will confirm that the...

Thanks Steve:

The data sheet for the EEPROM states that it is expecting the Address High...

Hi:

I have read through several posts on the forum regarding i2c, and I have read the information in the PBP manual.

I have used the following code:
ADDR var byte
ADDR = $07
