Never mind I've found the problem. The slave address in the control byte I send is supposed to be A8, AA, AC or AE depending on which device on the Bus I want to read or write. I hope this can help so ...

Hi again,

I'm testing with a futurlec board ET-MINI 24xx serial EEPROM. The EEPROM chips are 24LC32A. I use the provided 2432.c driver provided with CCS compiler version 4.104 but I have trouble wi ...

Thank you for this driver PCM Programmer, this helped me alot.

Sorry to bump this tread.

I think i've figured out how to put into 12 hour mode like so:

#define BIT_VAL(x) (1 << x)

void ds1307_set_date_time(BYTE day, BYTE mth, ...

Now i'm trying to figure out side scrolling on a single line but i haven't got any luck yet.

This is the code i'm trying:

int8 i;

LCD_Position(1,1);
LCD_ClearDisplay();
d ...

Here's a library i found and modified for an 4x20 LCD

It surely need improvements but it does the job nonetheless.

I Hope it will be helpful to someone ...

This is a little code i've did at the college. The function is simple; read a 4x4 keypad which is polled by an interrupt on RB2. The code can read a password from EEPROM and compare it to a user input ...

Whose 'serial 4x20 LCD' ??????

He may have this lcd:

Or, he may have this adapter:

Well the display itself is Parallel but i use a serial lcd controller to interface it to the PIC. I know the basics but is can be quit time consuming to type everything, that's why i asked for a drive ...

I've checked the product number and i've came up with this:
CFAH2004A-YYH-JP#

The serial LCD controller is from MELABS

Last question, is there a driver for serial LCD 4x20?

It seems i did not explain myself properly, so let me try this again.

The code is working fine except for one thing, if i press a key for too long, it increments my variable inputCount from 1 to 4. ...

Yes I saw this code before, its not really what I'm looking for though. I prefer using array, this way I can read easily read from EEPROM and reduce to a minimum the length of the code.

Hi,

I'm trying to interface a 4x4 keypad with interrupts. Here's my issue. I want to verify which key is pressed an put them into an array to later compare that array with a pre defined password. ...
