Hi,

The clock is working now, but every time I restart the PIC, the seconds starts from Zero.

How do we avoid this.

Thank You

Hi Dany,

Many Thanks for the suggestion.

It is working fine now.

Thank You

Hi, I have defined an array as following unsigned char output[2]; when I use Lcd_Out (1, 10, output); The characters gets displayed at 1,10 correctly, but I get unknown characters on other parts of the LCD. If I do Lcd_Chr (1, 10, output[0]); Lcd_Chr 91, 11, output[1]); then all works as expected. A...

Hi,

I have downloaded the examples and checked. Please note, i am able to set the time in DS1307 as well as read from it, but the clock is not incrementing itself

Do we need to initialize the DS1307?

How do we set the DS1307 to count in 24hour format?

Thank You
Shankar

Hi,

I am able to set and read the time and date from the DS1307.

However the DS1307 is not updating the time.

Is there any setting to be done before the DS1307 starts running.

Thank You
Shankar

Hi,

Tried the suggestion, no improvement.

Please help.

Thank You.

Hi, I have interfaced LCD jhd629-204a with PIC 16F877A. The characters appear very dim and is hardly visible. What could be reason? Pin 1 - Not Connected Pin 2 - +5V Pin 3 - Not Connected Pin 4 - Pin 35 of PIC (RB2) Pin 5 - Gnd Pin 6 - Pin 36 of PIC (RB3) Pin 7,8,9,10 - Gnd Pin 11,12,13,14 - Pin 37,...

Hi, I am new to PIC and electronic design. Is it possible for any body on the forum to share the basic circuit for a PIC16F877A. ie 1. How to power the PIC. 2. How to protect the PIC from intereference. 3. How to use decoupling. If anybody can share any time tested circuit, it will be of great help....

Hi,

Any example on indirect addressing of a particular element in an array is going to make my understanding faster.

Hi Mince, Thank You for the Great Advice on reducing RAM usage. I could reduce the RAM usage to 37% as of now. "work smarter not harder" - Comes from experience I guess. Just for enhancing my knowledge, how do I access the BANK 3 and 4 w.r.t arrays. If you give some reference it will of immense help...

Hi Mince,

Thank you for your continued guidance.

1. What is RWM errors.

Will all ports of PIC16F877A have this problem?

2. Does PIC18 have MSSP ports to work with I2C devices.

Thank You
Shankar

Hi Alexander,

Since accessing Bank 3 or 4 seems unevitable, please for understanding purpose could you please explain how to use indirect addressing for accessing a particular element of an array.

Thank You

Hi Mince, The output from the HEX code is not displaying correct values. This display is the same as which I get when I run the HEX file generated from my system with the IRP Message as a warning. I have send the full project file to your email id. Please check when you get time. Thank you for the e...

Hi Mince,

I have done that too.

Looking forward to the HEX file from you.

Thanks
Shankar

Hi,

I am running the full version.

My install shows ver as 3.2 even though the patch 3.21 was installed.

Where could be the problem.
