Obviously there is no 0ms write time but to the application there would be. The part writes at the bus speed so you can in essence write the data as fast as the bus speed without any need to delay. ...

Nope, it is not the same. A FRAM has a program cycle time of 0ms.
There is no such thing as a program cycle time of 0ms. Looking at a popular manufacturer (Ramtron), their parallel FRAM modules hav ...

Here's a slightly modified and updated version:

I actually just whipped up my own font based upon the format presented here: http://instruct1.cit.cornell.edu/courses/ee476/video/Video32v2.c It is a drop in replacement for glcd_text57 called glcd_t ...

Hey All,

I've been working with a graphical LCD and tinkering with the GLCD.c driver. Is anyone familar with a smaller font (like 3x5 or 4x6) that can be easily integrated with the GLCD driver? T ...

However, nothing is being received.
Can someone please tell me:
(a) if I can use printf command for serial communication?

How to use Internal RC*4 ????????????See section 2.4.2 of the 18F6722 datasheet.

Have you checked your while loop in the function?
do{
old=x;
x=x-((a*x*x) + b*x + c)/( 2*a*x + b);
}while(abs((x-old)/x*100) ...

Wires were soldered onto the legs of the chip, then heatshrunk.Were they just heatshrunk or did you use adhesive-lined waterproof heatshrink?

Please let me know if I still miss something
You are missing the fact that the software RS232 code can not receive data unless the microcontroller is actively looking for it during the getc routine. ...

Just change this:
void lcd_gotoxy(int8 x, int8 y)
{
int8 address;

if(y != 1)
address = lcd_line_two;
else
address=0;

address += x-1;
lcd_send_byte(0, 0x80 | ...
