Hello,
it looks like you still have to discover Emacs and its frames, and
Makefile.
However, don't try it under Windoze, it looks ugly !

Hello Jason,
The 44780 driver has a RS (register select) line that tells whether the byte
(or nibble) is a command or a data (0 = commands, 1 = data). Commands control
the internal working of the chip, data are to be written in (or read from)
data memory and displayed as characters.
Your "lcd
You're right. I didn't read all the code. I just took "lcd_command" for a
"command" function, but it actually is a general "write" function.
Ten milliseconds still make a long E pulse. It's not the problem.
Maybe I have not read all the code, but I don't see where (when) the address
is written

You can use objcopy from GNU_binutils,

#!/bin/bash
# hex to bin
fichier=$1
objcopy -I ihex -O binary $1 ${fichier%.*}.bin

OBJCOPY= /your/path/to/objcopy

So, why not free some _data_ space (the default) by defining some variables
as _xdata_ ? You'll have to do that yourself.

Hi,
It looks like you don't think that the end-of-charge voltage is above the
nominal voltage.
On the schematics given in the link hereafter, it would be safer to put a
zener diode across the lower resistor of the divider, to protect the
controller.

Maarten is right.
You have to reset the bit EXTRAM in the AUXR register (0xA0) (not bit
addessable) in order to use internal "external" RAM.
By the way, my thanks too for the nice software.

to C. For each
update, I start a 486 PC running MSDOS and tell myself it's the last time ;-)
Thinking about retirement, I'll have to talk the customer into ordering the
conversion from me, if he ever wants maintenance by younger people he's been
hiring.

Hello Denny,
You could have a look at avr-gcc for Linux and cdk4avr (although you look like
using Windoze).

You are talking of problems I encounter when using Windows, be it with other
applications: it is sometimes unpredictable.
Are you sure you want to continue with Windows?

Hello Ivan,
The task you are describing is as simple as RA1 = !RB0.
To use interrupts in any controller (so in PICs too), you have several things
to configure:
- choose whether the interrupt routine will react to a state or to an edge;
- choose that an ISR will react at all, i.e. allow interrupt
Hello Gonzalo,
I'm using Flowcode (TM) for PIC's.
With SDCC, I program only 51's.
The purpose of my previous post was to give our friend Ivan, who says himself
new in microcontrollers, a first view over the working of interrupts in
general.
Now, thanks to you and your link, he'll have a closer
May I say that, although I'm using Gnome, I prefer portability by far?

Hi,
could it be that tmr has to be declared volatile?
Worth a try.
