I did a quick try this morning
Eeprom page 0 shows all F's so I did an [Upload] and then I hit [change]
The eeprom page0 still showed F's. I tried a few different ways in one case
just upload without change. You mention "SAVE CHANGE" is this the [change]
button once uploaded. I then deleted the F's then hit [change] page still
filled with F's.
I will take another look tonight and upload your "sample.bin" file just in
case mine is corrupted.
Questions:
1) My BAE0910 is hanging off a hobbyboards hub. I assume this is OK.
2) I assume once its uploaded that EEprom Page0 will show something else
other than F's.

Hi,
from owhttpd, select eeprom/page.0, upload the generated file and save
change.
You may need to erase the page if it already content some data.
You may also copy your generated file rob.bin to eeprom/page.0 (via fuse
file system) from the shell or within the makefile.

Pascal,
I got flex and Bison installed OK on ubuntu hardy
Test file, "thought I would start simple and just set a user register"
#include "bae0910.inc" // may contains a path
#eeprom 0, 0 // start_page, end_page
#org $00
begin:
NOP
init:
SET.B B_USERA,100
Output generated by ae_asm, I assume it compiled without errors and the
installation of packages is OK
<mailto:r...@xxxxxx> r...@xxxxxx# ../ae_asm -o rob.bin ./reef1.asm
processing file ./reef1.asm - pass 1,
processing file ./reef1.asm - pass 2,
Code start at :0x0000
Code end at :0x0004
Size reserved :0x0200
Symbol Table :
begin LABEL 0x0000
init LABEL 0x0001
ouptut to rob.bin
<mailto:r...@xxxxxx> r...@xxxxxx#
Now where within owhttp pages do I upload the generated AE bin file to the
slave. There are too many choices for the uninitiated.
owhttp provides upload/browse for
command:
memory:
eeprom:

Hi Rob,
my reply in text.

Hi Pascal
I am not sure if I should use this forum for BAE0910 assistance however it
might be good for others setting up the device.
I think It is not a problem, but if It's not related to OWFS, you may also
post in the brain4home forum
<http://www.brain4home.eu/index.php?option=com_agora&Itemid=2> .
I have two of the slaves connected to the futurlec 4 channel relay boards.
I did a quick mod on a couple of channels and simply replaced the relay with
a FET. Simple process, didn't have to cut any tracks just two simple
links. I have used the BAEo0910 4 outputs -Out, pwm1, pwm2 and PIO. I have
managed to switch each output and setup the PWM for a small fan by setting
the parameters through owhttp. So I have proven I can drive the 4 channels
and now have to setup the AE so I can prelaod some values on startup.
Good...
Some questions
1) If I use the PWM as a pure output do you have any recommended PERIOD /
TMPxC settings, does it matter ?. I see setting dutyx to either 0 or
>period toggles the output on/off.
This not really matter. But note that the state change when the internal
counters are crossing limits, so if set very slow (down to 2Hz) , you may
encounter up to 500ms delay when toggling state.
2) I tried to install the ae engine on Ubuntu. It failed as I think it
needed some pre-requisites. I tried an apt-get for flex and bison as I
assumed I needed these however apt-get could not auto find these so I will
do some more homework on this and manually download them. Are these the
only two programs I required before I install ae_asm ? Is it version
specific for flex / bison ?
I installed AE in both ubuntu(9.04) and debian (lenny) with standard flex &
bison packages from distributions.
strange that you don't find the packages within the standard repository.
I simply did:
apt-get install flex
apt-get install bison
apt-get install build-essential
I think that not other package are required, but I will test this on as
fresh ubuntu 9.10 to confirm.
3) Can you help on PIOC, If I use this as an output what does the PD
actually do ?
When set as output, the pin follow PIO value regardless of PE & PD values.
1: pin is held up (to vcc) and thus could drain current up to 20mA
(effectively 10mA due to the 470R resistor)
0: pin is held down (to gnd) and thus could sink current up to 20mA (10mA).
