SD1100/ixus 80 porting ....

[fudgey]

Is get_mode in video mode broken for ixus80_sd1100 or does its video mode work differently from other cams?

I had modify the script you posted because the console disappers in Video and Play mode very quickly.

I ran it in all 3 modes and got as the result

No Video Button
Rec Mode in Rec Mode
Play Mode in Video and Play Mode

here is my version

Code: [Select]

@title modetest
print_screen 1
V=get_video_button
if V=0 then print "No video button."
if V=1 then print "Cam has video button."
M=get_mode
if M=0 then
print_screen 2
print "Rec mode."
endif
if M=1 then
print_screen 3
print "Play mode."
endif
if M=2 then
print_screen 4
print "Video mode."
endif
sleep 5000

Is this still being worked on? I'm so looking forward to autostart with >4gb cards.

Nope, you're out of luck. It appears that Chris looked into it, and included the necessary code in largedisk.c for FW 100c (but not for 101a), but this code doesn't seem to be used in the build. He apparently believed that he needed a large card to test it -- "This is not supported unless I receive a large SD card".

any success with the LED control for the sd1100is ?

i need to interface a motion detection script  to a microcontroller

i have tried several things in both LUA and BAS scripts (set_led)
but no success with the latest trunk

i have poked around and compiled some changes in the source
but  but no luck here either.

i can get a "beep"  but with the environment i need to use it in. noise is going to be an issue.

any ideas?

The specification of UBASIC set_led seems to be a little bit weird.
http://chdk.wikia.com/wiki/UBASIC/TutorialScratchpad
set_led a b c
a:4..10 = green, yellow, unused, orange, blue, AF beam, timer

Did you try something like this in platform\ixus80_sd1100\lib.c

Code: [Select]

void ubasic_set_led(int led, int state, int bright)
{
int leds[] = {0x134,0x138,0x134,0x130,0xd4,0x3030,0x3030};  //  green=4 | yellow | (not used) | orange | blue | af beam | timer
// if(led < 4 || led > 10 || led == 6)  //  map to valid params;  no extra TIMER LED (is same as AF)
volatile long *p=(void*)0xc0220000 + leds[(led-4)%sizeof(leds)];
if (state)
p[0]=0x46;
else
p[0]=0x44;
}

I don't own sd1100 - you have to try yourself ;-)
When it works, it should be added to the repository.

Can I set SD1100 to Macro using property values?
If so what numbers should I use?

According to http://chdk.wikia.com/wiki/Propertycase propcase 6 contains that value for digic III/IV, but is read only. You might want to try it anyway, I think I got the SD990 to use focus at infinity by setting this.

I tried it - it worked!
set_prop 6 1
turns SD1100 to Macro mode

[reyalp]

Have you checked to make sure it's actually in macro mode, not just displaying the icon in the UI ? If it is, then please add a note on the wiki. (I'm 99% sure I tested this and it worked fine on the SD990, but I don't have the camera any more, so I'm hesitant to do this without confirmation)

im still trying to gain control of "any" of the LED's on the SD1100is  from ubasic
no success so far.

how do i call the CHDK functions "LED_GREEN_ON /  OFF"  in leds.h leds.c
from ubasic ??

I have not followed this thread and do not have time to read it now, but if there is an led at 0xC0220134 the  following should turn it on/off :-

ubasic_set_led(4,0,100)
ubasic_set_led(4,1,100)

have been playing around with it for a while now.

and have not been able to get any of the ubasic or LUA Commands to work for
control of any of the LED's with the any of the stock firmwares

I have been doing alot of changes around in the code. 
and at last i have success
turns out that all that is needed is some changes to the code in
(trunk885) /platform/ixus80_sd1100/lib.c

i Forget where i found the code bit. and don't remember if i modified any of the LED addresses myself.
but i replaced the whole  "ubasic_set_led" function (which is all commented out) 
with this

Code: [Select]

void ubasic_set_led(int led, int state, int bright)

{
int leds[] = {0x134,0x138,0x134,0x130,0xd4,0x3030,0x3030};  //  green=4 | yellow | (not used) | orange | blue | af beam | timer
// if(led < 4 || led > 10 || led == 6)  //  map to valid params;  no extra TIMER LED (is same as AF)
volatile long *p=(void*)0xc0220000 + leds[(led-4)%sizeof(leds)];
if (state)
p[0]=0x46;
else
p[0]=0x44;
}
and i got the ubasic "set_led'"  command to work.  the following blinks the blue led

Code: [Select]

@title Test LED Script

sleep 500
print "blue on"
set_led 8 1 60
sleep 500
print "blue off"
set_led 8 0
end

finally i can use the motion detection scripts to trigger
"external hardware"
