Eos 400d ( Rebel XTI )

Kekk_400D

Hi,
first of all thanks for all your work for this magic sw.
I got a lot of problems with the latest version, the camera locked a lot of time and was forced to do a battery pull each time there was a lock. Moreover the camera locked when I mounted the flash Nissin, it has been impossible to shot with the flash.
I reinstall an old version of last year, suitable for my needs.

Well, I just returned from a 4 day trip with a full 2GB card, and guess what? The camera did not lock, not even once! And all I changed was these two lines at the end of [tt]display_overlay[/tt]:

void display_overlay(uint8_t *vram_address) {
    char buffer[LP_MAX_WORD];

    if (FLAG_GUI_MODE == GUIMODE_OLC && AE_IS_CREATIVE(DPData.ae)) {
        int current_cmode = get_current_cmode();

        if (status.msm_active)
            bmp_printf(vram_address, FONT(FONT_SMALL, COLOR_BLACK, COLOR_GRAY),  35,  96, "[***]");
        else if (status.cmode_active && current_cmode != CMODE_NONE)
            bmp_printf(vram_address, FONT(FONT_SMALL, COLOR_BLACK, COLOR_GRAY),  16,  96, "%s", cmodes_config.names[current_cmode]);

        if (status.fexp && DPData.tv_val != TV_VAL_BULB)
            bmp_printf(vram_address, FONT(FONT_SMALL, COLOR_BLACK, COLOR_GRAY), 138,  32, "#");

        if (settings.autoiso_enable && (DPData.ae != AE_MODE_M || DPData.tv_val != TV_VAL_BULB))
            bmp_printf(vram_address, FONT(FONT_SMALL, COLOR_BLACK, COLOR_GRAY), 237,  14, "%s", AUTOISO_AUTO);

        if (DPData.wb == WB_MODE_COLORTEMP)
            bmp_printf(vram_address, FONT(FONT_SMALL, COLOR_BLACK, COLOR_GRAY),  50, 138, "%d", DPData.color_temp);

        if (DPData.ae_bkt) {
            ec_print(buffer, DPData.ae_bkt);
            bmp_printf(vram_address, FONT(FONT_SMALL, COLOR_BLACK, COLOR_GRAY), 224,  96, "%s", buffer);
        }

#ifdef RELEASE
        bmp_printf(vram_address, FONT(FONT_SMALL, COLOR_BLACK, COLOR_BLUE), 148, 0, LP_WORD(L_P_400PLUS));
#else
        bmp_printf(vram_address, FONT(FONT_SMALL, COLOR_BLACK, COLOR_RED ),  20, 0, LP_WORD(L_A_WARNING));
#endif

        if (*display_message) {
            if(timestamp() < message_timeout)
                bmp_printf(vram_address, FONT(FONT_SMALL, COLOR_WHITE, COLOR_BLACK),  16, 228, display_message);
            else
                *display_message = '\0';
        }

enqueue_action() is calling TryPostMessageQueue() only.
IMO TryPostMessageQueue() should not be a blocking function, which means this 2 lines adds only few ns (or ms) delay to the display_overlay() routine.
Can you try it with SleepTask(10) for example.

Sergei

Eduperez, try to declare display_message as static variable in display.c.

static char display_message[LP_MAX_WORD];

Same here... (400D incl. BG-E3)

Many thanks for your great work! 😀

I have finally changed [tt]display_overlay[/tt] to this:

void display_overlay(uint8_t *vram_address) {
	char buffer[LP_MAX_WORD];

	if (FLAG_GUI_MODE == GUIMODE_OLC && AE_IS_CREATIVE(DPData.ae)) {
		if (FLAG_DISPLAY_ON) {
			int current_cmode = get_current_cmode();

			if (status.msm_active)
				bmp_printf(vram_address, FONT(FONT_SMALL, COLOR_BLACK, COLOR_GRAY),  35,  96, "[***]");
			else if (status.cmode_active && current_cmode != CMODE_NONE)
				bmp_printf(vram_address, FONT(FONT_SMALL, COLOR_BLACK, COLOR_GRAY),  16,  96, "%s", cmodes_config.names[current_cmode]);

			if (status.fexp && DPData.tv_val != TV_VAL_BULB)
				bmp_printf(vram_address, FONT(FONT_SMALL, COLOR_BLACK, COLOR_GRAY), 138,  32, "#");

			if (settings.autoiso_enable && (DPData.ae != AE_MODE_M || DPData.tv_val != TV_VAL_BULB))
				bmp_printf(vram_address, FONT(FONT_SMALL, COLOR_BLACK, COLOR_GRAY), 237,  14, "%s", AUTOISO_AUTO);

			if (DPData.wb == WB_MODE_COLORTEMP)
				bmp_printf(vram_address, FONT(FONT_SMALL, COLOR_BLACK, COLOR_GRAY),  50, 138, "%d", DPData.color_temp);

			if (DPData.ae_bkt) {
				ec_print(buffer, DPData.ae_bkt);
				bmp_printf(vram_address, FONT(FONT_SMALL, COLOR_BLACK, COLOR_GRAY), 224,  96, "%s", buffer);
			}

#ifdef RELEASE
			bmp_printf(vram_address, FONT(FONT_SMALL, COLOR_BLACK, COLOR_BLUE), 148, 0, LP_WORD(L_P_400PLUS));
#else
			bmp_printf(vram_address, FONT(FONT_SMALL, COLOR_BLACK, COLOR_RED ),  20, 0, LP_WORD(L_A_WARNING));
#endif

			if (*display_message) {
				if(timestamp() < message_timeout)
					bmp_printf(vram_address, FONT(FONT_SMALL, COLOR_WHITE, COLOR_BLACK),  16, 228, display_message);
				else
					*display_message = '\0';
			}
		} else {
			SleepTask(OVERLAY_DELAY);
		}
	}
}

And this seems to be working properly; so I have just released it as 20130414-03.

Many thanks for your help!

eduperez

It has been reported to me that version 20130414-03 still produces camera lock-ups; and unfortunately, I do not have much time right now to spend on this. I have just released 20130414-04, that disables all the overlay information, until I can find some time and come back to this issue.

Hi,

most likely you've already heard about this: http://haxit.blogspot.ch/2013/08/hacking-transcend-wifi-sd-cards.html

He managed to hack a wifi sd-card that is based on a linux system. So I thought that maybe by using a Sd2CF Adapter card this would offer a whole bunch of possibilities by accessing the linux system on the sd wifi from 400plus. I've ordered a Transcend wifi to see if the already existing 400plus is working with it

Regards
F.

Many thanks for the link. I had not read about that hack before, and it looks very interesting: with the proper software, it could allow us to upload files (our AUTOEXEC.BIN mostly) directly to the card, without having to remove it from the camera, before each test. I'm waiting for your results!

Yeah, pretty cool, please report your results.

me noobie.

I just picked up an XTi used off some bloke. A major upgrade over my first-gen rebel. Naturally, the first thing I do is hack it. Now I'm running 400plus and interested in learning how to write scripts for it. Are LUA scripts compatible with 400plus? Are there other languages I can code them in? My familiarity with LUA is basic, to say the least, but I have a solid understanding of C-derivative and markup languages.

Point me in the right direction. I want to sink my teeth into this one while the novelty is fresh.

There is no scripting language in 400Plus.
The only way to write your own automation is to get the source code and write it in C, then compile and run.
You will need to understand the 400Plus API and Canon API for this. Not so hard to learn.
There is no other option ATM.

Okay... I picked up a book on ANSI C. I downloaded a source package, and I'm thumbing through screens of code. I installed Pelles C IDE, but it sounds like I might need to run a virtual machine to compile this thing. Is that right?

I think there is a compiler for win32, but we are using linux.
To start with development you can refer to these articles:
https://code.google.com/p/400plus/wiki/devinfo
http://www.magiclantern.fm/forum/index.php?topic=991.0
If you read the ML info, keep in mind that you need our source code. No need to checkout ML source code.

So far so good! I found that the 'menu' files were the best place to start / the simplest place to find a link to what I see coded and what I see on my camera screen. Found all the undocumented navigational features. That was fun. Discovered the markdown file this morning, which helped to clarify some things. Now I'm scanning header files for useful constants and functions, daydreaming, watching clouds go by, brainstorming.

Hi all,

the card arrived. I can confirm that 400plus runs from this card 😁 I am using a 'delock sd to cf adapter' (just google it, it is a yellow adapter) and after making the card bootable using EOScard (running under Win😎 and transfering/copying the 400plus files from an existing card things worked again. Now I can access my photos from my iPhone/iPad etc. For a list of features have a look at the transcend card docu.

I can also see the Autoexec.bin etc. in the files section using a browser but by default there is no way to upload files from the PC (at least I didn't find it yet).

Maybe I'll try to get an ftp server up&running after hacking the card. My skills maybe too limited for this though.

This is cool.
It's pretty important for us, to be able to upload files to the card. Please report if you succeed.
BTW what's the total price for the card and the adapter (reference price)

Hi.

😁 😁 😁 😁 !!!!!! Success !!!!!! 😁 😁 😁 😁

In fact it is soooo easy (though it took me a while to realize)

After following http://haxit.blogspot.de/2013/08/hacking-transcend-wifi-sd-cards.html with installing chrome in my linux-vm trying and all the other stuff described on this site for several hours I realized that you only have to do this:

Create a script (named autorun.sh) in the root of the SD card (did this using Win8 & Notepad++, Windows users be aware: some editors may have problems creating LINUX conform linefeeds)
copy the busybox-armv5l binary (download link is given on the site) also to the root of the SD

autorun.sh

cp /mnt/sd/busybox-armv5l /sbin/busybox
chmod a+x /sbin/busybox
/sbin/busybox telnetd -l /bin/bash &
/sbin/busybox tcpsvd 0.0.0.0 21 ftpd -w / &

(Change / to /mnt/sd in the last line in case you only want access the 'normal' CF-card area instead of the linux system running on the SD card)

Now you can either telnet (telnet 192.168.11.254 that's the SD cards default IP) into the SD-card or transfer files via ftp (tested up-/downloading using Firefox & FireFTP addon)

The cool thing is if you can create files via 400plus (e.g. just an empty file in any subdirectory) you could have a simple bash script watching for the existence of this file and execute another script (e.g. for transferring your pictures to a NAS, etc.) You may think of very fancy stuff as with this SD card you have another computer running in your camera. As somebody commented on the original hack site

Amazing!!
16/32GB flash, 32MB RAM, 400+ BogoMIPS processor, wifi connectivity...inside a SD card!!

Regards

BTW SD card was ~50€ incl. shipping via eBay, I already owned the Sd to CF Adapter but you should get one for ~20€
