It is something pleasantly cheap from China, bought at e***.comJustGreg:
@DmitriWould you be so kind as to name that battery pack on your picture? Thank you.
70mAh
Thx.
I was able to solve the problem myself: the reason came from a poor soldering of the camera on the board...gentlemich:
When reading the register (0x00 in this case) the I am getting the first Acknowledgement but not the second! Therefore nothing is happening and I cannot read the register.
I2C is ok and I even did not need any voltage translator (although the processor is at 3.3V the I2c line was limited at 3V by itself).
Here it is the new breakout version:
Can this (or any hobby camera) output raw (uncompressed) images?
My micro has limited space and a jpeg decoder doesn’t fit… I’d like to find a uart/spi camera that outputs 8-bits per pixel… (@320x240 resolution would be nice). Even monochrome 1bpp would be fine!
Hi all!
I’d like to make something clear. I cannot provide any assistance in building something similar nor I would sell a ready-to-use device.
The first is because my motivation for this has gone, the second is because of juristical reservations about unknown purpose.
The entire project is still on sale though.
@Dmitri: when you say the project is for sale, is it this one:

(I didn’t see any pricing info)

My thingie is this one viewtopic.php?p=109977#p109977
It runs at 24 frame per second storing 320x240 color pictures to the micro SD card.
A PC software is available to dump frames to the HDD.
Nice thingie.
How do I use my webcam to remotely view my puppies from work? I have my webcam set up at home. When I get to work I would like to use it to view my puppies. At one time I had a free program I logged in to to do this but have lost it in a crash. Any ideas how I can do this?

I’m starting to handle the camera TCM8230MD and I think this worked well, but I could see the data, someone can help me?
Hi all,
Boy that’s a lot of reading…
Shortly put: Has anyone had any luck with the camera MCU or FPGA???
Regards
Sure :wink:ugilten:

Check this about TCM8230MD:
Hello,
I’m having a problem with the TCM8230MD, I’ve read everything there’s to read, but still I’m not able to receive a whole frame, just 1/4 of a frame, this is my initialization based on the datasheet and some replies:
i2c_write(0x02, 0x80); /FPS = 15/
i2c_write(0x1E, 0x48); /CODESW off/
i2c_write(0x03, 0x22); /DOUT, subQCIF(8), RGB, COLOR/
I noticed that if I send
i2c_write(0x2E, 0x01);
I can almost see the whole frame but the colors then look really funny.
Can anyone help please ?
Thank.
Hi together,
at the moment, i am trying to start the camera via an Arduino-Board. Here’s the code i am sending:
Wire.beginTransmission(0x3C); // address 0b1111000 = 60 = 0x3C
Wire.send(0x03); // sends one byte
Wire.send(0x00); // sends one byte
Wire.endTransmission(); // stop transmitting
But the cam does not seem to change its state at all. Should i be able to watch a change in the current consumption? Usually, i should be able to see an alternating signal on the HD/VD-lines?! I guess there might be a problem in the I²C-communication. Do you know if the cam wants to have repeated starts?
Thank you for your help,
Max
:edit: just noticed that the endTransimission-function returns some error-codes, and now i’ve seen, that my error-code seems to be the “3” all the time, which means “received NACK on transmit of data”… so the addressing of the camera should work, but it is not able to send the data ?!
:edit2: using another i2c-Library, i noticed that the addressing functions are working, but not the write-functions!?
:edit3: woohooo!!! after hours and hours, i noticed, that the cam is using I²C-fast mode and the standard Wire.h library of the Arduino is using standard mode. So i had to change the library as follows:
#define TWI_FREQ 400000L
Now it is working, awesom! The processing of the images will follow the next weeks, i will show images as soon as i got one!
Dmitri, what format do you use to capture video? Do you obtaning JPEG from camera and saving pictures to SD or you use software encoding?
Hi,
I’m trying to buy/build an ultra-light camera board for a near-space balloon project. I have not seen a camera board, other than in this thread, that is as small & light as I believe possible.
Since it doesn’t look like I can buy one, I am looking to build a TCM8240md based camera board. I’ve seen that aerospace combined this camera with an AL440B FIFO. I’m having trouble sourcing this part in small numbers … I figure 5 is enough to get me to a working example.
I’d like pointers to parts suppliers that can source small numbers of this part. Digikey/Mouser/Jameco don’t appear to have it.
Thanks
John

TCM8230md has no JPEG encoding. Raw video data is stored directly to the SD card as YUV411.
Hey guys I have read through this entire thread as I looking to get one of these cameras… I thought I would just give you the a heads up on a different type of camera OV9650 they are available on eb**.com for like 18 bucks and have a great datash**t and come with a breakout board as well!! they are made for the strongarm s3c2440 developement kit… I think I will end up persuing coding using this camera… any way congrats to all the guys who got the sparkfun cameras working!! what a mission…
