  • Forum Post: I2C Interface for Pico 2 Development Kit

    Pete Sites
    I have a Pico 2 development kit that I am experimenting with. I would like to perform some simply programming operations that configure the unit to display various internal structured light patterns. I have NOT been able to successfully execute any I2C commands. My setup is as follows: I am using a flex...

    Steven Mattheussen
    Hi, I have DLP Pico Projector Development Kit which I want to use to create texture on solid surfaces in order to have more structure for 3D vision. I was wondering if there is a relative simple way to use custom splash screens. In my set-up it is not possible to connect to HDMI, so I'd like to...

    Steven, Welcome to the DLP&MEMS E2E forum. There is no provision for user-defined patterns except via the HDMI video input. However, there are internal patterns which are available for structured light applications. Please refer to the documens DLP® Pico Chipset v2 Programmer’s...

    24_Sos W_oo, The Pico Kit V2 does not come with software. It is capable of displaying 640x480 @60Hz video provided through the DVImini connector from a suitable video source. This can be a computer with a DVI output (DVI to HDMI adapter or cable required), or from a laptop through a VGA-to-DVI/HDMI...

  • Forum Post: How to use PICO V2 through i2c

    tian ouman
    Hello, We have both a Beagle Board (xm) and PICO kit V2. We have routinely used I2C to setup PICO V2. I can not find I2C commands like "bus3-i2c 0x1b wb4 0x05 0x00000007" How can I get these I2C commands? Thanks in advance, ouman

    hi , I want to know how can I use any i2c-tools or code in linux on beagboard to set pico2, I write 0x1b 0x08 0x00000001 to i2c-3, the pico2 is not controlled. I write 0x36 0x08 0x00000001 to i2c-3, the i2c translate is refused. Programmer's Guide is no use for me ,beacause I can not...

    Ouman, The correct I2C address is 0x1b. The format is: bus3-i2c 0x1b wb4 0x04 0x00000001 where: 0x1b is the I2C address of the Pico Kit V2 wb4 mean write 4 bytes 0x04 is the register to write to 0x00000001 is the data (32 bits - 8 hex digits) written to the register The command...

    Ouman, Do a search for i2c-tools (package for Linux). The bus3-i2c command is implemented by this package. The package can be installed in Angstrom Distribution Linux (http://angstrom-distribution.com) for the BeagleBoard. I recommend that you look at the forums for http://beagleboard.org...

    Pascal DLP
    Hello Wierong Mo. The Pico Kit v2 can be controlled via the I2C port available on the AUX port. TI does not provide software to do so. If the NI-DAQmx card provides the I2C protocol, then this should work. Please refer to DLP® Pico Chipset v2 Programmer’s Guide (Rev. A) ...

    Pascal DLP
    Weirong, I have no experience with the NI USB-8451 card. If it provides I2C, then it should work. Try setting the speed to 100 kHz (though 400 kHz should work -sometimes it is best to use the slower setting). There are also some differences between I2C implementations in how the I2C device address...

    Alan, I assume that you purchased the TI USB-to-I2C/GPIO Bridge. The documentation available for that product is: http://focus.ti.com/lit/ml/sllu093/sllu093.pdf (you can download this from the DigiKey site; it links to this address.) Is that where you see the description? Perhaps the schematic...

    Pascal DLP
    Alan, If you can not see any signals on the AX_SDA and AX_SCL when you write from the PC (through the adapter), then the adapter and/or software is not sending signals. Pay particular attention to the AX_SCL - whenever the PC is trying to send data, it will put a clock on this line. If you are...

    I see in the documentation (dlpa021.pdf) that there are Gray codes embedded in the projector. Are these patterns in the DLPC100 controller, or in the DLPR100 ROM? Long-story-short: I've had a lot of success doing phase-shift imaging (sinusoid) via the HDMI connector (via Mac laptop) but am hoping...

    These chaps maintain a list of compatible chips than can be detected by the i2c-tools utility. I notice there are a number of Texas instrucments sensors, but no mention of projectors. They do make a request on their website for you to send them the info so that future releases of their sensors-detect...

    Hi Pascal, you must be getting sick of all these questions! I admire your patience! I'm a bit confused, as the DLP® Pico Chipset v2 Programmer’s Guide (page 8) for the Pico says the address of the pico 2.0 is 0x36 but you say its 0x1b e.g An example of a register write to device...

    Hi Pascal. I understand how the frames should be interpreted according to the manual. I've written about 4 programs to generate content for the projector. The first one takes as input a monochrome video (1 bit monochrome) and then analyases 24 frames at a time, and simpy creates a pixel in 24...

    1 more test. This time I'm just showing the desktop projected on a piece of paper, before and after the ardinuo sends the commands. What I notice is that it appears the desktop does get cropped to 480*320, but....then is getting stretched to almost the full size of the projector, which tells me that...
