Friends,

Do you know init code for 2MPix camera module MT9D111 ?
Any informations will be very appreciated,

thanks

I think you should try looking at Micron's website for code

Hi,

This is my init code for the MT9D111 module available from ebay

  /* soft reset 
   1. Bypass the PLL, R0x65:0 = 0xA000, if it is currently used.
    2. Perform MCU reset by setting R0xC3:1 = 0x0501.
    3. Enable soft reset by setting R0x0D:0 = 0x0021. Bit 0 is used for the sensor core reset
    while bit 5 refers to SOC reset.
    4. Disable soft reset by setting R0x0D:0 = 0x0000.
    5. Wait 24 clock cycles before using the two-wire serial interface.

Hi,

Check the included source code.
I've tried to configure the MT9D111 in such a way that it outputs JPEG data as slow as possible using a adaptive PIXCLK.

This is an initial picture how I connect the MT9D111 to an mbed dev board:


CLK and RST are accidently swapped in this image.

The code provided in the zip is still testcode. When everything is stable, i'll post an update.

Does anyone have microcontroller programming software for STC15F104W (core 8051, 4 k, 128 byte, 6 I/O pin, UART ... DIL8), that works?

Hi I am looking for a assembly language program for a digital decimal counter. Time counts max limit of 2 mins starting from 2.00 mins and ending at 0.00. time is to be displayed on 4 7-segment LED displays. Edsim51 simulator to be used. Thanks
