I2Ctrabajos

My final year thesis is to interface dirctly the CMOS colour image sensor OV7620 (omnivision) to the DSP TMS320C6711. The problem is that the sensor is controlled by the I2C I want to do so without the use of an FPGA, i must implent the I2C protocol in C Language for the specific DSP. I think that an option is to program McBSP channels to act as GPIO (an example is from texas instruments), where i think to implement the I2C. I need the code be fully fuctional for I2C transition from the sensor. If you need more aplications notes will be in touch. If it is possible there is a need for the ccs files and details about RAM initialization,EMIF and EDMA usage. ## Deliverables Rent A Coder requirements notice: As originally posted, this bid request does not have c...

...equipments. I prefer an uC with ISP capabilities. To verify that there is no volage on the power components, except when is the case, an optocoupler circuit must be provided (or any other solution) and read by the uC. The uC must also supervise a heater and a liquid level in a tank. There must be also a 4 digit display and a 12 keys keyboard which are, phisicaly, at 2 meters from the uC. So, think to a I2C solution or like. Now, the most important part of the project is that the electonic must be interfaced to some coin validators which have BDV and MDB interfaces. These are some serial buses. I will provide all the necesary specifications. The program must control all the functions of the equipment and save some information (like number of actions of motors, ev's and ti...

We need a HASP key solution, only cheaper. Basically it should have a Microprocessor (PIC) and EPROM memory (even I2C). Other solutions are welcome. The memory should be at least 256 bytes in size, but isn't really needed to be bigger than 32 KBytes. It should work as the HASP keys from eAladdin for example (or at least replicate most of their security features), LPT or USB solutions (preferably LPT). What you should offer: The complete schematic for producing the plug, parts names, etc. A Windows driver for accessing the plug (complete source code). A Linux driver for accessing the plug (optional). Some API documentation for using the plug from C/C++ and/or C#, Delphi, eventually Java.

Hi there, I have a requirement for a small FM exciter. It is to operate from 87.5 Mhz to 108 Mhz and must be tuneable in 50 Khz steps and locked by PLL. Ideally, I would like this hooked up to an LCD display which reads out the current frequency, but otherwise if you can make the Exciter accept commands via serial/spi/i2c or whatever, I can interface a uc and lcd to it. This should be designed for SMT in mind as I want it as small as possible (no spider solder hackers please!). Output power should be 1 Watt, however if you can make it variable 1-5 Watt, that would be ideal. Common broadcasting rules should be taken into account (eg, 2nd harmonic -60dB from the 1st etc.), so you should have relevant RF experience. Stereo is not a requirement. Input will be li...

Mini-port driver for Windows or direct code in Visual Basic 6.0 that will report the state of a smart battery to windows. In a laptop computer the I2C bus driver collects this information from a battery directly. This function has to work on a standard motherboard, no battery on I2C bus. The visual basic program that exists is talking to the battery using a serial bus and has all of the standard information about the battery. The Visual Basic program can read all of the standard Smart Battery information and provide it to the driver. Exampe: Percent Power Remaining, alarms (Low battery), time to empty, Battery present and it's information, battery removed. The code needs to work on Windows-XP (W2k) and be able to be called by Visual Basic 6.0 or be calls ...

...Minimum external components required. Not sure if an internal oscillator is stable enough. May require additional crystal and cap. 2. Monochrome VGA output 3. Monochrome Composite output using 3 additional resistors 4. Output type (VGA or NTSC Composite) is selected by tying a mode select pin either high or low. 5. Serial Interface for communication with microprocessor (Basic Stamp, PIC) (RS232, I2C or SPI? not sure, open to suggestions) 6. Graphics Mode is bitmapped 160x80 (if possible). 1600 bytes of memory are used. Each pixel on screen is represented by 1 bit in ram. 7. Commands are sent to the serial port as bytes. 8. Command to set pixel can be sent from the host 9. Command to clear pixel 10. Command to clear screen 11. Command to write character from built in 8x8 c...

...project is made of 3 parts: side - Done by me in ISA or USB protocol. 2.I2C master is embedded microcontroller PIC18F2220 (I2C master) that works as a communicator and manager between the PC and the IOs. 3.IOs. based on the PIC18F258258. The IOs come in 4 different types: Analog input with 16bit AD, Analog Output with 16 bit DA. Binary Input and Binary Output. The Analog input can measure Volts, Current and Resistance. The IOs, once configured to work will continue to work without any requests from the master I2C. When request comes from I2C master, calculated data will be transferred to te I2C master. This data will be transferred in its turn to the PC (ISA or USB) The Protocol for The I2C, HW, Block diagrams and SW flow...

This is for a different project than the other I have listed on this site Essentially I need to control a PLL in a very basic fashion. the chip I have chosen for this project is the ATTINY12L by atmel output is I2C to control the PLL. input to the TINY is 2 tactile switches for up and down . it is to roll over the the start if up passes upper limit set in software and the reverse for down for 62.5khz steps over a 30 mhz range. very basic and very simple. All frequency limits, scanning speed and last frequency used are to be stored in the eeprom location of the TINY. The software is to write its last frequency load to eeprom so at power loss, it knows where it was and can resume from last setpoint PLL datasheet is enclosed Make me an offer. Thanks very

I need someone to write code for a pic16f872. This code is to control a PLL module with I2C, a 2x16 lcd and accept 2 momentary pushbuttons for frequency scanning up and down. and one button to step through LCD display pages. The a/d portion of the PIC receives an analog voltage from the signal strength portion of the pll module and will display a value of 10-100% on the lcd. Battery voltage will also go to a/d and be displayed as actual voltage. Frequency will also be displayed on the lcd. This is my basic description. those interested please let me know and I can elaborate further. I am a hobbyist who can't write it but is willing to pay for someone else to ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source co...
