Hello, I have a project for logging in data with date/time stamp. I just need PIC software for it. It's described as below. The PIC micro controller to be used is PIC16F1455 and peripherals required are USART, USB and I2C/SPI interface for interfacing RTC (DS1307) and external EEPROM (24LC32A or similar). A crystal of 32KHz and a battery of 3V will be used. PIC receives data on Rx pin of USART. I need to save the received data (formatted in messages) with time/date stamp into external EEPROM in .txt format. When this circuit is connected to a windows PC on USB port, it need to open up the saved data like a flash drive. *The circuit will be just connected to 5v,GND and USART signal when in operation. It will be removed from the unit and then connected to PC. I need PIC sof...

Write a labview VI that talks to either a uno or mega ardiuno device that is connected to the pololu minimu-9. The Arduino can talk to the imu either i2c or spi but the labview must use the labview for arduino interface code Labview must talk to the arduino and the arduino must talk to the IMU. Labview must display at least thethree axis accelerations in real time and writ that data to a pc file ( csv or other) at at least 5hz. the csv file must have at least a time stamp for each reading and the three accelerations. The deliverable are at least 1) the labview vi, the arduino sketch, a wiring diagram and instructions on how it works.

Develop a prototype PCB using a Raspberry Pi (RPI) and PIC 32 micro controller (PIC32MX360F512L). Integrate the two controllers using SPI. Use Python for the RPI to communicate outside of the GPIO and use Microchips MPLab C Compiler for the driver development. Also build in eight (8) analog outputs (4-20mA) preferably on the I2C port. Deliverables would include a PCB design including three (3) functional boards, project files for RPI and MPLab.

Short code for RTC..manipulation. 3. SPI initialization code. 4. Short code for SD Card(raw data only .FAT32 NOT required.) thru SPI (We have our custom code....)..
I have got a code that will take a string, split it in 16 char and write it into different blocks of Mifare Classic 1K Tag. I want this code (or write ones own) to be extended so to allow the user to be able to send the string through serial input. This should be pretty easy for someone who know arduino programming. I am using PN532 NFC Read/ Write boards and arduino connect via I2C. Contact me if you need more details and my side of code files.
Embedded C software engineer is needed to write firmware for an ARM Cortex M4 based project. This is a microprocessor based project that involves writing to an SD card, communicating with SPI and I2C peripherals, a graphics LCD, signal processing, power management and a cellular modem interface. We need someone experienced in the embedded environment, preferably in ARM architecture. Please let me know what software development environments that you are familiar with and please let me know if you own any for use in this project. This should be an ongoing project, or series of projects for a good candidate. We have several projects that are fairly involved. We would like someone that can support us with at least 20 hours per week.
Adjust the firmware to work according the operation modes; Write configurations on a I2C external memory; Add support for USB (pendrive) recording and playback of data;

We have a micro-controller with very nice features below. We would like to make it Arduino compatible. Need porting of Arduino IDE to generate code to work with our micro-controller. * 7-stage pipeline Sparc-v8 LEON3 processor * IEEE-754 compliant FPU * Global Navigation Satellite System Signal Processing Engine * 192KByte SRAM * 1MByte Flash * UART x2 * I2C x 1 * SPI x 1 * GPIO x 8 * PWM x 1 One who is interested should first download Arduino IDE and Bare-C Cross Compiler for LEON3 from below links, play with it a bit, to see if indeed have sufficient knowledge and experience to do the porting for us. We hope to have the porting done in 1 ~ 2 months, before 2013 ends.
GOAL OF THIS WORK is to rework our existing code to a working new code. For example loosing all the I2C code, “glueing” the 3 uP codes together and make a new functional unit with the same possibilities. Later on, we can work on improvements. We will provide of course existing code. Just rework it to good code! Detailled project: see documents.

Hello I need to design a PCB that can capture from 8 camera sources on the same time and offers the output in any digital output usable by the rest of my project. I can deal with i2c, usb, or ttl/rs232. OS I use is ubuntu. The engineer will help selecting the right components; and design the PCB down to the BOM level. We may extend the work to create a prototype or not. Happy bidding.
I need a simple C script to read sensor data from a INA219 chip via I2C ( ). Everything is already written and documented for the 3.x kernel module ( ) I use 2.6.32-5-486 Kernel and dont need a kernel module, simple c code that uses the #include and reads the data is enough. I am currently stuck because all examples and kernel modules i found use i2c_read functions but due to kernel and smbus in i2c-dev.h I have to use i2c_smbus_read_i2c functions. I am not a C programmer - I can already read registers but it seems that I mismatch datatypes, bits and bytes.

...eagle schematics i understood some parts of it, not everything and the main reason i need one of you is because i only have one circuit board. The schematic goes attached, the information about the product is here: The creator says it's easy to connect it to the Arduino, so i supose it's easy for who understands this well. P.S: this is an i2c protocol connection, so SCL and SDA should connect at Analog pin 4 and 5 (A4, A5), it should not be a problem to connect this pH meter to the same Analog inputs, as long we define the right addresses. Thank you very much. Kind regards....
You are required to write a small Labview program to impersonate the attached SI7005 silicon labs, so we can test the main unit that acquires the signal. The signal is acquired thorugh the I2C protocol. Basically the front panel will have two Integer inputs, temperature in °C and Relative humidity in 0-100 % scale so when labview is polled by the main unit, it should feed the user-specified values to the main unit via I2C. The communication protocol is implemented according to the datasheet by silicon labs. We were planning to use the attached NI USB8451, but fell free to advise. Delivery includes the Vi file and some troubleshooting assistance in case the Labview program does not work as planned.
