I require the schematics and software code for a remotely monitored data acquisition sensors that can directly connect to any internet based router/modem and upload a file to a >> specifiable << folder on my server every 5-minutes This file would contain the binary series of data representing the analog to digital conversion of an electromagnetic sensor coil. Further, the devise should incorporate a real time watch that can compare the time it keeps against the server’s remote time and alert if there is any difference greater than 1-minute between the internal time it keeps and the server. The data acquisition sensors MUST be low cost and cheap to mass produce.

Hi, I have developed the hardware for an acoustic Active Noise Reduction module. The module accepts a microphone input which drives a DSP (ADAU1772 by Analog Devices), then drives a speaker. The idea is that the software in the DSP applies an inverse transfer function of the microphone and speaker combined, so as to present a 180 degree phase shifted sound out of the speaker, which cancels the input sound to the microphone. I have a basic profile that works, but it is limited in the fact that the phase of the mechanical system starts at 0 degrees out of phase at low frequencies and extends to about 360 degrees out of phase at 2kHz. To develop an inverse DSP transfer function would mean a phase lead filter or something along those lines where the phase lag is the most at low f...

...the imagination. My terminology may be a bit suspect, but will do what I can to clarify what I can. The 1984-2004 Ford EEC-IV and EEC-V PCM uses the 8061/8065 MCU, with the primary difference being that the EEC-V uses Bank Select control for up to four 64kb banks. The core feature of the product line is that it acts as a Parallel Slave Port, but with additional capabilities. I want to add Analog inputs (up to 4) and use Dual Port RAM, that can sit directly on the Service Port (J3) and feed the PCM. It should load the currently active calibration from Flash memory, at power up. Currently this is controlled by a BCD switch, but would possibly like to use software selectable setting. I am leaning towards a MCU (PICxxx, STM32) to eliminate multiple components that are used ...

To und...Arduino IDE and look at all the examples The IDE is free from version 1.0.5-r2 using the 12 inputs and the AO analog input the purpose is to display messages on the built-in Serial monitor based on either a single input or an analog value. The voltage on pin AO would be 0-5dc There would be 11 messages based on a value spread of 0-1023 so each message would be a span of 93. So message 1 would be triggered if the analog value were 1-92 message two would be 93-186 and so on Only one message can be displayed at any given time, and only displayed once If pin 1 is true then it uses pin 2-12 for discrete message triggers instead of the analog input same rules would apply. I am sure there will be discussions for additional information, but ...

Design the circuit for a GPS tracker using SIM908 and a cheap MCU. The SIM908 is a single module that includes both a GPS chip and a GSM+GPRS modem. It should have on-board flash memory to hold buffered data when no cellular signal and also to store data during OTA. Please provide two digital inputs and one digital output. No analog inputs are required. It should also include a charger for a 1500mAh Li-ion battery but the board should work without the battery also. The entire BOM should cost $15 in quantities of 1000 pcs.

We are after a software/hardware engineer to implement the OpenDNP3 functionality on a small Arduino module. The Arduino is to act as a data logger (DNP3 slave) and must also have the I/O board in place so that it can measure and record events for both analog and digital sensors. It also needs the real-time clock module (which will be updated from a DNP3 master). Finally, the design needs to be such that it can be powered off lithium batteries (3.6V) and run at ultra low power levels so as to maximize battery life. Hence sending the unit into deep sleep, and also only powering sensors when required would be key. Full functional descriptions of the DNP3 and sensor requirements will be supplied.

Hi to all, I need a program which it can count external interrupts generated by a reed sensor in one hour while the Atmega328 is sleeping and after the time has passed send the number of interrupts, temperature from a sensor -analog read- voltage from output regulator (5V) and voltage from a voltage divider (10V) to a function. After the time is passed the interrupts counter will be reseted. The GSM functions is done. I will provide current code. This work needs ~30minutes maximum of work because arduino IDE as you know provides ALL the libraries. Easy job. Cheers, Gabriel.

Write C++ software compatible with the MPLab IDE for a PIC16F877 controller to convert analog inputs to a modbus RS485 output. Specifications are as follows: - Read eight analog voltages, 0-5Vdc. - Upon startup, the system should check if any DS18B20 temperature sensors are attached to the inputs. If so, it will measure temperature on those inputs. If not, it will default to measure voltage. DS18B20 should operate in parasitic mode. - Set up registers 1 - 8 for the analog voltages and/or temperature measurement. - Provide DIP switch selectable baud rate, parity and stop bits. - Provide LED's to indicate the following: - Heartbeat. This should indicate if system is operating correctly or if it is hanging. - Write indication. Shows when the syste...

...modules are each location. -------------------------- Each hardware or module has two options. Input and Output. Inputs are always on the left side of the hardware/module icon and outputs are always on the right side of the hardware/module icon. Each module can have various types of inputs and outputs. Each type of outputs should be set in the preferences section of the applications. i.e. Analog Video, HDMI, SDI, ASI, RF etc etc..... each one should be a different colour, and used as a standard throughout the application. Once the hardware/module is set with its inputs and outputs that becomes part of the inventory of hardware that we can drag and drop from the inventory drawer. Ideally I would like it to automatically space and make the lines look nice. Lines ...
